Mace, ευχαριστώ για την απάντηση!
Άρα μήπως, εννοεί εδώ στο 3. ότι το Ζ11 η/και το Ζ12 λειτουργεί σαν footswitch απλό με δυνατότητα ελέγχου κι άλλων midi συσκευών (αν υπάρχουν)
Από το manual:
The different options for controlling the Screamer 50 amp remotely:
1. ENGL Custom Footswitch Z-5: Connect it to the "Custom Footswitch Port" (19) port via a
9-pin computer cable. Functions: Direct access to Clean (Clean & Lo Gain), Crunch (Clean & Hi Gain),
Soft Lead (Lead & Lo Gain), Heavy Lead (Lead & Hi Gain) as well as V.L.S. and Reverb. This is a very
convenient yet compact solution.
2. Dual footswitch (e.g. ENGL Z-4): Connect it to the amp via a stereo ¼" cord. You will need
one dual footswitch for switching channels via Jack 20 and another footswitch for switching
V.L.S. and Reverb via Jack 21. Functions: Clean/Lead, Gain Lo/Hi, V.L.S., Reverb. With this solution,
you can't activate the channels Crunch and Heavy Lead directly, i.e. this requires an intermediate
switching operation.
3. MIDI-Switcher (e.g. ENGL Z-11): Connect the board to the amp via two stereo ¼" cords. The
buttons on the Switcher control Clean/Lead, Gain Lo/Hi, V.L.S. and Reverb. If you program the diverse
switching configurations to different MIDI program locations (e.g. Gain Hi & Lead & Master Lo &
Reverb), you can activate the desired configuration directly via a MIDI board (e.g. ENGL Z-12).
This type of control option is extremely versatile, we recommend it highly if you intend to use the
amp in conjunction with a MIDI system (e.g. MIDI effects devices).
