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

rear panel of the amp. The correct value
and type of mains fuse is specied on the
rear panel of the amp.

of the incorrect value or type.
IMPORTANT SET UP INFORMATION
1. When using your amp with one or
more speaker cabinets, make sure
that they are connected to the correct

damage your amp. 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 and the output switch
is set to standby.
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 any master, volume and/
or output level controls on the front
panel are set to zero.
5. Plug your guitar into the input jack
socket on the front panel.
6. Turn the front panel power switch on
and wait a couple of minutes.
7. Select between 20W / 5W using the
output switch.
8. Turn the volume up to your preferred
level and you’re ready to play.

OVERVIEW AND SPECIFICATION

1. POWER
This is the on/off switch for the mains
power to the amp. When power is
switched on, the switch will light red.
Warning: please ensure that the amp
is switched off and unplugged from the
mains electricity supply before being
moved.
2. OUTPUT
The output power is in low power mode
(5W) when set to low, when in the middle
position it is set to standby and when set
to high power the unit runs at full power
(20W).
Standby mode: should be used during
breaks in performances, instead of leaving
the amp on full power. Always turn the
power on for two minutes before using the
standby switch.
3. PRESENCE

amp. Increasing the high frequencies adds
more bite to your sound.
4. BASS

It will add bottom end and depth to your
sound.
5. MIDDLE

7. OUTPUT MASTER / LEAD CHANNEL
The output master control adjusts the
output of the preamp section to the power
stage.
The lead channel is selected using the
footswitch (supplied PEDL-90003). The
channel can also be switched by using the
push/pull function of the output master
control. The amount of gain applied to the
lead channel can be controlled using the
input gain control (front panel function
10).
8. LEAD CHANNEL LED
The LED indicator will light and glow red
when the lead channel is selected.
9. LEAD MASTER
When the lead channel is active (front
panel function 7) the lead master control
adjusts the output level of the lead
channel.
10. INPUT GAIN
Adjusts the overall sensitivity of the input
circuit. It controls the gain level of the
clean/crunch rhythm clip mode and the
lead channel. The pull switch activates
rhythm clip mode, providing heavier, more
driven tones.
Note: the apparent drop in volume when
rhythm clip mode is selected may be
overcome by increasing the level of the
output master (front panel function 7).
11. INPUT
Use this jack socket to connect your guitar
to the amp.

FRONT PANEL FUNCTIONS CONTINUED

1. LOUDSPEAKERS
There are ve speaker outputs available.
These are 1/4” jack sockets. They are
labelled according to the intended
impedances:
• 16Ω: connect a 16 Ohm guitar cabinet
to this jack.
• 8Ω: connect a single 8 Ohm guitar
cabinet or two 16 Ohm cabinets.
• 4Ω: connect a single 4 Ohm guitar
cabinet or two 8 Ohm guitar cabinets.
Warning: although the amplier has
ve speaker outputs, never attempt to
connect more speakers than rated. The
safe combinations are: 1 x 16 Ohm, 1 x 8
Ohm, 1 x 4 Ohm, 2 x16 Ohm or 2 x 8 Ohm.
Any other speaker conguration may
stress the power amplier section and in
extreme cases may lead to valve and/or
output transformer failure.
Never use the 2525 without a speaker
load.
2. DI OUTPUT
A DI output allows you to connect to
recording device or sound desk.
Note: using the DI does not omit the need
for a speaker to be connected. See the
warning on rear panel function 1.
3. FOOTSWITCH
Connect the channel footswitch here
(PEDL-90003, supplied).
4. FX LOOP
The series FX loop connects the amp to
external FX (nominal level -10dBV). The
send jack socket connects to the input
of the external FX unit and the return
jack socket connects to the output of the
external FX unit.
Note: the send jack socket can be used
to connect to an external power amp. This
does not omit the need for a speaker to be
connected to the amplier’s output stage.
See the warning on rear panel function 1.
The return can be used to connect an
external preamp.

5. HT FUSE
The panel mounted fuse holder allows
access to replace blown fuses. If necessary
the HT fuse will blow to protect the
internal circuitry. This can sometimes
happen in the event of output valve
failure.
Note: replace the fuse only with the
value shown on the rear panel. Before
attempting to change the fuse you must
always rst switch the amp off and
disconnect it from the mains electricity
supply. If in doubt, contact your Marshall
dealer.
6. MAINS INPUT
Connects the amp to the mains power
supply.
Note: the mains input socket has an
integrated fuse compartment. Ensure
that the value of a replacement fuse
matches the labelling on the amp rear
panel. You must always rst switch off
and disconnect from the mains electricity
supply before attempting to access the
fuse compartment. If in doubt, contact
your Marshall dealer.
