From Jim Marshall
I would like to personally thank you for
selecting one of our JCM 2000 Dual Super
Lead valve amplifiers.
Since I started Marshall Amplification in
1962 I have witnessed some incredible
breakthroughs and advances in amplifier
design technology, such as master volume
amps, switchable channels, reverb, MIDI
technology, speaker emulation and digital
effects processing, to name just a few. These
may seem like every day features nowadays
but this certainly wasn’t always the case.
However, the same values that were present
in the first Marshalls are still here today. That
is, solid workmanship, reliability, stylish looks
and above all great Marshall tone.
The DSL201 and DSL401 are our latest all
valve amplifiers and as such are really direct
descendants of our classic all valve amps.
Combining all of the aforementioned values
plus a few extra attributes such as versatility,
switchable channels, reverb, a big sound and
of course, I am proud to say, all of the
magical Marshall tone that you could want.
The JCM 2000 range is truly a testament to
the Marshall legacy of great guitar products.
I would like to wish you every success with
all of your musical endeavours and also your
new Marshall JCM 2000 Dual Super Lead
valve amplifier, which I am sure you will find
a pleasure to play for many years to come.
Yours Sincerely,

Introduction
With the introduction of the Marshall JCM2000 range of DSL50 and 100 heads, the
TSL100 head and the TSL122 combo, the quintessential definition of ultimate tone
and usable features has been rewritten. This quartet of great amps has now spawned
a new generation of compact, lower power combo amps, the DSL201 and DSL401,
destined to be classics for both studio and session/club gigs.
As the names imply these amps are 20 Watts and 40 Watts respectively, but as these
are true valve amps, built to exacting standards, do not let the lower power ratings
lull you into thinking that they are mere practice amps, as nothing could be further
from the truth! The benefits of using a lower powered amp are many fold, not least
that of being able to push the output valves harder for extra warmth at manageable
volume levels. Just remember how many famous artists have used smaller amps to
record those classic tracks and how many use lower powered amps on stage, to help
balance the sound. Worried that your amp is great for the studio and small club, but
not for bigger gigs? Well don’t, there are ways of making them sound much bigger
than they really are. Just adding a Marshall 1960 4x12” is going to increase the
spread and SPL of your sound, by simple physics. If not mic or D.I. through the PA.
The onboard D.I. output of your DSL201 or 401 contains Marshalls acclaimed speaker
emulation circuit, making accurate sounding D.I.ing as simple as plugging in a cable!
Silent recording in your project studio? Again, use the speaker emulated D.I. output,
only this time turn down the ‘output master’ volume control (which by the way,
controls the apparent output power) to zero and still capture the full valve tone of
your amp on tape (or disc!)
WARNING! - Important safety instructions
A. ALWAYS fit a good quality mains plug conforming to the latest B.S.I. standards where necessary (UK only).
B. NEVER attempt to by-pass the fuses or fit ones of the incorrect value.
C. NEVER attempt to replace fuses or valves with the amplifier connected to the mains.
D. DO NOT attempt to remove the amplifier chassis, there are no user serviceable parts.
E. Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been
damaged in any way, such as the power supply cord or plug is damaged, liquid has been spilled or objects
have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally
or has been dropped.
F. NEVER use an amplifier in damp or wet conditions.
G. ALWAYS unplug this apparatus during lightning storms or when unused for long periods of time.
H. Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles and at
the point where they exit from the apparatus.
I. DO NOT switch the amplifier on without the loudspeaker connected.
J. ENSURE that any extension cabinets used are of the correct impedance.
K. PLEASE read this instruction manual carefully before switching on.
Follow all instructions and heed all warnings.
WARNING : This apparatus must be earthed!
WARNING : Do not obstruct ventilation grille and always ensure free movement of air around the amplifier!
USA ONLY - DO NOT defeat the purpose of the polarised or grounding type plug. A polarised plug has two
blades with one wider than the other. A grounding type plug has two blades and a third grounding prong.
The wide blade or the third prong are provided for your safety. When the provided plug does not fit into your
outlet, consult an electrician for replacement of the obsolete outlet.

Please note both models DSL201 and DSL401
are described together, any model variations are
indicated.
✪ User Hint - where you see text starting with
this sign, we have described some slight
technical paraphenalia in order for you to
understand what is going on inside your amp and
we hope will help you in creating the tone that is
best for you and your amp.
1. Input Jack
As most manuals state, plug your guitar in here.
✪ User Hint - Amusement aside, it is
worthwhile remembering that you should use a
high quality guitar lead to achieve optimum
performance. If you are unsure what constitutes
a high quality lead then most good music stores
should be able to give you good advice, but
remember, it may not be the cheapest one going!
It is also worth pointing out here that how an
amp sounds is VERY dependent on the type of
guitar you use. For instance, a guitar with
humbucker type pick-ups is not going to sound
as open and clean as one with single coil type
pick-ups, yet will provide that great mid range
bark that we are accustomed to for rock playing.
2. Clean Gain
This controls the preamp level of the clean
channel, at lower settings the sound will be very
clean and at higher settings the sound will start
to ‘Crunch’ up in a traditional blues sort of way.
In between, around midway, depending on what
type of guitar you are using, you will find some
great semi-clean/semi-crunch tones, just like
those great vintage amps that had minimal
features, but great tone.
✪ User Hint - there is a capacitor across the
gain control that brightens up the tone when set
to lower levels. This helps to ‘cut’ through at
low volumes and adds ‘twang’ to the tone. As
you bring up the gain control the effect of this
decreases and the tone becomes fatter. If you
Continuing with the features of your amp, both the DSL201 and 401 have two
totally independent, footswitchable channels, notably ‘Clean’ and ‘Overdrive’ which
cover the whole range of tones from sparkly clean, through classic and modern
‘Crunch’, through to super-saturated Lead Overdrive.
On top of this, the DSL401 offers a three channel option by having the ability to
(foot)switch between OD1 and OD2 - OD2 having even more gain than OD1 - in fact
a staggering 20dB more! Thus giving the ability to switch from great clean to
crunch and then to lead. Remember, the Clean channel not only does clean, it
crunches up in a great traditional way too, just turn it up and drop the apparent
output power (output master) down to a socially acceptable level.
Rounding out the features, your DSL201 or 401 also has a parallel FX loop with a
mix control and large spring ‘Sound Enhancements’ reverb, with footswitch facility
(DSL401 only).
It is important to mention here that your DSL201 or DSL401 use EL84 output
valves, as opposed to either the 5881/6L6 or EL34 valves used in bigger Marshall
amps. The EL84 is the classic output valve for smaller British style amps (and some
U.S. ones too) and is a great valve to achieve superb tone at lower power levels.
Normally they are used in a very simple circuit that features no negative feedback
and are run in the cathode biased mode which gets close to them being run in class
A, which makes for a very squashy compressed tone, as typified in the VOX AC30
for instance. Whilst this mode is great for these classic amps, we felt that this
simple operating mode limited the amount of versatility required from an amp as
diverse as the DSL201 & 401, in this modern age. Therefore, after careful study of
how these classic amps worked and how the bigger Marshall’s worked, a fresh
design that covers a broader spectrum of tones has been incorporated into the
DSL201 and 401. We feel that it does it with great style.
DSL201 & DSL401 Front Panel Features (pages 32 & 34)

find the tone too thin with the gain control down
either take some of the high end off with the
treble control, or alternatively, bring the clean
gain control up until you achieve the depth of
tone you want and then control the volume of
the amp with the ‘master volume’ control.
3. Clean Treble, Mid, Bass
These controls vary the E.Q. and voicing of the
Clean channel.
✪ User Hint - These controls are early on in the
amplifier chain and as such not only control the
tone of the Clean channel, but also how the clean
channel reacts ‘gain’ wise. For instance, if the
mid control is advanced (especially with higher
gain control settings) the sound will become
more ‘singing’ in a blues/traditional rock kind of
way. But if the mid control is backed off
towards (or even) zero the gain emphasis is
placed on the treble and bass controls and gives
more to work on, especially on cleaner, lower
gain settings, as would be the case for country,
jazz, or good old chord strumming.
A good starting point is to set these three
controls to their ‘midway’ position and by
experimenting with the ‘feel’ of how they
interact with the amp, build up a wide palette of
tones for future use.
4. Channel Switching
The channels of your DSL201 or DSL401 can
either be switched from the front panel, or via an
external footswitch - connection of the
footswitch is described later.
DSL201 - The front panel switching
arrangement consists of two LEDs and a single
pushswitch, to switch between either the clean
(Green LED) or Overdrive channels (Red LED).
Switch out is Clean, switch in is Overdrive.
DSL401 - Here the front panel switching
arrangement consists of three LEDs (Green =
Clean, Yellow = OD1, Red = OD2) and two
pushswitches, marked CLN/OD and OD1/OD2.
To select Clean the switch marked CLN/OD
must be released to its out position (Green LED
will be on). To select either OD1 or OD2, push
the CLN/OD switch in and select either OD1 or
OD2 by pushing or releasing the switch marked
OD1/OD2 and the appropriate Yellow or Red
LED will illuminate. To revert back to Clean,
release the CLN/OD switch once more. Do not
worry, you do not have to go through OD1 to
reach OD2, these channels can be pre-selected.
✪ User Hint - These functions are repeated on
the footswitch. Remember that plugging the
footswitch into the amp will override the front
panel pushswitches.
5. Overdrive Gain
This controls the amount of gain drive available
for the overdrive channel, from mildly almost
clean crunch to super-saturated overdrive,
depending where this control is set, i.e. lower is
less and higher is more. Wherever this control is
set is going to give you a wide palette of tones to
work with, depending on the type of guitar, EQ
settings, how hard you push the power amp, etc.
Note: the difference between OD1 and OD2
(DSL401 only) is approx 20dB more gain on
OD2. The DSL201 is preset to the gain levels of
OD2 and does not have the OD1 facility.
✪ User Hint - Due to the immense amount of
gain and saturation available on the preamp of
the DSL401, particularly when using high output
humbucker pick-ups, the 20dB difference
between OD1 and OD2 may become less
apparent. In this case, back off the settings of
the gain control slightly until the difference
becomes more useable again.
✪ User Hint - One of the beauties of using a
lower power amp is that it makes the power amp
distortion more easy to use and by lowering the
input gain control and bringing up the channel
volume control will give you a whole new load
of tones to play with, as well as making the amp
run quieter, especially if you use the ability of
the ‘master volume’ to emulate a lower powered
amp.
6. Overdrive Volume
This control adjusts the level of sound coming
out of the overdrive preamp channel and allows
you to balance it against the Clean channel.
✪ User Hint - To achieve the normal Marshall
style heavy rock ‘punch & crunch’ especially at
lower volume levels, this control should be used
to keep the volume down and the output Master
Volume should be kept higher. To achieve a
squashier type tone, great for lead work, then use
this control higher and bring the level down on
the output Master Volume.
✪ User Hint - When using the less gain/more
level way of driving the power stage, keep the
overdrive gain low and use this volume control
to drive the power amp.
7. Overdrive Treble, Middle, Bass
As opposed to the ‘Clean’ channel, these
controls are placed after the distortion generating
circuitry of your amp and as such affect the
texture of the tone, rather than the gain of the
channel, especially when using high levels of
preamp gain.
✪ User Hint - Although many textures are
available from this relatively simple
configuration, a good starting point (again) is to
set everything midway. For a more modern

heavy’ tone, turn the mid control down and
boost the treble and bass. For a more classic
‘rock’ tone bring back the mids and bring the
treble and bass down a bit.
✪ User Hint - When using the less gain / more
volume approach, the tone controls can be used
to help ‘push’ the power amp for a more refined
tone.
8. Master FX Mix
This controls the balance of the return from the
parallel FX loop (see rear panel details for
connection) with the amps direct signal.
✪ User Hint - As the FX loop is of the parallel
kind, this is where you should use time delay
effects (i.e. echo, reverb, pitch shifting, chorus,
etc.). For optimum use the direct signal in your
processor should be turned to zero so that only
the effect signal is returned to the amp, this way
the tone integrity of the direct amp signal is
unimpaired.
9. Master Reverb
This controls the level of the internal spring
reverb circuitry from a slight shimmer to a
cavernous depth. DSL401 only - the reverb has
the facility of being footswitchable via the rear
panel socket and optional PEDL-10013
footswitch.
10. Master Volume
Apart from the obvious function of being the
master level control for the whole amp
(regulating the output volume of both the clean
and the overdrive channels), this control actually
affects the apparent power level of the power
amp section itself. This means that, at lower
settings, the amp acts and feels like an even
lower powered amp, along with the kind of
smooth saturation that you get from pushing a
power amp into distortion.
✪ User Hint - As the (rear panel mounted)
speaker emulated D.I. output is derived from this
circuit you can balance the sound coming out of
the loudspeaker from zero to full, whilst
maintaining a constant level out of the D.I.
output and enjoy the tonal qualities of a push-
pull valve output stage - ideal for silent
recording, direct to the desk.
11. Standby Switch
This turns the high voltage feed to operate the
valves on and off.
✪ User Hint - This switch should be used for
(a) allowing the amp to warm up before turning
the Standby on (at least a minute - preferably 2/3
minutes if possible) and (b) turn the Standby
switch off when taking a break (rather than
turning off the whole amp), thereby keeping
your amp at the ‘ready’, without waiting for it to
warm up again. Remember to do these two
simple rules and your valves will love you for it
and should last an awful lot longer before
replacement is needed.
12. Power Switch
This turns the mains electricity that feeds your
amp on and off. As stated before, turn this
switch on for at least a minute or two before
turning the Standby on, to allow your amp to
warm up.
✪ User Hint - For environmental reasons at
least, if leaving your amp for more than a normal
gig type break or so, turn your amp off at this
switch, it will save electricity. Also, if leaving
your amp unused for a long time, always
remember to disconnect your amp’s power cord
from the mains supply, at the very least it will
prevent someone else accidentily turning it on
without realising.
1. Channel Footswitch Jack
This socket takes the jack connected to the lead
of the channel change footswitch
(CLEAN/OVERDRIVE - DSL201, CLN/OD &
OD1/OD2 - DSL401).
2. Reverb Footswitch -(DSL401 only)
Takes the optional footswitch (PEDL-10013) to
remotely control the reverb function.
3. FX Loop Send Jack
Connects the DSL amp to the input of the
external FX processor.
4. FX Loop Return Jack
Connects the output of the external FX processor
back into the DSL amp circuit.
5. Speaker Emulated D.I. Out Jack
Line level, emulated output signal for
connection into PA or recording Mixing Desks
etc.
DSL201 & DSL401 Rear Panel Features (pages 32 & 34)

6. Loudspeaker Output Select -
(DSL401 Only)
This switch selects the output impedance of the
amplifier for either 8 or 16 ohm use, to match to
alternate speaker systems. Although more on
this will be covered later, it is important to
remember that the internal loudspeaker is 16
ohms and that the amp must be set to match that
(16 ohms).
7. Loudspeaker Output Jacks
One (1) only on DSL201, two (2) on DSL401.
These are identified by having RED jack socket
nuts and connect the amplifier output to either
the internal (or an external) loudspeaker system.
WARNING! At no time must the amplifier be
allowed to run with no loudspeaker (or
appropriate loudspeaker type load) connected to
its output. Otherwise serious and expensive
damage may occur.
8. H.T. Fuse - See specifications for
correct value
This fuse protects your amp in the case of a fault
occurring with any of the high voltage circuit of
your amp. The usual reason for this to blow is
when an output valve has become faulty.
9. Mains Input
Use the supplied power cord to connect your
amp to the mains supply.
10. Mains Fuse - See specifications
for correct value
This fuse provides overall safety protection in
the case of your amplifier developing a major
electrical fault.
✪ User Hint - The fuses fitted to your amp are
there to provide you with safety protection in the
case of a fault developing. If they blow it means
something is wrong, usually a valve is getting
old, but under no circumstances fit a fuse of a
different value to stop it from blowing, as this
could be very expensive in terms of safety and
cost. Remember, if a fuse blows, it has blown
for a reason.
LOUDSPEAKER SYSTEMS
The DSL201 and DSL401 combo amps are each
fitted with a Marshall designed 12” loudspeaker,
each one developed to work with your amp to
produce the great tone that you expect from a
Marshall amp. The 1x12” format makes for a
very highly portable package that works great in
most circumstances. However, if you require a
bigger sound, or just a different one, there are
numerous cabinets manufactured by Marshall
that will interface with your DSL combo, with
ultimate ease.
The DSL201 is fitted with a single loudspeaker
socket preset at an impedance of 16 ohms, which
is normally plugged into the internal 16 ohm 12”
loudspeaker. To use an external loudspeaker,
just unplug the internal speaker and plug into
your external cabinet (this must be 16 ohms
only), for instance, a Marshall 1960 4x12”.
The DSL401 is fitted with two parallel wired
loudspeaker jack sockets and a selector to switch
between the normal 16 ohms (to suit the internal
speaker) or 8 ohms. This makes the choice of
extension cabinets even wider. For instance, not
only could you use a Marshall 1960 4x12” cab,
with or without the internal speaker (set amp to
8 ohms if using both, keep on 16 ohms if using
without internal speaker), but you could also
make the choice of various Marshall 1x12” or
2x12” extension cabs. But always make sure
that the output selector is set correctly !
i.e.
1 x 16 ohm speaker = 16 ohm output
2 x 16 ohm speaker = 8 ohm output
1 x 8 ohm speaker = 8 ohm output
WARNING! Never operate your DSL valve
amp without a loudspeaker, or suitable
loudspeaker type load, connected to the output,
even when using the output Master Volume set
to zero for silent recording. Otherwise
expensive damage may occur!
USING EFFECTS SYSTEMS
Your DSL combo amp is fitted with parallel FX
Loop, this is placed after the gain and distortion
parts of the preamp and is the ideal place for
inserting time varying effects, such as delay,
digital reverb, chorus, pitch shifting, etc. By
being a parallel loop, this means that the direct
signal is kept within the DSL’s circuit and
therefore your tone is not degraded by sending it
outside the amp. To use the loop connect your
effects processor (rack type units are better at
this job) as described earlier, turn the effects
units direct signal path off (the FX units manual
will tell you how to do this), set up the unit to
give you the effect you require and then balance
your direct sound and effected sound using the
FX MIX control on the front of your amp. Easy!
Floor type effects stomp boxes are designed to
work in between a guitar and the input of an amp
and should not be used in a parallel loop,
otherwise some very weird and undesired effects
could occur. For their best use, use them where
they are designed to go.
