Eurorack Doepfer A119 Ext in

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
