Please read and heed:
Connect the left FX Loop input to a signal processor's left channel output/send jack
using the shortest possible shielded cord equipped with 1/4" plugs. Activate and
deactivate it via the Stereo FX Loop (17) button. In the signal path, the
is located post channel Volume controls and and pre the Master control and the
output driver stage.
Connect this output to a signal processor's input/return jack using the
shortest possible shielded cord equipped with 1/4" plugs. Activate and deactivate it via
the FX Loop Active (17) button. In the signal path, the is located post
channel Volume controls and pre the Master control and the output driver stage.
This is the preamp's ancillary input. The circuit is wired in series with the input located
on the front panel. Use it to connect the preamp to a 19" rack setup. The front panel
input has priority. In other words, when you insert a plug into the front panel jack (1),
the signal routed in via the Aux. Input is cut off.
This 5-pin DIN port patches incoming MIDI data from the (55) to any other
connected MIDI device.
This 5-pin DIN port accepts data sent by a MIDI sender (for example, the ENGL MIDI
Z-12, Z-15, or Z-9 foot controllers) or from or routed through another MIDI device.
Switch no. 56 lets you activate the preamp's power supply if you have an ENGL MIDI
foot controller connected to this port.
Before you connect any other MIDI footswitch or effects device, always
make sure that switch no. 56 is set to the right to avoid damaging the device.
This selector activates a MIDI In port power supply for connected ENGL MIDI foot
boards. Power is fed to the board via the MIDI circuit. When the switch is set to the left
position, power is routed to the MIDI In port's pin 1 and pin 2 (refer to page 30 for pin
assignments). If you choose to use another MIDI foot board, be sure to set the switch
to the right to avoid damaging it. If the foot board you are using is designed to handle
phantom power, consult its operating manual to learn how it is wired (that is, which
pins carry its power supply) and what its voltage and current specifications are. If the
voltage and current specifications and wiring match, you may set the switch to the left
to power this foot board via the MIDI cable.
Note that a MIDI foot board may not draw more than 200
milliamperes of current if you want to power it via this port. You must also check and
verify if this MIDI foot board is able to handle 11 volts of alternating current (AC)! If
you are in any doubt, be sure to consult a specialist, meaning an amp technician or
electronics engineer who earns a living with a screwdriver!
