MG50CFX & MG101CFX / MG102CFX / MG100HCFX Overview
Channel Selection
The amplifier has 4 channels - Clean, Crunch, OD1 &
OD2.
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 Damping switch (17) down for at least two
seconds. When in manual mode the Store switch (19)
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 (16) 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
(16) which is not storable, will now not match the
actual settings of the unit. 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
(19).
If you select another channel without pressing Store
(19) then any altered settings will be lost as the new
channel and its settings are recalled.
Manual
In manual mode the amps 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 (19) 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 & Delay
The amplifier provides three simultaneous digital
effects: Reverb, Delay and any one of the five
offered on the FX control (Chorus, Phaser, Flanger,
Vibe or Octave).
Reverb
The Reverb control sets the amount of signal sent to
either one of the two reverb options - Studio or Spring.
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. 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.
FX Off
Speed increases and depth is reduced as
knob is turned clockwise.
Speed increases as knob is turned
clockwise.
Speed increases, feedback and depth are
reduced as knob is turned clockwise.
The speed of the modulation increases as
the control is turned clockwise.
When the FX control is turned fully clockwise
the Octave effect is engaged – producing
a simultaneous note a full octave lower than
the one being played.
Delay
Hi-Fi A high fidelity, digital delay so pure that each
individual repeat is identical to the original
note(s)
Tape This emulates the classic, analogue nature of a
tape echo, producing a warm, dark sounding
delay effect with each successive repeat
diminishing.
Multi A digital delay with multiple outputs (taps),
each having a different delay time.
Reverse As its name suggests, this emulates the
sound of a reverse or backwards delay –
usually created in a studio by reversing the
tape or track (i.e. playing it backwards)
Tap Tempo
The Tap Tempo switch (13) 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.
6
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 (24) on the rear panel
allows the connection of an external audio source
e.g. MP3 or CD player.
Headphones & Line Out
The 3.5mm Headphone socket (18) allows the
connection of a pair of headphones. When a jack is
inserted into the headphone socket the unit's speaker
is muted.
Additionally the Headphone socket (18) can also be
used as a Line Out to send the signal to an external
equipment e.g. A computer, digital recorder or mixer.
When a jack is inserted into the socket the unit's
speaker is muted providing 'silent recording'. The
unit's output can then be monitored directly from the
external equipment used.
Damping
The Damping switch (17) selects between the two
modes of power amp damping. When Damping is
off (LED off), the power amp response resembles the
feel of a classic power amp with emphasized middle
and limited bass and treble. Switching Damping on
(LED on) will boost the speaker resonances both in the
bass and high frequency ranges.
FX Loop
The FX Return socket (25) on the rear panel is used to
connect the OUTPUT of the effects processor or pedal
you are using in the effects loop.
The FX loop is series and set at instrument level so both
guitar FX or professional rack effects units can be
connected.
The FX Send socket (26) on the rear panel is used to
connect to the INPUT of the unit you are using in the
effects loop.
The FX loop is switched on and off via the Ext FX
switch (15) on the front panel.

Loudspeaker
ALWAYS USE A NON-SCREENED MARSHALL
APPROVED SPEAKER LEAD WHEN CONNECTING AN
EXTENSION CABINET TO THESE AMPLIFIERS.
MG50CFX
The single Loudspeaker socket (22) is used to connect
either the internal speaker or an external speaker
cabinet to the unit's power amp. When using external
cabinets ensure the total load impedance is equal to,
or exceeds, 8 ohms.
MG100CFX 1x12" & 2x12" Combos
The single Loudspeaker socket (22) is used to connect
either the internal speaker or an external speaker
cabinet to the unit's power amp. When using external
cabinets ensure the total load impedance is equal to,
or exceeds, 4 ohms.
MG100HCFX Head
The two Loudspeaker sockets are used to connect to
1 or 2 external cabinets. When using external cabinets
ensure the total load impedance is equal to, or
exceeds, 4 ohms.
Power
The Power switch (20) turns the amplifier on and off. If
current settings have not been stored they will be lost.
Restoring Settings - WARNING: ALL AMP &
FOOTSWITCH SETTINGS WILL BE LOST
To restore the unit to factory settings (see handbook
rear cover) you must hold the Store switch (19) while
powering on the amplifier. The Clean/Crunch (3) and
OD (5) lights will light orange. You can then release
the Store switch (19).
Resetting the amplifier will erase all user Channel
presets and all user Footcontroller allocations,
replacing them with the factory presets.
