Please read this manual carefully before plugging in. Follow all instructions and heed all
warnings.
Warning: please refer to full details in separate
Important Safety Instructions leaflet
(document number CATS-00158).
MAINS ELECTRICITY SUPPLY AND OUTPUT
IMPEDANCE
The specific mains input voltage rating that your
amp has been manufactured for is indicated on
the rear panel of the amp. Your amp is provided
with a detachable mains (power) lead, which
should be connected to the mains input socket
on the rear panel of the amp.
The correct value and type of mains fuse is
specified on the rear panel of the amp. Never
attempt to bypass the fuse or fit one of the
incorrect value or type.
The output impedance select switch should
be set to the total impedance of the speaker
cabinet(s) (or load) being used.
If you have any doubt regarding your mains
electricity supply or the impedance of speaker
cabinet(s), please seek help from a qualified
engineer – your Marshall dealer can help you
with this.
Warning: your amp must be switched off and
disconnected from the mains electricity supply
before you:
• check and/or change any fuse; and/or
• change the output impedance selector for a
different setting.
Failure to comply with any of the points above
may damage your amp.

IMPORTANT SET UP INFORMATION

1. Set the impedance select switch to the
impedance of the combined load of the
2
speaker cabinet(s) you will be using.
2. Connect one or two speaker cabinets to the
speaker outputs.
Warning: failure to do the above may damage
your amp. When connecting a speaker cabinet
make sure that you use a proper speaker cable.
Never use a screened (shielded) guitar cable for
this purpose.
3. Ensure that both the power switch and
standby switch are set to the off position.
4. Connect the supplied mains (power) lead
into the power inlet on the rear panel first
and then into an electricity outlet.
5. Ensure that any master, volume and/or
output level controls on the front panel are
set to zero.
6. Plug your guitar into the input on the front
panel.
7. Turn the power switch on and wait a couple
of minutes.
8. Turn the standby switch on.
9. Turn the volume up to your preferred level
and you're ready to play.
TRANSPORTING YOUR EQUIPMENT
Please ensure that your amp is switched off,
unplugged from the mains electricity supply and
all removable cables have been disconnected
from your equipment before attempting to
move it.
Only move the amp on its own. Do not attempt
to move it while it is stacked on top of a cabinet
or other equipment.
