stereo MASTERS. Conversely, if the fader
must be pulled way back to get the right level,
the GAIN control or stereo MASTERS should
be adjusted. Adjust the GAIN control if you
see a PEAK LED indication, otherwise adjust
the stereo MASTERS. For optimum perform¬
ance, the channel FADERS should always be
run as close to the "10" mark as possible.
IG. CHANNEL PEAK LED
The channel PEAK LED monitors the input
channel circuit for clipping or overload (both
before and after the EQ section). If it lights,
you are bordering on distortion. You'll hear
this in the output as a harsh, blaring sound on
volume peaks. This might be caused by
excessive boost in the channel equalization
controls (sect. IB), or a GAIN control setting
that is too high for the input signal (sect.
1A). Generally, readjusting the GAIN control
(sect. 1A) will suffice.
IH. CHANNEL PATCHING INSERT JACK
This space saving (two-connectors-in-one)
jack allows you to add external signal
processing gear to a particular channel, with¬
out disturbing any of the other channels. A
3-conductor (stereo) phone plug is used for
both the output from the channel preamp,
and for the return to the mixer's output
stages from the external processing device.
The diagram indicates how a channel patching
cord should be wired. These can also be
purchased from PRO-CO SOUND or other
audio cable manufacturers.
HOWTO WIRE A CHANNEL PATCHING CORD
The channel patching jack can be used with
equalizers, limiters, compressors, external
reverb or delay systems and the like. Just be
sure the device you want to patch in has//ne
level unbalanced inputs and outputs. The
signal at the insert jack can drive loads of
2000 ohms or greater, and the external
processing device should have a low output
internal impedance (100 ohms or less).
A nominal input signal is a level of —10 dB.
the maximum level is +20 dB.
