Channel Vision makes a wide range of necessary, if not-so-glamorous, solutions for integrators including surveillance systems, structured wiring, multiroom A/V, wallplates, and IR repeaters.

At CEDIA Expo 2013, the company demonstrated how it was breathing new life into some other categories.

First up: A-Bus. Channel Vision has always been a leader in this Cat 5-based multiroom audio technology, but let’s face it A-Bus has lost its sex appeal over the years.

At CEDIA, Channel Vision showed the AB-134, a next-gen class D amplified keypad for A-Bus. It’s 36 percent more efficient than its predecessor and double the power.

While it lacks the power of more traditional multiroom audio systems, “when you do MDUs, apartments and high-rises you don’t need the higher power,” says Channel Vision owner Darrel Hauk.

Also in the A-Bus category, Channel Vision demo’d at CEDIA the AB-315 iBus dock for iPods – a companion to the keypads.

Innovations in Intercoms


Channel Vision also highlighted at CEDIA several new intercom products and features. Most notably, the new TE-AMP amplifier kit adds some oomph to the company’s DP and UI series door intercom systems.

Is that really necessary? I asked.

“It’s a big deal for the guys who use it,” says Hauk, noting that it makes sense for areas with lots of ambient noise such as traffic.

In addition, Channel Vision is coming out with a brand new whole-house intercom system, years after showing the first iteration which was clever in its modularity and Cat 5 architecture but suffered from—how should we say it?—extreme unattractiveness.

Hauk admits as much and waited to launch a new line until the industrial design was right.

The forthcoming Cat 5-based ST-3000 intercom station features capacitive touch control. An onboard proximity sensor triggers the touchpad to light up when someone approaches.

The unit, which integrators with Channel Vision’s DP and IU front door intercoms, has a flat electrostatic speaker on the PC board to make the design sleeker than earlier versions.

The six-zone device can be expanded with ST-3100 station expanders. Up to three of the six-zone units can be connected to an ST-3000 for a total of 24 stations.
