1. Gain (Trim)
Controls the gain of the microphone preamp.
Range is from +22 dB to +60 dB to accomodate
different input sources. Can be thought of as a
"coarse" gain adjustment.
2. Channel Fader
Controls a channel's gain. Ranges from 'off' to
+15 dB. Nominal setting is in the middle (0 dB).
Can be thought of as a "fine" gain adjustment.
3. Channel Pan
Controls the Left/Right balance of the input signal
to the outputs. Signal is 3 dB greater than center
position when panned hard right or left.
4. LINK LED
Indicates that channels 1 and 2 are linked as a
stereo pair, set via the Link Switch on the input
panel.
5. Channel 2 Polarity Reverse
Reverses the polarity of input channel 2.
6. PFL (Solo)
Sends the channel signal to the headphones for
troubleshooting and gain set-up. Does not affect
master output signal at all.
7. Peak LED
Indicates that the input signal is 3 dB from clip-
ping. Indicates that Gain is set too high if LED
comes on.
8. High-Pass Filter
Adjusts corner (-3 dB) frequency of high-pass
filter. Fully counter-clockwise (detented) removes
the high-pass filter. Range is 80 Hz to 240 Hz,
12dB/oct to 6 dB/oct.
9. Input Limiter LED
Illuminates orange in proportion to the amount of
input limiting. Indicates that Gain Trim is set too
high if significant limiting is occurring.

iters can be defeated in the Setup Menu. ON =
output limiters are not linked to each other. LINK
= output limiters are linked to each other for ste-
reo outputs.
12. Master Gain
Controls overall level of signals to both left and
right outputs.
13. Meter Brightness
Adjusts the overall mixer LED brightness level
among four intensities (or meter off).
14. Meter Ballistics Selection
Selects among output meter ballistics—VU, PPM
(Peak), combined VU/PPM, or VU-PPMHold (see
Metering). Hold down while powering to access
the Setup Menu.
15. Monitor Selection Switch
Sets the signal source sent to headphones.
Options include: input PFL 1, 2, 3; left output bus;
right output bus; Mono (summed left and right);
STereo master; RTN - stereo monitor return;
MS-mono; MS-stereo; RTN-MS.
