SUB OUT jacks
You can connect speakers here for use as monitors, or for outputting only the reverb
sound. The system setting "Output Assign" (p. 75) specifies which sounds will be output
from the SUB OUT jacks.
* The [VOLUME] knob on the top panel does not adjust the volume of these jacks.
AUDIO IN (STEREO) jack
Connect your digital audio player or audio playback
device here. Use a stereo mini-plug cable (commercially
available) to make the connection.
The input level is adjusted by the [LEVEL] knob
located at the left of the jack.
PHONES jack
You can connect a set of headphones (sold separately)
here.
* When connection cables with resistors are used, the volume level of equipment connected to the AUDIO IN jack may be low. If this happens, use
connection cables that do not contain resistors.
MAIN OUT (TRS) jacks
Connect your speakers here. To employ monaural output, connect to the L/MONO
jack.
[POWER] switch
Turns the power on/off (p. 31).
DC IN jack/Cord hook
Connect the included AC adaptor here.
Cord Hook
The cord of
the supplied
AC Adaptor
* To prevent the inadvertent disruption of power to your unit (should the
plug be pulled out accidentally), and to avoid applying undue stress to
the DC IN jack, anchor the power cord using the cord hook, as shown in
the illustration.
* Place the AC adaptor so the side with the indicator (see illustration)
faces upwards and the side with textual information faces downwards.
The indicator will light when you plug the AC adaptor into an AC outlet.
Panel Descriptions

Ground terminal
Depending on the conditions of your setup, you may
experience a slight tingling sensation when you touch
a metal component of the JUPITER-50. This is due to
an infinitesimal electrical charge, which is absolutely
harmless. However, if you are concerned about this,
connect the ground terminal (see figure) with an external
ground. When the unit is grounded, a slight hum may
occur, depending on the particulars of your installation.
If you are unsure of the connection method, contact the
nearest Roland Service Center, or an authorized Roland
distributor, as listed on the "Information" page.
Unsuitable places for connection
• Water pipes (may result in shock or
electrocution)
• Gas pipes (may result in fire or explosion)
• Telephone-line ground or lightning rod (may
be dangerous in the event of lightning)
