Connections
* Before making connections, be sure to turn down the volume on your
amp and turn off all power. Making connections with the power on
may cause problems.
* if your amp/speaker system is monaural, connect it to the (МОМО)
jack.
(Guitar Connections)
Connect the output of your guitar to the INPUT jack.
* INPUT jacks for your guitar are provided on the front panel and also
on the rear panel. If both are connected, only the INPUT jack on the
front panel will function.
(Power Amp Connections)
Connect your power amp to the outputs of the GP-100.
With the GP-100, the connections you need to make will depend
on the number of amps you have and other factors in your setup.
Select the connection method that is appropriate to your situation.
* If you will be outputting in monaural, connect your power amp to the
L (MONO) jack.
* If you will be outputting in stereo, connect your two amps to the L and
R jacks of the same output pair (A or B).
