Panel Descriptions
9 AC IN jack
Connect the included power cord.
* Use only the power cord that was included with the unit.
10 PHONES jack
Connect headphones here.
* If a plug is inserted in this jack, no sound will be output from the
JC-40’s own speaker.
11 LINE OUT jacks
Connect these to your PA system or recorder.
You can use this in conjunction with an external PA system, or to
record your performance via direct line while monitoring the sound
from the JC-40’s speaker.
If you’re using a monaural connection, connect your equipment to
the L/MONO jack.
* If chorus is on and you connect the line out in stereo, the
dimensional space chorus effect (L: direct sound, R: effect
sound) is obtained.
12 EFFECT LOOP SEND/RETURN jacks
Connect an external effect device.
Connect the SEND jack to the input of your external effect device,
and connect the output of your external effect device to the
RETURN jack.
If you connect a stereo effect unit, the stereo effect is obtained
using the JC-40’s left and right speakers. If you’re connecting a
monaural effect unit, connect it to the L/MONO jack.
* If you connect only the R jack, sound is not output from the
speakers, the LINE OUT jacks, and the PHONES jack.
* The sound that is input from the RETURN jacks is not affected by
front panel controls 2 – 5 . If you want controls 2 – 5 to affect
this sound, connect your equipment to the front panel INPUT
(L/MONO, R) jacks.
* Make connections after first checking the wiring diagrams of
other equipment you intend to connect. To prevent malfunction
and equipment failure, always turn down the volume, and turn
off all the units before making any connections.
[LOOP] switch
When “PARALLEL” is set, the external effects sound and the direct
sound are mixed.
When “SERIES” is set, only the external effects sound is played.
* When “SERIES” is set, there will be no sound if the volume of your
external effect device is turned down or if it is powered-off.
& For details on the EFFECT LOOP SEND/RETURN jacks and the
[LOOP] switch, refer to “Block Diagram” at the end of this manual.
13 FOOT SWITCH jacks
If a separately sold footswitch (BOSS FS-5L, FS-6, FS-7) is connected,
you can turn chorus/vibrato, reverb, and distortion on/off with your
foot.
* The JC-40 is compatible with latch-type footswitches
(FS-5L, FS-6, FS-7). If you’re using an FS-6 or FS-7, set the mode
of A and B to FS-5L (LATCH).
* If you’re using an FS-6 or FS-7, connect a 1/4” plug (monaural) to
jack A or B.
* If you’re using the A&B jack of the FS-6, use a stereo 1/4” plug
, two 1/4” monaural plugs (sold separately: PCS-31L, etc.).
