Below the FX model controls are the FX Unit controls which are independent of the
FX model being used.
FX Unit Mode – ‘Shared’ allows multiple channels to send signal to the FX Unit
simultaneously, and for the output of the FX Unit to be sent to Main LR, Outputs or
other FX Units at different levels using either the PROCESSING / SENDS screen, or
the FADER screen. Shared mode is generally used for reverbs and delays.
‘Inserted’ allows the FX Unit to be used in a single input or output channel, to use a
Chorus on a violin for example.
FX Send Level – Adjust the overall level of signal coming into the FX Unit. This is
the same control as the fader on the right-hand side of the FADER screen when
this FX Unit is selected from ‘Sends to’.
FX Level to LR – Adjust the send level of the FX to the Main LR.
Mute Mode – Set Trails On to hear any reverb or delay trail fade out naturally when
muting an FX unit. Set Trails Off to have the FX mute instantly.
MUTE – Mute or unmute the selected FX Unit.
