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.
