7. Left/Right Main Outs: XLR & 1/4"

The male XLR connectors provide a balanced 

 

line-level signal that represents the end of the mixer 
chain, where the fully mixed stereo signal enters the 
real world. Connect these to the left or right inputs of 
your main power amplifiers, powered speakers, or serial 
effects processor (like a graphic equalizer or  

 

compressor/limiter). The XLR outputs are 6 dB 

 

hotter than the TRS outputs.

The 1/4" TRS output connectors provide balanced or 

unbalanced line-level signals. Connect these to the next 
device in the signal chain like an external processor 
(compressor/limiter), or directly to the inputs of the 
main amplifier. These are the same signal that appears 
at the XLR main outputs, but 6 dB lower when the XLR 
is used balanced.

8. Main Inserts

These 1/4" TRS jacks are for connecting serial effects 

such as compressors, equalizers, deessers, or filters. 

 

The insert point is after the mix amps, but before the 
main mix fader [75]. Refer to the description of the  
channel insert on the previous page to see how to 

 

make this connection.

9. Mono Out

The male XLR connector [balanced] and 1/4" TRS 

output connector [balanced or unbalanced] provide 

a line-level signal that is a combination of the left and 

right main out [7] signals (L+R). You may use this for 
a separate mix that does not require a stereo feed, or 
to simply test the monaural compatibility of the stereo 
mix. Again, when used balanced, the XLR signal is 6 dB 
higher than that from the TRS jack.

10. Mono Out Level Control

This is a separate level control for the mono out [9]. 

It comes after the main mix fader [75], so turning the 
main mix fader up and down does affect the mono out 
signal. With this control turned all the way up, you will 
have 6 dB of extra gain at the mono out.

11. Group Outs 1-4

These 1/4" TRS jacks provide balanced or unbalanced 

line-level signals and are typically patched to the  
inputs of a multitrack deck, or to secondary amplifiers 
in a complex installation.

12. Group Inserts

These 1/4" TRS jacks are for connecting serial effects 

such as compressors, equalizers, de-essers, or filters. 
The insert point is after the mix amps, but before the 
group send masters [74] (and after the built-in stereo 
compressor [72]). Refer to the description of the  
channel insert [3] on the previous page to see how to 

make this connection.

13. Aux Sends 1-6

These 1/4" TRS connectors allow you to send balanced 

or unbalanced line-level outputs to external effects 
devices, headphone amplifiers, or stage monitors. These 
could either be passive stage monitors powered by an 
external amplifier, or powered stage monitors with built-
in power amplifiers. All six auxes are independent of 
each other, so you can run up to six separate aux mixes. 

Aux sends 3-4 may either be pre or post fader,  

depending on the position of the pre/post switches [28]. 
For stage monitor work, use pre, so the stage monitors 
do not increase in volume when the channel level is 
adjusted. Imagine how upsetting that can be to big hairy 
drummers. This allows you to set up the monitor mix 
and levels just right, and not have it change every time 

 

a channel level is adjusted.

For external processors, use post. In this way, the 

feed to external processors will vary with the channel 
level, so the level of any returned effect (like an echo) 
will also change if the channel level is changed, keeping 
them in the same ratio (wet/dry).
