WARNING! SAFETY INSTRUCTIONS
PLEASE READ THE FOLLOWING NOTICE IN FULL BEFORE ATTEMPTING TO REPAIR, SERVICE OR DISMANTLE ANY ITEM OF MARSHALL AMPLIFICATION PLC.
MAINS INPUT & FUSE
The specic mains input voltage rating
that your amp has been manufactured for
is indicated on the rear panel of the amp.
Your amp is provided with a detachable
mains (power) lead, which should be
connected to the mains input socket on the
rear panel of the amp. The correct value
and type of mains fuse is specied on the
rear panel of the amp.
Never attempt to bypass the fuse or t one
of the incorrect value or type.
PLEASE NOTE THAT FAILURE TO OBSERVE
THE CONDITIONS SET OUT IN THIS NOTICE
MAY RESULT IN DEATH OR SERIOUS INJURY
TO YOURSELF AND/OR OTHERS. IT MAY
ALSO INVALIDATE THE MANUFACTURER’S
WARRANTY IN RESPECT OF THE ITEM OF
EQUIPMENT CONCERNED.
1. The information contained in this
Service Manual (and in all annexes,
diagrams and documents attached
to or accompanying this Service
Manual) is intended to be used by
authorised Marshall Amplication Plc
service centres or by approved waste
electrical and electronic equipment
reprocessing and recycling centres
only.
2. All repairs and servicing of Marshall
Amplication Plc equipment (‘Marshall
Equipment’) should only be carried
out by suitably trained and qualied
personnel at an authorisd Marshall
Amplication Plc service centre. For
details of your nearest authorised
service centres please contact the
‘Service Department’ at Marshall
Amplication Plc.
3. All reprocessing and recycling of
Marshall Equipment at the end of
its useful life should only be carried
out by suitably trained and qualied
personnel at properly approved waste
electrical and electronic equipment
reprocessing and recycling centres.
4. Marshall Equipment should always
be fully disconnected from the mains
electricity supply before attempting
to carry out any repair, servicing or
disassembly.
5. Even when Marshall Equipment has
been disconnected from the mains
electricity supply it may still retain
high voltage electrical charges that
are potentially hazardous to life and
health. Marshall Equipment may
also contain parts that remain at a
high temperature for a considerable
period of time after use. Extreme
caution should always therefore be
exercised when carrying out any
repairs, servicing or disassembly of
any Marshall Equipment.
6. All Marshall Equipment (including
its component parts) conform and
comply with relevant laws applicable
at the time of manufacture (including
but not limited to laws relating to
electrical safety, electromagnetic
compatibility and the presence of
hazardous substances.) Furthermore
all components are specic for their
intended use and have undergone
appropriate conformity approval.
In the event that during the repair
or servicing of any Marshall
Equipment it is necessary to replace
any component, part or material,
it is therefore essential that only
components, parts or materials that
have been approved by Marshall
Amplication Plc should be used.
7. Any safety warnings attached to
an item of Marshall Equipment
will comply with laws and industry
standards applicable at the time such
item of Marshall Equipment was
manufactured but may not necessarily
reect current law or standards. No
safety warning attached to any item
of Marshall Equipment should be
removed during servicing or repair.
Save as set out below, Marshall Amplication
Plc accepts no responsibility for any death,
injury, loss or damage arising from any non-
observance of the above conditions.
Nothing in these conditions shall limit
Marshall Amplication Plc’s liability
for death or injury to the extent that it
results from their direct negligence or its
employees.

FRONT PANEL FUNCTIONS
1. USB
Connect via USB to use CODE as a DAW
interface, to play tracks from your music
library, to get rmware updates and
control via MIDI.
To get CODE rmware updates:
hp://my.marshall.com/Downloads
Follow this link to quickly and easily keep
your CODE amplier’s rmware up to date.
2. INPUT
Use this jack socket to connect your
guitar to the amplier. Use a good quality
screened/shielded guitar cable to help
prevent noise interference.
3. GAIN
Controls the amount of gain introduced to
a preset. The higher the gain, the harder
the preamp is driven.
4. BASS
Turning the bass control will adjust the
warmth and low-end depth of your sound.
5. MIDDLE
Adjusting the middle control will vary the
amount of body in your sound by boosting
or cutting midrange frequencies.
6. TREBLE
Increasing the treble will make your sound
brighter and more cutting. Turning the
treble down will decrease tonal edge and
make the sound softer.
7. VOLUME
Controls the volume level within a selected
preset.
Because gain, bass, middle, treble &
volume are stored as part of a preset,
these panel tone controls only become
active when they are used.
8. MASTER
Controls the overall volume level of your
CODE amplier.
9. PRESET
A preset is a combination of preamp,
power amp & speaker models, with tonal
settings and FX: chorus, anger, tremolo,
delay etc, stored to a single location within
your CODE amplier’s memory.
10. EDIT
Use the EDIT selector to deep edit a
Preset. Push the EDIT selector to preview
the stored gain, bass, middle, treble &
volume settings.
11. F/C
Use this jack socket to connect the CODE
footcontroller.
12. AUX INPUT
Use this dedicated mini-jack socket to
connect an external music player to
practice with or jam along to music.
13. HEADPHONE OUTPUT
Use this mini-jack socket to connect
headphones for ‘silent’ practice. This can
also be used as a line out.
14. ON/OFF
This is the mains power on/off switch.

BOOK-80010-01 | M3390.054
FRONT PANEL FUNCTIONS (CONTINUED)
15. PRE FX
This is where you will nd FX that would
typically plug into a conventional amplier
between the guitar and the amplier’s
input. These FX would typically be in pedal
form, and also known as ‘stompboxes’.
16. AMP
AMP is short for preamp. MST modelling
faithfully recreates classic and modern
Marshall valve tones as well as other
famous valve amp tones. Each AMP model
creates an authentic preamp setting. The
MST preamp models are classied into
three groups: clean, crunch & overdrive.
17. MOD
MOD is short for Modulation. Modulation
FX in a conventional setup can be in
stompbox or rack form and often connect
via amplier’s FX loop.
18. DEL
DEL is short for delay. Delay FX in a
conventional setup can be in stompbox
or rack form and often connect via an
amplier’s FX loop. When you select DEL
the switch’s LED will remain lit red for two
seconds before ashing to indicate the
current delay tempo.
19. REV
REV is short for reverb. Reverb FX in a
conventional amplier setup can be in
stompbox form, rack form or integrated
within an amplier.
20. POWER
This is the section of a conventional
amplier that provides power to drive
the speaker(s). The power valves are an
integral part of how an all-valve amplier
sounds. MST modelling faithfully recreates
the four valve power amps models in
CODE.
21. CAB
CAB is short for speaker cabinet. A cab’s
speaker conguration and its size play
a signicant role in the overall sound
produced by the whole amplier setup.
The MST modelled speaker cabinets
in your CODE amplier are faithful
recreations of classic Marshall cabs.
22. EXIT/STORE
While on any screen pressing EXIT/STORE
returns you to the main preset screen.
Press and hold EXIT/STORE while on any
screen to QUICK STORE your edited
settings. Your edited settings will store
over the current preset and the display will
return you to the main preset screen.
23. DISPLAY
The display screen shows a preset’s name,
number, parameter settings and the tuner
display.
