DSL20HR

OWNER’S MANUAL

Congratulations on your purchase of this Dual Super Lead (DSL) amplier from

Marshall Amplication.

The DSL provides the legendary Marshall tone, allowing you to express your distinct

playing style and attitude.

From clean to distorted overdrives, the DSL 20 is a versatile all valve amp that allows

you to easily dial in the sound you desire.

This DSL amplier not only delivers the tone you expect from a Super Lead amplier

it is also packed with an array of features such as an effects loop, power reduction

and studio quality digital reverb. Right out of the box your DSL provides you with

the functionality you need to take your sound from rehearsal to the studio with

condence.

Your DSL amplier has been designed specically for those who need the full rich

tone of a valve amp in a compact and portable format. This makes the amp ideal for

a live environment, studio or at home thanks to the power reduction system.

We hope you enjoy performing, practicing and recording with your DSL amplier.

- The Marshall Team

The DSL 20 Head and DSL 20 Combo feature the same functions. The combo is

equipped with a 12” Celestion Seventy-80 speaker chosen for its ability to deliver

exceptional tone and exibility.

The DSL features two foot switchable channels: CLASSIC GAIN and ULTRA GAIN.

The CLASSIC GAIN channel can deliver sparkling clean sounds through to the more

aggressive break-up of a Marshall JCM800 amplier. The ULTRA GAIN channel

provides even more distortion and break-up for players looking for high gain tone

from their amplier.

Both channels share a passive three-band EQ, with BASS, MIDDLE and TREBLE

controls. The EQ section also features Tone Shift, which when activated recongures

the pre-amp mid frequencies making DSL ideal for contemporary metal tones,

especially when combined with higher gain settings.

The DSL 20 features professional quality digital REVERB and a series FX LOOP. The

LOW POWER function adds a further dimension to the DSL sound, giving you rich

valve tone at an ear-friendly volume.

use a proper speaker cable. Never use a

screened (shielded) guitar cable for this

purpose.

2. Ensure that the POWER switch is

set to the OFF position (Front Panel

Function #15).

3. Ensure the OUTPUT switch is in the

STANDBY position

(Front Panel Function #14).

FRONT PANEL FUNCTIONS

6. VOLUME

Controls the volume level of the ULTRA

GAIN channel.

EQUALISATION SECTION

7. TONE SHIFT

Recongures the preamp EQ network’s

mid frequencies adding a new dimension

to tonal shaping.

8. TREBLE

Controls higher frequencies of your

sound. Turning clockwise will increase

the highs making your sound brighter

and more crisp.

9. MIDDLE

Controls the middle register of your

sound. Turning clockwise adds girth.

Turning anticlockwise reduces the

middle frequencies ‘scooping’ the

sound – this is accentuated when used in

conjunction with Tone Shift (Front Panel

Function #7).

10. BASS

Controls the amount of lower frequency,

or bottom-end, in your sound. Turning

clockwise will increase the bottom-end

making the sound fuller.

Tonal Note: The preamp EQ network is

dynamic and highly interactive. Please note

that because of this, altering the setting of

one control can change the way that the

other controls behave – experiment to nd

your sound.

GAIN channel. As the amount of gain

increases, so will the distortion level in

your sound.

FRONT PANEL FUNCTIONS NOTES

11. PRESENCE

Controls the amount of higher frequency

content in your sound. Turn clockwise

to add bite for a more cutting tone.

PRESENCE is an power-stage function

and acts independently of the preamp

EQ network.

12. RESONANCE

Controls the amount of lower frequency

content in your sound. Turning this

control clockwise adds a resonant

bass boost, increasing bottom end.

RESONANCE is a power-stage function

and acts independently of the preamp

EQ network.

13. REVERB

Controls the overall REVERB level.

14. OUTPUT

This three position rocker switch

combines STB (standby) and HIGH/

LOW output power functions. The

output stage and power control for this

amplier has been designed to deliver

the optimum tonal performance at

all power levels. The HIGH and LOW

output functions allow the user to

choose between two congurations of

the internal power supply. These two

congurations give the choice between

two output power levels, but ensure that

the output valves behave in the same

way for both. This means the amplier

can be put into LOW power mode

without compromising on tone.

HIGH: This is the 20 Watt high power

setting.

STB (standby): This is used in conjunction

with the mains POWER switch (Front Panel

Function #15). When powering up, always

switch mains POWER on rst, 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 amplier.

LOW: This is the 10 Watt low power setting.

15. POWER

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 amplier 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 conguration

may stress the power amplier 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 amplier 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 amplier rear panel. You

MUST ALWAYS switch the amplier OFF

and disconnect it from the mains electricity

supply before attempting to access the fuse

compartment. If in doubt, contact your

Marshall dealer.

17. FX LOOP RETURN

Connect the output of an external FX

pedal or processor.

18. FX LOOP SEND

Connect the input of an external FX

pedal or processor.

19. F/S

Connect the supplied 2-way CHANNEL

and FX LOOP footswitch here (PEDL-

90012).

20. AUDIO IN

Connect an external device here for

practice or to jam along with music.

21. EMULATED OUT

Frequency compensated line level

output for headphones or for connection

to a mixer. The DSL is equipped with

a high quality emulated output using

Softube-designed studio cabinet
