operation.
AC Mains voltage selector:
Set this switch to the appropriate position to match the mains voltage in the country in
which you are using the amplifier. WARNING: Do not adjust this control with the AC

switch is set to the wrong position. If you have any doubts as to which is the correct
voltage for the country you are in, call the factory or inquire with someone locally who will
know the correct mains voltage.
HT Fuse:
500mA fast-acting fuse
Impedance Selector:
The impedance selector allows selection of 4, 8, or 16 ohm output impedance to match
the speaker in use. Be sure to set this switch to the appropriate setting for the speaker or
speakers connected to the amplifier.
single 16-ohm speaker or a pair of speakers wired in series to provide a 16-ohm load.
This allows connection of an external 16 ohm cabinet to be used simultaneously with the
internal speaker by setting the impedance selector to 8 ohms, or four 16-ohm cabinets
can be used by setting the impedance selector to 4 ohms.
Speaker Jacks:
Two speaker jacks are provided to allow use of the amplifier with either the internal
speaker (combo units only) or up to two external speaker cabinets. More than two
external cabinets may be safely used with the amplifier, but this will require the use of "Y"
cables for the extra two cabinet connections. Be sure to use only quality speaker cable -
do NOT, under any circumstance, use guitar cable to connect the amplifier to a speaker
cabinet. Doing so may cause damage to the amplifier.
