Footswitch - Marshall Amplification JVM 4 Series User Manual

ENGLISH
4 channel JVM amps are supplied with a
6-way programmable footswitch which can
be connected to the amp via any standard
guitar cable.
Warning: the supplied footswitch lead is
unscreened and not suitable for guitar.
The footswitch features 7 LEDS marked clean,
crunch, OD1, OD2, master, reverb and FX. The
LEDs for each of the 4 channels are 3-coloured
green, orange and red. These indicate which
channel and mode is selected, alongside the
status of master, reverb and FX loop.
Each of the individual footswitches has 2
modes of operation:
Switch store mode: Assign any of its 6
•
switches to instantly recall any front panel
function (channel/mode; reverb on/off;
master volume 1/2 and FX loop on/off).
Note: if a switch is assigned to select a
channel, once it has been activated it can
be used to scroll through the three modes,
just like its respective front panel switch.
Preset store mode: Each switch can

be programmed to instantly call up a
combination of JVM button options to

form a preset. This allows you to recall
complete channel setups in any order and
combination.
As the switches can be programmed
independently you can program a mixture of
the above.
Note: all the settings are stored within your
footswitch; this means it can be plugged into
any JVM amp and all your footswitch settings
can be instantly recalled.
PROGRAMMING THE FOOTSWITCH
To enter footswitch program mode, press
the footswitch/MIDI program button on
the front panel once. The indicator light will
illuminate. This mode allows you to program the
footswitch.
Note: when the front panel footswitch/MIDI
program switch is off, the footswitch will
execute commands the moment the switch is
pressed down. When the footswitch program
mode is active, you can use the amp as normal
with commands executed on release of the
footswitch.
To store the current amp status/settings to a
footswitch (preset store mode):
1. Press the footswitch/MIDI program
button on the front panel to enter
Footswitch program mode (red LED).
2. Press and hold the desired footswitch for
about 3 seconds. The FX footswitch LED
will flicker indicating that the preset has
been stored.
To store a specific front panel function to a
footswitch (switch store mode):
1. Press the footswitch/MIDI program
button on the front panel to enter
Footswitch program mode (red LED).
2. Press and hold the desired footswitch.
While holding the footswitch down, in
less than 3 seconds, press the front panel
switch you want to map. The FX footswitch
LED will flicker a couple of times indicating
that the switch has been mapped.
Note: the footswitch/MIDI program switch
cannot be assigned to a footswitch.
The footswitch can be hot-swapped and
synchronises itself with the amp after
connection. Connect the footswitch lead to the
footswitch side first and then connect it to the
amp.
