CONNECTIONS
POWER
To use the supplied power adaptor, plug the body of the adaptor into a suitable power receptacle.
Then plug the cable into the jack marked “Power” on the Ground Control Pro.
If you have the GCX Guitar Audio Switcher, you don’t need to use the supplied power adapter.
The GCX will phantom power the Ground Control Pro through a standard 5-pin MIDI cable.
Note: If your Ground Control Pro doesn’t power up from the GCX, here’s the problem…
MIDI only requires 3 pins, so to save money some cables only have these 3 pins
wired. Since the GCX uses the 2 unused pins to send phantom power, these cables
won’t work! You need to make sure your cable has all 5 pins wired. Cables with all
5 pins wired are often labeled “5-Pin Active”.
If you are not using the GCX, but have a device that supports phantom power via a 7-pin MIDI
cable, this device can power the Ground Control Pro. Connect the 7-pin MIDI cable from
your Ground Control Pro’s MIDI Out to the 7-pin MIDI In on the device. Then connect the
Ground Control Pro’s Power Adaptor to the phantom power jack on the device.
MIDI
Connect a 5-pin MIDI cable from the Ground Control Pro MIDI OUT to the MIDI IN of your
first device. If you are using the GCX, it should always be your first device.
If you have additional devices, connect the MIDI THRU of the first device to the MIDI IN of
the next device. If the device has no MIDI THRU, then use its MIDI OUT. Continue to chain
your devices until they are all connected.
In some situations you may want to remotely call up presets on your Ground Control Pro, such
as slaving it from a sequencer or having your tech control it from off stage. You can also backup
or edit your presets with a computer. To do this, you’ll need to connect a MIDI cable from the
controlling device’s (computer, another foot controller, etc.) MIDI OUT to the Ground Control
Pro MIDI IN.
EXPRESSION PEDALS
There are two Pedal inputs on the
Ground Control Pro. Any passive
Expression or Volume pedal can
be used. You can tell if your
pedal is passive, because it won’t
use a battery or require any
external power.
The Pedal input jacks take a
standard

" stereo plug. To use a
volume pedal, you need a cable
