Rear Panel
1. Mains Input
The supplied detachable mains lead is connected here. The lead should only
be connected to a power outlet that is compatible with the voltage, power and
frequency requirements stated on the rear panel. If in doubt get advice from a
qualified technician.
2. Mains Fuse
The value of the Mains Fuse is specified on the rear panel. Never use a fuse of the
incorrect value or attempt to bypass it.
3. H.T. Fuse
The value of the H.T. Fuse is specified on the rear panel. Never use a fuse of the
incorrect value or attempt to bypass it.
4. Impedance Selector
This control matches the amplifier's impedance to that of the connected speakers.
Always ensure that the selected impedance matches that of the speaker cabinets
connected. See table below.
Cabinets Connected
1 x 16 Ohm cabinet
2 x 16 Ohm cabinets
1 x 8 Ohm cabinet
2 x 8 Ohm cabinets
1 x 4 Ohm cabinet
A speaker cabinet of less than 4 Ohms, or 2 x 4 Ohm cabinets, should not be used
together with this amplifier.
WARNING: The amplifier must always be completely powered down before
adjusting the setting of the Impedance Selector. Failure to do this, or to correctly
match the impedance of the amplifier and speakers, will damage the amplifier.
5. Speaker Outputs
There are two parallel speaker outputs for connecting external speaker cabinet(s).
When connecting speakers always ensure that the Impedance Selector (4) is set
correctly.
