THE DSL100HR HAS TWO GAIN CHANNELS TO PRODUCE THAT LEGENDARY
MARSHALL SOUND WITH RICH FUNCTIONALITY FOR THOSE WHO REQUIRE
FLEXIBILITY AND UNQUESTIONABLE QUALITY. THE AMP CAN MOVE
BETWEEN TWO SOUNDS WITHIN EACH GAIN CHANNEL, SO THAT PLAYERS
CAN CREATE AND RELEASE THEIR PERSONALITY THROUGH SOUND.

WARNING! SAFETY INSTRUCTIONS
PLEASE READ THE FOLLOWING NOTICE IN FULL BEFORE ATTEMPTING TO REPAIR, SERVICE OR DISMANTLE ANY ITEM OF MARSHALL AMPLIFICATION PLC.
PLEASE NOTE THAT FAILURE TO OBSERVE
THE CONDITIONS SET OUT IN THIS NOTICE
MAY RESULT IN DEATH OR SERIOUS INJURY
TO YOURSELF AND/OR OTHERS. IT MAY
ALSO INVALIDATE THE MANUFACTURER’S
WARRANTY IN RESPECT OF THE ITEM OF
EQUIPMENT CONCERNED.
1. The information contained in this
Service Manual (and in all annexes,
diagrams and documents attached
to or accompanying this Service
Manual) is intended to be used by
authorised Marshall Amplification Plc
service centres or by approved waste
electrical and electronic equipment
reprocessing and recycling centres
only.
2. All repairs and servicing of Marshall
Amplification Plc equipment
(‘Marshall Equipment’) should only
be carried out by suitably trained and
qualified personnel at an authorised
Marshall Amplification Plc service
centre. For details of your nearest
authorised service centres please
contact the ‘Service Department’ at
Marshall Amplification Plc.
3. All reprocessing and recycling of
Marshall Equipment at the end of
its useful life should only be carried
out by suitably trained and qualified
personnel at properly approved waste
electrical and electronic equipment
reprocessing and recycling centres.
4. Marshall Equipment should always
be fully disconnected from the mains
electricity supply before attempting
to carry out any repair, servicing or
disassembly.
5. Even when Marshall Equipment has
been disconnected from the mains
electricity supply it may still retain
high voltage electrical charges that
are potentially hazardous to life and
health. Marshall Equipment may
also contain parts that remain at a
high temperature for a considerable
period of time after use. Extreme
caution should always therefore be
exercised when carrying out any
repairs, servicing or disassembly of
any Marshall Equipment.
6. All Marshall Equipment (including
its component parts) conform and
comply with relevant laws applicable
at the time of manufacture (including
but not limited to laws relating to
electrical safety, electromagnetic
compatibility and the presence of
hazardous substances.) Furthermore
all components are specific for their
intended use and have undergone
appropriate conformity approval.
In the event that during the
repair or servicing of any Marshall
Equipment it is necessary to replace
any component, part or material,
it is therefore essential that only
components, parts or materials that
have been approved by Marshall
Amplification Plc should be used.
7. Any safety warnings attached to
an item of Marshall Equipment
will comply with laws and industry
standards applicable at the time
such item of Marshall Equipment
was manufactured but may not
necessarily reflect current law
or standards. No safety warning
attached to any item of Marshall
Equipment should be removed during
servicing or repair.
MAINS INPUT & FUSE
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.
Save as set out below, Marshall
Amplification Plc accepts no responsibility
for any death, injury, loss or damage arising
from any non-observance of the above
conditions.
Nothing in these conditions shall limit
Marshall Amplification Plc’s liability for
death or injury to the extent that it
results from their direct negligence or its
employees.

STB (standby): This is used in conjunction
with the mains power switch (front panel

switch mains power on first, leaving
the output switch in the STB (standby)
position. Standby mode should also be
used to mute the amp during breaks
in performances to avoid stress to the
valves of the amplifier.

32. EMULATED OUT
Emulated line level output for
headphones or connection to a mixer.
The DSL is equipped with a high quality
emulated output using Softube-designed
studio cabinet emulation. This ensures
that your headphone and output signal
from this socket provide the best possible
tone for practice or recording.
Note: Using the emulated out does not
omit the need for a speaker load to be
connected to the amplifier (rear panel
function #33).
Note: For silent recording via emulated
out set the output switch to STB (front
panel function #24).

33. LOUDSPEAKERS
There are five speaker outputs available.
They are labelled according to the
intended impedances:
• 1 x 16 Ohm: connect a single 16
Ohm speaker cabinet to this jack.
• 1x 8 Ohm or 2 x 16 Ohm: connect
a single 8 Ohm speaker cabinet or
two 16 Ohm speaker cabinets.
• 1 x 4 Ohm or 2 x 8 Ohm: connect
a single 4 Ohm speaker cabinet or
two 8 Ohm speaker cabinets.
Warning: Although the amplifier has
five speaker outputs, never attempt to
connect more speaker cabinets than
rated. The safe combinations are: 1 x
16 Ohm, 1 x 8 Ohm, 2 x 16 Ohm, 1 x
4 Ohm or 2 x 8 Ohm only. Any other
speaker cabinet configuration may
stress the power amplifier section and
in extreme cases may lead to valve and/
or output transformer failure. NEVER
use DSL100HR or DSL40CR without a
speaker load.
