MIDI SWITCHER Z11-S.A.C.
The Z11 S.A.C. MIDI Switcher serves to switch certain functions of amps via MIDI. It works with all ENGL amps that are not equipped with MIDI interfaces, for example the Powerball 100, Thunder 50, Screamer, and E530 19" rack preamp models, as well as most other amps equipped with 1/4" jack plugs that accept single-pole, single-throw (SPST) footswitches.
2 MIDI CHANNEL Use these DIP switches to set the MIDI channels to OMNI or POLY 1 through 8 to enable MIDI data reception. The table below shows the DIP switch settings for the respective channels. You'll find the same table on the Switcher's top panel.

Setup and Installation: You have several setup and installation options: 1. To set the Switcher on a flat surface, first stick the four adhesive rubber pads to the bottom of the device. 2. Attach it to your ENGL device using the velcro strips, for instance, to the Powerball's rear panel or inside the speaker cabinet area of a combo's housing. 3. To install it in a 19" rack, attach the optional rack-mount panel to the Switcher's front face using four screws. Connections: 1.
Troubleshooting * The MIDI Switcher fails to respond. It will not power up even though you have connected its power pack to an AC outlet. The Status LED above the WRITE button is not flashing, and you are unable to activate any of the switch loops. -> Is the power pack providing the necessary voltage and sufficient amperage? (See Technical Data for specifications.
