Names of things and what they do
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, such as guitars. 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)
* You must make the ground connection using the screw that came with the PC-80.

want to use bus power, set the power switch to the USB position.
With some computers, the PC-80 may not operate on bus power. If so, please use
the included AC adaptor.
