Overview
The GCX Guitar Audio Switcher greatly expands the capabilities of your
Ground Control foot controller. With the GCX, you can select pedal effects,
signal processors, multiple amps or preamps, amp channels and more.
The GCX has two 1/4 inch feed thru's from front to back. The feed thru
labeled "
GUITAR IN" is buffered to maximize guitar pickup tone quality,
minimize noise, and allow signal splitting to drive multiple devices. The one
labeled "
FEED THRU" is passive and can also be used from back to front as an
amp out.
The GCX has eight audio loops, each with separate IN, OUT, SEND and
RETURN jacks. They can switch effects in and out, A/B select or mute sends
for parallel effects systems, all at either instrument or line level. In addition,
loops can be used as latched or momentary switches.
Your GCX will phantom power both the Ground Control and Ground Link
foot controllers using a standard 5-pin MIDI cable.
