Marshall Amplification 2525H - REAR PANEL FUNCTIONS; Rear Panel Connectivity (Speakers, DI, Footswitch, FX Loop)

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.
