ClearOne AP400 Specifications

Audio Conferencing System
A P 4 0 0
The Audio Perfect ® 400 (AP400) features ClearOne's propri-
etary Distributed Echo Cancellation
enhances the audio quality in any conferencing application
by placing an echo canceller and an audio processor on
every microphone input. This technology is vastly superior to
traditional system-wide echo cancellation because it elimi-
nates gating and audio processing problems that can hamper
such systems. The result is highly reliable, clear audio for use
in demanding acoustical environments.
The AP400 features a built-in telephone interface for
complete phone line integration. The unit also features an
internal power amplifier for easy loudspeaker integration.
The AP400 also performs automatic gating of microphones,
mic mixing, audio processing, and matrix routing – all in a
rack-mountable unit that seamlessly integrates the functions
of each component.
The AP400 provides extreme flexibility for your appli-
cations. Each unit has four mic /line inputs, four line-level
inputs (for codecs, VCRs, CD players, etc.), and eight line
outputs. Every input features automatic gain control to
compensate for loud or soft voices. The mic /line inputs also
offer equalization for continuous cut or boost, as well as high-
pass filtering to reduce unwanted low frequency noise.
For conference applications where you need more
microphone coverage, AP400s and AP800s can be combined

Features and Benefits
• Easy to install – simple to operate.
• Distributed Echo Cancellation technology on each mic/line
input dramatically improves overall system performance,
flexibility, and setup.
• "Plug and play" capability for easy design, programming,
installation and maintenance – no white noise setup.
• Automatic microphone gating reduces background
noise and reverberation, resulting in crystal-clear,
transparent audio.
• Simultaneous two-wire/four-wire capability enables video
and telephone participants to communicate simultaneously
with full-duplex audio.
• Expandable (via the G-Link) to accommodate applications
requiring up to 64 microphones – all system parameters
are linked and function as one system.
• All inputs incorporate automatic gain control to com-
pensate for loud or soft voices, while the four mic/line
inputs offer equalization for continuous cut or boost and
high-pass filtering to reduce unwanted frequency noise.
• Matrix allows for simple routing customization for a wide
variety of applications and individual customer requirements.
• Full system configuration capabilities with advanced
AP-Ware software.
