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.

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.
