12. FX RTN 1 and FX RTN 2

These 1/4" TRS input connectors allow you to add
the stereo processed output from external effects
processors to the main mix. Adjustment of the incom-
ing signals is made with the FX return faders [57]. The
signals can also be muted and soloed (and so cued up in
headphones) like any other input.
You can also use these inputs to add any stereo line-
level signals to your main mix, so it could be another
source, not just an effects processor. The inputs are
similar to the channel line-level inputs, only without the
gain control, channel EQ or pan. A sample of the FX 1
return can be added to monitor 1 and 2 using the FX 1
to mon 1 [56] and FX 1 to mon 2 controls.

13. TAPE INPUTS

These stereo unbalanced RCA inputs allow you to play
a tape, CD or other line-level source whenever the band
is taking a break. The input is only enabled when the
break switch [51] is engaged, at which time, the main
mix is bypassed, and only the tape input will play in the
main loudspeakers.

14. TAPE OUTPUTS

These stereo unbalanced RCA outputs allow you
to record the main stereo mix onto a tape deck, hard
disk recorder, automatic CD burner, or a computer, for
example. This lets you make a recording for poster-
ity/archive/legal purposes whenever the band gets back
together again.
The tape output is the stereo main mix, but it is not
affected by the main fader [59], or the main graphic EQ
[44].

15. MAIN INSERTS

These unbalanced 1/4" TRS jacks can be used for
connecting serial effects processors such as compres-
sors, equalizers, de-essers, or filters. The insert point
is before the main mix master graphic EQ [44] and the
main mix fader [59]. The main mix signals can go out of
the insert jack to an external device, be processed (or
whatever) and come back in on the same insert jack.
To do this requires a special insert cable that must be
wired thusly (just like a channel insert):
ring
(TRS plug)
tip
sleeve
This plug connects to one of the
mixer's Channel Insert jacks.
Tip = send (output to effects device)
Ring = return (input from effects device)
Sleeve = common ground

16. MAIN OUTPUTS

stereo main mix at line-level. You can connect these
outputs to the line-level inputs of external power ampli-
fiers running passive loudspeakers, or to the inputs of
powered loudspeakers. This is useful if you need more
power, or if you already have this equipment. Then you
can use the internal amplifiers to power other loud-
speakers, such as passive monitors, after setting the
amp mode switch [53] appropriately.
speaker-level outputs [3] (when set to stereo mains).

17. MAIN MONO OUTPUT

the main mix summed together in glorious living mono.
This is ideal for running a mono PA system, by connect-
ing to the inputs of an external power amplifier running
a passive loudspeaker, or directly to a powered loud-
speaker. Whatever adjustments you make to the main
mix, will affect this output. The output here can be
adjusted with the mono out control [55], and turned up
or down relative to the main left and right outputs.
gaged, the mono output passes only the frequency
range below the frequency set by the low-pass control
[54]. This allows you to use the mono output to run to
the inputs of powered subwoofers, or to the inputs of
amplifiers running passive subwoofers. (The main left
and right outputs still play the full frequency range.)
Tweaking the mono out control will allow you to balance
the subwoofer output with the left and right mains.
