Ext. Input / Envelope Follower

A-119

1. Introduction

Module A-119 (External Input / Envelope Follower)

is designed to allow external audio signals to be

integrated into the System A-100. It comprises a pre-

amp, envelope follower, and comparator.

The pre-amp has two inputs: an unbalanced input for

line level signals, with a gain factor of from 0 to 20, and

a balanced input with a gain factor of from 0 to 500,

for insertion of low level signals, for instance from a

microphone or electric guitar.

The Envelope Follower reads the signal level of the

input, and puts out a proportional voltage as an enve-

lope at its own output (see chapter 3. How it works).

The comparator generates a gate signal whenever the

input goes above an adjustable trigger threshold (see

chapter 3. How it works).

Three LEDs help you keep track of overload, the

envelope, and the gate signal.
