1 Input selector switch
This switch selects the input connector via which the
source is connected to the channel. Leave the switch
out if the source is connected via the A (balanced XLR)
input connector. Push it in when the source is con-
nected via the B (balanced 1/4" phone) connector.
2 PAD switch
This switch attenuates the signal applied to channel (at
the corresponding A input connector or B input jack on
the top panel) by 20 dB prior to the head amplifier and
input gain control. This feature can be used to prevent
high-level signals from overloading the input circuitry,
allowing the mixer to handle a wider range of input
signal levels.
3 SIGNAL and PEAK LED indicators
These two LED indicators let you check the level of the
signal input to the channel. The green SIGNAL indica-
tor lights when a signal of 10 dB below the nominal
channel level is received. The red PEAK indicator lights
when the input signal reaches 3 dB below the
channel's clipping point. Both of these indicators show
the level of the post-EQ/pre-fader signal. If the PEAK
indicator lights more than briefly on high-level tran-
sients, you should use the PAD switch or the GAIN
control to decrease the input sensitivity of the channel.
If this does not work, reduce the output level of the
connected source.
4 GAIN control
This control adjusts the channel's input sensitivity
between –60 dB and –16 dB when the PAD switch is
off, or between –40 dB and +4 dB when the PAD
switch is on. Continuously variable gain control allows
optimum adjustment to virtually any microphone or line
source.
5 HPF switch
This switch causes the channel to be filtered through
an HPF with a 12 dB/octave roll-off at 80 Hz. This
feature is useful for reducing low-frequency noise such
as an AC mains hum or wind noise.
