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 "...

(passing from the back to the front). You can also use it as an instrument input if you do not wish to use the buffer. Using at least one feed thru ties audio ground to the GCX chassis. This allows the GCX chassis to act as a noise shield for the audio loops and circuitry.

FEED THRU Example 3. Splitting to more than two devices using Y-cables: Because GCX feed thru's have low impedance outputs, you can drive multiple devices from each output. In this example, the guitar signal passes to all four devices using two Y-cables.
Effects Loops The basic function of a GCX loop is to switch effects in and out of the signal path. In this example, when the loop is ON, the pedal is active. When the loop is OFF, the pedal is bypassed.
A/B Switching GCX loops can be used for A/B switching. The following are two examples. Example 1. Selecting between two preamps: When the loop is OFF, Preamp-1 feeds the audio out. When the loop is ON, Preamp-2 is selected. Example 2. Selecting between two amps: When the loop is OFF, Amp-1 plays.
Combining Multiple Amps By using multiple loops, combining amps is possible. When loop #1 is ON and loop #2 is OFF, only Amp-1 is active. With loop #1 OFF and loop #2 ON, only Amp-2 is active. When both loops are ON, both amps play at the same time.
Using Loops as Switches ________________________________________________________ GCX loops will act as footswitches like those used for amp channel switching and bypassing signal processors. The GCX supports both standard switch types, latched and momentary. You can also select between normally open and normally closed operation.
For example, let's say you're controlling reverb on your amp from its footswitch input, but the GCX status LED is ON when the reverb is OFF. You can fix this by changing from normally open to normally closed (plug into the SEND/N.C.
Setup Mode In Setup Mode, you will first tell the Ground Control that it is connected to a GCX, and then specify how each GCX loop should function. Here's how: D I G I T A L M U S I C C O R P O R A T I O N...
This indicates that the Ground Control and GCX are successfully communicating. Controlling GCX Loops Now that you have setup your Ground Control to access the GCX, you can easily control each of the eight loops. 1. Press [SELECT ] until the Ground Control display reads "GCX-1".
If you have any questions about this, please contact Digital Music Corporation's customer service department. It is possible to control the GCX from other devices like MIDI sequencers, some MIDI footpedals, or any device capable of transmitting MIDI Control Change messages.
