4.2 Using With a Switching System
Switching systems, such as the Digital Music GCX Guitar Audio Switcher, can be used to
connect/disconnect the amp signal from the input of the effects. By muting the
input
of the
effect, not the
output,
effects like delays and reverbs will trail off gradually. This means the last
delayed notes of your solo can linger on as you start to play rhythm again. There are many
benefits and uses of this type of smooth transition.
The following examples show how to use the GCX with the System Mix. For simplicity's sake,
they show how the GCX would be added to the same systems described above.
System #1 + GCX Loops
This example uses two GCX loops to switch the inputs of the two effects devices.
1. The guitar is connected to the amp or preamp input. The preamp output or amp effect send is
connected to the Left input of Mix 1 In 1.
3. The stereo outputs of the effects are brought back to the mixer to be blended with the original
preamp tone using In 2 and In 3 of Mix 2. Mix 2 In 1 is being used by the internal connection
with Mix 1 (the preamp). Next, the Mix 2 Outputs are connected to the power amp input, or
the amp effect return.
In this example, the Mix 1 knob controls the level of the preamp, and the Mix 2 knob controls the
level of the entire mix. Please refer to Section 3.3 to correctly set levels.
2. The passive split sends copies of the
preamp signal to the inputs of two
different GCX loops instead of going
directly to the inputs of the effects
devices. Next, the Send of each GCX
loop is connected to effect inputs.
When the loops are on, the signals pass
through. When the loops are off, the
sends to the effects are muted.
