NameTypeRangeBehavior
AttackknobSets the attack time of the envelope follower circuit.1046
Audio LevelknobControls the output level of the amplified audio signal independently from the envelope output level.1046
DecayknobSets the decay time of the envelope follower circuit.1046
Envelope LevelknobControls the output level of the envelope follower signal, independently from the audio output level.1046
Input ImpedanceswitchSelects the input impedance to match instrument-level or line-level sources.1046
Phantom PowerswitchSelects whether +48V phantom power is supplied to the input, enabling use of condenser microphones.1046
