Marshall Amplification 350 Stereo Amplifier User Manual


 
ATTITUDE, STUNNING GOOD LOOKS and
an incredible 350 Watts of brutal yet toneful
power set the MODE FOUR apart from
all
other amps. Add to this an arsenal of great
sounds, a slew of professional features plus
groundbreaking, state-of-the-art hybrid
technology and you have a Marshall like no
other.
You Spoke, We Listened . . .
The first ever Marshall, the legendary JTM45,
was born in 1962 as a result of the Guv’nor, Jim
Marshall, listening to what guitar players
wanted. Forty years later, the song remains the
same and that’s how the MODE FOUR came
to be. Modern guitarists told us they wanted an
amp capable of more gain, more low-end and
more headroom than ever before . . . plus great
cleans and, of course, the crunch tones that
have made Marshall a legend! We listened and
reacted – the result is the MODE FOUR.
Dual Amplifier Design
Countless amplifiers have claimed to offer both
classic and modern tones but, in truth, have
fallen well short of the mark. The MODE
FOUR boasts a true ‘Two Amplifiers in One’
design. AMP 1 (Classic) takes you from
shimmering clean to front-ended 2203 crunch,
while AMP 2 (Modern) takes you into modern,
extreme gain territory. To make this possible,
not only do AMP 1 and AMP 2 have totally
separate valve pre-amp circuits, the MODE
FOUR’s power amplifier section completely
reconfigures itself depending on the AMP
selected.
AMP 1
Whenever AMP 1 is selected, the power amp
reconfigures to create the unmistakable sound
and feel of our world renowned, 100 Watt
Super Lead Plexi. Using this as a sonic
foundation, AMP 1 has the characteristic
Marshall openness and roar that have made
amps like the Plexi, 2203 and Silver Jubilee
2555, timeless classics. While AMP 1’s
CLEAN Mode produces incredibly dynamic,
three dimensional clean and bluesy crunch
sounds, its CRUNCH Mode unleashes the
unbridled aggression and bite of the JCM800
2203, but with levels of gain never imagined in
1981, when this acclaimed model was first
launched.
AMP 2
In terms of sheer gain, AMP 2 takes over
from where AMP 1 leaves off, with OD2
Mode offering more gain than any other
Marshall before. Thanks to the MODE
FOUR’s radical design, you retain maximum
control even at extreme gain settings and the
reconfiguration of its power stage for AMP 2
results in an awesome yet tight low-end
‘thump’.
High Headroom 350W Power Amplifier
Innovative, state-of-the-art technology delivers
350W of pure tonal power by exactly recreating
the parameters of an all-valve system. Due to
this unique design and incredibly high headroom,
AMP 2’s impressively wide bottom-end not only
has the sound and feel of an all-valve amp, it
also doesn’t lose definition at high stage
volumes – a problem that many all-valve amps
suffer from.
Presence and Resonance Controls
These two Master Section controls affect the
high and low frequency damping, exactly as in
an all-valve amplifier. These can be used in
conjunction with the tone controls to fine-tune
your sound.
Tone Matrix Switch
AMP 2’s Tone Matrix control completely
reconfigures the tone network for three
different middle frequency positions. Unlike a
parametric E.Q. the Treble and Bass controls
remain completely interactive with the Middle
control.
Scoop
The MODE FOUR has two separate Scoop
controls – individually fine-tuned to the voicings
of AMP 1 and AMP 2.
Tuner Mute Switch & Tuner Out Jack
This switch mutes the MODE FOUR for ‘silent’
tuning via the Tuner Out jack socket on the rear
panel.
Footswitchable Solo Level
The Solo Level control allows you to dial in a
global level boost for all Modes over and above
the Master Volume setting. This is activated via
the included footcontroller and can give a
volume boost of up to 6dB.
6 Way LED Footcontroller Included
This facilitates silent footswitching of the four
Modes, Solo Boost and Digital Reverb.
Digital Reverb
The footswitchable, built-in Digital Reverb
sounds incredibly natural. Each AMP has its
own Reverb Level control.
Series/Parallel Effects Loop
Acompletely transparent effects loop allows the
connection of external effects units. Using the
independent level controls for each AMP enables
you to vary the FX loop from series to parallel.
Two Emulated Line Outs –
1
4
and XLR
Thanks to our critically acclaimed speaker
emulation circuitry, these two outputs are perfect
for live and studio applications. This line-level
signal is pre-Master Volume so ‘silent’ recording
is possible.
