Gain
The Input gain control range is closely related to the status of the PAD switch and the LINE
switch. In order to establish proper gain structure in the console, input gain settings must
be set correctly.
LINE—switch-up PAD —switch-up
12 to 72dB of gain can be added the mic-input signal.
The impedance at the input XLR is 4kΩ.
LINE—switch-up PAD —switch-down
-16 to 44dB of gain can be added to the mic-input signal.
The impedance at the input XLR is 4kΩ.
LINE—switch-down PA D —switch-up or -down
-10 to 45dB of gain can be added the line-input signal.
The impedance at the input XLR and input 1/4" TRS is 20kΩ.
High-pass filter—HPF
Proper use of the high-pass filter reduces or eliminates unwanted low frequencies without
substantially affecting the program material.Quite often such unwanted low frequencies are
included with in-coming mic- or line-input signals. For example, stage rumble or wind can
be picked up through vocal mics.The slope of the high-pass filter is -12dB per octave.
HPF
High-pass filter is on.
HPF—variable control
When the high-pass filter is on, this control selects a frequency between 20Hz and
400Hz as the point where attenuation begins.
If the channel peak
LED is illuminated,
first try lowering
the input gain control.
Only when this method is
unsuccessful should the pad
switch be engaged.
