L. AC Inlet
Connect the supplied power cord here.
* For details on the power consumption, refer to p. 162.
The unit should be connected to a power source only of the type marked on the side of
unit.
M. 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)
