ENGLISH

1. Footswitch
Connecting the supplied footswitch here enables
you to perform two functions; you can change the
Dynamic Range and toggle the Reverb on and off.
The Dynamic Range switch functions exactly the
same as the front panel counterpart (11).

Effects Loop Send & Return Jacks
To increase the flexibility of your amplifier even
further, you may choose to add external effects in its
Series Effects Loop, which allows direct connection
of either floor pedals or rack processors, with the
Level switch (4) providing the correct operating
level. 

2. Send
Connect the (mono) input of an external effects
processor here.

3. Return
Connect the (mono) output of an external effects
processor here.

Tonal tip: Effects involving distortion or Wah Wah
aren’t usually put in an effects loop because they
sound best when they're ‘before’ the amp (i.e.
placed between the guitar and the amp’s input).
However, when it comes to your sound, it’s up to
you!

4. Ext FX (-10dBV / +4dBu)
This switch offers two different loop levels to enable
you to match the type of effect(s) connected to the
Series Effects Loop. The higher level (+4dBu: switch
‘in’) suits rack processors and the lower level
(-10dBV: switch ‘out’) suits floor pedals (stomp
boxes). 

Note: A similar level matching switch may also be
found on rack effect units, in which case the amp
and effects unit should be set to the same level.

5. Ext FX (Bypass/Loop)
When ‘out’ this switch completely bypasses the
circuitry involved in the effects loop. Push this switch
in to enable the loop.

Note: If this switch is accidentally pushed in and
there is nothing plugged in to the loop, the signal
will still pass through from send to return by means
of an internal link on the switching jacks. This link is
disconnected when something is plugged into the
return socket. The send socket has no effect on the
status of the internal link and could therefore be
used as a line out to a tuner for example if no
external FX are connected.

6. Speaker Outputs
WARNING! Never use the amplifier without a load
(speaker cabinet/s) attached!

There are two parallel loudspeaker output jacks
provided for connection to speaker cabinet(s).
ALWAYS ensure you use good quality speaker
(unshielded) cables. NEVER use guitar (shielded)
cables.

Always use a non-screened Marshall approved
speaker lead when connecting an extension cabinet
to these units.

7. Output Selector
This switch should be set to match your speaker
cabinet’s impedance. If more than one speaker
cabinet is connected then you should set the switch
to match the total impedance of the combination.
Check with your dealer if you are unsure.

16 & 8 ohms are provided for on the heads (2466
and 2266).

8 & 4 ohms are provided for on the combo (2266C).

Note: The impedance of the combo’s (2266C) own
speakers is 8 ohms. Make sure the combo’s output
selector is set to 8 ohms when no extension cabs
are connected.

8. HT Fuse
The correct value of this H.T. fuse is specified on
the rear panel of the amplifier. NEVER attempt to
bypass the fuse or fit one of the incorrect value!

9. Mains Input Socket with incorporated
Mains Fuse
Your amp is provided with a detachable mains
(power) lead, which is connected here. The specific
mains input voltage rating that your amplifier has
been built for is indicated on the back panel. Before
connecting for the first time, please ensure that your
amplifier is compatible with your electricity supply. If
you have any doubt, please get advice from a
qualified technician. Your Marshall dealer will help
you in this respect.

The correct value of mains fuse located in the small
drawer at the bottom of the mains socket is
specified on the rear panel of the amplifier. The
drawer contains a space for a spare fuse. NEVER
attempt to bypass the fuse or fit one of the incorrect
value!

Note: It is wise to carry spare HT and Mains fuses!
