EQ features

Many audio signals coming into the console require some degree of cor- rective eq in order to be part of a good sounding mix.

The input eq consists of four-bands: high, high-mid, low-mid and low. The high and low bands have fixed frequencies while the high-mid and low- mid bands are sweepable, with their higher and lower frequencies over- lapping adjacent bands.

high frequency—HF

15dB boost and cut at 12kHz.

The boost response is bell-shaped and the cut response is shelving.

high-mid frequency—HM

15dB boost and cut.

Selectable frequency range of 400Hz to 8 kHz.

The response is bell shaped with a fixed Q of 1.5

low-mid frequency—LM

15dB boost and cut

Selectable frequency range of 80Hz to 2 kHz.

The response is bell shaped with a fixed Q of 1.5

low frequency—LF

15dB boost and cut at 80Hz.

The boost response is bell-shaped and the cut response is shelving.

eq on

Equalizer is on. This switch can be used to make A/B comparisons between "flat" and eq'd signals.
