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.
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.
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.
1.0 WARNING! SAFETY INSTRUCTIONS
PLEASE READ THIS MANUAL CAREFULLY BEFORE PLUGGING IN. FOLLOW ALL INSTRUCTIONS AND HEED ALL WARNINGS.
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.
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.

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

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.
