REAR PANEL FUNCTIONS
1962 BLUESBREAKER™ REAR PANEL
16. FOOTPEDAL
For connection of the supplied
footswitch to allow 'tremelo' to be
switched on and off.
Note: The 'tremelo' effect will only work
when playing through Channel 2.
17. SPEAKERS
These are for connection to either the
internal speakers and/or an external
speaker load, i.e. extension cabinet(s).
WARNING! Before connecting speakers
please ensure that OUTPUT SELECTOR is
correctly set (Rear Panel Function #18).
18. OUTPUT SELECTOR
WARNING: Your amp should be completely
powered down before the OUTPUT
SELECTOR is turned.
The OUTPUT SELECTOR matches the
amplifier's output to speaker cabinet(s)
impedance.
With all-valve amplifiers it is imperative
that the amp is connected to a speaker
cabinet whilst in operation and that the
impedance selected on the amplifier
matches the total impedance of the
speaker cabinet(s) being used. For
example, if the amp is running into a
single 16 Ohm cab, the amp should
accordingly be set to 16 Ohms. If
running into two 16 Ohm cabs, the amp
should be set to 8 Ohms. If running into
two 8 Ohm cabs, the amp should be set
to 4 Ohms.
WARNING: Failure to comply with these
points may result in damage to the amplifier.
19. H.T. FUSE
The correct value of H.T. fuse is specified
on the rear panel of the amplifier.
20. MAINS INPUT
Your amp is provided with a detachable
mains (power) lead which connects
here. The specific mains input voltage
rating that your amplifier has been built
for is shown on the rear panel. Before
connecting for the first time, please
ensure that your amplifier is compatible
with your electricity supply. If you have
any doubt, please get advice from a
qualified person. Your Marshall dealer will
help in this respect.
21. MAINS FUSE
The correct value of mains fuse is
specified on the rear panel of the
amplifier.
