CHAPTER 1: Introduction
Congratulations on purchasing the XAP 800, a highly advanced twelve-by-twelve
digital matrix mixer with Gentner

Distributed Echo Cancellation

, noise
cancellation, and audio processing. It uses an internal macro language and 32 user-
definable presets to quickly adapt to a variety of teleconferencing and sound
reinforcement applications such as distance learning, teletraining, telemedicine,
courtrooms, conference rooms, boardrooms, hotels, and houses of worship.
In its most simple form, the XAP 800 is a mic mixing matrix. As such, all
mic mixing parameters can be customized and any input or combination of inputs
can be routed to any output or combination of outputs, with attenuation
adjustments at each cross point. This allows great flexibility in accommodating a
variety of applications and requirements.
The XAP 800 features numerous functions which greatly enhance its
performance and flexibility. For example, it can gate mics on and off when the
sound within a mic’s acceptance pattern reaches a certain level.
The XAP 800 monitors each mic independently, observing ambient levels and
making decisions based on each mic’s environment. Thus, the input for a mic
located in a highly reverberant part of a conference room is gated, mixed, and
processed to compensate for the changes in that area and reduce echo and noise.
This improves audio quality and decreases the possibility of feedback.
The XAP 800 facilitates local and remote PC setup and diagnostics, logic
outputs, and automatic gated mic operation. Mic inputs can be individually
customized to gate on and off as you want, while automatic gain control keeps the
overall sound level consistent. Eight of the 12 channels can be configured as an
automatic microphone mixer.
Adjustments in routing, level, and other functions can be made through
presets activated through a closure on the rear panel, an RS-232 serial interface,
or a control panel on the expansion bus data channel.
The XAP 800 features eight audio processing blocks, each with 15 filters.
Each filter can be configured as a parametric equalizer, high pass, low pass, CD
horn, high shelving, low shelving, all pass, or crossover. This allows you to tailor
the XAP 800’s audio response to optimize the audio quality and fidelity
characteristics of a wide variety of sound reinforcement systems.
