Controls and Connectors
• BAL: Sets the volume balance of the signal sent from
each stereo input channel (L/R) to the STEREO
L/R bus or GROUP bus. When this knob is set to
the 12 o’clock position, the sound of the stereo
input channels (L/R) will be sent to the STEREO
L/R bus or GROUP 1, 3/2, 4 bus at the same vol-
ume.
• PAN/ BAL: This knob performs both [PAN] and [BAL]
functions. You can use this as a [PAN] control
when sound is input to the [LINE] (L/MONO) jack,
and as a [BAL] control when sound is input to
both the [LINE] (L) and [LINE] (R) jacks.
!3 [ON] switches
Turn this switch on ( ) to send the respective channel’s
signal to the buses. The switch lights when on. When this
switch is off ( ), the respective signal input is not sent to
the AUX bus or GROUP bus.
NOTE
• Even if the [ON] switch is off, the PFL signal from each chan-
nel can still be monitored via the [PHONES] jack.
• To minimize noise, turn the [ON] switch off for any unused
channels.
!4 [PEAK] indicators
The peak level of the post-EQ signal is detected, and the
PEAK indicator lights red when the level reaches 3 dB below
clipping.
!5 Bus assign switch
These switches determine the bus(es) to which each channel’s
signal is sent. Turn the switch on ( ) to output the signal to
the corresponding buses.
• [1-2] switch: Assigns the channel’s signal to the
GROUP 1-2 buses.
• [3-4] switch: Assigns the channel’s signal to the
GROUP 3-4 buses.
• [ST] switch: Assigns the channel’s signal to the STE-
REO L/R buses.
NOTE
To send the signal to each bus, engage the [ON] switch !3.
!6 [PFL] (Pre-fader Listen) switch
When the [PFL] switch is on ( ), the channel pre-fader
signal is output to the [MONITOR OUT] and [PHONES]
jacks for monitoring. In this condition, the audio from the
STEREO L/R buses or GROUP buses that could be heard in
the [MONITOR OUT] and [PHONES] jacks can no longer be
heard. When a [PFL] switch is turned on, the [PFL] indicator
below the level meter flashes.
!7 Channel faders
For adjusting the level of the channel signal. Use these con-
trols to adjust the balance between the various channels.
NOTE
To minimize noise, set the fader sliders for any unused chan-
nels all the way down.
