54. FADER:
Channel output level control. The level of the channel can be adjusted from off to +10 dB of
gain. The optimum setting is the "0" (unity gain) position.
Channel Functions 5 — 6 (RQ 2310), 9 — 10 RQ 2314 and 13 — 14 (RQ 2318):
In these two channels all controls are identical to the previous channels with the exception of the
insert jack. It is replaced by pad and polarity switches.

Channel Functions 7/8 — 9/10 (RQ 2310), 11/12 — 13/14 RQ 2314 and
15/16 — 17/18 (RQ 2318):
The Mic and Line inputs of these stereo channels can be used simultaneously. The following
features are found only on the the stereo channels.

59. LINE GAIN:
Varies the input gain of the Line Input to allow for a wide dynamic range.
Proper adjustment of the input gain will maximize the signal to noise ratio.
It should be set by depressing the PFL switch (53) and adjusting it for a
0 dBu level at the L-R meters. At this point there is 22 dB of headroom
remaining.
PAD:
When pressed it attenuates the input signal by 20 dB. This will increase
the dynamic range to accommodate a higher input level before clipping
which may be necessary when close miking loud guitar amplifiers or
drum kits.
POLARITY:
When pressed it reverses the phase of the input signal. This will
compensate for an out of phase input that would otherwise cause
frequency cancellations in the mix. (Often needed for drum mics where
both sides of the drum head are picked up in multiple mic situations.)
STEREO INPUTS:
1/4" balanced (TRS) high impedance input for high level signals. The tip
is the positive input, which should also be used for unbalanced inputs.
The Left/Mono Input supplies signal to both the left and right inputs if
there is no input connected to the right input jack. If the channel's input is
mono, the signal should be connected to the Left/Mono Input .
MIC GAIN:
Varies the input gain of the Mic Input to allow for a wide dynamic range.
Proper adjustment of the input gain will maximize the
signal to noise ratio. It should be set by depressing the
PFL switch (53) and adjusting it for a 0 dBu level at
the L-R meters. At this point there is 22 dB of
headroom remaining.
