Panel Descriptions
Front Panel
1 INPUT jacks
Connect your electric guitar or effect unit here. If you’re connecting
a guitar directly, or a monaural effect unit, connect it to the L/
MONO jack. If you connect a stereo-output effect unit to these
jacks, you’ll obtain a stereo effect with the left and right speakers of
the JC-22.
* If you connect your guitar to the R jack, the sound is heard only
from the right speaker.

Turning the Power On/Off
1.
Make sure that the JC-22’s [VOLUME] knob and the
volume of the devices connected to the JC-22 are set to 0.
* Before connecting your instrument to the JC-22’s INPUT jacks,
set the [VOLUME] knob to the minimum setting (far left).
2.
Turn on the JC-22.
* Before turning the unit on/off, always be sure to
turn the volume down. Even with the volume
turned down, you might hear some sound when
switching the unit on/off. However, this is normal
and does not indicate a malfunction.
3.
Turn on the power of the connected devices.
4.
Adjust the volume levels for the devices.
Before switching off the power, lower the volume on each of the
devices in your system and then TURN OFF the devices in the
reverse order to which they were switched on.
* If you need to turn off the power completely, first turn off the
unit, then unplug the power cord from the power outlet. Refer
to “To completely turn off power to the unit, pull out the plug
from the outlet” (p. 2).
