Input Section

Gain settings can be adjusted individually for each channel. The MIC Gain control 
of channel 5 can be specifi ed as Master Gain control to control all 5 gain settings at 
a time—the motorized potentiometers ensure coherent gain settings for all chan-
nels with highest precision.

The microphone inputs are equipped with phantom power supply, switchable 
insert, pad (-25 dBu), phase reverse and high pass fi lter (100 Hz/50 Hz). 

For direct recordings of the preamplifi ed signals recording devices like a multitrack 
recorder can be connected to the insert Tape Send. Signals coming back from the 
recorder  can be connected to the insert Tape Return, for example to use the pano-
rama matrix or further Atmos 5.1 features.

The VU meters display the input level of each channel after the preamplifi er 
stages. 

The insert Tape Return can also be used like a usual line input for external sources, 
e g. to use all Atmos 5.1‘s features for a surround mix.

Fader

The fader allows adjustments of the signal level that is routed either to the direct 
channel outputs, to the panorama matrix or to the outputs.
