Midi Operation - Marshall Amplification JVM410H Owner's Manual

FRONT PANEL FUNCTIONS (CONT.)
e) From now on the selected button will act
exactly in the same way as if you press the
related front panel button.
Front panel buttons and presets can be
assigned as wished without limitation
and in any order (again, except the
FOOTSWITCH / MIDI PROGRAM switch).
The footswitch's configuration is stored
within the footswitch itself, not in the
amplifier. Resetting the amplifier will not
affect the footswitch configuration as well.
The footswitch can be hot-swapped
and synchronises itself with any JVM4
amplifier after connection. However it is
recommended to connect the footswitch
lead to the footcontroller first and then
connect it to the amplifier.

MIDI OPERATION

Pressing the FOOTSWITCH / MIDI
PROGRAM button twice puts the amplifier
in MIDI waiting mode; the LED will
flash until a valid MIDI program change
command is received.
On reception of a MIDI program change
command the amplifier stores the current
status (channel + FX + reverb + master
settings) in the MIDI program number
received. It is possible to store up to 128
different MIDI presets.
To exit this status without waiting
for incoming MIDI data press the
FOOTSWITCH / MIDI PROGRAM button
again.
By default the amplifier is configured to
listen to MIDI channel #1, but it can be
changed to listen to any of the 16 MIDI
channels as follows:
a) Switch the amplifier power off (POWER
switch, not STANDBY).
b) Press and hold the FOOTSWITCH /
MIDI PROGRAM button.
c) Switch the amplifier power on.
d) Release the FOOTSWITCH / MIDI
PROGRAM button, the LED will start to
flash.
e) Send any MIDI command using your
MIDI pedalboard or any other MIDI
equipment.
f) The amplifier will detect which channel
came in and configure itself to listen to that
MIDI channel only.
g) From now on any MIDI preset you had
previously stored will be activated only
on the new channel regardless of what
channel you used before, this allows a fast
reconfiguration should there be a MIDI
conflict with any other outboard equipment.
Note: If you want to exit the MIDI channel
selection without any action press the
FOOTSWITCH / MIDI PROGRAM button
while waiting for MIDI data.
11. STANDBY & SILENT RECORDING
The STANDBY switch is used in
conjunction with the POWER switch to
'warm up' the amplifier before use and to
prolong the life of the output valves.
When the amplifier is in STANDBY (OFF)
the whole preamp section continues
running at its nominal voltages whilst the
power-stage remains in a 'standby' status.
This allows the amplifier to be used for
silent recording or for preamp purposes
using the EMULATED LINE OUT (Rear
Panel Function #16).
