REAR PANEL FUNCTIONS

1 & 2. SPEAKER OUTPUTS
Connect one or two speaker cabinets here
using 1/4" jack speaker cables.
Warning:
always ensure the output impedance
selector is set to the appropriate impedance for
the load of your setup (speaker cabinets). Never
use this amp without a speaker or load.
3. OUTPUT IMPEDANCE SELECTOR
Matches the amplifier's output to the load
impedance. Ensure the amp is completely
powered down before turning the selector.
The impedance selected on the amp must
match the total impedance of the speaker
cabinet(s) being used. Common setups include:
• If the amp is running into a single 16Ω cab,
the selector should be set to 16Ω.
• If running into two 16Ω cabs, the selector
should be set to 8Ω.
• If running into two 8Ω cabs, the selector
should be set to 4Ω.
Warning: failure to comply with these points
may result in damage to the amplifier.
4. MAINS SELECTOR
Matches the amplifier mains transformer
voltage to the incoming mains voltage. The
mains selector must be set to the voltage of the
mains supply. Your amp should be completely
powered down before the selector is turned.

Warning: for each voltage setting, the correct
value and type of mains fuse and H.T fuse must
be fitted. Adjustments from 230/220V to 110V
or vice versa will require the mains fuse to be
changed to the corresponding value as detailed
on the rear panel. For more information, please
refer to the Mains Electricity Supply and Output
Impedance section of this guide.
