5. Stereo Returns 1-2
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.
6. Tape Ins / Outs
The stereo unbalanced RCA inputs allow you to play
a 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 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.
3. Insert
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.
4. Stereo Line Ins
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.
