Processing
Automatic mixer with four gated microphone inputs and
three line level inputs. The microphone inputs provide
switchable 24-V phantom power and an integrated,
adjustable compressor/leveler that compensates for
variations in level due to variations in working distance. A
switchable ducking function will attenuate all other chan-
nels when signal is present at the MIC 1 input. The master
output section provides bass and treble controls.
