Channel Section

Pressing a channel button has two functions:

When coming from a different channel it recalls

the last setting in the new selected channel.

When pressing in the same channel it cycles the

modes: GREEN > ORANGE > RED > GREEN...

Each mode remembers the FX, Reverb and

Master settings.

Example: You are in OD1 ORANGE with FX +

REVERB and you press CLEAN. The amp

switches to the last Clean mode you had (let's

assume it was CLEAN GREEN with REVERB).

If you press the OD1 switch you go back to OD1

ORANGE with FX + REVERB. This allows

bouncing between channels without losing the

settings. If you now press OD1 again, you go to

OD1 RED with whatever FX, MASTER and

REVERB settings you had last time you were in

this mode.

Pressing REVERB switches the reverb ON and

OFF in the current channel.

Pressing FX LOOP switches the parallel FX loop

ON and OFF in the current channel.

Master Section

5. REVERB Control

Alongside the REVERB switch each channel

has its own reverb control allowing individual

level settings of the effect.

6. MASTER 1 / MASTER 2

These are the master volume controls of the

amplifier. They can be assigned individually to

each of the modes as you wish and their setting

will be remembered in each of the modes.

7. PRESENCE, RESONANCE

These controls are power amplifier controls and

only have effect when playing through a speaker

(not in silent recording). They affect how the

power amplifier reacts to the connected

speakers and how much control the amplifier

has over them.

Increasing the RESONANCE control

emphasises the natural speakers resonance for

an improved bass response. In the same way,

increasing the PRESENCE control emphasises

the speaker’s high frequencies which will be

heard as an improved high frequency response

which adds presence to the sound.

Presence and Resonance constitute a powerful

power amplifier equaliser, allowing responses

from a ‘^’ shape when they are fully off, which is

felt as a mid boost, to a ‘v’ shape when they are

turned clockwise, which is felt as a scooped

sound. Again, the effectiveness of these controls

is highly dependant on the kind of connected

speakers. Care has to be taken to avoid over

excursion of the speaker cones in high

resonance settings.

8. FX LOOP

This is a programmable FX loop which features

a MIX control on the rear panel and it is located

after the pre-amp, right before the reverb and

serial loop circuits. Pressing the FX Switch

engages this effects loop. Please refer to the

Serial / Parallel Loop description later on in the

handbook for its operation.

9. FOOTSWITCH / MIDI PROGRAM

This switch has a dual function:

Pressing it once we enter the FOOTSWITCH

PROGRAM mode. It is indicated by a

continuous red light.

Pressing it twice we enter the MIDI PROGRAM

mode. It is indicated by a blinking red light.

Footswitch program and use

The JVM range features a new type of fully

configurable footswitch. Connection to the

amplifier requires a standard mono 1/4" jack to

jack cable. Any guitar lead will work and

practically there should be no limit in its length.

When the front panel FOOTSWITCH / MIDI

PROGRAM switch is off, the footswitch operates

in safe mode and executes the commands the

moment the switch is pressed down.

If you enter the FOOTSWTICH PROGRAM

mode (LED red) you will be able to program the

footswitch but nevertheless the footswitch and

the amplifier will remain fully operational with the

only difference that the commands will be

executed when releasing the footswitches, as

opposed to the normal mode.

Each of the individual footswitches has 2 modes

of operation: preset store and switch store.

In preset store mode, any of the footswitches

can be configured to store the current amplifier

status. The current channel, master, FX and

reverb status will be stored and recalled when

the respective footswitch is pressed.

To store the current status simply:

Set the amplifier to FOOTSWITCH PROGRAM

mode (red light ON).

Press and hold the desired switch for about 3

seconds.

The FX footswitch LED will flicker a couple of

times indicating that the preset has been stored.

In switch store mode, any of the footswitches

can be configured to replicate the front panel

switches and the amplifier will react exactly in

the same way as when you operate them on the

front panel.

All the front panel switches can be mapped to

any of the footswitches without any limitation.

The only exception is the FOOTSWITCH / MIDI

PROGRAM key which cannot be assigned to

the footswitch.

To assign any of the front panel keys (except

FOOTSWITCH / MIDI PROGRAM) to any of the

footswitches simply:

Set the amplifier to FOOTSWITCH PROGRAM

mode (red light ON).

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.

From now on the selected footswitch will act

exactly in the same way as if you press the

related front panel switch.

Keys and presets can be assigned as wished

without limitation and in any order (again, except

the FOOTSWITCH / MIDI PROGRAM key). The

footswitch configuration is stored in 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 the amplifier after

connection. However it is recommended to

connect the footswitch lead to the footswitch

side first and then connect it to the amplifier.

MIDI operation

Pressing the FOOTSWITCH / MIDI PROGRAM

switch 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 switch again.

Note about MIDI channels: 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:

Switch the amplifier off (Power switch, not

Standby).

Press and hold the FOOTSWITCH / MIDI

PROGRAM switch.

Switch the amplifier on (Power switch).

Release the FOOTSWITCH / MIDI PROGRAM

switch, the LED will start to flash.

Send ANY MIDI command using your MIDI

pedalboard or any other MIDI equipment.

The amplifier will detect which channel came in

and configure itself to listen to that MIDI channel

only. 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.

If you want to exit the MIDI channel selection

without any action press the

FOOTSWITCH / MIDI PROGRAM switch while

waiting for MIDI data.
