Marshall JVM2 Serie Manual De Instrucciones página 5

For example, you could program a mixture of
switching functions (in our example switches #1
and #2 work in Preset Store mode, and #3 plus
#4 work in Switch Store mode), so that:
Footswitch #1 = Overdrive channel, green mode
with Master Volume ʻ 1 ʼ , Reverb ʻ o nʼ and FX loop
ʻ o ffʼ .
Footswitch #2 = Clean channel, red mode with
Master Volume ʻ 2 ʼ , Reverb ʻ o ffʼ and FX loop on.
Footswitch #3 = FX loop on/off
Footswitch #4 = Master 1/2
All the settings are stored within your footswitch;
this means it can be plugged into any JVM
amplifier and all your footswitch settings can be
instantly recalled.
Details on how to program your footswitch can
be found later in this manual.
III. Power Amp
The power amp stage of the JVMs is based on
the same as the one found in the JCM800 2203
and 1959 Superlead amplifiers and their 50W
cousins, responsible for the legendary Marshall
roar it has been adjusted to suit the variety of
tones found in the JVM. This section features
Presence and Resonance control to help shape
the overall tone of your JVM amplifier.
Your JVM is also equipped with a Silent
Recording mode. When the STANDBY switch is
OFF the power amplifier section is disabled but
the rest of the amplifier remains fully
operational.
IV. Studio Quality Reverb
The Marshall JVM is equipped with a studio
quality digital reverb routed in parallel to the
main signal and mixed by means of a valve.
When the reverb is engaged no degradation of
the direct signal occurs and when off it is
effectively removed from the circuit. Each of the
JVMʼ s channels also has its own dedicated
Reverb level control.
The Reverb switching has been designed to
avoid abrupt cut offs in the reverb tail so when
changing from channel to channel or switching
the reverb off, its tail naturally decays.
