On Architectural Samples and Fighting “Scope Leak”
By Leonard Suskin Pixel and Ink-Stained Wretch
I seem to have acquired a spool of glowing glass.
OK, it’s an architectural sample of Corning’s Fibrance light diffusing fiber, and it landed on my desk as an architectural sample of something which intrigued one of the members of the design team on a project I’m working on. What to do with it? That speaks to the shifting role of the AV consultant in particular and of us in the AV industry in general.
The first answer — the “classic” AV answer — is that I can design a system which could interface with and control whatever light engine they devise for it. It’s obviously a purely decorative element which neither processes, transports, controls, nor displays audio or video information. From the point of view of my scope as an AV designer that’s a perfectly reasonable response: “Tell me how you’re using it, and I’ll make sure the system can control it.”
Do you see what I did there? I just showed you how we can give away scope and reinforce the perception that we are narrowly focused specialists with a bit of tunnel-vision for things outside of our specialty. Mark Coxon recently wrote about what he calls “scope leak,” or the tendency of the role of the AV team to shrink as more of what we do becomes commoditized, commercialized or both. I hope you’re in agreement that now is not the time to give away scope or to do the bare minimum. Coxon is right that parts of our role are shrinking. What we need is to find as many ways as we can to leverage our expertise to the benefit of our clients before someone else steps in and answers the questions we should be asking.
If we shouldn’t look at it as mere decoration and outside of our scope, how should we look at something like fibrance? I’d start by looking at it as an interface. Systems can communicate via status lights, touch-panel icons, messages on web pages… and glowing ribbons of glass. So I started to play with it. Wrap it around the back of a monitor to see how visible it is. Around the front of the monitor to see how distracting it is. Across a keyboard. A mouse.
If you get a sample of something, take advantage of having a sample. Explore it.
This is also a big advantage of working at a firm like SMW with other smart and engaged people; we can explore together, ask and answer questions. Some ideas came forward as we explored:
- Placing it across the back of the monitor isn’t very useful; there isn’t enough light to be visible, and there are simpler ways to create that kind of illumination.
- Wrapping the front of a monitor does produce a very visible result without being so bright as to cause eye strain. It does create a very specific aesthetic, which feels 1980s retro-future. It’s a strong look which might be jarring in some settings.
- A single strip along one edge of a device creates a far different look.
- Because it’s a line, it could be used to show interconnects between elements; light up a strand between a video display and associated speakers, for example. Alternatively, like colors could be used to identify which source is connected to which display if you have multiples of both.
- It could be used to outline technology which is otherwise invisible. One could, for example, run a ring around an inductive charging pad flush-mounted to a table.
There’s still been no decision on how, if at all, this is to be used in the project. It might be one of those clever ideas which doesn’t go anywhere or it might be a real opportunity to do something interesting and special. Even if not, it gives me another tool in my toolbox for the next project. It also brings us from the AV world to the larger conversation which takes place outside the wires. That’s a place where we’ll increasingly have to live if we want to add value, and to keep our place at the table. Leave a Comment

Trying New Things Without Disaster
By Lee Distad rAVe Columnist
In the past, I’ve talked about problem solving and how much AV pros love to do it. I also cautioned against being so fond of problem solving that you subconsciously engineer situations where you can swoop into the middle of a crisis and be the hero. After all, as I pointed out, the only thing better than solving problems is not having any problems to begin with.
One potential source of problems comes from including untested products or solutions into the client’s system. Ask any seasoned AV installer or manufacturer’s rep who knows what he’s talking about and they’ll give you one word of advice. That word is “Don’t.” Or more commonly, “DON’T!” And yet, it’ll still happen.
I’m certain that there are numerous scenarios for venturing into Parts Unknown while on the job, but the two most common, or at least the two that I’ve been guilty of are either Unjustified Confidence In Your Vendor and We’ve Never Had To Do That Before.
The first one is the easiest one to place a blanket proscription against. Never, ever, EVER install product that you haven’t already vigorously tested and retested in the office and your showroom’s demonstration system.
I’ve made the mistake of doing unpaid Beta testing for a manufacturer. It sucks. In one instance I boldly specified a brand-new remote control system (the brand shall remain nameless) into a simple media room job. Long story short, the remote and its module were NOT ready for prime time. After thirty total hours of troubleshooting, programming changes, calls to tech support and firmware updates, not to mention getting scolded by my boss we scrapped the remote, and plugged in a proven unit.
In his withering email to the vendor my boss pointed out, “We could have programmed a Crestron system for an entire house in thirty hours!”
Technology continues to advance, and we all need to learn something new on a regular basis. If you wanted to play it safe, you’d all still be installing volume control knobs, and nothing else. The lesson here is educating yourself on your own time in the office, not on the customer’s clock.
The other instance is when you tackle technical hurdles on the jobsite that you’ve never had to deal with before. This strikes most of us while still rookies, but even seasoned professionals have stories about venturing into the unknown.
The one that springs to my mind was being responsible for HVAC control in a palatial house whose HVAC was a hybrid of multiple systems, including both forced air and glycol in-floor pumps. In addition to multiple temperature sensors, multiple thermostats were required and they all had to be controlled via a simple interface.
In instances where you’re venturing into Parts Unknown you need to be honest with your client, and be clear that, “We’re very competent and professional, and that’s why we’re telling you now that we’ve never done something like this before.” You’re way better off getting that out in the open instead of trying to bluff and fake it. In those scenarios, regardless of the standard labor agreement your company uses, the best solution is to work it out with the client so that you bill for the actual time it takes to deliver a finished project.
In the aforementioned hybrid HVAC system, not only did we bill for our actual time designing and making the controls work, we availed ourselves of outside expertise, not only from our vendor, but also from subject matter experts on CEDIA’s teaching staff.
Even if you’ve never been down a particular road before, odds are someone else has. Ask other professionals for their expert advice, and heed it. That support allows you and your team to learn and grow. Leave a Comment

Can Ultra-Slim LCD TV Compete With OLED TV?
By Jimmy Kim DisplaySearch
Ultra-slim has become a main feature for mobile PCs, and TVs are also trying to capitalize on this trend. Recently, Sony officially launched its Bravia X900C and X910C series LCD TVs described as having “ultra-thin floating styles” with only 4.9 mm thickness.
With OLED TV being promoted with under 5.0 mm thickness, a 4.9 mm thickness would be an indispensable specification for ultra-slim LCD TVs to compete in the high-end market. LCD TV thickness has been reduced with the introduction of edge-type LED (E-LED) backlights, which lower LCD module thickness from 30-40 mm to only 10 mm. However, the total thickness of a typical edge-type LCD TV set is still around 30-40 mm. This is mainly due to the modular structure of the LCD TV. The LCD and other components for TV sets are supplied in the form of modules. These require space in the TV set structure for the SMPS, sound board, image processing board, and others electronic components plus the chassis.
However, with the help of the open cell business and BMS (Backlight Module System) business model, TV makers have introduced a single module design to remove the chassis and optimize space configurations in LCD panels and other electronics. With the help of open cell technology, the TV set thickness can be reduced to 10 mm without any additional slimming technology.
Glass LGPs (Light Guide Plate) are being used to further slim TV designs. The current LED thickness for TV is about 3 mm, and the thickness of the LGP should be the same as the LED. However, slimmer LEDs can lead to a decrease in luminance, so the number of LEDs required increases. When glass LGP was introduced, a 1 mm thickness became available. The number of LEDs could be minimized due to the higher transmittance of glass materials.
Sony’s ultra-slim TV (and target thickness for competition with OLED TV) is 4.9 mm. This means that a total of 5 mm must be reduced from the typical 10 mm LCD module. In the below figure, we summarized the component technologies for ultra-slim LCD TVs. 3 mm can be reduced by slimming the optical sheet stack and glass substrate.
Most of the slimming technologies in the above figure have already been adopted in mobile LCDs. The manufacturing cost per unit area is higher for mobile LCDs, but not as much as for large-area LCDs. So the question is how much of a premium will super-slim LCD TV incur? And will this premium be comparable with OLED TV, which is naturally slim because there is no backlight?
In our cost simulation, if we assume a normal 55” 4K LCD module is 1, then the ultra-slim LCD module will be 1.7X. This is still considered to be economical compared with the same specification OLED TV, which would be over 3X that of LCD.
The next question is will consumers pay more for slimness alone? Slim LCD TVs may cost less than OLED TVs, but OLED has several merits beyond just a slim design. Also, consumers see OLED as a totally new technology, while ultra-slim LCD is regarded as just a revised one. Therefore, OLED may be able to justify its premium. Other TV makers should continue to carefully observe the market for now.

Bowers & Wilkins Launches Three New Installation Speakers Bowers & Wilkins announced three additions to its range of custom installation speakers. The new CCM Cinema 7 in-ceiling speaker and CWM Cinema 7 in-wall speaker get their high performance thanks to the application of Bowers & Wilkins core acoustic technologies. While the new CCM632 offers discreet musical fidelity, clever new fixings now make installation quicker and easier than ever before.
CCM Cinema 7 is designed for down-firing, in-ceiling left, centre and right speaker positions in a discreet home cinema system. It boasts two drivers: a 180mm bass/midrange Kevlar cone and a 25mm Nautilus swirl loaded aluminum dome tweeter.
Both drivers are angled to the mounting surface and can be directed towards listeners so they hear the correct balance of sound. That way, dialogue is crystal clear and special effects come across accurately, according to B&W.
CWM Cinema 7 in-wall speaker does the job of three home cinema speakers — front left, center and front right — but is discreet. It can be mounted beside, above or below the screen.
Both Cinema 7 speakers feature ultra-narrow bezels and magnetically attached metal grilles that can be customized. CCM Cinema 7 is supplied with a round grille but this can be replaced with square.
Cinema 7 speakers are installed in the ceiling or wall using Bowers & Wilkins QuickDogs fixings — spring clamps that rotate and clip into place, so you can fit the speaker frames securely, tool-free, with one hand.
The new CCM632 is designed for musical fidelity with the near-invisibility of an in-ceiling speaker. Its full-range 75mm driver claims to solve a common problem with custom install speakers: Small drivers don’t offer enough bass but two-way speakers with a tweeter positioned in front of a bass/midrange driver lead to sound discoloration.
CCM632 is supplied in stereo pairs and comes with both round and square grille/bezel assemblies that attach magnetically. Pricing starts at $250 and range up to $850. The company’s website is here. Leave a Comment

Extron Ships NetPA Compact Audio Power Amplifiers with DanteExtron has announced the availability of the Extron NetPA 502 AT and NetPA 1001‑70V AT, 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 receive audio from Dante-enabled devices over a standard local area network, allowing for decentralized distribution of audio throughout 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 advanced Class D amplifier design, plus patented CDRS – Class D Ripple Suppression that they say 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, such as the Extron DMP 128 AT, to an input on a NetPA amplifier.

Crestron Ships Wireless TST-902 Touch PanelCrestron announced today the release of its TST-902 8.9″ Touch Screen saying that it’s an enterprise-grade wireless tablet. The nine-inch tablet is designed for wireless control and it uses a capacitive touch screen panel and delivers video via H.264 and is integrated into an edge-to-edge glass design.
The TST-902 primarily communicates via Crestron ER instead of Wi-Fi and wireless communication is enabled via the Crestron Extended Range RF Wireless Gateway (CEN-ERFGW-POE) for ultra-dependable wireless performance up to 200 feet indoors.
While the TST-902 can be used to control communications using ER wireless alone, you can use ER and Wi-Fi together (dual-mode) to integrate streaming video from IP cameras or for web browsing.
Crestron says the TST-902 incorporates new fast-charging Lithium ion battery technology that makes it possible to keep the device docked indefinitely without killing the battery. And, to help extend battery life, the Instant-Waking feature allows the TST-902 to go to sleep within seconds of putting it down. But you’ll never have to wait for the screen to wake up — with Instant Waking the TST-902 is always ready to go. If necessary, the TST-902’s battery is field replaceable.

Da-Lite Debuts New 0.8 and UST 0.45 Parallax ScreensBy now, it’s likely that everyone knows that the new Da-Lite Parallax screen is an OEM’d dnp screen, but dnp is known for awesome ambient rejection screens. And, it means that it’s available to everyone in the ProAV market.
Parallax features an advanced optical lens system that rejects light, rather than only diffusing light. This new technology mimics the look of a television, but without the glare from windows or lighting fixtures. And, it can be made in sizes up to a 120 inch diagonal.
Parallax is made up of multiple micro-layers to achieve its light blocking properties and superior viewing angles. Each micro-layer has a function in creating the brightly lit display. Layers that are black boost contrast and absorb ambient light from the sides, while a specially shaped layer blocks light from above. This is evident in demos where lights can be shown directly above the screen without washing out the image.
Parallax 0.8 for standard throw projectors and Parallax UST 0.45 for ultra short-throw projectors. Both products are flexible, shipping in a roll, and feature speckle and glare-free surfaces as well as extremely wide viewing angles of 85″ and 80″ respectively.

Pakedge’s BakPak 3.0 Now ShippingPakedge has introduced the third generation of its BakPak Cloud Management System, which is now available industry-wide after its limited release last month at InfoComm 2015. It is also now shipping with the NP36 network patroller.
The cloud based remote management solution gives integrators end-to-end control from a distance with in-depth monitoring of network devices and control systems. BakPak does this with prioritized alerts, robust permission settings, automated network repair and mapping, easy configuration management, report logging, backup and restore functionality, and TriPlex – a unique troubleshooting system that determines the cause of the problem in case of a network outage or configuration error and suggests potential fixes.
Should BakPak’s built in self-healing features not be able to resolve a network failure, integrators can count on the intuitive alert system.
Pakedge says that unlike other remote management system, BakPak 3.0 does not send misleading alerts – it is intelligent enough to pinpoint which device failure caused the network to crash instead of inundating integrators with a string of “device failure” notifications that don’t help. It does this by validating all error alerts through situational-aware AI algorithms to provide accurate usable information to take action on. These useful alerts are sent via e-mail, SMS, or the BakPak app so the integrator can respond as necessary.
Power scheduling, power cycling and power control on POE switches and PDUs can be managed as groups as well. Even system backups can be grouped – instead of backing up configurations on devices individually, you can backup all the configurations for all the devices across the network at the same time with the click of a button. The configurations are then stored on the cloud for easy device replacement in case of failure. No additional setup or configuration required – simply swap out the affected unit and restore configurations from the cloud.
BakPak’s intelligence is not restricted solely to Pakedge devices. Intelligent device management and third party device integration is a core part of BakPak’s service offering — with greater support for more third party devices being added often. At launch, BakPak 3.0 offers full compatibility and support for Control4, Crestron, Middle Atlantic and Panamax devices. Even for third party devices not natively supported within BakPak’s own interface, users can use BakPak to access the built-in GUI of any third party device on the network, allowing configuration and management from anywhere in the world.
The Pakedge BakPak was designed to save technology integrators time and money by eliminating tedious processes. Automatic device discovery and auto-mapping minimizes setup time and simplifies troubleshooting in case of network problems. Group firmware updates and power control makes maintenance a breeze. Prioritized alerts, automatic self-healing, Triplex automated troubleshooting, and cloud managed backup and recovery help integrators bring peace of mind to their clients.
Pakedge developed BakPak and offers it in three service tiers – Basic, Advanced, and Premier. The company hopes integrators will use as an example for developing managed services as a part of their businesses.
To kick off the launch of the new revamped BakPak 3.0 Pakedge announced that it would be offering the complete suite of features — Premier level services — free until Sept. 30th. After the free trial ends, Pakedge says it will be offering a significant discount on the first year of Advanced or Premier sub-sections. The Basic service model is free and does not require a subscription.

For all you REGULAR readers of rAVe HomeAV 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% opinionated. We not only report the news and new product stories of the high-end HomeAV 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).

A little about me: I graduated from Journalism School at the University of North Carolina at Chapel Hill (where I am adjunct faculty). I’ve been in the AV-industry since 1987 where I started with Extron and eventually moved to AMX. So, I guess I am an industry veteran (although I don’t think I am that old). I have been an opinionated columnist for a number of industry publications and in the late 1990s I started the widely read KNews eNewsletter (the first in the AV market) and also created the model for and was co-founder of AV Avenue – which is now known as InfoComm IQ. rAVe Publications has been around since 2003, when we launched our original newsletter, rAVe ProAV Edition.
