Acoustic Soloist -AS80R.
Due to the increased popularity of acoustic
and electro/ acoustic instruments, a dedicated
amplification system that can accurately
reproduce the pureness of an acoustic's unplugged
sound is a must for many performers.
To amplify the subtle nuances and natural
characteristics of acoustic instruments requires an
amplifier of great flexibility and superb overall
tone.
The unique design and high versatility of the
Acoustic Soloist offers all this within its three
independent channels, each designed for a specific
purpose but with the flexibility to provide much
more -plus the ability for each channel to be used
simultaneously.
Channel 1 -Microphone.
Featuring a balanced XLR connector into a
studio grade pre-amplifier with active volume and
EQ controls.
A phase switch is provided to prevent
problems when linking an instrument in
conjunction with a pick-up device through another
channel.
The flexibility of this channel enables the use
of a microphone for either instrument or vocal
reproduction, making the Acoustic Soloist ideal
for the 'solo' performer playing small gigs, where
space is at a premium.
Channel 2 -Magnetic Auxiliary.
As well as being perfect for magnetic or piezo
type acoustic pick-ups, this multi purpose channel
is also ideal for inputing a backing tape or drum
machine.
A shift switch re-voices the channel to suit
clean, electric guitar and is excellent for jazz or

country style playing. This makes the Acoustic
Soloist the ideal amp for singers who also need to
play acoustic and electric rhythm guitar for their
backing.
Channel 3 -Transducer.
The main Transducer channel is intended for
piezo type acoustic transducers either direct from
the instrument or from pre-amped devices.
It's highly flexible features include active
volume and EQ, two specially designed anti-
feedback filters and a unique 'pick attack' control
which accentuates the contrast between plectrum
and finger picking styles.
It also has a 'pedal level' effects loop suitable
for connecting floor pedals such as delays,
compressors, swell pedals etc, exclusively through
this channel.
The Master Section.
The Acoustic Soloist boasts an 80 watt stereo
(40 watts per side) power amplifier specifically
designed for wide frequency response and low
distortion. Semi 'soft knee' limiting is included so
maximum headroom can be achieved cleanly
without any undue harshness.
The built in stereo reverb creates warm,
natural depth while Marshall's renowned
analogue chorus provides a stereo spread that adds
incredible width to the sound.

The Rear Panel.

The Acoustic Soloist features a 'Phase
Reversal' switch on the rear panel that will help to
eliminate one of the most common problems
associated with amplified acoustic instruments -
unwanted feedback and overtones. Furthermore, it
does so without compromising the tone in the
slightest.
