EXP 2 / Footswitch
This menu is to adjust parameters related to external devices
through EXP/FS input.
You need to set up for the type of the external devices. If it is an
external pedal, it is called EXP 2, and you’ll need to manage the
parameters in “Patch Settings – EXP Settings”; if it is a single
footswitch or dual footswitch, the options in the Quick Access
menu will help you set up.
This menu is to set up MIDI messages, including MIDI In Source, Input Channel (DIN), Input Channel (USB), Output
Channel (DIN), Output Channel (USB), Clock Source, Clock Out (DIN) and Clock Out (USB).
MIDI In Source: Control where the MIDI message is coming from.

Output Channel (USB): For setting up the channel of the USB
input and the MIDI messages' input and output
Clock Source: For choosing the source of the MIDI clock.
Clock Out (DIN), Clock Out (USB): To control whether the MIDI
OUT and USB will send out MIDI clock messages. Use this to set
your GP-200 as the main clock for all MIDI devices.

Application Scenarios
17
With full-range speaker devices
Full-range devices include audio interface, studio monitor, PA system, headphones etc. In this scenario, the output jack or
headphone jack of the GP-200 can be connected according to the need of the back-end interface. The balanced and
unbalanced output signals are the same, and the balanced output is more suitable for long-distance signal transmission.
If there is only one speaker, please select the L (MONO) first.
To get the best tonal performance, keep the AMP and CAB modules on and keep the "No CAB" mode o.
In this section, we will introduce the connection methods of GP-200 in common usage scenarios.
With guitar amps (INPUT jack)
In this scenario, directly connect the GP-200's unbalanced output connector to the guitar amp's input connector.
If only one amp is available, please select the L (MONO) first.
To get the best tonal performance, keep the AMP and CAB modules o to avoid adverse eects on the tone.

18
With guitar amps (using FX Loop to pre-position the GP-200)
In this scenario, connect the unbalanced output jacks of the GP-200 to the RETURN jacks of the guitar amp.
This way, by bypassing the preamp and using the power amp to pair with dozens of refined eects in the AMP module,
you’ll get the more realistic sound.
If only one amp is available, please select the L (MONO) first.
To get the best tone performance, keep the CAB module o or turn on the "No CAB" mode to avoid adverse eects on the
tone.
With guitar amps (using FX Loop to post-position the GP-200)
In this scenario, all modules before the AMP (including the AMP module) will be muted, and the eect chain after the
AMP module will be applied between the preamp and the power amp.
In order to get the best tone performance, keep the CAB module o or turn on the "No CAB" mode to avoid adverse
eects on the tone.
In addition, you need to pay attention to the GP-200’s level meter indication, if you hear the “clip” sound, please reduce
the input volume in the "Global - Input/Output”, or adjust the input to Line to try get the more ideal tone.
