you with this.

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.

IMPORTANT SET UP INFORMATION

1. When using your amp with one or

more speaker cabinets, make sure

that they are connected to the correct

loudspeaker jack sockets.

Warning: failure to do the above may

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.

TRANSPORTING YOUR EQUIPMENT

Please ensure that your amp is switched

off, unplugged from the mains electricity

supply and all removable cables have been

disconnected from your equipment before

attempting to move it.

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

Adjusts the high frequencies of the power

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.
