9 MIDI THRU
This standard 5-pin DIN port sends incoming MIDI data from the MIDI IN jack to another connected
MIDI device.
10 MIDI IN
This standard 5-pin DIN ports jack receives MIDI data from a MIDI-enabled device such as the
ENGL MIDI Footcontroller. It also providers power to Z-9, Z-12 and Z-15 ENGL MIDI Footcontrollers.
See the next section for more on this.
11 POWER SUPPLY SELECTOR SWITCH
Engage this switch to feed power to an ENGL MIDI Footcontroller via the MIDI cable. When it is set to
position x on the left, the MIDI IN port's pin 1 and pin 2 provide power to the Switcher. If you are using
another make of MIDI footswitch, set the switch to the right to prevent it from being damaged. If this
footswitch is also equipped with a phantom power circuit, refer to its manual to learn which of its terminals
provide power and what its voltage and amperage requirements are. If the voltage and amperage values
match those of the Switcher's phantom power circuit, you can set the switch to the left position to feed
power to the MIDI footswitch via the MIDI cable.
NOTE:
A standard AC power pack provides about 500 mA. The Switcher requires 160 mA maximum; ENGL
MIDI Footcontrollers consume somewhat less than 340 mA. Any other MIDI footswitch that is powered
remotely via the AC power pack may not consume more than 340 mA; otherwise it may overload the power
pack. If you wish to power a MIDI footswitch that consumes more than 340 mA via the Switcher, be sure to
use a power pack that provides sufficient amperage, for example, 1 A.
12 LOOP 1 & 2
Switch Loops 1 and 2 are wired to this stereo 1/4“ jack.
Use button (3) to determine Loop 1's status and button (4) to do the same for Loop 2. These buttons
configure the electrical circuit in one of two ways, open and passive or closed and active.
The figure on the last page
shows the 1/4“ jack's wiring.
13 LOOP 3 & 4
Switch Loops 3 and 4 are wired to this stereo 1/4“ jack.
Use button (5) to determine Loop 3's status and button (6) to do the same for Loop 4. These buttons
configure the electrical circuit in one of two ways, open and passive or closed and active.
The figure on the last page
shows the 1/4“ jack's wiring.
14 LOOP 5 & 6
Switch Loops 5 and 6 are wired to this stereo 1/4“ jack.
Use button (7) to determine Loop 5's status and button (8) to do the same for Loop 6. These buttons
configure the electrical circuit in one of two ways, open and passive or closed and active.
The figure on the last page shows the 1/4“ jack's wiring.
15 SERIAL AMP CONTROL OUT (S.A.C.)
This stereo ¼“ jack sends Serial Amp Control (S.A.C.) data when the configuration of the Switcher's six switch
loops is changed manually using buttons (3 - 8) or by selecting another MIDI memory slot. It lets you control
various channel selection and sound-shaping functions on ENGL amps equipped with a Serial Amp Control
input. Use a ¼“ stereo jack cable to connect this output to the ENGL amp's S.A.C. port.
Note:
The settings of a few functions (FX Loop active, Mid boost active, etc.) on an ENGL amp controlled via
the MIDI Switcher's S.A.C. Out may not match the Z11's Switch Loop settings when you switch the amp on.
The amp and Switch Loop settings will be synchronized as soon as you change a Switch Loop's status
manually or via a MIDI preset.
CAUTION: Connect the Z11 Switcher's S.A.C. Out stereo ¼“ jack to the S.A.C. port of an ENGL Amp only!
Connecting it to any other ¼“ jack may damage the Switcher and the amp!
16 POWER SUPPLY
Plug a suitable AC power pack into this socket to power the MIDI Switcher. The polarity is irrelevant; the
socket handles both AC and DC. The Switcher is ready to operate as soon as adequate power is provided to
this socket. If you are using a switchable universal AC power pack, set it to at least of 9 volts. If you also wish
to power a MIDI footswitch, set it to at least 12 volts.
