MAINS INPUT & FUSE

The specic mains input voltage rating that

your amp has been manufactured for is

indicated on the rear panel of the amp. Your

amp is provided with a detachable mains

(power) lead, which should be connected to the

mains input socket on the rear panel of the amp.

The correct value and type of mains fuse is

specied on the rear panel of the amp. Never

attempt to bypass the fuse or t one of the

incorrect value or type.

Warning: your amp must be switched off and

disconnected from the mains electricity supply

before you check and/or change any fuse.

IMPORTANT SET UP INFORMATION

Follow the start-up procedures below to safely

switch on your amplier. The procedure differs

depending on whether you plan to run your

amplier into speaker cabinets or for silent

recording.

Warning: failure to comply with the following

points may damage your amp.

Using your amp with speaker cabs

1. Make sure the power handling rating of

the speaker cabinet(s) is/are equal to or

higher than the output power of the amp.

Connect the speaker cabinet(s) to the

correct impedance speaker output(s) on

the rear panel.

Note: only use speaker (unscreened)

cables to connect the cabinets.

2. Ensure both the power switch and standby

switch are switched off and set all master

volumes on the front panel to zero.

3. Connect the footswitch cable to the

footswitch and then connect to the

footswitch socket on the rear panel of the

amp.

4. Connect the supplied mains (power) lead

into the mains input on the rear panel rst

and then into an electrical outlet.

3.1

FRONT PANEL FUNCTIONS CONTINUED

The front panel is divided into 3 main sections:

channels, reverb and master. Each of the

channels has 3 modes which are differentiated

by the colour of the light in the button used to

change channel. These are green, orange or red

respectively.

1. POWER SWITCH

This turns the amp on and off.

2. STANDBY SWITCH

The standby switch is used in conjunction with

the power switch to warm up the amp before

use. Turn power switch on for 2 minutes before

switching standby on.

Set the standby switch to the off position

during breaks in performances.

Note: when the standby switch is off the amp

can be used without a load for silent recording.

See the ‘Using your amp for silent recording’

start-up procedure for more information.

3. FOOTSWITCH/MIDI PROGRAM SWITCH

This switch has a dual function:

1. Pressing it once will enter ‘footswitch

program’ mode. This is indicated by a solid

red light.

2. Pressing it twice will enter ‘MIDI program’

mode. This is indicated by a blinking red light.

See more information on these modes later in

this manual.

4. FX LOOP SWITCH

Engages/disengages the series/parallel FX loop

for the current channel.

Note: this switch does not affect the power

amp insert / series loop.

CHANNEL SECTION

Pressing a channel button has two functions:

• When pressing in the same channel it

cycles the gain modes: GREEN (lowest

gain level) > ORANGE > RED (highest gain

level)> GREEN etc. Each mode remembers

its own previous FX, reverb and master

settings.

• Coming from a different channel recalls

the last setting in the new selected

channel.

Note: when you leave and then reselect a

channel, it will automatically recall the last

active mode.

13. CLEAN/CRUNCH CHANNEL

Green mode: this is the cleanest of the three

modes. It uses a simple and straightforward

circuit keeping the signal as pure as possible. In

this mode the channel’s volume control is taken

out of circuit. This is the only JVM mode where

this happens.

Orange mode: this mode shares the preamp

topology of the classic Marshall JTM45/1959

‘Plexi’ models but with a bit more gain.

Red mode: with more gain than the orange

mode, this mode is reminiscent of the Marshall

JCM800 2203 amp, a staple of hard rock.

14. OVERDRIVE CHANNEL

Green mode: this is similar to the hot-rodded

JCM800 sound found in the red mode of the

clean/crunch channel. So, you can dial-in two

distinctly different yet similar crunch sounds if

you so wish - one in each channel.

Orange mode: this adds gain to the overdrive

green circuit, resulting in a sound that is perfect

for singing leads and hard rock tones.

Red mode: this mode has the highest amount

of gain, resulting in a fully distorted heavy metal

tone.

REVERB SECTION

The digital reverb is routed in parallel to the

main signal and mixed using a valve. The reverb

does not degrade the direct signal when

engaged and when off it is effectively removed

from the circuit.

10. REVERB SWITCH

Switches the reverb effect on or off for the

current channel.

Note: the reverb switching has been designed

to avoid abrupt cut offs when changing from

channel to channel or switching the reverb off,

so uses a tail that naturally decays.

11. REVERB CONTROL (OVERDRIVE CHANNEL)

Adjusts the level of reverb applied to the

overdrive channel.

12. REVERB CONTROL (CLEAN/CRUNCH

CHANNEL)

Adjusts the level of reverb applied to the clean/

crunch channel.

MASTER SECTION

The master volume controls set the overall

volume of the amp across all channels. Master 1

ENGLISH

and Master 2 can be assigned to any mode and

can be switched back and forth.

5. MASTER 1

Master 1 is used on all channels/modes by

default.

6. MASTER 2

To set a channel/mode to recall master 2, select

the channel and mode, push the master button

to engage master 2 and then switch out of the

mode. When you re-visit the mode, the amp

will automatically recall which master volume

control you were previously using.

7. MASTER SWITCH

Switch between master 1 and master 2 for

different volume settings on the same channel/

mode. The red led in the switch indicates that

master 2 is engaged. The light is off when

master 1 is engaged.

Note: pre-sets stored in the footswitch will

recall whether master 1 or master 2 was

selected. However, it will not recall the previous

level of the master volume control.

3.2

FRONT PANEL FUNCTIONS CONTINUED

9. PRESENCE

Adjusts the high frequencies of the power amp.

Increasing high frequencies adds more bite to

your sound.

8. RESONANCE

Adjusts the low frequencies of the power amp.

Increasing low frequencies adds more bottom

end giving you a fatter sound.

Warning: care should be taken to avoid over

exertion of the speaker cones in high resonance

settings.

Note: both the presence and resonance

controls are power amp controls and therefore

only have effect when playing through a

speaker.

15. INPUT JACK SOCKET

Connect your guitar here using a ¼” jack

instrument cable.

1. POWER INLET

The supplied mains power lead is connected

here. The mains input voltage rating that your

amp has been built for is shown on the rear

panel.

Warning: before powering on, ensure the

amp is compatible with the mains voltage of

the country that the amp is being used in. If

you have any doubt, please get advice from a

qualied person.

2. MAINS FUSE

Protects the amp and mains supply in the event

of a fault. The correct value of mains fuse is

specied on the rear panel.

SERIES/PARALLEL FX LOOP

This is a programmable FX loop located after

the pre-amp, right before the reverb and series

loop circuits. The FX Loop switch engages/

disengages this effects loop.

13. SERIES/PARALLEL FX LOOP: SEND

Connect your external FX equipment here

using a ¼” jack instrument cable.

12. SERIES/PARALLEL FX LOOP: RETURN

Return your signal from external FX equipment

here using a ¼” jack instrument cable.

11. SERIES/PARALLEL FX LOOP: FX LEVEL

Congure the loop for use with either professional

equipment (+4dBu setting) or with guitar level

effects like effects pedals (-10dBV setting).

10. SERIES/PARALLEL FX LOOP: MIX

CONTROL

Control the amount of effect that can be dialled

in with the mix control. When mix is set to wet,

all the signal goes through the external loop,

adding more direct (unprocessed) signal as you

turn it towards dry.

Note: if you do not connect any effect to the

series/parallel effects loop the mix control can

be used as an additional volume control in any

of the channels.

Warning: when mixing the wet and dry

signals the external effects processor’s output

should be congured to remove the direct

(unprocessed) signal. If the amp sounds thin

after connecting an external effect check that

no direct signal is being returned from the

processor’s output.

Note: if the FX loop is on and the mix control

is set to wet without an external processor

connected, the amp will be muted.

ADVANCED USES OF THE SERIES/PARALLEL

EFFECTS LOOP

• To have a tuner output mute the amp,

connect the tuner to the FX send and

select the clean channel. Turn the mix

control to wet and switch the FX loop on.

Store this preset and label it for example

as ‘tuner’. With this conguration it is not

possible to connect any other effect to the

loop.

• As the reverb circuitry is connected after

the parallel loop you can create presets

that affect an external preamp, including

reverb and/or selecting a different master

volume.

• To use a different preamp and combine it

with the JVM channels:

1. Connect the external preamp output to

the parallel loop return and turn the mix

to wet.

2. Connect the external preamp input with a

splitter to the amps input.

POWER AMP INSERT/SERIES LOOP

This is a passive loop connected right before

the master controls. It is a line level loop so it

is recommended to only use high headroom

devices to avoid signal degradation.

9. PRE-AMP OUT/SEND

Connect your external FX equipment here

using a ¼” jack instrument cable.

8. POWER-AMP IN/RETURN

Return your signal from external FX equipment

here using a ¼” jack instrument cable.

Note: you can plug an external preamp into this

return jack to override the JVM preamp section

and use the output power section only. The

Master controls and the emulated line out are

located after the series loop so it is still possible

to use those features when using an external

preamp.

Note: to use two heads simultaneously, the

suggested procedure is to:

1. Connect the ‘master’ head pre-amp out to

the ‘slave’ head power-amp in.

2. Switch the power-amp insert to active in

the ‘slave’ amp.

In order to track the master volume settings in

both heads it is suggested to use MIDI control

with both amps programmed in the same way.

4.1

REAR PANEL FUNCTIONS CONTINUED

ENGLISH

Connect the MIDI in of one of the amps to the

MIDI thru of the other and the pedalboard or

MIDI equipment to the remaining MIDI in.

7. BYPASS SWITCH

Engage/disengage the power amp insert/series

loop. This switch cannot be programmed.

6. EMULATED LINE OUT

This output sends signal to external equipment.

The signal is taken pre-master volume,

processed through a 4x12 speaker cabinet

emulator and electronically balanced.

Note: using the line out does not omit the need

for a load to be connected (unless the amp is in

silent recording mode).

5. FOOTSWITCH

Connect the supplied footswitch using any

standard ¼” jack instrument lead.

Note: using any other type of footswitch rather

than the one supplied will have no effect and

will be ignored by the amp.

14. SPEAKER OUTPUTS

1/4” jack speaker outputs. They are labelled

according to the corresponding cabinet setups:

• 1 x 16 Ohm: connect a 16Ω speaker cab.

• 1 x 8 Ohm / 2 x 16 Ohm: connect a single

8Ω guitar cabinet or two 16Ω cabinets.

• 1 x 4 Ohm / 2 x 8 Ohm: connect a single 4Ω

guitar cabinet or two 8Ω guitar cabinets.

Warning: although the amp has ve speaker

outputs, never attempt to connect more

speakers than rated. The safe combinations are

listed above. Any other speaker conguration

may stress or damage the amp.

4.2

REAR PANEL FUNCTIONS CONTINUED

ENGLISH

Note: the JVM only accepts incoming data and

it is not able to send any MIDI commands.

4. MIDI IN

Connect any external MIDI equipment to the

MIDI In DIN socket.

3. MIDI THRU

A copy of the signal from the MIDI In connector

is available on the MIDI thru socket to allow

daisy chaining of MIDI equipment.

STORING MIDI PRE-SETS

Pressing the ‘Footswitch/MIDI program’ switch

twice puts the amp in MIDI waiting mode.

The indicator light will ash until a valid MIDI

program change command is received.

When the MIDI program is changed and the

command is sent, the amp 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 pre-sets.

To exit this status without waiting for incoming

MIDI data press the ‘Footswitch/MIDI

program’ switch again.

Note: by default, the amp is congured to listen

to MIDI channel #1 but it can be changed to

listen to any of the 16 MIDI channels as follows:

1. Switch off both the standby switch and

power switch.

2. Press and hold the footswitch/MIDI

program switch and switch the power

switch on.

3. Release the footswitch/MIDI program

switch. The LED will start to ash.

4. Send any MIDI command using your MIDI

pedalboard or any other MIDI equipment.

The amp will detect which channel came

in and congure itself to listen to that

MIDI channel only. From now on any

MIDI pre-set you had previously stored

will be activated only on the new channel

regardless of what channel you used

before. This allows a fast reconguration

should there be a MIDI conict 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.

ENGLISH

2-channel JVM amps come supplied with a

4-way programmable footswitch which can

be connected to the amp via any standard ¼”

jack instrument cable.

Warning: the supplied footswitch lead is

unscreened and not suitable for guitar.

The footswitch features 5 LEDS marked clean /

crunch, OD, master, reverb & FX. The LEDs for

each of the 2 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 4

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.

• Pre-set store mode: Each switch can

be programmed to instantly call up a

combination of JVM button options to

form a pre-set. 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/sengs to a

footswitch (pre-set 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 icker indicating that the pre-set has

been stored.

To store a specic front panel funcon 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 icker a couple of times indicating

that the switch has been mapped.

Note: the footswitch/MIDI program switch

cannot be assigned to a footswitch.
