DESIGNING AND BUILDING IT FOR YOU.

THE MARSHALL TEAM

IMPORTANT SET UP INFORMATION:

1. When using your Origin with an

extension speaker cabinet(s), make

sure that the speaker cabinet(s) is

connected to the correct loudspeaker

jack socket(s). See section 4.1, 4.2 and

4.3 for specic information.

Warning: failure to do the above

may damage your amplier. When

connecting a speaker cabinet make

sure that you 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 3.1).

3. Connect the supplied mains (power)

lead into the mains input on the rear

panel rst and then into an electricity

outlet.

Warning: Before going any further, make

sure that your amplier is compatible

with your mains electricity supply. If you

have any doubt, please seek help from a

qualied technician – your Marshall dealer

can help you with this.

MAINS INPUT & FUSE:

The specic mains input voltage

rating that your amplier has been

manufactured for is indicated on the rear

panel. Your amplier is provided with a

detachable mains (power) lead, which

should be connected to the mains input

socket on the rear panel. The correct

value and type of mains fuse is specied

on the rear panel.

Never attempt to bypass the fuse or t

one of the incorrect value or type.

4. Ensure that the volume controls on the

front panel are set to zero.

5. Plug your guitar into the input jack

socket on the front panel.

6. Select either high, mid or low power

(front panel function 3.2).

7. Turn the front panel switch on and wait

a couple of minutes.

8. Turn the volume up to your preferred

level and your amplier is ready to play.

TRANSPORTING YOUR EQUIPMENT:

Please ensure that your amplier is

switched off, unplugged from the mains

electricity supply and all removable

cables have been disconnected from your

equipment before attempting to move it.

WARNING! SAFETY INSTRUCTIONS

PLEASE READ THIS MANUAL CAREFULLY BEFORE PLUGGING IN. FOLLOW ALL INSTRUCTIONS AND HEED ALL WARNINGS.

The combo enclosures and speaker

choices have been carefully selected to

bring out the natural valve tone with the

20W combo being loaded with a Celestion

V Type 10” speaker and the 50W Combo

using a Celestion Midnight 60 12”

speaker.

Additional functionality such as the foot

switch gain boost, effects loop, and ability to

run the ampliers without a speaker load,

make the Origin range exceptional for the

modern player.

Available in both 20W and 50W power

outputs and as either a head or combo,

every Origin has been designed to offer

the perfect solution for players looking

to create great music.

The tone of the Origin amplier is

unmistakeably Marshall using 3x ECC83

preamp valves and 2x EL34 power

valves to generate rich harmonics and

exceptional tone. While the amplier is a

single channel unit, the design of the tone

circuit means it offers two very distinctive

voices. Accessing your preferred sound

can be easily achieved using the inbuilt tilt

control which when turned fully counter

clockwise will access a subtler tonal

structure. Dialling the tilt control fully

clockwise will increase the brightness of

sound for a more cutting tone. A presence

control also allows ne tuning of your tone

in the power stage for even greater tonal

detailing.

OVERVIEW AND SPECIFICATION

1. POWER SWITCH

Turns your amplier on and off.

2. OUTPUT LEVEL

Adjusts the output power level. At high

power the output will be the maximum

available power level. At mid power the

output of the amplier is set for quieter

performance use and recording (ORI20:

approx. 3W / ORI50: approx. 10W). At

low power the output will be reduced for

home practice (ORI20: approx. 0.5W /

ORI50: approx. 0.5).

Note: reducing the power output allows

you to drive the power stage harder at

low volumes. This provides the ability to

benet from the rich tonal qualities that a

valve power amp can create without the

need to operate at loud volume levels.

3. POWER LIGHT

When the unit is switched on this light

will illuminate.

4. PRESENCE

Adjusts the response of the power

amplier increasing the higher

frequencies of your sound.

5. MASTER VOLUME

Adjusts output volume. At higher settings,

the power amplier can be overdriven,

giving a classic overdrive sound.

EQ Settings: your Origin amplier has

4 equalisation controls (presence, treble,

middle and bass) plus an amplier channel

voice control (tilt). All these controls allow

you to adjust the frequency and voicing.

Each control is highly effective and

interactive.

6. TREBLE

Controls the higher frequency of

your sound.

7. MIDDLE

Controls the middle frequency of

your sound.

8. BASS

Controls the lower frequency of

your sound.

FRONT PANEL FUNCTIONS

9. TILT

Adjusts the voice of your Origin from

normal to high treble at the input stage.

Tilt: this control provides a blend between

normal and high treble pre-amplier

channels on a classic Marshall. Dialled all

the way to the left the sound is warm and

full, providing a thick overall tone. When

dialled all the way to the right the overall

tone is brighter for players looking for

more cut through and bite. When set at 12

o’clock the tilt control provides an equal

blend of both pre-amp voicings.

10. GAIN

Controls the amount of pre-amp gain

applied to your sound, the more gain

the more distortion. Pulling the control

knob activates a gain boost increasing the

level of drive in the pre-amp. This can be

operated using a 2-way foot switch

(PEDL-90016).

Note: when a foot switch is connected

it will override the front panel control

meaning the gain boost can only be turned

on and off using the foot switch.

11. INPUT

Connect your guitar to the amplier using

a ¼” instrument cable.
