Introducing the R-4
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)
