emulation. This ensures that your
headphone and output signal from this
socket provide the best possible tone for
practice or recording.
Note: For silent recording via EMULATED
OUT set the OUTPUT switch to STB (Front
Panel Function #14).
Important: Using EMULATED OUT does
not omit the need for a speaker load to be
connected (See Rear Panel Function #22).
22. LOUDSPEAKERS
There are three speaker cabinet output
jack sockets available. They are labelled
according to the intended impedances:
• 1 x 16 OHM: Connect a single 16
Ohm speaker cabinet to this jack.
• 1 x 8 OHM or 2 x 16 OHM: Connect
a single 8 Ohm speaker cabinet or
two 16 Ohm speaker cabinets.
WARNING - Although the amplier has
three speaker outputs, never attempt
to connect more speaker cabinets than
rated. The safe combinations are: 1 x 8
Ohm speaker cabinet, 2 x16 Ohm speaker
cabinets or 1 x 16 Ohm speaker cabinet.
Any other speaker cabinet conguration
may stress the power amplier section and
in extreme cases may lead to valve and/
or output transformer failure. NEVER use
DSL20HR or DSL20CR without a speaker
load.
16. MAINS INPUT
Connects the amplier to the mains
electricity supply.
Note: The MAINS INPUT socket has an
integrated fuse compartment. Ensure that
the value of a replacement fuse matches the
labelling on the amplier rear panel. You
MUST ALWAYS switch the amplier OFF
and disconnect it from the mains electricity
supply before attempting to access the fuse
compartment. If in doubt, contact your
Marshall dealer.
