Jack socket for the connection of the optional
footcontroller.
2. Loudspeaker Outputs
Connect the two loudspeaker cabinets provided
to the speaker outputs using the speaker leads
supplied.
If you would like to use your MG15HCFX amplifier
head with another speaker system (such as a full
size 4x12" cabinet), ensure that the amplifier is
provided with a total load equal to or greater than
8 ohms.
Always use a non-screened Marshall approved
speaker lead when connecting an extension
cabinet to these units.

connection of a pair of headphones. When a jack is
inserted into the headphone socket the unit’s
speaker is muted.
Power
The Power switch (17) turns the amplifier on and off. If
current settings have not been stored they will be lost.
Restoring Settings - WARNING ALL AMP &
FOOTCONTROLLER SETTINGS WILL BE LOST
To restore the unit to factory settings (see handbook
rear cover) you must hold the Store switch (12) while
powering on the unit. The Clean/Crunch (3) and OD
(5) lights will light orange. You can then release the
Store switch (12).
Resetting the amplifier will erase all user Channel
presets and all user Footcontroller settings, replacing
them with the factory presets.
Channel Selection
The amplifier has 4 channels - Clean, Crunch, OD-1 &
OD-2.
Pressing the Clean/Crunch switch (3) selects between
the Clean (Green Light) and Crunch (Red Light)
channels.
Pressing the OD-1/OD-2 switch (5) selects between the
OD-1 (Green Light) and OD-2 (Red Light) channels.
When moving from an OD channel to a
Clean/Crunch channel, the unit remembers the last
channel you were in before leaving. E.g. If you have
moved from the Crunch Channel to an OD channel
and you press the Clean/Crunch switch (3), the
amplifier will revert back to the Crunch channel -
rather than starting again in the Clean channel.
Modes
The amplifier operates in two modes - Preset and
Manual.
To change between these two modes, you must hold
the Tap switch (10) down for at least two seconds.
When in manual mode the Store switch (12) lights red
and the selected channel light (3 or 5) will start to
flash.
The amplifier will remember the last mode it was in
after power off and revert to it the next time it is
powered on.
Preset
This is the factory default operation of the amplifier.
In Preset mode the position of all controls except
Master Volume (13) are stored within each channel.
Each channel should be considered a preset.
Selecting a channel automatically recalls the settings
stored within the channel. Note: The physical position
of the front panel controls, except Master Volume (13)
which is not storable, will now not match the actual
settings of the amplifier. All front panel switches will
automatically update.
Altering a control will cause the associated
parameter to jump to the current physical position of
that control.
When a control is altered the selected channel light
(3 or 5) will start to flash indicating that the current
preset has been altered.
To store the updated settings, push the Store switch
(12).
If you select another channel without pressing Store
(12) then any altered settings will be lost as the new
channel and its settings are recalled.
Manual
In manual mode the amp’s settings always match
the physical positions of the controls.
Changing channel only changes the channel, NO
presets are recalled, NO other controls are altered.
Pressing Store (12) will store the current settings into
the selected channel. These can then be recalled
when using the unit in Preset mode.
When channel settings have been stored the current
channel light (3 or 5) will stop flashing indicating the
preset has been saved.
Reverb & FX
The amplifier provides two simultaneous digital
effects, Reverb (Studio or Spring) and one of five FX
(Chorus, Phaser, Flanger, Delay or Octave)
Reverb
The Reverb control (8) sets the amount of signal sent
to each of the two reverb options - Studio or Spring.
When the Reverb control (8) is set to ‘0’ the reverb is
switched off, the status of the reverb is also indicated
on the optional footcontroller.
FX
The FX control is essentially split into five segments and
selects the type of FX and adjusts its associated
settings - except in the case of Octave which has a
single setting option. When the FX control is set to ‘0’
the FX are switched off, the status of the FX is also
indicated on the optional footcontroller.
Tap Tempo
The Tap Tempo switch (10) is used for the Delay effect
only.
The Tap Tempo switch matches the delay time to the
time between two presses.
The Tap Tempo LED flashes red at the
selected/recalled delay time.
The number of repeats is reduced as the delay time
decreases.
If you change from a channel with delay to one
without delay the effect will spill between channels.
If you change from a channel with delay to a
channel with delay set to a different delay time the
delay effect will not spill between channels.
MP3 / Line In
The 3.5mm MP3 / Line In socket (14) allows the
connection of an external audio source e.g. MP3 or
CD player.
