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.
- Allows for a 1/4th inch inputs with gain staging for interfacing with guitars or other synthesizers
- An Envelope Follower provides a CV level that mimics the Amplitude level of the incoming signal
- A threshold control and gate output allows the user to decided a level which must be crossed to generate a Gate output. Great for synchronizing rhythms to an external audio rhythm.
