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 specific information.
Warning: failure to do the above may damage your amplifier. When connecting a speaker cabinet make sure that you use a proper speaker cable. Never use a screened (shielded) guitar cable for this purpose.

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 first and then into an electricity outlet.
4.
Ensure that the volume controls on the front panel are set to zero.
Warning: Before going any further, make sure that your amplifier is compatible with your mains electricity supply. If you have any doubt, please seek help from a qualified technician – your Marshall dealer can help you with this.
MAINS INPUT & FUSE:
The specific mains input voltage rating that your amplifier has been
manufactured for is indicated on the rear panel. Your amplifier 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 specified on the rear panel.
Never attempt to bypass the fuse or fit one of the incorrect value or type.
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.

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 val
ve 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 amplifiers 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 amplifier is
unmistakeably Marshall using 3x ECC83 preamp valves and 2x EL34 power valves to generate rich harmonics and exceptional tone. While the amplifier 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 fine tuning of your tone in the power stage for even greater tonal detailing.

OVERVIEW AND SPECIFICATION
1. POWER SWITCH
Turns your amplifier 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 amplifier 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. 5W).Note: reducing the power output allows
you to drive the power stage harder at
low volumes. This provides the ability to
benefit 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
amplifier increasing the higher
frequencies of your sound.
5. MASTER VOLUME
Adjusts output volume. At higher settings,
the power amplifier can be overdriven,
giving a classic overdrive sound.
EQ Settings: your Origin amplifier has
4 equalisation controls (presence, treble,
middle and bass) plus an amplifier 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.
