+48V Switch/Indicator
This switch toggles phantom power on and off for a
monaural channel. When the switch is turned on, the
+48V indicator will light, and DC +48V phantom power
will be supplied to Pin 2 and 3 of the corresponding
XLR-type INPUT A jacks. Turn this switch on when using
a phantom-powered condenser microphone.
6
26 dB (PAD) Switch
When this switch is turned on, the input signal from the
INPUT jack of the monaural channel is attenuated by 26
dB. Turn the switch off ( ) if you’ve connected a
microphone or other device with a low input level to the
channel. Turn it on ( ) if you’ve connected a line-level
device.
7
GAIN Control
This adjusts the sensitivity of the input signal from the
INPUT jack. Monaural channels have a 26 dB switch
(
6
) that lets you change the range of this control. The
adjustable sensitivity range is as follows.
Monaural channel
Stereo channel
-34dB to +10dB
8
(Phase) Switch
Turning this switch on will invert the phase of the input
signal. Turn this switch on if you need to mix a phase-
reversed signal.
NOTE
· If you try to mix a phase-reversed signal, the signals will
interfere with each other, resulting in degraded sound
quality.
9
(High Pass Filter) Switch
This switch toggles the HPF on or off.
Turning this switch ON will apply a high-pass filter that
attenuates the signal below 80 Hz by a slope of 12 dB/
octave.

Be sure to leave this switch off if you do not need
phantom power.
•When turning phantom power on, be sure that only a
condenser microphone is connected to the INPUT A
jack of the monaural channel. Other devices may be
damaged if connected to phantom power. This precau-
tion does not apply to balanced dynamic microphones,
however, as these will not be affected by phantom
power.
•To avoid damage to speakers, be sure to turn off
amplifiers (or powered speakers) before turning this
switch on or off. It’s also a good idea to turn the mixer’s
output controls - STEREO OUT master fader and
GROUP OUT faders - all the way down. If you omit this
precaution, you may damage your hearing or your
equipment.
