Doepfer A-119 External Input / Envelope Follower
NoiseBug Price : $99.00
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 envelope at its own output.
the comparator generates a gate signal whenever the input goes above an adjustable trigger threshold.
three leds help you keep track of overload, the envelope, and the gate signal.
this module has a maximum current draw of 30ma. it requires 8 te/hp worth of space to fit in a eurorack frame.
