CHAPTER 1: Introduction

Congratulations on purchasing the Audio Perfect® telephone interface. The AP10 uses advanced digital technology to maintain the highest possible audio quality. The AP10 is designed as an accessory to the AP800 (echo cancelling, audio processing, microphone mixing matrix) and enables the AP800 to connect to a standard telephone line.

The AP10 is a single-line digital hybrid which uses digital signal processing (DSP) to separate the transmit and receive audio—eliminating distortion, weak signals, and feedback. It continually filters low and high frequency noise to provide pure sound.

Features

•Easy to install and operate

•DTMF dialing capability

•Simultaneous two-wire/four-wire operation within an Audio Perfect system

•G-Link network interconnection with up to eight AP800s and 16 AP10s

•9.6kHz sampling rate allows continual adaptation to telephone-line conditions

•Full-time telco echo cancellation with 26 millisecond tail time

•Conference up to 16 callers (with 16 AP10s) within an Audio Perfect system

•Digital anti-alias filter minimizes hum and Central Office switching noise

•Remote On/Off control via serial commands or rear-panel connection

•Digital send filter/limiter for telephone line noise reduction

•Compatible with any analog telephone system

•No outside RF interference will affect performance
