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

!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.
