EQ features

Many audio signals coming into the console require some degree of corrective equaliza- tion 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 overlapping adjacent bands.

6high frequency—HF

15dB boost and cut at 12kHz—Shelving Response

7high-mid frequency—HM

Selectable frequency range of 500Hz to 10 kHz

The response is bell-shaped with a fixed Q of 1.5.

15dB boost and cut centered at the selected frequency

8low-mid frequency—LM

Selectable frequency range of 100Hz to 2kHz.

The response is bell-shaped with a fixed Q of 1.5.

15dB boost and cut centered at the selected frequency

9low frequency—LF

15dB boost and cut at 80Hz—Shelving Response

When the button is “OUT,” the EQ circuits are bypassed.

When the button is “IN,” the EQ circuits are engaged. This switch can be used to make A/B comparisons between "flat" and equalized signals.

aux send features

Ten aux sends are available for creating individual output mixes. These mixes can be used for driving effects processors, providing monitor mixes, creating broadcast or alternate sound reinforcement mixes, or other special requirements. With the corresponding PRE switches in the “OUT” position, the Aux sends are fed from the Post-fader channel signal. When the PRE switch is depressed (“IN”), the corresponding Aux sends are fed from the Channel’s Post-EQ, Pre-fader signal. An internal option allows the user to change this PRE point to the Pre-Insert, Pre-EQ signal on a channel-by-channel basis. All Aux sends are affected by the channel Mute switch.
