Starin AV Meetup - San FranciscoOn April 26, 2012, Bill Mullin, Forrest Breese, and I hosted the first of many Starin AV Meetups: early evening networking events for audiovisual professionals to get together in a relaxed social setting. The first AV Meetup was a three-hour cruise around the San Francisco Bay sponsored by BenQ, Barco, Revolabs and Wow Vision.  In addition to free food and drinks, and a scenic cruise around SF Bay, the attendees got some valuable hands-on time with some new products.

The AV Meetup turned out to be a huge success for all.  The attendees included a lot of audiovisual consultants and systems integrators who work in education and corporate markets.  Everyone enjoyed seeing the wireless presentation and interactive solutions in person.  I personally demonstrated the Wow Vision ProVEOS and its Connect Me app for PC, Mac, iPad, iPod, and iPhone. It was a great opportunity to have one-on-one discussions about specific applications.

Stephen Spears of Revolabs brought along samples of their wireless microphones, as well as the new FLX conference phone.  The FLX (pronounced “flex”) is a fully wireless conference phone system including wireless speaker, wireless microphones, and wireless dialer.  The popular FLX is now available for VOIP networks, and a four-microphone version is in the works.

Theo Mayer was also on board, giving MeetupPaul Konikowski demonstrates Wow Vision attendees a sneak peek at the new Barco ClickShare wireless presentation tool. And Scott Coffee showed off the new BenQ T420 42″ multi-touch display, perfect for K-12, kiosks, museums, wayfinding, and interactive digital signage. Any applications that needs a large touchscreen combined with a PC.

The next Starin AV Meetup is scheduled for next Tuesday May 8, 2012, a boat cruise in Newport Beach, CA.  See you on board!

2012: The Year Of Wireless AV

But What About Wireless Speakers?

by Paul Konikowski, CTS-D

The CE (Consumer Electronics) and ProAV (Professional Audiovisual) markets have been flooded lately with wireless video solutions, from simple point-to-point wireless HDMI transmitters, to enterprise-level collaboration tools like the new miniVEOS from Wow Vision.  But what about wireless speakers? Even powered loudspeakers still require a line level cable to be pulled from the source to each speaker, right?

Wrong!

Let me introduce you to WiSA™, the Wireless Speaker and Audio Association, an industry group setting a new standard for high-performance wireless speakers.  Traditionally, wireless audio has had a bad reputation, because most wireless audio technology uses the 2.4 GHz spectrum commonly #occupied by other consumer electronics. The result is dropouts and poor audio quality due to the “reduce to fit into 16-bit” compression algorithms needed to compete in such hostile wireless environments.

Conversely, WiSA™ uses spread spectrum technology from Summit Semiconductor in the 5 GHz Unlicensed National Information Infrastructure (U-NII) frequency band.  This avoids interference by other consumer wireless devices.  The result is audiophile-quality, 24-bit surround sound, with virtually no lag.

According to a December 2011 press release, “The Wireless Speaker and Audio (WiSA™) Association was launched … to advance the adoption of wirelessly transmitted high-definition (HD) surround-sound audio in the home theater environment by establishing the industry’s first interoperability specification and certification testing programs for manufacturers of high-performance wireless speakers, DTVs, Blu-ray Disc players, and other consumer electronics (CE) devices.  Aperion Audio, DEI Holdings, Inc. (parent company to Polk® Audio and Definitive Technology), Hansong Electronics Co.Klipsch® Group, Inc.Meiloon Industrial Co.Pioneer CorporationSHARP CorporationSilicon Image and Summit Semiconductor signed Letters of Intent to join the WiSA Association as Advisory Board members to promote interoperability of interference-free, wireless surround-sound audio across a wide range of consumer electronics devices. ”  Sweet.

We all know at least one room that has begged for wireless speakers, let’s start with your own home theater systems.  Even if your living room has been pre-wired for surround sound, is it 5.1, 6.1, or 7.1?  Are the speakers located where you actually want them?  With WiSA™ wireless speaker technology, you are not limited by your speaker wires. If you want to completely reorient the room, and flip it by 180 degrees, you can.  Since the WiSA™ speakers have built-in amplifiers, you will need to plug each speaker into a local power outlet, but that’s typically a lot easier than pulling speaker wires through walls, around the chimney, or under the floor, in the crawl space.

Now let’s put home theater applications aside, and think of some larger applications where WiSA™ wireless speaker technology could be used.  What about a Church that wants to start having a weekly movie night for teens in their sanctuary?  You could have a projector and WiSA™ -enabled surround sound receiver on a portable cart.  Then, just roll down the projection screen, carefully place the WiSA™ speakers around the edges of the room, and plug them into local power outlets.  No need to worry about complicated programming, or teens tripping over the speaker wires, just turn it on and you are good to go.  You could use the same portable setup for a high school gymnasium, or an outdoor movie night.

Or how about that new Executive Breifing Center (EBC) in Silicon Valley, that will have 4 walls made of glass, and no finished ceiling? (I wish I was kidding) Or maybe in that old Ivy League classroom where you are not allowed to touch the ornate ceiling, or the wooden walls, or core the floors?  We have all begged for wireless speakers at some point, and I’m sure we can all think of commercial uses for them.

Yes folks, the year of wireless AV is here; and 7.1 surround sound audio is included.
