You can use the device as a conventional switcher with six switch loops, as a MIDI-to-S.A.C. control unit (for ENGL amps only), and even as a MIDI switching center for two ENGL amps, addressing one amp like a conventional switcher and the other via the S.A.C. Out circuit. This comes in very handy when you want to do things like control two Powerball amps in parallel and simultaneously via MIDI.
Changing Loop 1's status also triggers an S.A.C. message in serial data format that is sent to the S.A.C. Out (15) port. For Loop 1 this S.A.C. command lets you control a given ENGL amp function – for example Channel Up/Down on the Powerball-2 – directly via the S.A.C. port.
11 POWER SUPPLY SELECTOR SWITCH Engage this switch to feed power to an ENGL MIDI Footcontroller via the MIDI cable. When it is set to position x on the left, the MIDI IN port's pin 1 and pin 2 provide power to the Switcher. If you are using another make of MIDI footswitch, set the switch to the right to prevent it from being damaged.
You have another remote-control option for ENGL amps alongside the six switch loops: Simply connect your ENGL amp that is equipped with a S.A.C. Port to the S.A.C. Out (15) port to send MIDI messages via the S.A.C. interface. This lets you do things like switch two ENGL Powerball-2 amps or an early Powerball version and a later Powerball-2 version in parallel via MIDI.
If you need to check the wiring, you'll find the scheme for the 1/4“ stereo jacks pictured on the last page. -> If you are dealing with an amp other than ENGL, is it designed to respond to a simple on/off electrical circuit controlled by a single-pole, single-throw switch? If you are unsure, contact your local authorized service center or consult a professional.

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!
Power supply: Via an external 12-volt DC or 12-volt AC power pack with approx. 500 mA current Switcher's max. power consumption: approx. 160 mA, all Switch Loops active. Switchable phantom power for ENGL MIDI footcontrollers via MIDI cable; see table below for pin assignments. System: Controller AT89S52 with internal 8k FLASH memory for software, 12 MHz system clock;...
