MIDI commands (HEX: Bn). To enable MIDI control, you must set small switch labeled
'6' on the larger piano DIP switch (46) to ON. See page 20 for details on how to do this.

47 Footswitch: Serial Amp Control Port
This serial data input accepts the Custom ENGL Z-9 Footswitch (optional), which lets
you control various amp functions remotely. Connect the Z-9 Footswitch to the amp
port using a cord equipped with stereo ¼" jack plugs. This MIDI-enabled foot board is a
custom design that switches every amp feature designated as footswitchable in this
manual. To learn if a given feature may be controlled remotely, refer to its description
herein. The MIDI In port (44) is disabled when the Z-9 Footswitch is connected. A
configuration table for assigning the ENGL INVADER's sound-shaping and special
functions to the Z-9 Custom Footswitch's buttons is printed on page 38
Connect only the ENGL Z-9 Footswitch to this (1/4") stereo jack! Connecting
CAUTION:
any other switching device may damage it and/or the amp's circuitry!
Insert and remove the Z-9's cable to and from the S.A.C. Port only when the amp is
switched off!
A tip from the designer:
The Custom Z-9 Footswitch was designed with the non-MIDI guitarist in mind. It's sure
to delight if you don't or won't use MIDI systems. Based on a rather nifty switching
concept, it provides direct access to the four channels. It also lets you control any other
two switchable amp functions, for example,
Another tremendous benefit of this microcontroller-driven foot board is that it
connects to the amp via an easily obtained, standard stereo cord. But that's not the last
of the Z-9's advantages: At some point, you may decide to ramp up or connect to a
MIDI system. This won't render the Z-9 obsolete because it also serves as a simple MIDI
foot board with a MIDI OUT (5-pin DIN connector) that selects 10 MIDI patches (or
presets, if you prefer). Again, I want to emphasize that you should never connect
another foot board to this jack: The Z-9 controls the amp via a proprietary ENGL serial
data protocol, and the
amps. No other foot board will work and in fact is likely to damage the foot board or
amp's circuitry!
