The insert point is after the gain control [19], level
set LED [20] and low cut switch [21], but before the
channel EQ [22-24] and fader [30]. The channel signal
may 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:
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 28 (figure F) showing three ways to use insert
connections.
11. STEREO RETURN
This is where to connect the outputs of parallel
effects devices (or extra audio sources). The circuits
will handle stereo or mono, balanced or unbalanced
signals. They may be used with just about any pro or
semi-pro effects device or line-level source on the
market. The signals coming into these inputs may be
adjusted using the stereo return fader [44] before
passing onto the main mix bus (see page 23). Signals
coming in here may also be quickly muted with the
mute switch [43], and the OL LED [42] will illuminate
if the incoming signal is too high.
Stereo Device: If using a stereo parallel effects device
(two cords), use stereo return left and right.
Mono Device: If using an effects device with a mono
output (one cord), plug that into the stereo return left/
mono, and leave the right unplugged. The signal will be
sent to both sides, magically appearing in the center as
a mono signal.
8. MONO LINE INPUTS
These 1/4" jacks share circuitry (but not phantom
power) with the mic preamps and may be driven by
balanced or unbalanced sources.
To connect balanced lines to these inputs, use a
1⁄4" Tip-Ring-Sleeve (TRS) plug.
To connect unbalanced lines to these inputs, use a
1⁄4" mono (TS) phone plug or instrument cable.
If using a stereo source, and the stereo
and hybrid channels are in use, utilize two
mono channels instead. Traditionally, an
odd-numbered channel receives the left signal. For
example, feed the ProFX mixer a stereo signal by
inserting the device’s left output plug into the
channel 1 jack (panned fully left) and its right output
plug into the channel 2 jack (panned fully right).
9. STEREO LINE INPUTS
These 1/4" jacks may be driven by stereo or mono,
balanced or unbalanced sources. They may be used
with just about any professional or semi-pro
instrument, effect or tape player.
To connect balanced lines to these inputs, use a 1⁄4"
Tip-Ring-Sleeve (TRS) plug.
To connect unbalanced lines to these inputs, use a
1⁄4" mono (TS) phone plug or instrument cable.
If using just a mono source, plug it into the left input
(labeled mono) and the signal will appear (as if by
magic) equally on the left and right of the main mix.
10. CHANNEL INSERT
These unbalanced 1/4" jacks are for connecting serial
effects processors such as compressors, equalizers,
de-essers, or filters.
We’ve included inserts for just the mono channels.
If using this kind of processing on other channels,
simply patch through the processor before plugging
into the ProFX mixer.
