About the input channels

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.

INPUT
PATCHBAY
• INPUT PATCHBAY
This section patches input ports to input channels.
• φ (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 hi-pass 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.
• DELAY
This delays the input signal.
• EXT FX INSERT (External effect insert)*
An external effects processor can be inserted at this point
using the rear panel CONSOLE IN1–8 and CONSOLE OUT1–
OUT8 jacks.
• FX INSERT (Effect insert)*
FX1–FX6 can be inserted at this point.
• 4-BAND EQ*
This is an EQ with four bands.

• MUTE
This mutes the channel.
• FADER
This adjusts the send level to the MAIN.
• PAN
This adjusts the left/right panning of the audio signal sent to
the MAIN.
• 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
• 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
• DIRECT OUT POINT
This specifies the position from which the direct out signal is
taken.
