|A Troubleshooting Roundtable|
By Joel Rollins
Last month, we began talking about the highest form of art when it comes to audiovisual systems: troubleshooting.
In that article, I began to make the point that the use of a logical troubleshooting methodology began in your head, rather than by swapping equipment or blind experimentation. I don’t think many people had an argument with that.
But in order to further the conversation, I decided to involve several experts in the field. One of the great things that 30 years in the business will give you is an excellent Rolodex (and yes, I know many of you are too young to understand what a Rolodex was, so rest assured that at this point I am talking about an electronic card file of email, web and SIP addresses).
So, method of addressing them aside, I gathered three highly experienced industry people to give me their comments on the art of troubleshooting. They are:
Scott Wills, CTS-D, CTS-I, Director of International Member Services, InfoComm International
Scott is the oldest card in that “Rolodex,” to the point where he actually once was listed on a paper card. He spent many years as a service and installation manager, and has since spent years organizing training and teaching for InfoComm, before his present role directing member services for the international portion of our trade association. He’s one of the people I think of when I think of the art of troubleshooting.
Jim Smith, CTS, Partner Consulting Engineer, Polycom, Inc.
Many of you will recognize Jim’s name from your own Rolodex. He’s one of the people I have always gone to for insight into troubleshooting complex videoconferencing systems. I’ve taught alongside him for many years at InfoComm, and many of you will also recognize him as a regular panelist for both my columns and my podcasts.
Neil Willis, RCDD, CTS, President, Hypersign
Neil is the only one of the three who never had a paper card in my contacts file, but caught up fast. He’s the president of Hypersign, who formerly ran a large systems design and installation company. He’s one of those people where it only takes you 10 minutes talking to him to understand how deep his knowledge of this industry is.
So I think I gathered a good team for conference call about the art of troubleshooting, and I began by asking them a number of questions:
First, I thought I would open a broad discussion by asking what the first requirement for accurate, effective troubleshooting would be. I got some great answers:
Scott Wills: “Well, I learned my troubleshooting skills as a technician in the Navy. And I would say that the most fundamental thing about troubleshooting is that you must thoroughly know the system or piece of equipment that you are troubleshooting, and what its normal operation is. Absent that, you can’t have a benchmark for what you are trying to solve. For instance, in the Treasury Department they teach the people who detect forgeries by making them thoroughly familiar, first, with real currency. Then, when they see a forgery they know it. In the same way, if you are responsible for troubleshooting a boardroom system, you must first know its normal state of operation, and then you can recognize an anomaly.”
I then asked Neil Willis, who was driving at the time, to add to Scott’s thoughts.
Neil Willis: “I very much agree with Scott, as my troubleshooting skills were learned in the Air Force. We were taught to look at the output of any electronic system to see if it was normal. If it was not, we were taught to work backwards through the signal chain to locate the issue. With our industry and its systems becoming more logically complex every day, is necessary to have a thorough understanding of a given system and not just its components to troubleshoot it at all. If you don’t have an intimate knowledge of how the components are supposed to function together, you’re done. Years ago, we would look at the system physically, to determine if it was properly interconnected and if there were any termination errors. Today, many of those connections happen in logic, so beyond an understanding of the components we must have an understanding of the system and its programming and how these components have been taught to logically work together. So we have added a logical layer to the physical layer which you also must understand to effectively troubleshoot the system.”
At this point, I asked Jim Smith to jump in, with some understanding on a further issue that happens in system troubleshooting today, namely that systems now exist in disparate spaces, connected in the cloud.
Jim Smith: “From what I have seen, is now necessary to understand both ends of a system which is connected via network, in order to determine the intent of the programming and what correct results are. Simply understanding each gadget in the system as a separate unit is no longer enough, as they may have been program quite differently to interact in a specific way. In other words, understanding intent is as important as understanding the electronics. It is certainly possible for each item to function correctly and yet not to achieve its goal as a system which interacts with other systems. One of the traditional problems with AV troubleshooting is that traditionally the system stops at the wall jack. Today, with cloud-based and remote connections to other things, if you don’t know what’s on the other side of that wall jack you have no way to ascertain what the problem is.”
So, given our limitation for this month’s column, what do we draw from our comments so far?
My take is this: In the old days, I went to the field confident that I understood all of the components, and could figure out which one was not functioning correctly. Today, I need (before I go anywhere, or even log in remotely) to review the system as it was specified and installed, and have an understanding of the systems that interacts with before I can troubleshoot it correctly.
Next month, we will ask our panel (actually, I already have) to contribute some thoughts on how to properly prepare to troubleshoot complex or cloud-based systems.
Stay tuned.Leave a Comment

|Share and Share Alike: What Does the Sharing Economy Mean to AV?|
By Midori Connolly
In one week of tapping away on my smartphone apps, I have ordered a ride to the airport from someone driving nearby, reserved a ski condo for a week from a private owner, found someone to pick up my dry cleaning for $5 and secured a boarding spot for my dog in a nearby home*. I am the uber consumer (yes, pun intended) of the shared economy, where underused assets are shared (access v. ownership), and the transaction is usually facilitated through the use of technology. This form of trade involves a heavy reliance on peer regulation/review and the assets involved are generally expensive to buy, or difficult to access. It is a collaborative process of mutual benefit to both parties that creates efficiency by cutting down on waste. Fueled by the tenets of sustainability, community and collaboration, this model of trade perfectly mirrors the greatest social trends of the current era.
First of all, lest you think it’s a fad, a PricewaterhouseCoopers report suggests that the global revenue from the sharing economy could hit US$335billion by 2025. P2P sharing is already a big business at US$15billion, but when businesses begin to connect through the sharing economy, we should see that number rise significantly. Currently, the sharing economy is largely a function of P2P, but it begs the question, what are the indications for a B2B sharing economy… and, further, the AV industry?
Some of the current trends in the B2B sharing economy easily translate to the AV industry. For instance, think of the hot trend of co-working spaces such as LiquidSpace, where freelancers, home-based business owners, telecommuters and other independent workers can pay an hourly, daily or monthly subscription for office or meeting space. This has been a boon for underused office space while the renter also often enjoys networking and front office services. Imagine how this could translate to AV capabilities. Imagine if the database of clients who had available telepresence, TV studio or other high-end, professional AV application was searchable to a community of users. This could be a powerful and useful exchange.
Labor is another hot area where there is great potential for the AV industry. For example, imagine having the ability to skip a labor broker or temp agency and simply find freelance talent akin to the Elance or experience. What about a marketplace to list projects that require collaboration/partnering?
In the staging business, I frequently searched for open cargo space on semi trucks – generally because of a focus on sustainability, but that is certainly a hallmark of the sharing economy. Platforms such as Cargomatic automate a process that used to take me two hours of calls and emails to find space in local delivery trucks.
How about a popup retail space for an AV demo? Storefront is the Airbnb of retail shops, allowing for daily/weekly rental of unused retail space. Have a 3D printer? Maybe a network of 3D printers becomes small-run manufacturing. The list goes on and on… and it’s a fun one to daydream about!
The implications for the sharing economy are massive. It is estimated that every car-sharing vehicle reduces car ownership by 9-13 vehicles: a revenue loss of at least $270,000 to an average auto manufacturer. What does this mean to an AV company? For stagers, UK startup Showslice is connecting event organizers with similar event needs to share resources. On the one hand, it might be viewed as a threat if you were ousted by another AV company. On the other, it’s potentially an opportunity to keep your equipment working more days without additional labor needs. Overall, the best strategy is always to be armed with more information and prepare for fundamental changes in how your clients source and purchase.

|Listen Ships New IR Solutions|
Listen Technologies has expanded its IR technology offerings with the new LT-84 ListenIR Transmitter-Radiator and LA-141 ListenIR Extended-Radiator, as well as the new iDSP IR Receiver. In creating these new IR solutions, Listen Technologies says its engineers considered all aspects of how the product would be used, focusing on the user experience, ease of dispensing, inventory management and battery management at the venue.
Listen claims the new LT-84 ListenIR Transmitter-Radiator is the only product of its kind that provides complete, gapless coverage in a variety of venue sizes. The LT-84 provides twice the coverage as similar products — one unit covers an area up to 30,000 sq. ft. (2700 sq. m), and it is the first product of its kind to feature delay compensation. It is the only two-channel Transmitter-Radiator with up to four frequencies (2.3 MHz, 2.8 MHz, 3.3 MHz, or 3.8 MHz), eliminating the need to purchase additional transmitter-radiators. Simple to install (with the included mounting hardware and legislative compliance kit), it was designed to blend in with the design of any environment without disrupting a room’s design — in fact, it was developed with input from architects and interior designers. Up to four LA-141 Extended-Radiators can be added to the LT-84 for additional coverage. And, when coupled with iDSP IR Receivers, the experience includes enhanced management and storage tools for venues and exceptional listening for end users.
Listen also expands its iDSP (Intelligent Digital Signal Processing) offerings with a new IR version, joining the previously introduced iDSP RF 72 MHz receivers (LR-4200-072 Intelligent DSP RF Receiver and LR-5200-072 Advanced Intelligent DSP RF Receiver). The iDSP IR receiver features an integrated neck loop/lanyard for end users; streamlined dispensing, collecting and care; and environmentally friendly advanced battery technology.
The iDSP IR Receiver offers precise clarity with 20 dB less hiss than comparable products. The integrated neck loop/lanyard improves the experience for people who have hearing aids and cochlear implants with telecoils. iDSP IR receivers are the smallest of their kind, making them easier for venues to store, charge, and distribute; it also makes it easier for end users to wear and operate. Additionally, iDSP IR receivers use lithium-ion battery technology with battery management (same as a smartphone), eliminating the cost and hassle of traditional AA alkaline batteries.
For venues, the benefits of iDSP IR receivers are obvious. They streamline the care and management process — iDSP IR is easier to care for, store, and distribute than comparable products from other manufacturers. Additionally, since the iDSP IR receiver comes with an integrated neck loop/lanyard (making it compliant with the legislative requirement to provide neck loops for hearing aids with telecoils), the complication and guesswork are taken out of achieving legislative compliance.
There are also benefits for end users: iDSP IR is easier for end users to check out from venues, it’s easier to operate, and it’s easier to wear. Also, iDSP IR receivers can be programmed (using free iDSP software) with unique display names, like Theater, Chapel, Classroom, or more. Additionally, the iDSP software allows venue inventory management and a convenient USB port makes it easy to set up software and apply updates.
System components include:
- charging tray, which can be mounted in several ways
- charging case
- optional cable management system
- earphones (with leatherette cushions, or hard plastic, solving certain sanitary issues)
- log book
- free setup/inventory software and signage
Two headphone jacks accommodate neck loop/lanyard or two sets of headphones (could be shared if needed).

|Sennheiser Launches AVX Wireless Microphone Systems for XLR-Based Video Cameras|
Sennheiser just debuted the AVX wireless microphone systems for video cameras and the receiver plugs directly into the XLR port of a camera, where it automatically pairs with the microphone and switches on when the camera does. The system automatically adjusts the correct audio levels and transmits using a specially protected link in the license-free 1.9 GHz range. Setting up and recording high-quality audio for video has never been faster or more convenient.
Convenience starts with not having to register the system or pay for its use: AVX operates in the license-free 1.9 GHz frequency range, which can be used in many countries worldwide. The convenience continues in operation: the plug-on receiver automatically switches on with the phantom powering of the camera, and automatically pairs with the transmitter. The system immediately sets the correct audio level, perfectly matching it to the camera’s input sensitivity, selects a free frequency – and is ready for the job at hand. If a source of interference appears, AVX will inaudibly shift to a new frequency.
AVX is equipped with adaptive transmitting power, meaning that the system always uses the power that is required to maintain a reliable connection between the microphone and the camera receiver. This not only ensures a stable link, it also reduces battery power consumption — as does the automatic on/off function.
The AVX receiver and transmitter are powered by special lithium-ion batteries, which can be recharged via a USB port. To avoid nasty surprises when filming for a long time, the transmitters display the amount of battery life remaining.
For DSLRs with a jack audio input, the AVX systems include an XLR-3/mini-jack adapter cable and the mounting accessories needed to attach the receiver to the camera hotshoe.
AVX is available in three different sets: with a handheld transmitter (evolution microphone head); with a bodypack transmitter and ME 2 clip-on microphone; and in a special professional version with a bodypack transmitter and an MKE 2 clip-on microphone, the benchmark product for film and TV productions.
For the USA, a special combo pack is issued, which includes both a bodypack and a handheld. The microphone head is an MMD 42, the capsule of Sennheiser’s long-standing MD 42 reporter’s microphone. All system components ‑ plus additional items such as a handheld transmitter with on/off switch -‑ are available separately so that users can put together their own tailor-made AVX systems.
The AVX systems and components will be available in June 2015. Specifics are here.Leave a Comment

Thanks to PreSonus Active Integration technology, the mixers on the AVB system can be set up, and your mixing workflows synchronized, in a single step. All input routing to and from the onstage RM mixer and the AI console mixer at FOH is configured automatically. You simply change the channel source from “analog” to “network” on the channels you want to source from the other mixer.
In addition, the talkback and main L/R mix from FOH are set up as the talkback input and main L/R outputs on the RM mixer onstage. The talkback on/off at FOH also engages the talkback onstage, making it easy to communicate with the band. PreSonus Active Integration also keeps your scene save and recall in sync between the mixers in the system.
Both mixers can be controlled using PreSonus UC Surface touch-control software or VSL-AI and SL-Remote AI for Mac, Windows, and iPad, and all aux mixes can be wirelessly controlled using PreSonus QMix-AI for iPhone / iPod touch. All audio and control data flows over one slender Ethernet cable, so you can shed that heavy, noisy analog copper snake.
The SL-AVB-MIX option card for StudioLive AI Console Mixers is available now for a U.S. retail price of $399.95

|JBL Professional Intros VTX V20-DF Down Fill Adapter|
JBL Professional is introducing its VTX V20-DF Down Fill Adapter, which JBL Pro says makes it easier to cover audiences more accurately, powerfully and economically in terms of VTX V25-II and V20 cabinet counts. The adapter frame is purposefully designed and engineered as an easy attachment of up to six V20 loudspeakers to larger V25 line arrays.
JBL Pro says the V20-DF guarantees precise alignment and optimum line source array coupling of the vertical wavefronts of the V20 and V25 loudspeakers with minimum physical gap when attached, while offering four variable attachment angles (0, 3.5, 7.5 and 11 degrees) between the V20 down fill block and lower V25 enclosure. For added flexibility, the V20-DF can be used as a pullback accessory when deployed as part of the compression suspension systems on VTX V25-II-CS or VTX V25-CS and can also be used with VTX V25-II or V25 enclosures in fixed angle tension suspension mode.
Sonic consistency between the large and small format D2 dual diaphragm, dual voice coil drivers employed in VTX V25 and V20 as well as dedicated OEM factory V5 presets for V20 when used in down fill mode ensure a seamless transition from V25 to V20 in terms of sound quality. The 105-degree nominal horizontal coverage of V20 provides an excellent complement to the 90-degree coverage of V25-II and V20’s ability to achieve higher inter-enclosure angles (up to 12.5 degrees tightly wrapped) provides an effective, visually discrete and economical down fill solution for the short throw portion of a given audience area to be covered.

|Adamson S-Series Makes Debut|
Adamson Systems Engineering introduced the S-Series this week — a new sub-compact line array system consisting of the S10 line array enclosure, S119 subwoofer, Blueprint AV and the E-rack, Adamson’s new unified rack solution.
The S10 is a two-way, full range, sub-compact line array enclosure ideal for mid-size arenas, theaters, churches and dance clubs, as well as outdoor festivals. It is loaded with two newly designed 10” ND10-LM Kevlar Neodymium low frequency drivers and an NH4TA2 1.5” exit high frequency compression driver mounted to a wave shaping sound chamber which produces a slightly curved wavefront with a nominal dispersion pattern of 110° x 10° (H x V). The compact solution – 265/10.4 x 737/29 x 526/207 (mm/in) — weighs in at a mere 27/60 (kg/lbs).
Adamson’s Controlled Summation Technology is a design method that brings the LF drivers as close together as possible, while symmetrically outwardly splaying them, which enables what the company says is an “amazingly clean” overall sonic characteristic for the S10 enclosure. The end result increases usable frequency range while decreasing summation at the crossover point, reducing interference. The LF drivers are also recessed behind the exit of the HF sound chamber, so as to not limit the size and shape. A small amount of delay aligns the lows to the high frequency energy, with some dynamic overlap control in place as well to diminish any remaining noticeable interference.
The S119 subwoofer has a light-weight, long excursion, 19” ND19 Kevlar Neodymium driver with Adamson’s Advanced Cone Architecture and a 5” voice coil for power handling. It is mounted in an “ultra-efficient front-loaded enclosure, designed to reproduce clean, musical low frequency information.”
The cabinets for both the S10 and S119 enclosures are constructed out of marine grade birch plywood, aircraft grade steel and aluminum and feature Speakon NL8 connectors. The S-Series utilizes Adamson’s new SlideLock Rigging System that allows angles to be set prior to lifting, which then fall into place when weight is taken. A stacking pin is also present to maintain proper enclosure angles when ground stacked. The S10 enclosure is also available as the S10i, utilizing a plated rigging system for permanent installation. The S10i’s slimmed down rigging reduces the weight and cost of the enclosure.
The S-Series is designed to be powered by the E-Rack, Adamson’s unified rack solution that interfaces with and powers the S Series as well as the full range of Adamson loudspeaker products. The E-Rack incorporates Lab.gruppen amplification, combined with versatile I/O and industry standard power connections, as well as a 20 port managed Ethernet switch to route dual-redundant Dante and control signal. E-Racks are sold in eight-channel or 12-channel configurations with Lab.gruppen’s PLM 12K44 amplifiers — one 12 channel E-Rack can power up to 24 S10 enclosures. A personal license for Adamson’s Blueprint AV software is included with each E-Rack.
S-Series accessories include the S10 Support Frame, S10 Extended Beam, S10 Underhang (to adapt S10 to fly as an underhang with either the E15 or E12), S10 Dolly, S10 4up Cover and Dolly Stacking Legs (also used to increase or decrease tilt in either the E15 or E12 dolly).

|HARMAN’s JBL Professional Debuts VTX V25-II Loudspeaker|
JBL Professional, a subsidiary of HARMAN, has just announced the VTX V25-II, the successor to the V25 line array loudspeaker. It features a brand-new waveguide for what JBL Pro says is improved long-throw performance, improved wavefront control and improved power matching with the companion Crown I-Tech 4x3500HD four-channel amplifier.
VTX V25-II maintains the same outstanding horizontal coverage performance of the original V25 and current V25 owners can upgrade their cabinets to the new V25-II performance standard in a matter of 10 minutes with the VTX-V25-WG-UK Waveguide Upgrade Kit.
The new V25-II waveguide features design improvements that were motivated by the highly-effective VTX V20 waveguide and differs from its predecessor with revised internal acoustical path geometry and double the number of acoustic transmission paths. In addition, the V25-II waveguide’s exponential geometry assists with wavefront expansion while providing improved wavefront control and line source array coupling in the vertical plane at higher frequencies.
The V25‐II waveguide provides better acoustic loading conditions for JBL’s D2 dual diaphragm, dual voice coil compression drivers, resulting in over 10 dB higher sensitivity above 10 kHz. This sensitivity increase means that less high frequency shelving equalization is required in order to achieve the same acoustic output response and, as a result, there is a significant increase in amplifier headroom. Limiter thresholds can also be adjusted so there is less peak limiting activity and reduced distortion. All of this combines to provide higher maximum SPL and improved system packaging density since there is a better power match when V25‐II is used with Crown Audio I-Tech 4x3500HD four channel amplifiers.
Improved polar characteristics and wavefront control are also obtained with the new waveguide which translate to improvements in long-throw performance and overall, V25-II offers more even coverage, front to back. Improvements can also be found underneath and behind the array, where V25-II focuses significantly less high-frequency energy.
Also new at Prolight & Sound, JBL is introducing the VTX V25-II-CS, which includes the optional V25-CS-K compression suspension kit pre-installed at the factory and is intended for use with VTX V25-VTC Vertical Transporters and accessories.

For all you REGULAR readers of rAVe Rental [and Staging] 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).

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.
Everything we publish is Opt-in — we spam NO ONE! rAVe ProAV Edition is our flagship ePublication with what we believe is a reach of virtually everyone in the ProAV market. rAVe HomeAV Edition, co-published with CEDIA and launched in February 2004, is, by far, the largest ePub in the HomeAV market. We added rAVe Rental [and Staging] in November 2007, rAVe ED [Education] in May 2008 and then rAVe DS [Digital Signage] in January 2009. We added rAVe GHGav [Green, Healthcare & Government AV] in August 2010 and rAVe HOW [House of Worship] in July 2012.
