Cong/Preamp
GAIN Rotary Control
On a microphone preamplier, input gain varies the amount of amplication applied to the microphone. Adjust the
preamp gain for the selected channel with the GAIN rotary control.
LED Display
The LED display in the Cong/Preamp section illustrates the signal input level for the selected channel. This is shown as
a value between 0 dB and -30 dB. When there is a signal present, but below -30 dB, the SIG LED is lit. When the signal
exceeds 0 dB the CLIP LED illuminates.
Please note that, when pressing the VIEW button, the signal input level displayed on the Main Display shows a value of
between 0 dB and -60 dB.
FREQUENCY Rotary Control
The FREQUENCY rotary control selects the frequency at which the low cut lter begins to lter unwanted frequencies for
the selected channel. The lter is engaged by pressing the LOW CUT button (see below).
Please note that the low cut lter is only available for the 32 primary input channels.
48V
Phantom power is a method for transmitting DC electric power through microphone cables to operate microphones that
contain active electronic circuitry. It is most commonly used with condenser microphones, though many active direct box-
es also use it. The technique is also used in other applications where power supply and signal communication take place
over the same wires. Press the 48V button to apply phantom power on the selected channel’s physical input.
Ø
An audio signal’s ‘phase’ refers to its position in a point of time along the waveform cycle, with each cycle being 360°. Press

the Ø button to reverse the selected channel’s phase by 180°. This can be useful when using the reverse phase function to
cancel noise across more than one channel.
LOW CUT
Press the LOW CUT button to engage the low cut lter for the selected channel.
Please note that the low cut lter is only available for the 32 primary input channels.
