ClearOne / Audio Conferencing System, 4 channels automixr/echo cancelling/gating system w/soft

Model Details

Extreme flexibility for your applications
The AP400 Audio Conferencing System features Gentner® Distributed Echo Cancellation® for clean, full-duplex audio with no echo. It features four mic/line inputs, four line-level inputs (for codecs, VCRs, CD players, etc.), and eight line outputs. Every input incorporates automatic gain control to compensate for loud or soft voices.

Built-In Telephone Interface
A built-in telephone interface adds a phone line for teleconferencing capabilities and an internal power amplifier provides easy loudspeaker integration.

Automatic Gating of Microphones
The AP400 performs automatic gating of microphones, mic mixing, audio processing, and matrix routing—all in a single rack space unit that seamlessly integrates the functions of each component. All features and functions of the AP400 are easily configured with advanced AP-Ware™ software. The AP400 is also compatible with the AP800.

Easy to install, simple to operate
Gentner Distributed Echo Cancellation technology on each mic/line input dramatically improves overall system performance
The four mic/line inputs offer equalization for continuous cut or boost and high-pass filtering to reduce unwanted frequency noise
Automatic mic gating reduces background noise and reverberation
Simultaneous two-wire/four-wire capability enables simultaneous audio (phone) and video (ISDN) conferencing
ClearOne's digital signal processing technology ensures clear audio with the deepest, most reliable hybrid null
Selectable auto-answer and auto-disconnect enables integrators to choose auto-disconnect without auto-answer
Expandable (via the G-Link) up to eight AP units and up to 64 mics
Easy system configuration with advanced AP-Ware software
Optional remote control
