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!
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
7. Output Selector
6 | 7 | 8 |
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!
ENGLISH
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
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.
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).
