Marshall Amplification JVM410H User Manual

ENGLISH
CRUNCH GREEN MODE: This mode shares
the preamp topology of the classic Mar-
shall JTM45/1959 Plexi™ models
(i.e.: gain + gain + tone) but with a bit more
gain than is found in the originals.
CRUNCH ORANGE MODE: This mode is
reminiscent of the JCM800 2203 amplier,
a staple of hard rock. The gain structure is
gain + gain + gain + tone.
CRUNCH RED MODE: This shares the topology
of the orange mode, but with more gain,
giving you sounds similar to a hot-rodded
JCM800.
4. OD1 CHANNEL
OD1 GREEN MODE: This is very similar to
the hot-rodded JCM800 sound found in
crunch red mode, allowing you to dial-in
two disnctly dierent yet similar crunch
sounds if you so wish - one in each channel.
OD1 ORANGE MODE: This adds another gain
stage to the OD1 green mode, resulng in
a sound that’s perfect for singing leads and
hard rock/heavy metal tones.
OD1 RED MODE: Adds more gain to the OD1
orange for a high gain Marshall sound.
5. OD2 CHANNEL
This channel is similar to the OD1 channel
but with even more gain and a slightly
dierent tone network with the middle
control shied down to being centred
around 500hz instead of the more typical
Marshall value of 650hz. The result is 3
high gain modes that are ideal for both lead
and modern rhythm metal tones.

6. REVERB
Pressing the REVERB buon switches the
reverb ON and OFF in the current channel.
Each channel has its own reverb control
allowing individual channel reverb level
sengs: RVB CLEAN, RVB CRUNCH, RVB
OD1 and RVB OD2.
7. MASTER 1 / MASTER 2
These are the master volume controls
of the amplier. They can be assigned
individually to each of the modes as you
wish and their seng will be remembered.
8. PRESENCE AND RESONANCE
These controls are power-stage funcons
and only have eect when playing through
a speaker (not in SILENT RECORDING).
They aect how the power amplier reacts
to the connected speakers and how much
control the amplier has over them.
Increasing the RESONANCE control
emphasises speaker resonance for an
improved bass response and lower-end
thud. In the same way, increasing the
PRESENCE control emphasises the
speaker’s higher frequencies, making the
sound brighter and more ‘present’.
PRESENCE and RESONANCE constute
a powerful power-stage EQ, allowing
responses from a ‘
’ shape when they are
fully o, which is felt as a mid-boost, to a
‘v’ shape when they are turned clockwise,
giving a more scooped sound. Again, the
eecveness of these controls is highly
dependent on the kind of connected
speakers. Care has to be taken to avoid
over excursion of the speaker cones in high
resonance sengs.
9. FX LOOP
Pressing the FX LOOP buon switches
the FX loop ON and OFF in the current
channel.
The FX loop is programmable and features
a MIX control on the rear panel. The FX
