AUDIO PERFECTTM AUDIOCONFERENCING SYSTEM
PRODUCT OVERVIEW
The Audio PerfectTM 800 (AP800) provides
the highest possible audio quality available
for conferencing applications. The AP800
contains Distributed Echo CancellationTM
technology, microphone mixing, audio processing and matrix mixing all in a single
one rack unit audioconferencing system.
Simply install and configure the AP800, sit
back, and let one or more AP800 units
handle up to 64 microphones!
The AP800 features acoustic echo cancellation and audio processing on each automatic gating mic or line input. This technology is vastly superior to system-wide
echo cancellation, because it eliminates the
gating and audio processing issues that continually hamper such systems, resulting in
highly reliable, clear, transparent audio for
use in the most demanding environments.
Each of the unit’s eight programmed inputs
and the four auxiliary line inputs can compensate for loud or soft talkers using automatic gain control (AGC). It also offers
channelized equalization for continuous cut
or boost as well as high-pass filtering to
reduce unwanted low frequency noise.
The AP800 provides extreme flexibility for
your applications. Each unit provides eight
processed microphone or line inputs, eight
programmable outputs (programmable
meaning configured with any number of
inputs), four auxiliary line-level inputs and
four auxiliary line-level programmable out-
FEATURES/BENEFITS
puts (for CODECs, Audio PerfectTM 10’s
(AP10 telephone interface), external PAs,
sound reinforcement, VCRs, CD players,
etc.). You get the idea!
For conference applications where you need
significant microphone coverage or multiple
telephone line conferencing, up to eight
AP800 units and 16 AP10 units can be GLinked together using Gentner’s high speed
digital network bus. All G-Linked devices
can be controlled and upgraded via a single
RS232 connection.
Truly linkable—the AP800, via the GLink (high-speed digital bus) allows for
system expansion to accommodate applications requiring up to 64 microphones—all system parameters (gating,
NOM, chairman override, PA adaptive,
etc.) are linked and function as one system
Setup and configuration are simple and
may be accomplished one of two ways: 1)
Using the AP800’s front panel “quick key
setup” and LCD display, or 2) Via
Gentner’s Audio PerfectTM Tools (Windows
95) on a PC. Once presets are customized,
you may access one of the six preset programs on the fly from a remote control
panel (such as AMX or Crestron), a switch,
or the unit’s front panel.
Each of the eight inputs incorporate
Automatic Gain Control (AGC)—
compensates for loud or soft talkers
So relax! The AP800 will handle your
most demanding acoustic environments and
routing configurations!
On-the-fly configuration changes—six
presets, “customizable” programs can be
accessed from a remote control, switch,
or front panel

Programmable matrix outputs—allows
for simple system customization for a
wide variety of applications and individual customer requirements
Easy “plug and play” echo cancellation—easy to design, program, install
and maintain
Full-duplex audio—for conferencing
applications allowing absolutely clear
transparent audio
One rack unit performs the function of
several external audio devices—audio
functions are designed to work together
as a complete audioconferencing system
