WARNING! Never turn on or use the amplifier without a load or speaker connected to the amplifier.
ALWAYS use a good quality (non-shielded) speaker cable. Never use (shielded) instrument cable.
ALWAYS match the amplifier’s speaker output impedance to the impedance of the speaker
that is being used. Use only one type impedance output at a time. If more than one speaker is
connected at the same time, make sure they all have the same impedance rating. Never use
two or more cabinets with different impedance ratings. This will create an unbalanced load.
When using multiple speaker cabinets (with the same impedance rating), match the total load
impedance of the speaker cabinets to the speaker output of the amplifier.

8. AC POWER INPUT WITH MAINS FUSE
ASSEMBLY: The amplifier is equipped
with a detachable power cable that plugs
into the IEC Mains socket on the back of
the amplifier. The AC power cord should
only be plugged into a grounded power
outlet that meets all applicable electrical
codes and is compatible with the
voltage, power, and frequency
requirements stated on the rear
panel of the amplifier.
Do not attempt to defeat the safety
ground connection.
The AC Mains fuse is located in the IEC
Mains socket and is used to protect the
amplifier from electrical faults. If the fuse
needs to be replaced, please refer to
the correct fuse specifications located
on the back panel of the amplifier.
Never bypass the fuse or replace it with
a wrong type or value.
