Connecting the 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 AC adaptor jack, anchor the power cord
using the cord hook, as shown in the illustration.
AC adaptor
(included)
Place the AC adaptor so the side with the indicator (see illustra-
tion) faces upwards and the side with textual information faces
downwards. The indicator will light when you plug the AC adaptor
into an AC outlet.
About the Grounding Terminal
Depending on the circumstances of a particular setup, you may
experience a discomforting sensation, or perceive that the surface
feels gritty to the touch when you touch this device, microphones
connected to it, or the metal portions of other objects. 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)
