MIXING TO FX BUSES
To create a simple mix to FX Processor 1:
NOTE: This function may only be enabled if an FX processor
is patched to a stereo input; this is achieved from the PATCH
function in the inputs window.
1. Select fader bank A.
2. Press the FX1 follow key; notice the input faders have changed colour and position as
they are now your sends from the input channels TO FX Processor 1 whilst the ON keys
are now the routing ON/OFF from the channel to the FX bus. Also note the SEL key over
the MONO/SEL fader is lit and the FaderGlow has changed colour to Cyan as it operates
as the FX Return 1 Channel fader whilst in follow mode.
3. Raise the channel faders and balance your mix. Note that the Si EXPRESSION has already
SOLOd the FX Return for you, enabling you to hear it without the need to press any other keys.
4. To control the processing of the FX Return use the controls on the ACS.
5. Raise the Mono/SEL fader to bring the FX Return into the main mix.
NOTE: Assumes you have created a main L&R mix and Aux Mix as described.
NOTE: Unassigned faders or faders not assigned to inputs are unlit and have no function
whilst mixing to an FX bus.
MIXING TO MATRIX BUSES
To create a simple mix to Matrix Mix 1:
1. Select fader bank C.
2. Press the MTX1 follow key, notice the faders have
changed colour as they are now your sends from the
buses to Matrix Bus 1 whilst the ON keys are now the routing ON/OFF from the buses to
the Matrix. Also note the SEL key over the MONO/SEL fader is lit and the FaderGlow has
changed colour to orange as this is now the MTX1 Master fader.
3. Raise fader#1 (Mix 1) to send Mix 1 to the Matrix; Note that the Si EXPRESSION has
already SOLOd Matrix 1 for you enabling you to hear it without the need to press any
other keys. To add contribution from the L&R and MONO buses to a matrix mix press the
MTX1 key again; the 3 faders to the left of the fader bank keys now operate as left, right
and mono contributions to the matrix.
4. To control the processing of the Matrix use the controls on the ACS.
a) You may now open the GEQ for Matrix 1 by pressing either the GEQ HI or LO key, close
the GEQ by pressing the lit HI/LO key again.
NOTE: A second press of the active MTX key allows individual contributions to be sent from
left, right and mono buses to Matrix 'n' from faders, 12, 13 & 14 (Expression 1), 20, 21 &
22 (EXPRESSION 2) or 28, 29, 30 (EXPRESSION 3).
NOTE: Assumes you have created a main L&R mix and Aux Mix as described.
NOTE: Unassigned faders or faders not assigned to bus mixes are unlit and have no function
whilst mixing to a matrix bus.
NOTE: If the active mix is stereo the encoder above the fader will act as bus to matrix pan
control (bus to matrix balance if bus is stereo and matrix is stereo).
