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.
