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

FrequencyContinuously sweepable between 1kHz and 20kHz

Boost / Cut 15dB boost and cut.

high mid—HM

FrequencyContinuously sweepable between 400 Hz and 8 kHz.

Boost / Cut 15dB boost and cut.

Low mid—LM

FrequencyContinuously sweepable between 100 Hz and 2 kHz.

Boost / Cut 15dB boost and cut.

Low frequency—LF

FrequencyContinuously sweepable between 40 Hz and 800Hz.

Boost / Cut 15dB boost and cut.

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.

High-pass filter is on.
