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

15 to 75dB of gain can be added the mic-input signal. The impedance at the input XLR is 4kΩ.

LINE—switch-up PAD—switch-down -5 to 55dB of gain can be added to the mic-input signal. The impedance at the input XLR is 4kΩ.

LINE—switch-down PAD—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 fre- quencies 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 @ 80 Hz, 12 dB/octave

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.
