Exceptional Voice Quality
With incredibly clear voice quality on both ends of the call, the Norstar Audio Conferencing Unit sounds just like a face-to-face meeting.

• 360-degree Voice Coverage. Three highly sensitive microphones can pick up a voice from any point in a 10' x 15' room. The unit offers the best performance when people are three to six feet from the microphones. But remember: side comments can be picked up from as far away as 25 feet!
• Digitally Tuned Speaker. The unit tunes out echos and background noise and offers a crystal clear sound.
• Full Duplex Technology. Voices can be picked up and heard simultaneously - even interruptions and overlapping dialogue. Conversations sound natural, with no clipped words and no time delays.

Plug and Play
The Norstar Audio Conferencing Unit is compact, lightweight, and easy to move from one room to another. Just plug it in any Norstar digital telephone jack. The Audio Conferencing Unit functions like an M7100 set, with a standard telephone keypad, conference call on/off button, volume control, mute button, and Norstar feature activation key.

Access to Norstar Features
No other audio conferencing system works this flawlessly with your Norstar system. The Feature key makes it easy to use a wide range of Norstar features.
