EQ features
The X-VCA Stereo Input module offers four bands of EQ - High, High mid, Low
mid and Low.The High and Low are shelving type EQ and the High mid and Low
mid have a fixed (non-adjustable) Q of 1. Although the left and right signals are
processed separately, the paramaters are set in tandem by common front panel
controls.
high frequency—HF
Frequency Continuously sweepable between 1kHz and 20kHz
Boost / Cut 15dB boost and cut.
high mid—HM
Frequency Continuously sweepable between 400 Hz and 8 kHz.
Boost / Cut 15dB boost and cut.
Low mid—LM
Frequency Continuously sweepable between 100 Hz and 2 kHz.
Boost / Cut 15dB boost and cut.
Low frequency—LF
Frequency Continuously sweepable between 40 Hz and 800Hz.

eq on
Equalizer is on. This switch is used to activate the EQ section and can be
used to make A/B comparisons between "flat" and eq'd signals.
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 exam-
ple, 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
When the high-pass filter is on, this control selects a frequency between
20Hz and 400Hz as the point where attenuation begins.
