Stereo input section
26dB (PAD) switch
Turning this switch on (
) attenuates the input signal from 
the INPUT jack of the mono channel by 26dB. Turn this 
switch off (
) if you have connected a microphone or other 
device with a low input level to the channel. Turn it on (
if you have connected a line-level device.
+48V switch and indicator
Toggles phantom power on and off. When this switch is 
turned on (
), the mixer supplies DC +48V power to 
INPUT A of XLR input jacks. Turn this switch on when 
using one or more phantom-powered condenser microphones. 
The indicator is on when the switch is on.
CAUTION
• Be sure to leave this switch off (
) if you do not need 
phantom power.
• When turning phantom power on (
), follow the impor-
tant precautions below, in order to prevent noise and 
possible damage to the mixer and external devices.
• Turn this switch off when connecting a device that 
does not support phantom power to INPUT A of XLR 
input jacks 
• Do not connect/disconnect a cable to/from channels 1-
24 {1-16} while this switch on. 
• Turn the mixer’s output controls – STEREO master and 
GROUP faders- all the way down when turning phan-
tom power on/off.
GAIN knob
Adjusts the sensitivity of the input signal. Monaural channels 
have a 26dB switch (q) that lets you change the range of this 
control. The adjustable sensitivity range is as follows.
Mono channel
NOTE
The stereo channel is fixed to a range of -34dB to +10dB.
r
 (High Pass Filter) switch
Turning this switch on (
) will apply a high-pass filter that 
attenuates frequencies below 100Hz in the signal by a slope 
of 12dB/octave.
COMP knobs and indicator (Channel 9-24 {9-16})
Adjusts the amount of compression applied to the channel. 
As the knob is turned to the right the compression ratio 
increases while the output gain is automatically adjusted 
accordingly. The result is smoother, more even dynamics 
because louder signals are attenuated while the overall level 
is boosted. The COMP indicator comes on when the com-
pressor operates.
NOTE
Avoid setting the compression too high, as the higher average 
output level that results may lead to feedback.
