MAINS INPUT & FUSE
The specific mains input voltage rating that your
amp has been manufactured for is indicated on
the rear panel of the amp. Your amp is provided
with a detachable mains (power) lead, which
should be connected to the mains input socket
on the rear panel of the amp. The correct value
and type of mains fuse is specified on the rear
panel of the amp.
Never attempt to bypass the fuse or fit one of
the incorrect value or type.
IMPORTANT SET UP INFORMATION
1. When using your amp with one or more
speaker cabinets, make sure that they are
connected to the correct loudspeaker jack
sockets.
Warning: failure to do the above may damage
your amp. When connecting a speaker cabinet
make sure that you use a proper speaker cable.
Never use a screened (shielded) guitar cable for
this purpose.
2. Ensure that the power switch is set to the
off position and the standby switch is set to
standby.
3. Connect the supplied mains (power) lead
into the mains input on the rear panel first
and then into an electricity outlet.

output level controls on the front panel are
