Operating Instructions: MIDI-Footcontroller Z-12: page 2
8 MIDI OUTPUT Port at the Footcontroller's side panel:
Standard 5-pin diode jack for connecting the MIDI cable. Connect this output to the MIDI IN jack of a MIDI device. As an alternative
to the power supply socket (9), you can route the power supply (see Table for voltage specifications) via Pin 1 and Pin 2
(center) of the MIDI cable. To supply the power to the footcontroller use a 5 pole diode cable.
9 POWER SUPPLY socket - Foot controller power circuit:
If you do not route the power supply via the MIDI cable, you must connect an external power pack here. You can use standard power
packs that supply either 9-20 volts DC or 7-15 volts AC and approx. 300 mA current. Ensure the power pack you choose bears the
requisite safety certification. The polarity of the socket is insignificant.
10 Two-increment, 7-Segment LED Display.
This display inidcates the selected MIDI Program Location. When you change banks, the right position flashes until you press a
Program Location button to activate a new Program or return to the original bank. The right decimal point indicates Program
Locations higher than 100 by illuminating continually. If the decimal point flashes, the Footcontroller is in Channel Selection mode
and the Channel Number (01 -16) appears in the display.
After you power the Footcontroller up, the ENGL logo runs across the display until you press a button.
11 Program Location Number 9" Button.
When you press this button, the Footcontroller sends MIDI Program Locations 09, 19, 29, ... to 119 in the respective bank. In the
last bank (120 to 128), this button is inactive. In other words, if you press it while this bank is active, no Program Change message
is sent and a dash appears in the right position of the 7-segment display.
12 "Program location Number 8" Button:
When you press this button, the Footcontroller sends MIDI Program Location 08, 18, 28... to 128 in the respective bank.
13 "Program location Number 7" Button:
When you press this button, the Footcontroller sends MIDI Program Location 07, 17, 27... to 127 in the respective bank.
14."Program location Number 6" Button:
When you press this button, the Footcontroller sends MIDI Program Location 06, 16, 26... to 126 in the respective bank.
15 "Program location Number 5" Bu
t
ton:
When you press this button, the Footcontroller sends MIDI Program Location 05, 15, 25... to 125 in the respective bank.
