About Ground Terminal

In some cases, depending on the environment in which the unit is installed, the surface of the panel may sometimes feel rough and grainy. This is due to an infinitesimal electrical charge, which is absolutely harmless. However, if you are concerned about this, connect ground terminal (see figure) with an external ground. When the unit is grounded, a slight noise may result, depending on the particulars of your installation. If you are unsure of the connection method, contact nearest Edirol Service Center, or authorized Edirol/Roland distributor, as listed on the “Information” page.
