Input channel operations
The input channels process the audio signals from the input jacks and internal ports, and send them to the MAIN bus and AUX/MTX buses.

PATCHBAY
•
INPUT PATCHBAY
This section patches input ports to input channels.
•
PHASE
This reverses the phase of the audio signal.
•
ATT (Attenuator)
This adjusts the input level in the digital domain.
• HPF (High-pass filter)
This is a 12 dB/octave filter that passes the region higher
than the specified frequency.
• GATE/EXPANDER
This is a dynamics processor that can be used as a gate,
expander, or ducking.
•
COMPRESSOR
This is a dynamics processor that can be used as a
compressor.
• EXT FX INSERT (External effect insert)
An external effects processor can be inserted at this point
using the rear panel CONSOLE IN
5
–8 and CONSOLE OUT

–
OUT8 jacks.
•
FX INSERT (Effect insert)
FX1–FX4 can be inserted at this point.
•
4-BAND EQ
This is a 4-band EQ with LO, LO-MID, HI-MID, and HI
frequency bands.
• MUTE
This mutes the channel. The signal sent to the MAIN L/R bus,
the AUX buses, and the direct out will be muted.
•
FADER
This adjusts the send level to the MAIN bus.
•
PAN
This adjusts the left/right panning of the audio signal sent to
the MAIN L/R bus.
• CENTER
When LCR SW is on, this specifies the proportion of the
signal that is sent to MAIN C when PAN is at center.
• LCR SW (LCR switch)
When turn this on, PAN will operate across the three outputs
MAIN L, MAIN C, and MAIN R.
• MAIN SW (Main switch)
This turns the send to the MAIN L/R
/C
bus on/off.
• LR SW / C SW
These individually turn the send to the MAIN L/R and MAIN C
bus on/off.
• AUX
/MTX SENDS
These adjust the send to the AUX
/MTX
bus.
•
DIRECT OUT POINT
This specifies the position from which the direct out signal is
taken.
