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.
