The Channel Strip
48v Phantom Power
Engaging this switch provides 48 volt D.C phantom power to
the microphone input.
Individual phantom power switches on each channel provide
control over which microphones receive power.
Phantom power wiring
Microphone Preamplier Gain
Mic gain may be adjusted from 6 to 60dB.
The gain on offer is clean amplication and features a low-
noise, differential discrete transistor input stage.
Line Input Select
Engaging this switch overrides the microphone preamplifer, as
the channel source, and replaces it with the line input.
The mic/line path may also be replaced by the DAW input (8).
Polarity (Phase) Invert
A 180
o
polarity invert function is available for the microphone
preamplier or line input – useful for checking phase when
tracking with multiple microphones, or ipping an existing track
during mixdown. The function is achieved with a unity gain
inverting amplier.
This function is only available for the mic or line input, and not
for the DAW input - to invert the phase of a DAW input, use the
phase invert within your workstation software.)
High Pass Filter
A 75Hz high pass lter (HPF), with 12dB per octave roll-off, can
be engaged on the mic/line input path – useful for removing
unwanted low frequency content.
Many listeners use playback systems that can barely
reproduce 60-70Hz. Therefore, a well placed HPF on certain
sources can clean up unwanted mix elements, such as
microphone stand rumble and trafc noise.
This function is only available for the mic or line input, and not
for the DAW input - to lter a DAW input, use the equalisation
within your workstation software.
Direct Output Routing
The direct out is normally used as the record send to the DAW
The feed is taken from one of four different points in the
channel path, as illustrated on the next page:
● POST - post-fader
● PRE INS - pre-insert
● PRE FDR - pre-fader
● CH - from the channel input (mic/line path)
