New AV systems offer sharp images, ‘green’ projection

Sound systems incorporate iPods, amplify presentations

Projector companies are also addressing sound system issues in the classroom and lecture hall with devices that attach to projectors. Epson’s AP-60 Sound Enhancement System, for example, can be installed on ceiling-mounted projectors. The device amplifies sounds coming from the projector with four interconnected speakers and directs the sound toward the audience.

The AP-60 also comes with an infrared pendant microphone for educators and students speaking to a large classroom or lecture hall. The Epson device can connect to almost all projectors’ standard mounting equipment, making the enhancement system ideal for school officials looking for retrofit their classroom technology without spending a fortune on brand-new equipment.

As iPods have become ubiquitous among teenagers and young adults, an Illinois-based company called AmpliVox Sound Systems has found a way to incorporate the popular MP3 player into classroom use.

AmpliVox’s IPOD PA System, which is compatible with almost every iPod model and the iPhone, has a docking station for the Apple devices and is designed to amplify the iPod’s sound. The 30-watt machine is used at about 3,000 schools and college campuses nationwide and is made for audiences of up to 500 people, making it usable for even the largest college lecture halls and rooms of up to 2,500 square feet.

The IPOD PA System, which hit the market six months ago, also features a DVD/CD player, a USB outlet, a wireless microphone, and four-hour rechargeable batteries.

“The only way to describe the iPod phenomenon is ubiquitous,” said Don Ross, CEO of AmpliVox, adding that the IPOD PA System recharges iPods and iPhones when they are plugged into the machine’s docking area. “It’s really become a way … for students to incorporate technology in their homework and class presentations and a whole range of [other assignments] that they get from their teachers and professors. … We’re happy to help [students] find new ways to incorporate their iPods in their education.”
