NOTE: The PAD position should be used with high input levels, like the ones obtained when
using high sensitivity microphones. But for a better signal to noise ratio it is better to
use the mixer without PAD if possible.
4.3.3 Gain (LO 2 3 HI)
This four positions switch allows you to adjust the gain level of the corresponding input channel
(IN1 to IN4) according to the following:
LO position: an input gain of 16dB is activated.
2 position: an input gain of 36dB is activated.
3 position: an input gain of 56dB is activated.
HI position: an input gain of 76dB is activated.
NOTE: Gain control should be used with care since the adjustment range is extensive. A
signal level set too high can cause distortion and will leave you with less headroom; a
level set too low can cause a bad signal-to-noise ratio.
4.3.4 LF filter (80 LIN 120)
This switch allows you to turn ON or OFF the low frequencies filter of the corresponding input
channel (IN1 to IN4) according to the following:
80 position: the low cut frequency is 80 Hz, the slope is 12dB/octave.
LIN position: the low cut filter is turned OFF.
120 position: the low cut frequency is 120 Hz, the slope is 12dB/octave.
NOTE: You can use this filter to remove unwanted low frequency noises such as room rumble,
wind noise, popping, etc.
4.3.5
Pan (MS L C R)
This switch allows you to route the audio signal of the corresponding input channel (IN1 to IN4)
to the main outputs, according to the following:
MS position: a MS decoded signal is routed on both Left and Right output channels.
L position: the signal is routed on the Left output channel only.
C position: the signal is routed on both, Left and Right output channels.
R position: the signal is route on the Right output channel only.
NOTE: The MS position is only available on channels 2 and 4, to activate MS on inputs 1-2,
and/or inputs 3-4.
In the MS-mode the M channel is routed to both Left and Right output channels in phase and
the S channel is routed in phase to the Left output channel and out of phase to the Right output
channel.
WARNING:
When the MS position is selected on input channel 2 and/or 4, the pan setting for
input channel 1 and/or 3 will have no effects and thus becomes useless.
4.3.6
Input level link (LINK 1 to 2 and LINK 3 to 4)
This switch allows you to link level controls (rotary faders) of input channels 1 and 2 (and
respectively input channels 3 and 4) to the single level control of input channel 2 (respectively
