The front panel is divided into 3 main secons: channels, reverb and master. Each of the channels has 3 modes which are dierenated by the colour of the light in the buon used to change channel. These are green, orange or red respecvely.

This turns the amp on and o.

The standby switch is used in conjuncon 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 o posion during breaks in performances. Note: when the standby switch is o the amp can be used without a load for silent recording. See the ‘Using your amp for silent recording’ start-up procedure for more informaon.

3. FOOTSWITCH/MIDI PROGRAM SWITCH

This switch has a dual funcon:

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 informaon on these modes later in this manual.

Engages/disengages the serial/parallel FX loop for the current channel. Note: This switch does not aect the power amp insert / serial loop.

19. INPUT JACK SOCKET

Connect your guitar here using a ¼” jack instrument cable. CHANNEL SECTION Pressing a channel buon has two funcons:

• 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 sengs.

• Coming from a dierent channel recalls the last seng in the new selected channel. Note: when you leave and then reselect a channel, it will automacally recall the last acve mode.

Green mode: This is the cleanest of the three modes. It uses a simple and straighorward 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 mode where this happens. Orange mode: This mode oers a punchy sound that’s easy to overdrive. Red mode: This is mode adds another gain stage aer the tone stack.

This channel has a more typical Marshall preamp circuit characterisc of ‘gain then tone’. Green mode: This mode shares the preamp topology of the classic Marshall JTM45/1959 Plexi™ models (i.e.: gain + gain + tone). This means the sound and response will be similar to these vintage ampliers, but with a bit more gain than is found in the originals. Orange mode: This mode is reminiscent of the JCM800 2203 amplier and oers griy, . The gain structure is gain + gain + gain + tone. Red mode: This shares the topology of the orange mode, but with more gain, giving you sounds similar to a hot-rodded JCM800.

Green mode: This is very similar to the sound found in crunch red mode, allowing you to dial-inENGLISH

two dierent crunch sounds. Orange mode: This adds another gain stage to the OD1 green mode, resulng in hard rock/ heavy metal tones. Red mode:Adds more gain to the OD1 orange for a high gain Marshall sound.

This channel is similar to the OD1 channel but with even more gain and the middle control shied to being centred around 500hz (instead of the more typical Marshall value of 650hz). OD2 provides 3 high gain modes that are ideal for both lead and modern rhythm metal tones. 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 o it is eecvely removed from the circuit.

Switches the reverb eect on or o for the current channel.

13. REVERB CONTROL (CLEAN CHANNEL)

Adjusts the level of reverb applied to the clean channel.

14. REVERB CONTROL (CRUNCH CHANNEL)

Adjusts the level of reverb applied to the crunch channel.

11. REVERB CONTROL (OD1 CHANNEL)

Adjusts the level of reverb applied to the OD1 channel.

12. REVERB CONTROL (OD2 CHANNEL)

Adjusts the level of reverb applied to the OD2 channel. MASTER SECTION The master volume controls set the overall volume of the amp across all channels. Master 1 and Master 2 can be assigned to any mode and can be switched back and forth.

Master 1 is used on all channels/modes by default.

To set a channel/mode to use master 2, select the channel and mode, push the master buon to engage master 2 and then switch out of the mode. When you re-visit the mode, the amp will automacally recall which master volume control you were previously using.

Switch between master 1 and master 2 for dierent volume sengs on the same channel/ mode. The red LED in the switch indicates that master 2 is engaged. The light is o when master 1 is engaged. Note: presets 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.

Adjusts the high frequencies of the power amp. Increasing high frequencies adds more bite to your sound.

Adjusts the low frequencies of the power amp. Increasing low frequencies adds more boom end giving you a faer sound.

Warning: care should be taken to avoid over

exeron of the speaker cones in high resonance sengs. Note: both the presence and resonance controls are power amplier controls and therefore only have eect when playing through a speaker.ENGLISH

The supplied mains power lead is connected here. The mains input voltage rang that your amplier has been built for is shown on the rear panel.

Warning: before powering on, ensure the amp is

compable with the mains voltage of the country that the amp is being used in. If you have any doubt, please get advice from a qualied person.

Protects the amplier and mains supply in the event of a fault. The correct value of mains fuse is specied on the rear panel.

A copy of the signal from the MIDI In connector is available on the MIDI thru socket to allow daisy chaining of MIDI equipment.

Connect any external MIDI equipment to the MIDI In DIN socket. SERIAL/PARALLEL FX LOOP: This is a programmable FX loop located aer the pre-amp, right before the reverb and serial loop circuits. The FX Loop switch engages/disengages this eects loop.

13. SERIAL / PARALLEL FX LOOP: SEND

Connect your external FX equipment here using a ¼” jack instrument cable.

12. SERIAL / PARALLEL FX LOOP: RETURN

Return your signal from external FX equipment here using a ¼” jack instrument cable.

11. SERIAL / PARALLEL FX LOOP: FX

LEVEL Congure the loop for use with either professional equipment (+4dBu seng) or with guitar level eects like eects pedals (-10dBV seng).

10. SERIAL / PARALLEL FX LOOP: MIX

CONTROL Control the amount of eect 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.

POWER AMP INSERT/SERIAL 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 degradaon.

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.

Engage/disengage the power amp insert/serial 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).

Note: using any other type of footswitch rather than the one supplied will have no eect and will be ignored by the amp.

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 amplier has ve

speaker outputs, never aempt to connect more speakers than rated. The safe combinaons are listed above. Any other speaker conguraon may stress or damage the amp. 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 operaon:

• Switch store mode: Assign any of its 6 switches to instantly recall any front panel funcon (channel/mode; reverb on/o; master volume 1/2 and FX loop on/o). Note: if a switch is assigned to select a channel, once it has been acvated it can be used to scroll through the three modes, just like its respecve front panel switch.

• Preset store mode: Each switch can be programmed to instantly call up a combinaon of JVM buon opons to form a preset. This allows you to recall complete channel setups in any order and combinaon. As the switches can be programmed independently you can program a mixture of the above. Note: all the sengs are stored within your footswitch; this means it can be plugged into any JVM amp and all your footswitch sengs can be instantly recalled. FOOTSWITCHENGLISH

PROGRAMMING THE FOOTSWITCH

To enter footswitch program mode, press the footswitch/MIDI program buon 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 o, the footswitch will execute commands the moment the switch is pressed down. When the footswitch program mode is acve, you can use the amp as normal with commands executed on release of the footswitch. To store the current amp status/sengs to a footswitch (preset store mode):

1. Press the footswitch/MIDI program buon

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 indicang that the preset has been stored. To store a specic front panel funcon to a footswitch (switch store mode):

1. Press the footswitch/MIDI program buon

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 mes indicang 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 aer connecon. Connect the footswitch lead to the footswitch side rst and then connect it to the amp. FOOTSWITCH RESET
