BACK PANEL:
WARNING: This amplier must be earthed. Please check that the supply voltage details given on the
rating label (located on the rear panel) are in accordance with your electricity supply.
1 EXTERNAL SPEAKER OUTPUT : This is a 1/4” output jack with which you can connect an external
speaker cabinet, if desired. This output is adapted for an 4 Ohm impedance load. The external
speaker must therefore have a minimum impedance of 4 Ohms.
Under no circumstances should you connect a speaker cabinet with impedance under 4 Ohms, as
this can severely damage your amplier. A 8 Ohm cabinet will present no danger, though the full
power of the amplier will be slightly compromised. Always use a suitable speaker cable and NOT a
guitar cable when connecting external speakers.
2 MAINS INPUT: This is the input socket into which the mains power cable must be connected. This
amplier is supplied with a power cable with a moulded-on plug. If the socket outlets in the home are not
suitable for this plug, use an appropriate plug adapter that can handle the power required for the amplier.
3 POWER FUSE: In the event of the power fuse having to be replaced, rst unplug the power cable from the
mains outlet. Then remove the fuse cover and replace the power fuse with another fuse of the same type
and value. Never plug the power cable back into the mains outlet without the fuse cover. If the power fuse
blows up again when powering on the amplier, take the apparatus to a suitable service centre for repair,
please contact your local dealer.
