FX device itself. With this application, you will find it very comfortable to control the amp via MIDI and
the ENGL MIDI Interface: All of the amp's MIDI functions can be switched at the same time with the MIDI
FX processor's effects via a MIDI footpedal!
51 SEND
Signal output for the Master Loop or Main Channel 1´s FX Loop (Depending on FX Loop Status
pushbutton (50) setting). Connect this output to a signal processor’s input/return jack via a shielded
cable with 1/4" plugs.
52 RETURN
Signal input for the Master Loop or Main Channel 1´s FX Loop (Depending on FX Loop Status
pushbutton (50) setting). Connect this input to a signal processor’s output/send jack via a shielded cable
with 1/4" plugs.
53 BALANCE
FX mix control for the Master Loop or Main Channel 1´s FX Loop (Depending on FX Loop Status
pushbutton (50) setting): Rotate the knob to the Dry position for the dry amp signal, i.e. no effect on the
signal. Turn clockwise to blend in an effect connected to the loop with the dry signal (parallel/passive).
When the control is set all the way to the Effect position, only the wet signal, i.e. the signal sent from the
FX device, is routed to the power amp (serial/passive).
NOTE:
If you do not connect an effects processor to this loop, set this control to the Dry position!
54 SEND
Signal output for the Main Channel 2´s FX Loop (only active when FX Loop Status pushbutton (50)
setting is set to CH 1/CH 2!). Connect this output to a signal processor’s input/return jack via a shielded
cable with 1/4" plugs.
55 RETURN
Signal input for the Main Channel 2´s FX Loop (only active when FX Loop Status pushbutton (50) setting
is set to CH 1/CH 2!). Connect this input to a signal processor’s output/send jack via a shielded cable with
1/4" plugs.
56 BALANCE
FX mix control for the Master Loop or Main Channel 2´s FX Loop (only active when FX Loop Status
pushbutton (50) setting is set to CH 1/CH 2): Rotate the knob to the Dry position for the pure amp signal,
i.e. no effect on the signal. Turn clockwise to blend in an effect connected to the loop, to the dry signal
(parallel/passive). At the Effect position, only the wet signal, i.e. the signal sent from the FX device is fed
to the power amp (serial/passive).
NOTE:
If you do not connect an effects processor to this loop, set this control to the Dry position!
