39 FX LOOP RETURN: LEFT

This is the left channel input for the FX loop. Connect this input to a signal

processor's left output/send jack using a shielded cable equipped with ¼" plugs.

40 FX LOOP SEND

This is the FX loop's output. Connect this output to the input of a signal processor,

or another preamp. ALC automatically adjusts the level of this output to the

different operating modes of the preamp. Use a short shielded cord equipped

with ¼" plugs to connect the preamp.

41 AUXILIARY INPUT

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.

42 P.C. REMOTE CONTROL

You can connect this D-Sub 9-pin port to a personal computer via the serial RS232

interface (Com port). The factory-included software features the Remote Control

Panel; it lets you do just that—control the preamp remotely from your PC.

CAUTION: Connect this port to the serial interface (Com port) of a compatible

personal computer running a Windows* operating system only!

NEVER connect the ENGL Custom Footswitch Z-5 or any other device to this port

because this could damage the preamp's computer system!

* Windows is a registered trademark of Microsoft Corporation.

Note: If you have a live connection between the preamp and a PC, make

absolutely sure you launch the Remote Control Panel on the PC before you switch

on the preamp. Otherwise the preamp may activate Software Download mode,

which could wreak havoc with the internal software of the preamp's main

processor!

43 MIDI OUT

This 5-pin DIN port (diode connector) will only send out MIDI data that the

preamp is programmed to handle. MIDI data is filtered by the internal computer

system, so to speak. For example, say bank A is assigned MIDI channel 01 and

bank B MIDI channel 12. In this case, only MIDI program change commands for

these channels are routed out via the MIDI OUT port. The same holds true for

MIDI volume controller commands.

44 MIDI THRU

Unlike MIDI OUT, this DIN port will forward all incoming MIDI data to any other

connected MIDI device.
