Envelope Following

Envelope Follower Input: 

A signal present at the

 Envelope Follower 

Input 

will generate an envelope signal at the 

Positive

 and 

Negative 

Envelope Outputs

.

• 

If no signal is present at the 

Envelope Follower Input,

 either a mono 

sum of the signal present at the

 Stereo Line Input 

or the 

Microphone 

can be chosen as the normalled input source.

• 

If a normalled input source is active, patching a connection to the 

Envelope Follower Input

 will break the normal.

Response Curve Switch:

 Switch that determines the response curve of 

the variable envelope signal generated at the 

Positive

 and 

Negative 

Envelope Outputs

.

• 

If the switch is in the left position, a linear response curve will  
be selected

• 

If the switch is in the right position, a logarithmic attack/exponential 
release response curve will be selected.
