Wireless — Are We Getting There?
By Scott Tiner rAVe Columnist
Back in the fall, I wrote a column about the Microsoft Surface 3. At the end of that column I teased a bit about what I thought was one of the best features of the Surface, but warranted a separate column. Specifically, the built in WiDi or MiraCast. Since that time I have gotten to read more about the tools, and use it more regularly.
My experiences are hopeful, but mixed. First of all, it is actually rather difficult to find information about WiDi and MiraCast. I have done a fair amount of research, and understand the basic principal of both, but also am unable to determine the technology behind each. In fact, despite a fair amount of research, I can not tell you whether the Surface uses MiraCast technology or WiDi technology. This is important because as we try to implement these into our environments, we need to understand how they work. Here is an example. I bought a NetGear Push2TV. This is a receiver for MiraCast and WiDi. I can connect to it with only three easy taps on my Surface and wirelessly display on a large monitor. However, on occasion, I can not see the Push2TV as a source from the Surface. Certainly, a 85 percent success rate is OK for the lottery, but not for my classrooms. The only way for me to get a good consistent working connection was to disable some feature in my networking control panel. Hmmmm… that is odd. After all, these wireless technologies are supposed to be independent of your Ethernet networks, so why do these settings matter? The fact that I can not answer this question leaves me thinking that it is not the right tool for a production environment.
That realization, and a request from a customer to project wirelessly got me to investigate the AirMedia from Crestron, again. As Crestron typically does, there have been some recent firmware upgrades to the device that have improved its reliability and function along with some additional features. The only knock on the AirMedia continues to be that you need to download something, which is contrary to the promise of the MiraCast/WiDi in that it is just built in. However, the download is a .exe, you don’t actually need to install anything. So, most people who are adventurous enough to try wireless video will be capable of the download. Also, as Crestron sometimes does, they snuck some true gems in with the firmware upgrade, but don’t publicize them. This time they added tools to allow a “moderator” to control the AirMedia as multiple users connect. So, whether you are in a classroom where students are using laptops or a lab setting, where students are installed computers, they can all connect simultaneously to the AirMedia. The instructor, or “moderator” can see a list of everyone connected (by Windows login ID) and can decide which of those computer he/she will show. The instructor can quad screen the projected image, so to compare multiple work of students at the same time. Finally, for those large lecture halls, or rooms where not everyone has a great view of the projection, AirMedia has a “remote view” function. This allows you to view the output of the AirMedia on your own computer, via a web browser. My experiences with these tools show them to be very reliable and easy to use.
So, yes, I planned on writing a column about the Surface and wireless video, and instead wrote one on the AirMedia. One of my major concerns with the MiraCast/WiDi is that the technical information is so hard to find. I worry that perhaps the companies and groups who started these initiatives are backing away from them. Also, I have real concern about putting in equipment that is so difficult to get information about how they really work. While the AirMedia is not a tool for showing full motion video, it does a decent job of keeping up with frame rates, when showing PowerPoint or Excel, for example. In fact, we have starting installing these in presentation spaces and classrooms, and modelling them for our customers. They are truly, the first reliable and usable wireless video tools I have seen for the Windows environment. Leave a Comment

Big Idea 2015: Automation for the Perfect Classroom
By Richard Blackwell
Foreword: My youngest daughter attends a new public charter where I volunteer more time than I can afford as the “Technology Guy.” The students were issued on day one Chromebooks and Kindles, and they do very limited work with paper of any sort. I worried would all the technology and apps come together, but recently she commented to me “Dad sometimes we learn so much I can barely keep up.” She never said this before. I think the technology is working.
Just ten years ago, a white board was the only media presentation method for most classrooms in the U.S., and automation of any type was seen in less than 10 percent of all classrooms. Having been part of hundreds of classroom refresh projects over the last few years I see the budgets, speak with administrators, work with support technicians, and chat with students using the spaces, so I have a ground level experience of what really makes sense for practical cost effective automation design in most of those rooms.
To start lets identify three groups that classrooms fall into from our installation experience;
- Standard use classroom (90 percent) — seen in the title image above
- Mid-sized multimedia and distance learning classroom (20 percent)
- Large theater classrooms (5 percent)
This breakdown is based mostly on automation complexity (not size necessarily). Type 2 and 3 are very custom, but represent a small group, so we will focus on the 90 percentile group that generally gets the least attention because of the perceived high costs for automation.
At least two factors have greatly effected the design of the standard classroom over the last few years: conservation measures mandated by governments, and a significant drop in automation costs as manufacturers design for these spaces. Because of the need for green, both HVAC and Lighting management have become much more common in these spaces where it was until very recently never considered or affordable.
If you are considering a classroom refresh, or designing new spaces, please let me share some real experience that may affect your plans. Here is what you should include in your space planning that will allow you to get the most for the least cost (you may be surprised how much is possible);
- Automation — Use a local automation controller that is Ethernet connected, with on-board lighting control and occupancy inputs. Central automation (while better than no automation) increases the single point of failure concerns as well as long cable runs. I recommend distributed intelligence because it adds room located lamp control relays and Input/output points for greater local automation and sensor inputs. Many typical controllers are able to manage multiple rooms, so don’t assume one controller per room.
- Lighting — Use a simple four-button, low-voltage switch on wall near door. Three buttons to control individual zones on/off, and the bottom button is All Off. Optional duplicate switch(s) near second door and or instructor station. If any zones are made dimmable, then the assigned button uses press and hold functions to dim up and down instead of just on/off:
- Front zone 1 to light instructor and whiteboards. Turn this zone off for projectors or display presentation. Button 1 on wall switch.
- Main lighting for room on zone 2. Turned on with occupancy sensors and wall switch button 2.
- Lighting in front of windows extends main lighting on zone 3, but switched off to harvest light on bright days. Button 3 on wall switch.
- If no windows, then zone 2 and 3 will both be main lighting on alternating rows. Only one row will turn on with occupancy.
- Optional 4th zone can be used for podium/instructor lighting, door lamps, or custom wall and bookshelf lighting (use button 4 on switch instead of All Off).
|
- Occupancy — Sensor turns on main lighting on zone 2 (and no others). User then chooses additional lighting if desired. There is a growing trend not to turn ON lighting automatically, but to instead require the user to activate lighting IF desired. Safety, security and common sense should always be used when making a decision not to automate lighting, of course.
- Vacancy turns off all lighting. You need good coverage for motion, so consider overlapping sensors to ensure full and complete coverage.
- Additional possibilities for lighting automation include lights on for fire or security alarms. While a stand-alone occupancy controlled system is greener than no system, don’t pass on connected lighting.
- HVAC — The automation system should be connected directly or indirectly to the Building Automation System (BAS) to share occupancy status with HVAC control of that space. BACnet is or should be the method of communication. If a BAS is not in use, then consider an AV or light monitoring application to enable remote control, or alert staff when equipment fails.
- Presentation Automation — Consider using an 80″-plus display. For media input use, Google Chromcast (or similar), which will automatically turn on the display when a laptop selects it (basically the same works for newer projectors). I push towards the larger displays to get away from projectors and the additional support needs they bring, but you often need 80″ to make the switch. The display will turn off with no use automatically.
- More is better — IF there is a little more budget, then here is where you can spend it by replacing the passive display with an active whiteboard. You could pull HDMI cable to the instructor location, but the cable connections are high failure points and tethers the instructor to the podium, so the Chromecast is the laptop interface. And yes, the students can also connect to the display using their tablet or laptop. There are more expensive ways to connect the presentation source to the display via switchers, but this room design is for the masses, not the elite.
When this simple design is employed the room is green, easy to use for instructors, easy to support by the AV staff, and our, perhaps most importantly, acceptably cool by our tech savvy generation of students.
In addition to Richard’s day job, he is founder and moderator of the Open Source Classroom Automation site on Google. Leave a Comment

Microsoft Has Figured Out What Sharp, InFocus, SMART Technologies and Clary Icon Already Knew
By Gary Kayye rAVe Founder
Although SMART Technologies invented the interactive whiteboard market, and therefore indirectly invented the interactive display market, companies like InFocus — with Mondopad — and Clary Icon as well as Sharp have developed it into more of a mainstream product category in recent years.
So much so that Microsoft has now, well, copied it — but, have they even made it better?
Microsoft entered the large-screen interactive LCD panel market last week with the launch of what it’s calling the Surface Hub. And, the way the mainstream press is eating it up as if it’s an innovative, first-of-its-kind, well, interactive LCD panel, you’d have thought that Microsoft would have invented it.
They didn’t.
Smart started back in the late ’80s making interactive products and by the end of the ’90s, they had a 92 percent market share in the electronic (or interactive) whiteboard market in schools, worldwide, and nearly an 80 percent market share in the corporate market for the fancy whiteboards. But, since then, we’ve seen LCD panels get bigger and cheaper and companies like Sharp and Clary Icon have taken chunks of the market and have helped re-invent the category. Then, in 2013, InFocus launched the Mondopad.
So, what is the Microsoft Surface Hub?
It’s an 84” multi-touch LCD — remember, Microsoft, a few years back, bought a company called Perceptive Pixel in 2012 — they were probably, at that time, most famous for providing CNN with their big multi-touch touchscreen during the 2008 and 2012 election seasons. Then, Fox News bought a plethora of them for Shepard Smith’s Fox News Deck set back in 2013. Well, last week, Microsoft said they’d used the Perceptive Pixel technology to launch a whole new series of Surface Hubs that range in sizes from 55” to 84” and includes the ability for two people to interactive (true multi-touch) with the screen simultaneously — both can use septa styluses at the same time, too. Additional features include wireless transmission and connectivity of laptops, tablets and phones, split-screen display of content (what we commonly refer to as BYOD or huddle-room wireless content sharing in the AV market) and it’s integrated with Skype for Business — so you can easily connect a videoconference.
Of course, being from Microsoft, it’s running the latest version of Windows — in this case, 10 — and it’s a 4K resolution display (3840×2160) — and includes two built-in HD cameras that can shoot the periphery of the room or a person/presenter and attendees simultaneously and it’s integrated with microphones and speakers. Basically, it’s an 84” AV system in a box with the ability to send content via HDMI, VGA, over the network or wirelessly.
So, is this a big deal?
Yes.
Will it kill SMART, InFocus, Sharp and Clary Icon?
No. But, it will make them each go back and re-engineer their individual systems. All four of them are sure to show up at InfoComm with a better product than they have now. None of them have exactly what Microsoft has.
Then again, we don’t know what Microsoft is going to price it at — remember, it’s an 84”, professional, purpose-built 4K resolution display — not cheap. It won’t be $5,000 or $10,000. Think a lot higher — for now.
And, there’s a market for what everyone else has now.
Yes, 4K is nice — and makes sense for an 84” where you’re likely going to mostly replace projectors. And, Microsoft is rumored to be working on debuting a 100” by InfoComm — so bigger is better.
But, not every room needs an 84” and not every meeting needs 4K. Certainly where a lot of the Sharp and Clary Icons are going — schools, don’t need that resolution right now.
Sharp has an entire line of what they call the AQUOS BOARD displays from 60-80” displays and most of them can manage four people using them simultaneously. Certainly, they aren’t integrated with with Microsoft Windows on-board, but they’re specifically for electronic whiteboarding, displaying and sharing presentations, real-time annotating and collaboration — thus, 1080p native displays work well here. And, they aren’t $20,000 — the price that most think Microsoft will enter the market at. In fact the Sharp line ranges from $6,000 to $12,000.
InFocus’s $6,000 – $12,000 Mondopad is probably most like the Microsoft product. Also available from 55” to 80”, the Mondopad has Microsoft Windows (version 7) and Office integrated right in the product and is already like a giant Microsoft Surface tablet — in fact, load Windows 10 on here and they’ve got 80 percent of what Microsoft is launching. Missing? Well, the Mondopad is 1080p, uses one camera for Skype and SIP calls (and since’s it’s H.323 it, too, can connect to Polycom and Cisco) and the user-interface is different. But, by InfoComm, this product will likely be very close to the same thing that Microsoft will show in their booth in June.
Clary Icon’s H1 product looks, aesthetically, a lot like the Microsoft Surface Hub, but it’s only available in 40”, 60” and 70” versions and is also priced in the $7,000 — $14,000 range. Also using Windows 7, the Clary Icon products use the Hitachi StarBoard panels and includes videoconferencing (and not just Skype — they can do Polycom and Cisco, too) and they can do wireless collaboration, too. But, their camera is separate, their resolution is, too, only 2K or HD and their software-interface isn’t as slick as Microsoft’s — ironic to even write that when Microsoft and “sick interface” haven’t likely been put together by too many tech journalists in years — given the blue-screen-of-death phenomenon.
Then, there’s SMART. SMART is the company that will likely be able to copy the Microsoft product the closest when they launch, yet another, 4K version (their first debuted in late-2013, actually). They’re already Microsoft Lync — as most of these products are – and they have one of the most familiar user-interfaces of all the interactive LCDs on the market. Everyone else looked at theirs first at some point in development. In fact, SMART’s current 84”, when integrated with the Meeting Pro software, looks — spec for spec — nearly identical to the Microsoft product. And, SMART already sells it through AV integration.
And, unless Microsoft somehow limits the Windows 10 compatibility for any of these manufacturers, look to see them all add 4K versions of their interactive LCD’s by the end of 2015.
But, price will be a factor. If Microsoft chooses to come in and steal the market at $15,000 or even $10,000, that could present a problem for everyone — unless they can match the resolution.
One thing they will all have going for them that, ironically, Microsoft has working against them — Sharp, InFocus, Clary Icon and SMART all have better brand performance reputations than Microsoft does in the world of AV Now, Windows 10 is, by all accounts, the company’s best-ever operating system and lens itself well to a giant Surface Tablet like the HUB. But, It’s still Microsoft and that will either be a blessing or a curse — from a marketing standpoint — for themselves.
Either way, we’ll know rather soon as the Integrated Systems Europe (ISE) show kicks-off in two weeks and Microsoft will be there and will certainly show all their AV wares at InfoComm in June in Orlando.

Light Color: the Efficient and Happy Office Space
By Richard Blackwell
The lighting industry is of late highly focused on energy efficiency and cost of ownership. However, some long standing research, and some recent work point to a much greater savings in worker efficiency if the type of light and color of light are taken into account along with efficiency.
In the ’70s, fast food chains performed market research to investigate how customers responded to various colors in restaurant interiors and logo with interesting results. Some of there research found the following effects; in general, yellow, red, and orange are “exciting” and green, purple and blue are “calming” colors. Even the military got into the game with it’s own research, and soon after made paint color changes in ship common spaces, and light color most notably changing “Battle Lamps” from red to a shade of blue.
This chart shows Kelvin Color Temperatures and their effects in residential settings.
The Natick Soldier Research, Development and Engineering Center (NSRDEC) concluded in a recent study that LED lighting fostered a positive mood, increased alertness, and resulted in faster performance on visual perceptual and cognitive tasks. Soldiers working under fluorescent lights typically felt less alert, more fatigued and more depressed over time. They also demonstrated slower response times on cognitive tasks.
Researchers have studied the question of how lighting conditions affect mental stability for decades. In the 1940s, Luckiesh and Moss studied how fifth- and sixth-graders in well-lit and poorly lit classrooms performed on the New Stanford Achievement Test. Those in well-lit classrooms scored significantly higher than those in poorly lit classrooms. Since then, numerous researchers have studied the effects of fluorescent lighting. In a 2002 Guardian News article, Michaele Wynn-Jones investigated fluorescent lighting in prisons. Wynn-Jones concluded that fluorescent lighting is a likely cause of the headaches, depression and sleep disorders prisoners frequently experience.
According to researchers at the H.E.S.E project, the most common symptoms of having been exposed to too much fluorescent lighting and too little natural lighting are headaches, mood swings, irritability, insomnia and inappropriate behavior. John Ott further notes that continuous exposure to fluorescent lighting can lead to a depletion of the brain chemical serotonin. Known as a mood stabilizer, serotonin helps to keep mood disorders such as generalized anxiety disorder and depression at bay. Depleting the natural resources of serotonin in the brain can thus have serious and lasting consequences for emotional stability… more.
In conclusion light color makes a significant difference in the moods, behavior and work efficiency of all those present, so the next time you are looking at a simple lighting refresh or for easy methods of increasing office efficiency you should consider replacing fluorescent with white and color variable LED lighting your space.

Rotel Introduces New RSP-1582 Reference Surround Processor Rotel Electronics has just launched what it’s calling a “reference” surround processor: the RSP-1582. Rotel says the DACs in the RSP-1582 preamp/processor consist of six 24-bit/192kHz Wolfson WM8740 chips, four dedicated DACs for the front left, front right, center and subwoofer channels and shared stereo DACs for the rear and surround channels. Also included is a Texas Instruments PCM1804 audio-performance analog-to-digital converter (ADC). The processor is 7.1.
Multi-channel soundtracks are decoded by a Texas Instruments Aureus TMS320DA808 DSP chip with a 10-channel Parametric Equalization (PEQ). Digital inputs include: three optical, three coaxial, PC-USB input supporting 24bit/192kHz audio and an embedded aptX Bluetooth receiver for CD quality wireless connectivity.
The RSP-1582 has an analog Bypass function for relevant input signals, which circumvents the DSP section to obtain the purest analog signal path. The analog inputs include phono stage, four auxiliary, XLR balanced input, 7.1 channel input and six conventional stereo analogue inputs. The analog pre-outputs are presented on fully balanced XLR and unbalanced RCA connectors, both with twin subwoofer connections. The volume control allows for fine adjustments of level in increments of 0.5 dB.
The RSP-1582’s eight HDMI 4K video pass-through inputs utilize a Silicon Image Sil9573 2K/4K HDMI transceiver. There are also two HDMI 4K video pass-through outputs (one ARC/CEC enabled). And front-panel HDMI input with 4K video pass-through.
Other features include:
- 7” TFT display on the front panel
- Front-panel USB input for Apple devices with 2.1 amp charging capability
- RS232 and IP network interface for control
- Two IR output connectors for IR pass-through and wired IR remote input

Christie Announces Boxer Projector Series Christie’s new Boxer Series will officially launch and will make its worldwide debut at the Integrated Systems Europe (ISE) show in Amsterdam, but we have the details now. Technically, there was a private launch back in November and Christie has already taken orders for more than 200 projectors — without a public launch!
The first offering from the new Boxer Series, the Boxer 4K30 has six 450-watt mercury lamps delivering 30,000 center lumens. Weighing about 150 pounds (68 kilograms), the Boxer 4K30 can be carried by two individuals and is designed for rental/staging fleet or permanent installs. With built-in Christie Twist, images can be blended and warped from multiple projectors onto curved or irregular surfaces without requiring an external solution. Housed in two 3-lamp cartridges, the six long-life mercury lamp modules are easy to handle, maintain, and change and stock, which means a better return on investment and less consumables.
Users can monitor the lamp hours and serial numbers through Near Field Communication (NFC) with each lamp and it uses the Christie TruLife electronics package so it natively handles 4K signals as well as HD signals, with on-board up-scaling to 4K.
Christie Boxer Series connectivity includes 3G-SDI, HDBaseT, Display Port, DVI-I, HDMI, VGA and five BNC, plus a color LCD preview panel readout and a complete lens suite.
It will ship in April. Full specs are here. Leave a Comment

Extron Ships ShareLink 200 Wireless BYOD Collaboration GatewayA couple of months ago, we wrote about Extron’s entry into the wireless sharing world and told you how this one was different than those from Crestron, Barco and AMX since it includes a moderator mode, 30 fps video playback and because of the fact that you can share content to up to four ShareLink receivers at the same time.
Well, they are now shipping it. Like the others, it’s using the AWIND technology, but that’s where the similarities stop. Extron’s ShareLink 200 Wireless Collaboration Gateway supports devices include Windows and OS X computers as well as Apple and Android smartphones and tablets. ShareLink technology provides simultaneous display of presentations, images, documents, and other content from up to four different personal devices, eliminating the need to constantly change sources during a session. Content from a single device shows full screen, and content from multiple devices appears simultaneously in four windows on the display. Any user can share content and control the presentation when it is set to collaboration mode. A moderator mode ensures only approved content is displayed. Designed for professional AV applications, this wireless gateway also includes many integrator-friendly features such as an integrated wireless access point, Power over Ethernet — PoE, and antennas mounted on the front panel. The ShareLink 200 Wireless Collaboration Gateway can be used to create a stand‑alone wireless collaboration and presentation system or to add wireless presentation capabilities to a variety of wired AV system designs.
A unique feature called WebShare enables content to be sent over the network to a Web browser on each attendee’s personal device. WebShare is useful if the sight line to the display is impaired or when slides need to be saved for future reference. ShareLink technology also allows a Windows or OS X computer to communicate with multiple ShareLink 200 units on a network to send the same content to as many as four displays. This is useful for larger spaces with multiple displays or to support adjacent rooms used for overflow. For easy integration into modern digital and legacy analog systems, ShareLink 200 includes HDMI and VGA video outputs to support a wide variety of display devices and system switchers.
Here’s a good demo of how it works. Leave a Comment

Medialon to Launch New Overture Control System at ISE Medialon’s new Overture is being marketed as a first of its kind “enterprise-class AV Control Software.” Medialon Overture is an effective enterprise-wide AV control software. It controls, monitors, and automates thousands of AV devices in multiple locations, integrates with IT services, and delivers a dedicated person-based user interface.
Overture eliminates the cost and burden of hardware boxes by controlling all AV devices via TCP/IP. It is “company wide,” centralized, connected to Microsoft Exchange for room booking, Microsoft Active Directory for credential management, SNMP for logging, and Building Management systems for environment control and energy savings.
Medialon says that Overture uses standard IT technologies both for hardware, allowing the use of smartphones and tablets as user interfaces, and for programming,
allowing users to set up and edit their Overture system themselves. Overture is database-driven and relies on configuration for most of its functionalities, eliminating heavy programming. User interfaces are automatically and dynamically generated from information in the database, user credentials, and room booking information.
Medialon will demo Overture at ISE in the Comm-Tec stand at ISE 2015 (#2-A42) but all the details are here. Leave a Comment

BenQ Unveils Latest Classroom IQ SolutionsThe new BenQ MX723 is aimed at small- to medium-sized classrooms in that it’s an XGA resolution (1024×768) 1-chip DLP projector that’s spec’d at 3,700 ANSI lumens and 13,000:1 high contrast ratio. Integrated with both vertical and horizontal keystone correction, as well as 1.6x zoom functionality, the MX723 automatically adjusts lamp power by up to 70 percent to use just the right amount of brightness, resulting in up to 5,000 hours of lamp life without compromising picture quality (something they call SmartEco). To further reduce power consumption, an “Eco Blank” mode allows teachers to blank out the screen whenever projection isn’t needed, while a “No Source Detected” mode automatically lowers brightness to 30 percent when no signal has been detected for more than three minutes. In “Standby” mode, the projector lowers power consumption to less than 0.5W during periods of inactivity, providing even greater energy savings and further lowering TCO.
If you need wide-screen in a classroom, the WXGA resolution (1280×768) ultra-short-throw MW853UST+ plus is spec’d at a 10,000:1 contrast ratio and 3,200 lumens. This projector is also integrated with BenQ’s PointWrite technology — allowing up to four participants to collaborate simultaneously on screens as large as 120 inches. Featuring auto calibration, the tool allows teachers and students to interact jointly via enabled pens or finger-touch technology on any type of projection surface for effortless interaction. Also equipped with 3D, PC, dual HDMI, and Blu-ray connectivity in addition to two 10-Watt speakers.
We’ve already written about the BenQ’s HC1200 projector as it’s the industry’s first projector that’s specifically engineered to follow the sRGB industry color standard right out-of-the-box. BenQ says that by combining 100-percent sRGB color accuracy with up to twice as much ANSI contrast than typical LCD projectors, the HC1200 reproduces images that look as bright as top-rated 4,000 lumen projectors. Now, BenQ is pushing this into educational application were color-accurate projection is required.
BenQ’s latest IFPs (flat-panels) bring multi-touch technology to a new 70-inch RP702 HD (1920×1080) display that features 10-point multi-touch technology with responsive feedback. BenQ says the panel’s ZeroFlicker mode reduces fatigue and protects students’ eyes during extended viewing sessions.

Extron Introduces iPad Control App for TouchLink and MediaLink Extron is pleased to introduce Extron Control, a new app that gives users complete access to any Extron control system, directly from their iPad. After a quick initial setup, the iPad connects to the desired room, allowing for complete control. The app automatically loads the user interfaces present on any Extron control product without a lengthy setup and customization process. The familiar interfaces emulate the TouchLink touch panel or MediaLink controllers in your room, as all button presses are kept in sync between the app and your Extron control devices. Extron Control is available for download from the iTunes App Store. Existing users of the TouchLink App will automatically receive Extron Control when they update. Since MediaLink for iPad will be retired, Extron is offering education institutions special pricing on the Control App through the Apple Volume Pricing Program.
Other features include the ability to quickly add rooms and switch between rooms, and auto-reconnect which recalls the previous session even after the app is closed. Technicians will appreciate this new app as it supplements the control of any room and provides easy access for troubleshooting. Extron Control is compatible with projects created in Extron Global Configurator 3.5 or Global Configurator Plus and Professional.

Extron Adds DTP CrossPoint 84 Presentation Matrix Switcher Model Extron’s all-new DTP CrossPoint 84 is a new 8 x 4 switcher with an integrated control processor or amplifier, adding another model to the company’s family of DTP CrossPoint matrix switchers. The 2U (rack-unit) DTP CrossPoint 84 is basically a system hub as it’s an 8×4 matrix switcher with 4K inputs and outputs, includes two built-in independent scalers, integrated DTP and XTP transmitters and receivers and an audio DSP in one package with an integrated control system — not just a port.
The DTP CrossPoint 84 is 4K capable and the DTP twisted pair inputs and outputs provide can handle any input or output signal and send it via CATx cable. The twisted pair inputs and outputs can also be used to connect to any display with an HDBaseT input or tie into a centralized, facility-wide XTP System to add local room-based AV systems.
A high performance scaler is paired to each of the two DTP outputs, so that incoming source signals can be optimized and converted to deliver the highest quality image content for display. With Extron’s exclusive digital technologies, integrators can easily connect sources and displays and set up switching ties, with plug-and-play simplicity, automatic device negotiation, and nearly instantaneous switching delivered with Extron EDID Minder, Key Minder, and SpeedSwitch.
The DTP CrossPoint 84 includes an integrated professional-grade DSP featuring the same Extron 64-bit ProDSP technology in the highly regarded, award-winning DMP 128 digital matrix processors. Integrators can customize system designs and mixes any way desired, with fully configurable EQ, filters, dynamics, extensive matrix mixing options, and so much more. If a large number of microphones or speaker destinations are needed, the DTP CrossPoint 84 offers a unique digital audio expansion port that links the internal DSP to a DMP 128 for additional inputs and outputs, or to add AEC to a conferencing system. For even greater scalability, the DTP CrossPoint 84 can be linked into a DMP 128 on a Dante network for unprecedented system expansion possibilities.

Extron Introduces NetPA Compact Audio Power Amplifiers with Dante Extron’s new NetPA 502 AT and NetPA 1001-70V AT are both half rack 1U, convection cooled power amplifiers equipped with Dante digital audio networking. The NetPA 502 AT delivers two channels of 50 watts into 4 ohms, and the NetPA 1001-70V AT provides a single channel of 100 watts at 70 volts. NetPA amplifiers can receive audio from Dante-equipped audio processors over a standard local area network, greatly simplifying the cabling infrastructure for sharing audio across multiple rooms or floors in a building. In addition to amplifying incoming Dante audio, NetPA amplifiers feature line level outputs that can simultaneously feed an additional speaker zone or audio system. They feature an Extron exclusive, highly efficient, advanced Class D amplifier design, plus patented CDRS — Class D Ripple Suppression that provides improved signal fidelity over conventional Class D amplifiers.
The NetPA 502 AT and NetPA 1001-70V AT are professional grade amplifiers, featuring greater than 90 dB signal-to-noise ratio and less than 0.1 percent THD+N. The amplifiers have recessed, detented level controls located on the rear panel that facilitate adjustment of audio system gain structure, or setting an individual level for each zone. They also have an ultra low inrush current draw to prevent power circuit overload that occurs when multiple amplifiers are switched on simultaneously. This feature eliminates the need for power sequencing in systems with multiple amplifiers in large centralized equipment racks, and prevents other equipment from experiencing power interruption from associated power surges.
A network of Extron Dante-enabled products, including the NetPA amplifiers, can be set up using Dante Controller software as well as DSP Configurator Software. Dante Controller is used to easily assign an output from a Dante-equipped digital signal processor to an input on a NetPA amplifier. Dante-equipped products are AVB — Audio Video Bridging ready.

JBL SRX800 Series models include the 12-inch two-way SRX812P, 15-inch two-way SRX812P, dual 15-inch three-way SRX835P, 18-inch SRX818SP subwoofer and the SRX828SP, the world’s only dual-18-inch powered subwoofer at this price point.
The SRX800 Series utilizes JBL transducers that combine high power handling with extremely low distortion. JBL says the high frequencies are handled by waveguides that provide accurate horizontal and vertical pattern control with smooth frequency response over a wide area. The high-excursion woofers deliver the clear, articulate, powerful bass that is a JBL hallmark, with minimal dynamic compression even during continuous use at high volume. SRX800 loudspeakers and subwoofers are rated at between 135dB and 141dB depending on the model.
All JBL SRX800 models incorporate built-in Crown DriveCore amplifiers with 2,000 watts power output (1,000 watts in the SRX818P). The amplifiers’ on-board DSP includes 20 parametric equalizers, 96kHz FIR (Finite Impulse Response) filters for improved crossover tuning, speaker-delay adjustment and even a signal generator to aid in system calibration. All models also incorporate JBL Application Engineered preset tunings that facilitate fast system setup. In addition, JBL SRX800 Series loudspeakers and subwoofers are fully compatible with HARMAN’s HiQnet network communications protocol, enabling control via Audio Architect or JBL SRX Connect—the new iOS and Android application that provides a fast streamlined approach to system control.
SRX800 Series enclosures are built for extreme durability even under the most demanding applications. The speakers have M10 suspension points for easy rigging and standard 35 mm pole cups for stand mounting. The rear panels feature an LCD screen and glow in the dark ink to facilitate setup even on dark stages. The SRX812P includes feet that enable it to be used as either a main or monitor speaker.

For all you REGULAR readers of rAVe ED [Education] out there, hopefully you enjoyed another opinion-packed issue!
For those of you NEW to rAVe, you just read how we are — we are 100 percent opinionated. We not only report the news and new product stories of the ProAV industry, but we stuff the articles full of our opinions. That may include (but is not limited to) whether or not the product is even worth looking at, challenging the manufacturers on their specifications, calling a marketing-spec bluff and suggesting ways integrators market their products better. But, one thing is for sure, we are NOT a trade publication that gets paid for running editorial or product stories. Traditional trade publications get paid to run product stories — that’s why you see what you see in most of the pubs out there.
