1. Mains Input Connector

Your AVT is provided with a detachable mains

(power) lead which is connected here. The

specific mains input voltage rating that your

amplifier has been built for is shown on the back

panel. Before connecting for the first time,

please ensure that your electricity supply is

compatible with your amplifier. If you have any

doubt, please seek advice from a qualified

technician. Your Marshall dealer will help in this

respect.

2. Loudspeaker Jack Sockets

a) AVT150X

There are two speaker jacksockets on the

AVT150X. The one marked Internal (8 Ohm) is

where the output of the AVT power amplifier is

connected to its internal 8 Ohm Celestion

loudspeaker.

When an extension speaker is connected to the

other output (marked Extension) the full power

of the 150W power amplifier is unleashed.

Please note that only an extension cabinet rated

at 8 Ohms should be used.

This will provide a parallel load with the Internal

Speaker of 4 Ohms minimum.

b) AVT150HX

The AVT150HX has two loudspeaker outputs.

The one marked ‘Extension 8Ω

’ is for

connection to a single 8 Ohm cabinet. The

output marked ‘Extension 8/4Ω’ can either be

used for connection to a second 8 Ohm speaker

cabinet, or to drive a single 4 Ohm cabinet.

WARNING:

Always provide the AVT with a load equal to, or

greater than, 4 Ohms.

Note: Two 8Ω cabinets connected in

parallel = 4Ω

3. Footswitch

For connection of the supplied Stage Foot

Controller (PEDL-10031). This sturdy 6-way

Marshall footswitch allows instant selection of

the 4 channels, plus the two DFX modes. It also

features LEDs to indicate status.

Headphones

The headphones output is fully emulated using

an improved version of the circuitry found on the

industry standard JMP-1. Turning the Master

Volume (20) to zero will provide silent practice.

5. Emulated Line Output

This jack socket carries a specially treated

output signal from your AVT that accurately

emulates the sonic signature of a Marshall 4x12

cabinet. This unerringly accurate emulation

circuitry is Marshall's most advanced to date

and was developed via countless hours of

technical research, playing, listening and fine-

tuning. This output can be used in both live

performance and recording situations to achieve

authentic guitar amp tones, without having to

use a microphone. Turn down the Master

Volume (20) for silent recording.

FX Loop

As already mentioned, the AVT150X and

AVT150HX both boast a Mono Parallel FX loop

for connection with external effects units. In

addition to the FX Mix controls on the front

panel (see ‘Front Panel Features’, point 22) this

FX loop comprises of an FX Send jack, an FX

Return jack and an FX level control button.

6. FX Return

For connection to the output of your external

effects device.

7. FX Level

This should be set to match the level of the

processor being used (generally -10dB for a

stomp box, +4dB for a professional, rack unit).

8. FX Send

For connection to the input of the external

device being used.

* FX Loop Hints:

a) Always use high quality, shielded patch

cables.

b) If the processor being used has an input level

control, ensure it is set correctly.

c) Time based effects (delays & reverbs) and

modulation effects (chorus, flange, phase, etc.)

are ideal for use in a Parallel FX loop.

d) Certain stomp box effects such as Wah,

distortion, overdrive and fuzz were designed

specifically for use in front of the amp and sound

best when used that way. This said, tonal beauty

is in the ears of the beholder so, if such a pedal

sounds great to you when used in an FX loop

then go for it! Sometimes, there are no rules...

2. Loudspeaker Jack Sockets

These connect the internal loudspeakers to the

stereo power amplifier outputs.

WARNING:

Always provide both with a load equal to, or

greater than 8 Ohms.

3. Footswitch

industry standard JMP-1. Turning the Master

Volume (20) to zero will provide silent practice.

5. Emulated Line Outputs (L, R)

This pair of stereo jack sockets carries a

specially treated output signal from your AVT

that accurately emulates the sonic signature of a

Marshall stereo 4x12 cabinet. This unerringly

accurate emulation circuitry is Marshall's most

advanced to date and was developed via

countless hours of technical research, playing,

point 22) this FX loop comprises of an FX Send

jack, two FX Return jacks, Left & Right, and an

FX level control button.

6. FX Return Left & Right

For connection with the stereo output of your

external effects device - left goes to left and,

wait for it, right goes to right.

Note: when using a mono output device use the

Right (R) FX return as indicated.

7. FX Level

This should be set to match the level of the

processor being used (-10dB for a stomp box,

+4dB for a professional, rack unit).
