AVT150 & AVT150H Rear Panel Features
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) AVT150
There are two speaker jacksockets on the
AVT150. 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) AVT150H
The AVT150H has two loudspeaker
outputs. The one marked ‘Extension 8
Ω
’ is for
connection to a single 8 Ohm cabinet. The
output marked ‘Extension 8/4
Ω
’ 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 8
Ω
cabinets connected in
parallel = 4
Ω
3 Footswitch
For connection of the supplied Stage Foot
Controller (PEDL-00031). 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.
4 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.
