Marshall Amplification MG50DFX Stereo Amplifier User Manual


 
From Jim Marshall
I would like to personally thank you for selecting one of
my new MG range of combos – the MG50DFX 1x12" or the
stereo MG250DFX 2x12".
As a musician myself, I fully understand what it takes to
perform live in a band situation. In addition to talent,
dedication and a lot of hard work, you also need equipment
that will help you deliver the goods in each and every
playing situation you find yourself in. With this goal firmly in
mind, I set my experienced R&D team the task of designing
a new range of affordable MG amplifiers that will deliver the
tone you’re looking for at all volume levels – from quiet late
night practice to a full-blown live gig and all points in-between – in the way only a Marshall can.
Utilising groundbreaking new technologies, some of which were developed for our critically acclaimed
AVT range, the new MG Series raises the standard for what can be expected from a value-for-money
range of guitar amplifiers and defines a new benchmark. For example, the power amp section of your
new combo boasts FDD (Frequency Dependent Damping) – a radical new feature that is exclusive to
Marshall Amplification and accurately mimics the way our all-valve amplifiers interact with a
loudspeaker. As a direct result of FDD, your new MG50DFX/MG250DFX will give you a sound and feel
never before thought possible in such an affordable, non-valve amp.
The DFX (Digital Effects) featured in both the MG50DFX and MG250DFX have been custom voiced
by our in-house digital effects experts. Each one of the five effect types on offer (Chorus/Delay, Delay,
Chorus, Flange and Reverb) have been designed to emulate the much sought after warmth and feel of
analogue effects, but in a highly flexible digital format. Furthermore, a wide range of variations for each
effect are quite literally at your fingertips – merely tweaking the three DFX controls (Preset/Adjust & FX
Level controls for the Chorus/Delay, Delay, Chorus and Flange options; and a separate Level control for
the Reverb) on the front panel, will give rise to sounds that range from subtle to radical, while always
remaining both natural and musical.
Like all the amplifiers in the new MG range, state-of-the-art manufacturing and stringent quality control
procedures ensure that these combos meet the high standard of build you have come to expect from all
Marshall products. The MG50DFX and MG250DFX were completely designed and engineered at my
Headquarters in Milton Keynes, England.
Whether the MG50DFX or MG250DFX is your first ever Marshall, or is the latest addition to your
arsenal of amps, the tone, flexibility and feel of these compact, rugged combos is guaranteed to deliver
the goods – from bedroom to backstage to onstage!
I wish you every success with your new Marshall. Welcome to the family...
Yours Sincerely,
21
