EQ features
Many audio signals coming into the console require some degree of corrective equal-
ization in order to be part of a good sounding mix.
Each stereo input is equipped with a fixed-frequency, three-band EQ. The HF and LF
bands have a shelving response. The MF band is bell-shaped, centered at 3kHz. The
EQ circuitry is always in the signal path. Set all EQ controls to “0” (flat) if no equaliza-
tion is desired.
high frequency—HF— 15dB boost and cut at 10kHz—Shelving Response
mid frequency—MF— 15dB boost and cut centered at the 3kHz, Q of 1.5
low frequency—LF— 15dB boost and cut at 80Hz—Shelving Response
aux send features
Two aux sends are available for creating individual output mixes from the Stereo
Returns. These mixes can be used for driving effects processors, providing monitor
mixes, creating broadcast or alternate sound reinforcement mixes, or other special
requirements. The signal fed to each of the Auxes is a sum of the Left and Right stereo
signals. The Aux sends are normally fed from the Post-fader stereo signal. When the
PRE switch is depressed, the Aux sends are fed from the Post-EQ, Pre-fader signal. The
Aux sends are always affected by the Mute switch.
Aux 1/2 or 9/10 selector button
This button determines which Auxes receive the stereo return signal.
When the button is in the “OUT” position, Aux 1 and 2 are selected.
When the button is in the “IN” posiition, Aux 9 and 10 are selected.
PRE
The default signal source for the aux sends is post-fader. This switch is used for select-
ing the Pre-fader signal for the Aux sends. The Pre-fader signal is derived Post-EQ.
When the button is in the “OUT” position, aux sends are Post-fader.
When the button is in the “IN” position, aux sends are Pre-fader (Post-EQ)
aux sends (1-2 or 9-10)
These knobs adjust the amount of signal sent to the corresponding Aux buses. Unity
gain occurs at the zero setting, with 6dB additional gain available above that.
