About Functional Ground 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, mics connected to it, or the metal portions of other objects.
This is due to an in nitesimal electrical charge, which is absolutely harmless. However, if you are concerned about this,
connect the ground terminal (see gure) 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 re or explosion)
