InfoComm 2009: Acoustics and Audio


Aurora Multimedia’s V-Tune Pro HD reportedly will be valuable to schools and campuses looking for a tuning solution that would broadcast pre-set or spur-of-the-moment announcements or alerts to an entire student body. The V-Tune’s audio is supported by coaxial digital audio and unbalanced RCA connections. Educators can add an optional hard-drive playback feature for digital signage and other various applications for enhancing campus communication, the company says.

Barix audio-over-IP technology supervised audio and control signals over standard IP networks and reportedly is ideal for schools’ digital public address and voice evacuation systems–a centerpiece of a comprehensive campus safety infrastructure. Barix technology lets users route audio to multiple distributed amplifier channels with just a single receiver unit.

Belden introduced the Brilliance Digital Audio Cable line at InfoComm, highlighting the cables’ ruggedness and suitability for a variety of environments, including outdoor school events. The Brilliance line has bare copper conductors and offers an innovative design for an easy-to-install, single-pair audio cable, the company says. This feature reportedly will help school officials reduce setup time for sometimes-difficult-to-use and outdated audio-video equipment.

Technomad featured a variety of weather-proof speakers that could prove useful for school events marred by inclement weather. Technomad’s Schedulon is an automatic MP3 player and recorder complete with an internal clock. The machine is upgradeable and comes with 1,500 minutes of internal audio storage for school announcements.
