-> Is the stereo cord defective (say, a short circuit or broken wire)?
Are its plugs' terminal assignments correct?
When powering the Z-9 via an external power unit:
-> Does the external power unit supply the required current and voltage?
(refer to Technical Data on page 17).
-> Is the external power unit or cord defective?
-> Is there a loose connection in the cord's plug?
Does the plug fit snugly in the foot controller's socket?
-> When the Z-9 is powered via an external power unit, a 1/4" plug may not be
inserted in the port.
-> Is the MIDI cord defective (say, a short circuit or broken wire) and does it have
the correct pin assignments (refer to page 18 for pin connections)?
-> Check cable connections: Is the foot controller's connected to the
on the ENGL amp or effect device?
-> Is the amp or MIDI effect device set to MIDI channel 1?
To check this, you can set the amp (or effect device) to OMNI Receive mode.
In this mode, MIDI data are received via all 16 channels.
-> Is the connected MIDI device able to switch to the selected MIDI patch?
The number of MIDI patches on the MIDI device may be limited
(look this up in the MIDI device's operating manual).
-> Is your ENGL amp or ENGL MIDI peripheral device equipped with a display
providing visual confirmation?
If not (as is the case with the E670 and Z-7), perhaps you have not programmed
different settings (presets) to the MIDI patches. This may explain why there is no
response when you select presets. Program presets with different settings and
try again.
-> Is a plug inserted into the two-way footswitch jack of the ENGL device?
When you plug in a two-way footswitch, the channel switching option on the
amp/preamp/poweramp is disabled, as are the S.A.C. and MIDI remote control
options.
Choose one remote control option - S.A.C., MIDI two-way footswitch. Do not
combine these operating modes!
-> Check the cord connecting the amp and Z-9 for a short circuit or broken wire.
-> Is the cord leading from the amp inserted in the right jack (S.A.C. Port)?
-> Try switching functions manually on the amp to see if it responds.
-> Is a plug inserted in the two-way footswitch jack at the amp?
Connecting a two-way footswitch disables the channel switching option, as well
as the S.A.C. and MIDI remote control options.
Do not combine remote control options! Opt for S.A.C., MIDI
the two-way footswitch.
