LOW VOLTAGE SPEECH NETWORK

INTRODUCTION

18-DIP-300A

The KA8503 is a telephone low voltage speech network which includes

mic amp. transmit amp, side-tone amp, receive amp. It handles the

voice signal performing the 2/4 wire interface and changing the gain

on both sending and receiving amplifiers to compensate for line at-

tenuation by sensing the line length through the line current. Applica-

tion dependent parameters such as amplitude of each amp, sidetone

level line balance, and frequency response are controlled by exter-

nal components. Each gain can be controlled by external component

exchange. The receiver output driving capability is adjustable.

FEATURES

· Adjust Sending and Receiving Attenuation Length

· Mute Function
