12. Aux Mon

These knobs tap a portion of each channel's signal to 

set up a nice monitor mix feeding stage monitors,    
independent of the main mix. Adjust these controls on 
each channel until the band is happy with the stage 
monitor mix.

The controls are off when fully turned down, deliver 

unity gain at the center detent, and can provide up to  
15 dB of gain turned fully up.

The pan switch and channel level do not affect the 

monitor output, but the other channel controls will.  
The aux mon is pre-fader, so adjusting the channel's 
level control will not affect the aux mon output level.

The overall output level may be adjusted with the aux 

master mon knob and monitor's EQ tweaked with the 
graphic EQ if the main mix/mon switch is engaged. 
Internal FX may also be added to the monitor mix with 
the FX to mon knob.

13. Aux FX

These knobs tap a portion of each channel's signal to 

set up a nice FX mix feeding the internal FX processor, 
and to feed external processors via the FX send.

The controls are off when fully turned down, deliver 

unity gain at the center detent, and can provide up  
to 15 dB of gain turned fully up.

The channel level and other channel controls affect 

the FX output, but the pan switch does not. The aux  
FX is post-fader.

The FX signal reaching the internal FX processor 

and the FX send output jack is the sum (mix) of all 
the channels whose aux FX control is set to more than 
minimum. 

FX are added to the main mix by increasing the level 

of the FX to main knob. Internal FX may also be added 
to the monitor mix by increasing the level of the FX  
to mon knob.

14. Stereo Pan Switch (Ch. 1–2)

With this switch out, each mono channel feeds  

both the left and right sides of the main mix equally.  
For example:

• Playing a mono source: If you talk into a  

microphone connected to input 1, your sweet tones  
will be heard in both the left and right loudspeakers.

• Overdubbing a mono source: if you are  

monitoring directly through the headphones, you  
can hear the overdub signal in both ears while you  
are playing.

With this switch pressed in, channel 1 will play only  

in the left side of the main mix, and channel 2 will play 
in the right side. For example:

• Recording a stereo source: If you have a stereo 

microphone connected to the mic inputs, or if you are 
playing a stereo source into the line inputs, each side  
of the source can be recorded discretely onto a recorder 
connected to the main or tape outputs.

The pan switch does not affect channels 3 or 4,  

or the tape inputs.

15. Level

This is the last control in a channel’s signal path, and 

it adjusts the level of each channel onto the main mix. 
The “U” mark  indicates unity gain, meaning no increase 
or decrease of signal level. All the way up provides an 
additional 10 dB, should you need to boost a section of 
a song. If you find that the overall level is too quiet or 
too loud with the level near unity, check that the gain 
control is set correctly.
