MIXING TO MAIN L&R BUSES
To create a simple mix to the Main L&R outputs:
1. Connect your inputs to the Mic/Line inputs on the console.
2. Connect the PA to Analogue Outputs 15 & 16.
3. Connect headphones to the socket under the armrest.
4. Adjust the gain to achieve a ‘good’ level on each channel, as a guide the -12dB indicator
should be on most of the time with only the most occasional ‘flickering’ of the 0dB led.
5. To control any individual channel bring it to the ACS by pressing the SELect key, and
to hear it in your headphones press the associated SOLO key and turn up the monitor
volume control.
6. Raise the master fader to ~0dB.
7. Raise the channel faders and balance your mix.
8. To control the processing of the main mix press the SELect key above the main L&R
fader to assign the ACS to the main L&R bus.
a) You may now open the GEQ for the main L&R bus by pressing either the GEQ HI or
LO key, close the GEQ by pressing the lit HI/LO key again.
NOTE: This assumes you are starting from a factory default state. To reset the console
completely see ‘Factory Reset’
MIXING TO AUX BUSES
To create a simple mix to Mix 1:
1. Connect a monitor to Analogue Outputs 1.
2. Select fader bank A.
3. Press the Mix 1 follow key; notice the input faders have changed colour & position as
they are now your sends from the input channels TO Mix Bus 1. Also note the SEL key
over the MONO/SEL fader is lit and the FaderGlow has changed colour to Yellow, this is
now Mix 1 Master fader.
4. Raise the channel faders and balance your mix, note that the Si EXPRESSION has already
SOLOd the bus for you enabling you to hear it without the need to press any other keys.
5. To control the processing of the mix use the controls on the ACS.
a) You may now open the GEQ for Mix 1 by pressing either the GEQ HI or LO key, close
the GEQ by pressing the lit HI/LO key again.
NOTE: By default mixes 11-14 are set POST fade for ‘more typical’ application as a sub-group,
this can be changed for the active mix in the OUTPUTS menu.
NOTE: Assumes you have first created a main L&R mix as described.
NOTE: Aux mixes 9-14 may be set to operate as mono or stereo without affecting the number
of simultaneous independent mixes you can have.
NOTE: Unassigned faders or faders not assigned to inputs are unlit and have no function
whilst mixing to a mix bus.
NOTE: If the active mix is stereo the encoder above the fader will act as channel to mix pan
control (channel to bus balance if input is stereo and mix is stereo).
