features

input gain—GAIN

This control adjust the gain of the input preamp(s).

Both left and right input signals are affected by this control.

polarity reverse—ø

This switch inverts the polarity of the right input signal in relation to the left input signal.

see—mono input module

Polarity of the right input signal is inverted.

Polarity of the right input signal is not inverted.

high-pass filter—HPF

The high-pass filter is activated for signals coming into both the left and right inputs.The shelving frequency is fixed at 80Hz with a slope of 12dB per octave.

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.
