enabled foot board is a custom design that switches every preamp 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 is disabled when the Z-9
Footswitch is connected.
Connect only the ENGL Z-9 Footswitch to this 6.3 mm (1/4") stereo jack!
Connecting any other switching device may damage it and/or the preamp's circuitry!
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 and As an
alternative to the option, you can opt to control any other switchable
preamp functions, for example , , etc. 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 preamp via a proprietary ENGL serial data protocol, and the Serial
Amp Control Port was developed exclusively for ENGL amps. No other foot board will
work and in fact is likely to damage the foot board or preamp's circuitry!
Use this jack to connect a conventional footswitch with two switching functions (for
example, the ENGL Z-4) that let you access the four channels , , and
. One of the two switches activates Main Channel 1 and 2, while the other
activates the selected Main Channel's two subordinate channels, and or
and , as the case may be. The onboard channel switching facility, to
include switching, is disabled when you plug a footswitch into this jack.
A footswitch may be equipped with LEDs indicating the given switching
status. Each of the two switches is provided with 15 milliamperes current, which
suffices to power a standard LED.
The jack's mono terminal selects the Main Channel, while the stereo terminal selects
the sub channel (refer to Pin Assignments on page 30).
