Headphones & Line Out

The 3.5mm Headphones socket (18) allows the connection of a pair of headphones. When a jack is inserted into the headphones socket the unit’s speaker is muted.

Additionally the Headphones 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 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.

MG50FX

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.

MG100FX 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.

MG100HFX 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 settings, replacing them with the factory presets.
