Mains Fuse
Under normal circumstance, the mains fuse blows only in the event of failure. When
replacing the fuse, make sure to use a fuse of the same type with identical prearcing
amperage, voltage and blow characteristics. If the mains fuse blows repeatedly, please
contact an authorized service centre.
Mains Socket
Please, make sure to check whether the voltage selector shows the correct mains
voltage that matches the local mains supply at the installation site. An appropriate mains
cord is included in the package.
Caution: This appliance has no user serviceable parts inside. Leave servicing to
a qualifi ed professional.
Voltage Selector

LF-connection cords
Choosing balanced cables (two conductors for audio signals plus separate shielding mesh) is
recommended for LF-signal connection. Although connecting unbalanced cables to the power amplifi er
inputs is possible as well, using balanced cables is always preferable.
A great number of today’s audio appliances provide balanced outputs carried out via XLR-type
connectors. With balanced cabling, the shield interconnects all metal enclosure parts and therefore
effi ciently eliminates the introduction of external interference – mostly noise and hum.
