Roland JC-120 Attaching/Removing Caster Wheels

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).

Switching On Power

*Turn on power to your various devices in the order specified. By

turning on devices in the wrong order, you risk causing

malfunction and/or damage to speakers and other devices.

Switch on the power on all devices EXCEPT the device(s)

connected to the LINE OUT jacks (19).

Turn on the JC-120’s power.

Finally, switch on the power on any devices connected to

the LINE OUT jacks.
