CHAPTER 1: Introduction

Product Overview

Congratulations on purchasing the Audio Perfect® 400, an advanced eight-by-eight digital matrix mixer with Gentner® Distributed Echo Cancellation®, audio processing, and a single-line telephone hybrid. It uses six 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.

All of the AP400’s functions are programmed in AP-Ware™, an all-new configuration software. The result is quicker setup, with fewer hassles and more control.

In its most simple form, the AP400 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. This allows great flexibility in accommodating a variety of applications and requirements.

The AP400 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 AP400 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 to reduce echo and noise. This improves audio quality and decreases the possibility of feedback.

The AP400 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.

Adjustments in routing, level, and other functions can be made through presets activated through a rear-panel closure or an RS-232 serial interface.

Network-based interconnectivity allows up to eight AP400/AP800 units to be connected and controlled as a single unit.
