also use headphones simultaneously.
Input Jacks

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. 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.
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)
