1. Use a dual footswitch such as the ENGL Z-4, connecting it to the amp via a stereo cord equipped 
with ¼" jack plugs. 

You can switch channels and 

Mid Shape 

via the dual footswitch connected 

to port 18, 

Reverb Off/On

 and 

FX Loop off/on

 via the dual footswitch connected to port 17.

2. Use a MIDI switcher such as the ENGL Z11-S.A.C., connecting it to the amp via two stereo cords 
equipped with ¼" jack plugs. 

The buttons on the switcher can serve to control 

Clean/Lead

Mid 

Shape

Reverb 

and 

FX Loop

. You can also program all kinds of switching setups to the various MIDI 

program locations. Here's just one example: You could configure MIDI Preset #1 so that the Clean 
channel and 

Reverb

 are on, while 

Mid Shape

 and 

M.V.B.

, are off. Then you could set MIDI Preset #2 up 

so that Lead channel, 

Mid Shape

, and 

FX Loop

 are on, while 

Reverb

 is off.  

Whatever setups you decide to program, you can easily activate the desired configuration directly 
via a MIDI board such as the ENGL Z-9, Z-12, or Z-15. 
This type of control option is extremely versatile; we recommend it highly if you intend to use
the amp in conjunction with any MIDI system, including MIDI effects devices.
