The stereo (aux) returns are designed for 1/4" TRS 

balanced or 1/4" TS unbalanced signals, from -20 dB to 
+20 dB. They allow the stereo processed output from 
external effects processors or other devices to be added 
to the main mix.

Level adjustment of the incoming signals is made with 

the stereo return controls [54].

You may also use these inputs to add any stereo  

line-level signals to your main mix, so it could be  
another line-level source, not just an effects processor.

If you are connecting a mono source, use the left 

(mono) stereo return input, and the mono signals will 
appear on both sides of the main mix.

The stereo unbalanced RCA inputs allow you to play a 

tape, CD player, iPod

®

 dock, or other line-level source. 

The tape in jacks accept an unbalanced signal using 
standard hi-fi hookup cables.

The stereo unbalanced RCA outputs allow you to 

record the main stereo mix onto a tape deck, hard disk 
recorder, or automatic CD burner, for example. This 
lets you make a recording for posterity/archive/legal  
purposes whenever the band gets back together again.

The tape output is the stereo main mix, and it is not 

affected by the main mix level control [75].

 

The output 

could also be used as an extra set of main outputs for 
feeding another zone.

 

These unbalanced 1/4" jacks are for connecting serial 

 effects processors such as compressors, equalizers, 
de-essers, or filters. The insert point is after the gain 
control [23] and low cut filter [24], but before the 
channel’s EQ [31-36] and level [43].

 

The channel signal 

can go out of the insert jack to an external device, be 
processed and come back in on the same insert jack. 
To do this requires a standard insert cable that must be 
wired thusly:

Tip = send (output to effects device)
Ring = return (input from effects device)
Sleeve = common ground

Insert jacks may be used as channel direct outputs; 

post-gain, and pre-EQ. See the connector section on 
page 30 (figure G) showing three ways to use insert 
cables.

The stereo line inputs are designed for 1/4" TRS   

balanced or 1/4" TS unbalanced signals. They may   
accept any line-level instrument, effects device, CD 
player, etc. 

Level control is available -20 dB to +20 dB if you are 

connecting a mono source. Use the left (mono) stereo 
return input, and the mono signals will appear on both 
sides of the main mix.
