From the Chairman
I would like to thank you personally for selecting the AS50R,
Acoustic Soloist combo.
The Marshall name has been associated with many fine products
over the years and our commitment to quality remains as constant
today as it did right back at the birth of Marshall Amplification back
in 1962.
In the case of the Acoustic Soloist, much time and research has
gone into making the sound as natural as possible. As all of my
designers are also guitarists, they fully understand the needs of the
player and bring their expertise to bear on all our products. You can
also rest assured that every Marshall amplifier has been designed
and engineered to the highest possible standards, so as a result will
stand the test of time and constant use.
I strongly suggest that you read this handbook carefully before
using your AS50R and then keep it on hand for future reference.
I am certain that you will get great enjoyment from your Marshall
Acoustic Soloist combo and wish you every success with it.
Yours Sincerely,
English

Introduction
The AS50R is a compact and portable 50 Watt combo amplifier specially designed for use with acoustic
instruments. Between its two channels, this combo has the flexibility to handle instruments with transducers, such
as piezo or magnetic pick-ups (channel 1), or microphone for either vocal or instrument reproduction (channel 2).
The built-in Chorus effect is assignable to either or both channels and the Reverb can be controlled and balanced
between the channels to create just the right ambience. If you want to add further effects, then there is an on-board
parallel effects loop which can be balanced between the channels in the same way as the Reverb.
One of the most difficult aspects of amplifying some acoustic instruments is feedback. To help you eliminate this,
the AS50R features several ‘anti-feedback’ controls, including a Phase switch and a frequency controllable Notch
Filter. The combination of these two elements will give you precise control of the frequencies where feedback is
likely to occur and help you to eliminate them.
For clear and detailed performance, the AS50R is loaded with two 8" speakers and a high efficiency piezo tweeter.
There is also an internal limiter which allows you to push the maximum level from the 50 Watt output, whilst
remaining distortion free.
Neat and compact, flexible and portable, the AS50R is the ideal amplifier for the acoustic player who wants a
system as suitable for small gigs as it is at home.
Front Panel Features
Channel 1 - Acoustic Instrument Channel
1. Input Jack
Plug the lead from your guitar in here. The high
impedance of this input will help you to get the
best from the passive or active piezo or magnetic
pick-ups.
2. Volume Control
Controls the volume level of the Acoustic Channel 1.
A good place to start with this control is the half
way, or 12 o’clock position, then adjust according
to the sensitivity of your pick-up.
3. Bass Control
Adjusts the amount of bass, or bottom end of the
instrument’s tone. Care should be taken when
setting this control as adding excessive bass can
cause unnatural howling. Again, the half way
position is the best place to start.
4. Treble Control
Adjusts the treble, or top end of your sound.
Careful adjustment will make your high notes lively
but not too harsh. It is worth noting that set in
higher positions, this control will induce a certain
amount of noise.
Channel 2 - Microphone / Aux Channel
5. Phono Inputs
Inputs to take connection from a tape or CD player.
6. Microphone Input
Balanced XLR type input for connection of a
microphone and suitable for vocal or instrument
applications.
7. Jack Input
Input to take any source, such as a drum machine,
keyboard, etc.
8. Volume Control
Controls the volume level of the Microphone / Aux
Channel 2. A good place to start with this control is
the half way, or 12 o’clock position, then adjust
according to the sensitivity of your pick-up
9. Bass Control
Adjusts the amount of bass, or bottom end of your
sound. Care should be taken when setting this
control as adding excessive bass can cause
unnatural howling. Again, the half way position is
probably the best place to start.
10.
Treble Control
Adjusts the treble, or top end of your sound.
Careful adjustment will make your high notes lively
but not too harsh. It is worth noting that set in
higher positions, this control will induce a certain
amount of noise.
Master Section
11. C
horus Assign Switches
Allows the built in Chorus effect to be selected on
either channel individually, or both channels
together.
12.
Chorus Speed Control
Controls the speed of change of frequency for the
built-in Chorus effect.
13.
Chorus Depth Control
Controls the amount of change of the frequency
shift for the built-in Chorus effect.
2 3
English
Note: When using the Chorus, higher speed
settings usually sound better with lower depth
settings and vice versa. Experiment to find which
selection suits you best.
14.
Reverb Balance Control
Controls the balance of the Reverb effect and the
parallel effects loop between Channel 1 and
Channel 2.
15.
Reverb Level Control
Controls the overall level of the Reverb effect.
16.
Phase Switch
Switching the phase can considerably reduce the
amount of low frequency acoustic feedback.
17.
Notch Filter Switch
Further feedback reduction can be achieved using
the selectable frequency notch filter. When
activated, the filter cuts by 10dB the frequency
selected using the rotary control (item 18).
18.
Frequency Control
If feedback occurs when the Master Volume is set
to the desired performance level, select the switch
(item 17) and rotate this control until the offending
frequency is eliminated.
19.
Master Volume
Controls the overall volume output from the
amplifier.
20.
Power Switch
This is the On/Off switch for the mains power to
the amplifier. When it is switched ‘On’, the switch
will light. Please ensure the amplifier is switched
off and unplugged from the mains electricity
supply before being moved.
Rear Panel Features
1. Mains Input
Your amp is provided with a detachable mains
(power) lead that is connected here. The specific
mains input voltage rating that your amplifier has
been built for is clearly marked on the back panel.
Before connecting for the first time, please ensure
that your amplifier is compatible with your
electricity supply. If you have any doubts, please
get advice from a qualified person. Your Marshall
dealer can help you in this respect.
2. Footswitch Jack
Jack socket for connection of the optional
footswitch (model PEDL-10029) for switching the
Reverb and Chorus functions on and off.
3. Line Out Jack
Jack socket for connection to home recording or
other external equipment with jack inputs.
4. DI Out
XLR type output for connection to PA or similar
external equipment.
Note: Both the Line Out and DI out carry exactly
the same signal at different levels and both are
placed before the Master Volume so changing the
overall level of the amplifier will not affect the
signal from the DI or Line Output.
5. Effects Send Jack
Jack socket to connect to the input of an external
effects processor.
6. Effects Return Jack
Jack socket to connect to the output of an external
effects processor.
