Practical examples: the ENGL Z11-S.A.C. used as a MIDI Switcher
and as a MIDI-to-S.A.C. interface for ENGL Powerball amps
Some more hot tips:
The Switcher also lets you combine a later Powerball-2 version with an earlier Powerball-1 version.
The S.A.C. interface controls the Powerball-2 amp; four switch loops control the older version of the E645.
You can also combine two Switchers in a MIDI setup to store different settings for two Powerball-2 amps in
one MIDI memory slot, for example, to activate the FX Loop and select the Crunch channel on amp #1, and
to deactivate the FX Loop and select the Lead channel on amp #2.
What's more, you can use the Switcher to remote-control other ENGL amps equipped with an S.A.C. Port
and/or footswitch inputs via MIDI, for example, the Gig Master Amp, Raider 100 Combo, and more.
You do not need the Switcher for ENGL amps that are equipped with an S.A.C. port and a MIDI Input.
Also, these amps' functions cannot be controlled via the S.A.C. interface using the Switcher!

In this scenario, the Switcher serves
as a MIDI-to-S.A.C. interface to control
an ENGL Powerball-2 amp.
Connections:
Use a stereo ¼ ” jack cable
to connect the amp's S.A.C. Port (1A)
to the Switcher's S.A.C. Out (1S).
These functions on the Powerball 2
are MIDI-switchable:

Example 2:
In this scenario, the Switcher serves
as a MIDI-to-S.A.C. interface and as
MIDI Switcher to control
two ENGL Powerball-2 amps
simultaneously and in parallel.
Connections:
Use a stereo ¼ ” jack cable to connect
amp #1's S.A.C. Port (1A) to the Switcher's
S.A.C. Out (1S). Use three
stereo 1/4“ jack cables to connect
amp #2's footswitch jacks (2A, 3A, 4A)
to the Switcher's switch loop jacks (2S, 3S, 4S).
These functions on both Powerball-2 amps
are MIDI-switchable:
