16.CH-2 EFFECT LOOP LEVEL Switch
This switch selects the input/output level for the Channel 2
effects loop. Change the switch position to accommodate the
effects device you are using. When the connected unit’s
input/output level is high, set the switch to “+4 dBm,” and
when that level is low, set the switch to “-20 dBm.”
17.CH-2 EFFECT LOOP RETURN Jacks
These are input jacks for the return signal from your effects
device. Stereo connections (L/R) are possible. To use the unit
in mono, use the L (MONO) jack.
* When using this unit in mono, the return sound will not be
output through the speakers even if you input the return sound
to the RETURN R jack. That is, when the L (MONO) jack is
not used, only direct sounds will be output (regardless of the
LOOP switch setting).
* Before you make connections to the RETURN jack(s), be sure to
switch the units off.
18.CH-2 EFFECT LOOP Switch
This switch selects either the series or parallel connection for
the Effects Loop circuit.
When PARALLEL is selected, external effects sounds and
direct sounds (unprocessed sounds) will be mixed.
When SERIES is selected, external effects sounds will not be
mixed with direct sounds.
19.LINE OUT Jacks
Use these jacks to connect the JC-120 to another guitar
amplifier or mixer, or to a tape deck for recording. A stereo
pair (L/R) is provided, but mono connections are also
possible (use the L (MONO) jack).
