Too Many Captain Kirks, Not Enough Scottys
By Dr. Frederick Ampel President & Principal, Technology Visions Analytics
For well more than a century, the audio world was warm, straightforward and essentially analog at its core. It was a copper-based universe of wire, resistors, capacitors, transformers, vacuum tubes, transistors and electronic parts you could touch, feel, see and identify easily.
And then, as things are wont to do, it all changed. Individual circuit components combined and merged onto rectangles of silicon substrate and became ‘integrated circuits,’ and ‘chips’ and surface-mount, micro-miniature resistors and other circuit elements became tiny little dots on multi-layer complex circuit boards, unknowable and un-repairable.
Let’s look at two very well known mixing consoles as examples of this evolution.
First we have one of the classics of the analog age, the MIDAS Heritage series. Every knob, switch, button, fader and control has a specific known function and resultant action.
Its evolutionary successor is the MIDAS pro X CC series of DIGITAL mixing consoles, wherein menus, multi-purpose control surfaces, assignable control and all the other advancements of the new generation are in full flourish.
If you just arrived on this planet from another space time continuum, which device would seem more obvious in its functionality and operation — wait, think about it dispassionately.
In this new, all-digital, all-the-time world we now can be greeted by an on-screen message like this:
Because as everything is, at its core, some form of computer, everything is also based on software. Once upon a time, audio was knowable; pathways, gain structure, processing systems and devices and all the rest were at their worst obvious functional blocks. Now we have a code-based world and hardware today runs on software and software requires fairly constant updating for minor issues.
It’s not a choice anymore whether to update or upgrade hardware, because the software that runs it WILL require updates or in some cases wholesale platform shifts or complete revamping of the foundational operating system (OS), whether you want to or not.
Think about it for a few thousand milliseconds (milliseconds are centuries in software land after all); let’s look at the world’s most ubiquitous operating system as an example. In just slightly over three decades we have gone from Windows 1 to Windows 10, but wait! There were so many, many, many steps in between (click the image to see the full resolution table):
This massive list does not even consider the CPU architecture changes required in many cases to even run the OS in question. Every one of these imposed and often un-wanted “updates” supposedly provided improvements, but as it rapidly became more and more complex, this software often became unstable and incompatible with other devices and also caused the long, long list of problems now all-too-familiar to anyone using it. How many hours have you or your company spent transitioning from one version to another? And then add in the multiples of that time you spent getting your clients’ systems to live in the OS’s brave new world. I’ll bet it cam be measured in man-years at a minimum.
Or as the often too realistic Dilbert comic strip so succinctly put it:
It frequently seems as if the folks in software land are using a developmental methodology that often approaches prayer, and products get released, knowingly, that have this idea at their center:
How many times has an algorithm or piece of easily hackable code brought a whole system down because it was badly written, poorly tested (if it was tested at all) and never checked to see if it caused more problems than it fixed.
Part of the problem here is that there are too many people at the top of the organizations responsible for our software based digital world, not enough people actually doing the hard work of making sure the stuff actually works. Scott Adams often skewers this in his Dilbert strips, but the reality is he’s not just being clever or funny: He’s just pointing out a serious and growing problem.
And I haven’t even started on the stuff living on top of the OS. (By the way, although many acolytes would dispute this, the once safe and sound world of Apple OS is no longer immune to these issues, witnessed by the many issues that have arisen in the last few releases and the hacks that followed. And please don’t barrage me with Linux ‘miracles’ — that’s not the point here.)
THE DSP CONUNDRUM
What is the point of this cautionary saga, you might ask? It’s this: Every “block” in a current generation sound system or video system is packed to the gills with DSP capabilities, often totally proprietary, running on customized code and software, isolated from any other block by that design choice. Yet we as integrators designers, consultants and users are supposed to find a way to make all these separate little feudal kingdoms of high-powered silicon work harmoniously and function seamlessly essentially on our own?
Leaving out of this debate the numerous and often complex network backbone issues and digital audio transport complexities (which require their own discussions), we are still faced with a very steep hierarchy mountain to climb.
Let’s look at a typical sound reinforcement system component map. Working backwards from the end point loudspeakers we have:
- Loudspeaker DSP (on board or controller based)
- Amplifier DSP (external or on-board the loudspeakers)
- Network Distribution (with DSP)
- Audio Management/Transport (with DSP)
- Mixing console (with DSP per channel and master/matrix/buss)
At a minimum in most cases, we have at least five DSP blocks and theoretically perhaps even twice that depending on the hardware chosen and its functionality. In the networked sound system world, each of these ‘blocks’ may have an IP address (or multiple IP addresses) and a large number of I/O paths, which also might have some level of DSP built in.
Structurally, which block is in charge and which are following? It might seem obvious, but from the multiple DSP’s perspectives, it’s not — because any or all of these fully-functional, highly-capable processing points is potentially capable of being either a Captain Kirk or a Scotty.
If this ‘who’s in charge issue?’ is not designed in and resolved before anything is installed or configured, you are creating a witches’ brew of bubbling conflict and operational disaster.
If you and your clients/users/operators don’t know where a particular task is being implemented or how it interfaces with the many other things going on simultaneously, it can and frankly WILL create a substantial functional choke point and significant confusion. Is the System EQ being done in the loudspeaker processing EQ, the amplifier EQ or somewhere else? Is it accessible or locked down, password-protected and safe? Is the routing and distribution matrix handling conflict resolution on the network, or is that being done by some other device (a switch for example)?
And… what about the accumulating pass-through delay from each successive layer of DSP and A to D or D to A? Are you aware of how many D/A and A/D conversions are taking place? This creates an incredtible time lag, not to mention the potential signal degradation and data loss that can occur at each step. Oh, and by the way, are all of these steps happening at the same bit rate, word length and bit depth? Do you know? Does anyone know? Has anyone mapped this out? In advance?
Is this beginning to look like a minefield to which you do not have a map? It should, because it is. If all the math and calculations on delay are not factored into the planning and design of a system, you can very quickly find yourself with a substantial delay problem, enough to make it a problem for anyone, professional or not, who has to use the sound system. And this kind of problem is subtle, often hard to quickly pin down and even harder to fix once the system architecture is in place and connected.
Do you know how to determine what device is producing how much signal delay and how to minimize it? Don’t forget, most DSP-based products have a baseline signal delay even if they are not actively processing audio. Unless you have hard-wired full signal bypasses built in around those devices’ DSP sections, you are accumulating delay whether you recognize it or not. Just setting a DSP section or function to bypass does not automatically guarantee that the signal is not passing from beginning to end of that particular block and thus gathering delay as it moves on through.
Sure, all that signal processing power is a major adrenaline hit and can be used very effectively to do magical things. But it all comes with potentially negative side effects (that are often not very visible or audible) — problems that arise on top of the desired results.
So a word of caution is in order. Be sure you know IN ADVANCE how the system architecture will affect the audio or video signal as it makes its way from input to output, multiple times. Be aware of often not-well-documented time/delay accumulations when multiple DSPs are in the system. Be sure you have disabled or bypassed in a solid and difficult-to-change manner any functionality that you don’t want or don’t need. It is inevitable that with many DSPs at play, overlap and duplicate capability is present. It is essential to ensure you have taken this into consideration and carefully and logically decided, recorded, mapped out and documented in writing who is Captain Kirk and who is Scotty.

What AV Integrators Should Know About WannaCrypt
By Sara Abrons rAVe Editor
Last week, a group of hackers released a nasty piece of ransomware that quickly spread across the world, touching anything and everything connected to a network. Deemed WannaCrypt (or WannaCry), the ransomware infected thousands (approximately 200,000, according to NBC) of computers in thousands of countries and in particular wreaking havoc in Europe, where many medical institutions — including the UK’s National Health Service, schools, government institutions and businesses were essentially shut down. One AV/IT victim was Deutsche Bahn, German’s state railway operator, which had a digital signage network alerting passengers to train schedules that went down.
Once inside a system, all user files became encrypted and inaccessible to the owner, essentially held hostage, hence the term ransomware. To get the files back unencrypted, a user has to send $300 worth of bitcoin (an untraceable digital currency) to a certain account within three days. After three days the price doubles to $600. On the seventh day, all the files are deleted forever. The list of file types the code could encrypt was extensive, but included .doc files and most media files types such as .mov and .jpg (you can see the list here), so it would cripple most users who became infected. Pretty nasty, huh?
Fortunately, the spread of the attack was halted when a British cybersecurity researcher registered a domain he found hidden in the code in order to track the attack. The registration actually stopped the spread of the malware altogether, since it relied on connecting back to the domain and receiving no response in order to encrypt the files. If you’re interested in learning more about how the attack was stopped in such a seemingly simple way (it’s not), read the blog by the 22-year-old engineer, known primarily by his online handle MalwareTech, who unknowingly halted the spread. This was an extremely lucky break for everyone (except the purveyors of WannaCrypt, of course).
One of the reasons this attack spread so much further than other Ransomware attacks was because it took advantage of two exploits in systems running Windows that allowed remote attacks and remote control — codenamed “EternalBlue” and “DoublePulsar” respectively. Most ransomware attacks rely solely on phishing techniques, such as getting a user to click a link, in order to infect a computer. These vulnerabilities were identified earlier this year and on March 14th, Microsoft released a patch that fixed the vulnerability.
The threat isn’t over, however — the ransomware could reemerge at any time with a few alterations and any system without the patch would be vulnerable.
What You Should Do Immediately
- Run any and all security updates, if you haven’t already, on all computers, phones and everything you have connected to the Internet for your company. Windows computers running Windows XP, Windows 8 or Windows Server 2003 are extremely vulnerable and need to be updated immediately. More information on how to protect systems using Windows, including a link to the security update that should be installed, can be found here. Microsoft says Windows 10 was not vulnerable to the attack.
- Call your clients and make sure they have done the same, especially if you know they are running systems that use Windows at all.
- Consider offering to come to clients’ businesses and run software and firmware updates on all equipment (you can charge for this service!). How many pieces of AV equipment are floating around out there that don’t have the latest firmware?
What You Should Do After That to Protect Yourself and Your Clients
- Install security updates regularly to all systems. This includes not just software updates, but also firmware updates. If you don’t want to make them automatic, then you should be checking for updates and completing the installs regularly. Out of date devices are a huge vulnerability.
- Train staff and clients regularly in how to recognize phishing attempts. Phishing attempts have become more sophisticated of late and tricking even Internet savvy users. Earlier in May, a convincing email that looked like an invitation to see a shared Google doc made the rounds, and it wasn’t just grandmas who clicked the links and got infected. Regular training is key.
- Use strong spam filters to stop employees from ever even seeing phishing attempts. Use firewalls and anti-virus software.
- Back up files regularly, both to the cloud and locally to another hard drive.
- Have a prepared worst-case-scenario recovery plan in place in the event that something in your network does become infected.
- Whenever possible, at your own company or in designing systems, consider using operating systems other than Windows, which has consistently been the most vulnerable to attacks.
Here’s some additional info on steps businesses can take to protect themselves. Much of what I’ve described probably sounds obvious, but without a protocol in place to do these things regularly, they easily fall by the wayside, even to the large businesses. Just ask the U.K.’s National Health Service or Russia’s Interior Ministry. Now is as good a time as any to review procedures and put a plan in place.
Stefan Baur, project lead of open source project X2Go and owner of BAUR-ITCS (website in German, but English speakers can contact the company through a form), a company offering X2Go support and an X2Go-based security software, gave some additional advice for systems designers and network operators:
- Don’t run Windows when/where you don’t have to. Depending on your area of work, there will probably be some apps that are only available for Windows. That doesn’t mean you have to use Windows for everything else as well, though. Solutions are available that allow you to display single Windows applications coming from a remote server on the screen of a Linux or macOS machine (Citrix, etc.), as well as for the other direction: Displaying a remote Linux application on a Windows or macOS screen (this is what X2Go [and others] does/do).
- Don’t go all Linux, either — diversity is the key. Run some macOS systems here, some FreeBSD there… whatever does the job best. This minimizes the chance that you’ll experience a total meltdown due to an exploit hitting you, as they are usually operating-system- or application-specific (think Microsoft Office).
- Keep systems that require different levels of security (customer/patient data, company data/intellectual property, internet) on separate networks. With the current attack, the pictures spreading on Twitter hint at Deutsche Bahn (Germany’s largest railway operator and infrastructure owner) having placed those infoscreens on their production network and joined to their regular Windows Domain (though we have no solid proof for that yet) — and from a security standpoint, that’s one of the biggest mistakes you can make, and an easily avoidable and totally unneccessary risk to take.
- When I say “separate networks,” I mean it. Don’t even use VLANs. Use separate switching and routing hardware. VLANs are a valuable tool when you have to manage large networks, but they are not a security measure. Yes, more hardware means higher expenses, but everything else will come back to bite you in the long run.
These suggestions supplement the usual security measures, like locking down and hardening systems, regular backups, patch deployment, etc. — they are not meant for being able to safely neglect basic security measures, nor will they work for that. If you want to experience what placing a nice tall building on unsafe ground looks like, book your next vacation to Pisa, Italy — don’t try it out on your company network.
Unfortunately for those infected by WannaCrypt, no one has figured out to decrypt files yet, and security experts are scrambling to get systems back up and running. The only solution is to completely wipe infected systems and restore from an offline backup.

Display Summit 2017: Expanded Focus and New Date – rAVe to SponsorInsight Media, the organizers of the annual Display Summit conference, announced today that the event will now expand its focus and move the date one week further out to October 4-5, 2017. The location remains the same; the Rockwell Collins facility in Sterling, Va.
“The expanded focus is best described as Immersive Displays,” noted Chris Chinnock, founder of Insight Media. “That means projection-based solutions for simulation, training, visualization and entertainment on flat, curved and domed screens as well as body-worn immersive systems such as augmented, virtual and mixed reality systems. This includes commercial, military and professional applications.”
Many of the projection-based solutions are multi-projector so the event will profile advancements in resolution, blending and warping, solid state light sources and more. But the event will also look at competitive solutions that are beginning to emerge for these markets including LCD and LED video wall technology. And just as importantly, related technologies and products from other application areas in ProAV and cinema are important to include in the program.
For body-worn immersive solutions, the focus will be on the hardware solutions along with emerging professional and commercial applications for augmented, virtual and mixed reality applications. But here again, the event will draw upon the full range of applications so attendees can get a broader understanding of the status and future of these technologies.
The event is also likely to feature a session on light field display and capture and its emerging use in a number of applications. In addition, CPU, GPU and other hardware solutions for generating the large images for these immersive solutions will be explored along with the future of physical connections between sources and displays.
“I have been consistently told by previous attendees at Display Summit events that the value is the exposure to a broad range of relevant, but lateral technologies and solutions to the person’s primary area of focus,” continued Chinnock. “That, along with the networking and business development opportunities are why we are now in our 16th year of this event.”
rAVe is the media sponsor of the Display Summit. rAVe Founder Gary Kayye says, “Chris is a display genius — no one is more knowledgable than him and this is a must-attend if you need to keep up with the future of displays.”
Industry experts are invited to submit an abstract to deliver a PowerPoint presentation at the event. There will also be an exhibit area. For more information, go here. Leave a Comment

Earthworks Ships CTB30 Boundary Microphone Earthworks is now shipping the CTB30 boundary microphone designed for conferencing and speech applications. The CTB30 delivers speech intelligibility and coverage coupled with a low profile appearance for conference rooms, boardrooms, classrooms, lecterns and houses of worship.
Optimized for speech, Earthworks says the CTB30 features a flat frequency response from 60Hz to 30kHz and an incredibly fast diaphragm settling time that allows more subtle details of the human voice to be reproduced. Its True Semisphere polar response provides an omni semisphere of coverage and delivers the same high intelligibility of each orator speaking around the microphone without loss of high frequencies. The wide and even coverage across the microphone’s pickup pattern means that just one CTB30 can provide excellent coverage for a 12 foot conference table that seats up to 12 people.
Incorporated into the microphone’s design is a specially engineered filter to significantly minimize the unwanted noises of table thumping, paper shuffling and HVAC. The CTB30 also includes RF shielding to prevent interference from cell phones and other electronic devices.
Measuring just 4.1 inches in diameter, the CTB30 provides a very low profile miking solution and is available in black, white, silver or Nextel Dark Black finishes. The CTB30 comes with a 10-foot (3.04-meter) low profile cable with XLR-3M attached, and is designed to exit from the side or bottom of the microphone. The XLR can be removed, allowing the cable to run through a small hole in the table surface for a permanent installation. Two 6-32 screw holes and a keyhole are found on the bottom of the microphone for secure mounting, allowing a more permanent installation option if required.

Barco’s New AudioCue Solution Aimed at Training Systems and Simulation Environments Barco has a new audio system for simulation. The AudioCue is a solution that adds high-quality and precise audio cues to simulation systems. Barco says the precise audio cues allow trainees to pinpoint objects and occurrences before they are within visual range, greatly contributing to faster decision-making and a trained, educated reaction pattern when a situation is at its most critical state. The result is a system that increases the awareness and effectiveness of training, better answering the needs of a wide variety of training and simulation markets, including ground training (rescue, security, direct combat, etc.), urban, JTAC and healthcare.
Barco AudioCue uses the patented IOSONO CORE processing system for rendering real-time sound in the simulation market. Depending on an object’s virtual location, Barco AudioCue renders sound on the spot, instead of mixing and delivering to a specified channel. This generates audio cues from the exact location that the object should be relative to the trainee’s position. Conventional channel-based systems don’t offer this precision, making the training programs rigid and far less realistic.
The Barco AudioCue processor supports speaker arrangements from eight to 128 audio channels − customized to any room, shape or other constraint — so that the sound rendering is based on the exact position of the speakers and not on a pre-defined layout. Therefore, there is no auditory ‘sweet spot’ in the system, which eliminates the risk of negative training.

Extron Ships 60-Watt ENERGY STAR Qualified Mini Power Amplifier Extron is already shipping their MPA 601, an ENERGY STAR qualified mono audio amplifier spec’d at 60 watts rms output. Housed in a compact convection cooled and UL 2043 plenum enclosure, it meets UL requirements for in-ceiling installations. The MPA 601 employs a Class D amplifier design featuring their patented CDRS — Class D Ripple Suppression technology which they say provides a smooth audio waveform and an improvement in signal fidelity over conventional Class D amplifiers. Three stereo inputs are individually buffered so three separate sources can be connected simultaneously. The MPA 601 meets ENERGY STAR qualification requirements with an auto power-down feature, placing the amplifier in standby after 25 minutes of inactivity. For sensitive applications that require uninterrupted operation, the standby timer can be disabled. The MPA 601 is designed for applications with space restrictions that require sufficient power for a small to medium distributed audio system.
The MPA 601 is available in 70 volt and 100 volt models. With “professional grade” signal-to-noise of greater than 90 dB and ultra-low noise of less than 0.1 percent THD+N, the MPA 601 is ideal for use in applications where fidelity is critical. The compact 1U high, quarter-rack unit can be mounted in a small rack, within a credenza, within a lectern, or behind a display in lobby or commons locations. With a UL rating for use in plenum air spaces, it also allows for concealed installation above a drop ceiling to prevent theft while providing convenient placement of AV equipment.

FSR Expands HDBaseT Line FSR has expanded its range of HDBaseT solutions with a selection of 5Play transmitters. FSR will demonstrate all the new features at InfoComm 2017 in Booth 3843.
HD-HPCUWP-Tx 100 Meter HDBaseT HDMI, PC, USB, Wall Plate Transmitter: FSR’s new HDBaseT two-gang Decora style wall plate, based on HDBaseT 2.0 technology, is a true HDBaseT 5Play device that transmits HD Video (up to 4K@60Hz 4:2:0), audio, bi-directional control (IR and RS232), Ethernet, two-way USB 2.0, and power via a single Cat6a cable out to 100 meters. The front of the wall plate features an HDMI-in and VGA video-in (HD-15 Female) with audio-in (1/8” Mini Jack), analog audio-in (1/8” Mini Jack) an IR reader window, as well as input selector and display buttons to select inputs and control the display/projector via RS232 or CEC control. The HD-HPCUWP-Tx is designed to work with FSR’s HD-HU-SP-Rx 100-meter HDBaseT 2.0 HDMI & USB Receiver model and receives its power from it as well. It can work with any of FSR’s other 100m receivers, but must be used with FSR’s HDBaseT 2.0 USB compatible receivers to fully utilize the USB functions. The rear of the wall plate contains an HDBaseT RJ-45 port as well as captive screw terminals for +12v in for applications where the wall plate can be powered locally instead of via the HDBaseT Receiver.
HD-HU-SP-Tx and HD-HU-SP-Rx 100 Meter HDBaseT HDMI & USB Transmitter and Receiver: Based on HDBaseT 2.0 technology, the HD-HU-SP-Tx and HD-HU-SP-Rx are true HDBaseT 5Play devices that transmit HD video (up to 4K@60Hz 4:2:0), audio, bi-directional control (IR and RS232), Ethernet, two-way USB 2.0 and bi-directional power via one Cat6a shielded cable out to 100 meters. Installers can select USB host or device settings on both the TX and RX and the units can be powered from either end as well. There is also a separate unbalanced analog audio input on the TX unit and an analog audio output on the RX unit. This audio signal travels on its own dedicated channel of the HDBaseT signal separate from the HDMI embedded audio signal. The HD-HU-SP-Tx and HD-HU-SP-Rx provide solutions where users may want to have USB 2.0 access to control PC sources via KVM, or work with interactive displays, media servers or data storage devices.
HD-HSC-SP-Rx 100 Meter HDBaseT HDMI Scaler Receiver: The HD-HSC-SP-Rx is also a true HDBaseT 5-Play device that receives HD Video (up to 4K@60Hz 4:2:0), audio, bi-directional control (IR and RS232) and Ethernet via one Cat6a shielded cable out to 100 meters. The built-in scaler is HDMI 2.0/HDCP 2.2 compliant and can be remotely controlled via API. The HDMI out has built-in CEC Control and the HD-HSC-SP-Rx can be set to automatically send out CEC or RS232 commands to turn on the display when it detects an input signal. There is a de-embedded balanced audio output as well as two Ethernet ports which also allow Telnet control of the device. The HD-HSC-SP-Rx does need to be powered locally but it can remotely power any of FSR’s other 100-meter HDBaseT wall plate transmitters or non-scaling transmitters via the Cat6a shielded cable.

Draper’s New TecVision Grey Surface Projection Screen Tackles Ambient LightDraper’s new TecVision CH1200X ALR is a grey surface designed specifically to address ambient light rejection (ALR) applications. With an ALR rating of 20, the Draper says its TecVision CH1200X ALR rejects 80 percent of the ambient light not being produced by the projector. Designed for environments with high ambient lighting and controlled viewing angles, the CH1200X ALR is a high-contrast surface helping black retention and includes a 1.2 gain surface to help brighten the image in sizes up to 67 feet wide.
Like the rest of Draper’s TecVision line, CH1200X ALR is 8K-ready and Imaging Science Foundation-certified for color accuracy, so users won’t notice the blue tints present in images on many other ambient light rejecting screens. In addition, the CH1200X ALR is available as a Nanoperf surface for acoustical transparency.
Claiming better off-axis performance than its competitors, TecVision integrates a light-absorbing dark backing to prevent picture degradation from light behind the screen and a non-perforated surface.

Barco Adds to LED Lineup With 7 mm Pixel Pitch Version Barco has just added a 7 mm pixel pitch model to its range of ‘digital media canvases.’ The R-series has a thin, lightweight and bendable design and is aimed at uses like retail, advertising, large venue and visitor attraction applications.
Installation and maintenance are key cost drivers for store façades, museums, theaters, houses of worship, stadiums, and corporate or event venues. Up to 75 percent lighter, Barca says the R-series is much easier and faster to install than traditional LED displays, which minimizes installation cost. Offered in sheets up to 4.68 meters long and only 5 mm thick (including louvers), the digital media canvases can cover all kinds of surfaces. And to remove today’s cable clutter, cabling, control, and power electronics are fully integrated on every sheet. Moreover, the power supply unit can be located remotely for easy servicing.
Thanks to their unique bendable, ultra-thin design, architectural constraints are reduced and less space needs to be freed up. And with minimal need for a supporting structure, the R-series can be glued onto a surface or wrapped around curved shapes. Plus, there are no visual segmentations or gaps, as is the case with standard tiled LED displays.
Driven by Barco’s Infinipix image processing platform, the R-series is a future-proof design that includes a web-based interface that enables display configuration, control, monitoring, and maintenance from any device. Based on HTML5, different operating systems and mobile devices can be used to control the R-series, both on-site and off-site. The system supports SNMP to export monitoring data, but sends automatic failure alerts and status notifications as well to minimize operational risk.

New Prysm Go Is Designed to Turn All Meeting Rooms Into a Collaboration Room Prysm today announced Prysm Go, a new product that turns any meeting room into a collaboration room. For meeting rooms that are already enabled with video conferencing codecs such as those from Cisco, Polycom and Logitech, Prysm Go enables meeting participants to accept or reject incoming calls, control meeting room volume, share content with other participants, and dial another video codec-enabled room. This means advanced video collaboration rooms can share content while eliminating the need for separate remotes and complicated, one-off dial-pads.
Other Prysm Go features include:
- Digital whiteboard: Write down ideas, draw diagrams and share whiteboard content via email quickly
- Wired and wireless screen sharing: Multiple participants can share their laptops or mobile-device screens via HDMI, Apple AirPlay or Google Cast.
- Integration with video conferencing and unified communications tools: For meeting rooms that are already enabled with video conferencing codecs such as those from Cisco, Polycom and Logitech, or for users of users of Skype for Business, beginning in early Q3 2017, Prysm Go is expected to enable meeting participants to accept or reject incoming calls, control meeting room volume, share content with other participants, and dial another video codec-enabled room, all from the Prysm display.
- Video integration: Connect live video, audio or data feeds for always-available access to key people and information.
With Prysm Go, no sign-in is required, including access to the digital sketchboard, sharing devices – both wired and wireless, and integrating HDMI outputs. In addition, Prysm Go integrates with Skype for Business and video conferencing platforms, allowing users to join scheduled meetings with an invitation from the host.
Prysm Go is available in two versions. For use with existing displays and hardware, the first version includes the Prysm X30 appliance and a free trial of Prysm Application Suite license, allowing companies to use their existing displays and third-party meeting set-ups whether they are interactive or keyboard- and mouse-driven displays. The second version is for those in need of a display and offers an 85” display Collaboration Board system with the Prysm X30, 85” 4K LCD display and a free trial of the Prysm Application Suite license.
Built on a hardware-agnostic platform, Prysm Go allows for instant meeting start capabilities while also offering an upgradable path to the full Prysm digital workplace platform without additional infrastructure requirements. Companies now have the flexibility to grow with the complete Prysm solution at a user-personalized scale, which supports individual participant content repositories and project persistence. Once the solution is deployed, enterprises can purchase individual licenses with no extra hardware or added implementation required.

For all you REGULAR readers of rAVe ProAV Edition 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. We are different: We run what we want to run and NO ONE is going to pay us to write anything good (or bad).
