Front Panel; Master Section - Marshall Amplification Acoustic Soloist AS80R Handbook

Also included are stereo line-outs, for direct
linking to larger sound re-inforcement systems,
an effects loop with mono send and stereo return
jacks and Reverb/ Chorus footswitch jack.
Speaker complement.
To help ensure that the Acoustic Soloist's
sound remains warm and natural, we've used two
specially voiced Celestion 10" speakers that have
extended low and high frequency response with a
flat mid-range. This means that the sound always
has superb clarity and dynamic response even at
high volume levels. Also a piezo type dome
tweeter provides all the high-end crispness you
could ever need.

Front Panel

Channel 1 -Microphone.
1. XLR -Balanced input.
Input to mic, pre-amplifier.
2. Phase switch.
Reverses the phase of channel 1 only -to
prevent frequency cancellation problems when
mic'ing an instrument in conjunction with a pick-
up device through another channel.
3. Active Volume/ gain control.
For optimum headroom/ noise performance
controls the channel gain level.
4. 3 Band active EQ.
Provides cut and boost of + or -12 dB at
80 Hz (lo), 600 Hz (mid) and 8 KHz (hi).
5. Chorus in/ out push switch.
Selects the chorus in or out of this channel.
Channel 2 -Magnetic Auxiliary.
6. Jack input.
Jack input of approximately 10 Meg input Z.
7. Shift push switch.
Selects flat response for acoustic and tailored
response for electric guitar.
8. Active Volume/ Gain control.
Controls the channel gain level.
9. 3 Band Active EQ.
Provides cut and boost of + or - 12 dB at
80 Hz (lo), 600 Hz (mid) and 8KHz (hi).
10. Chorus in/ out push switch.
Selects the chorus in or out of this channel.
Channel 3 -Transducer.
11. Jack input.
With source select pushswitch for piezo or
pre-amped input. Piezo -10 meg input. Pre-amp -
100K input.
12. Active Volume/ Gain control.
Controls the channel gain level.
13. FB1 & FB2 Anti-Feedback filters.
Very narrow notch filters centered on the two
frequency bands normally problematic with
acoustic guitars.
14. Pick Attack control.
Centre off control to add or subtract the
higher harmonics of the signal to either remove
pick noise or accentuate these frequencies when
utililising finger style playing.
15. Pedal Level Effects Loop.
(Pre gain and EQ) Effects loop to match
floor pedals. 1 meg Ohm return impedance to
prevent interaction with swell pedals.
16. Fixed EQ.
Sweepable mid range circuit + or -12dB,
250Hz to 2K5Hz.
17. Low and high active E.Q.
Provides cut and boost of + or -12 dB at
80 Hz (lo) and 8 KHz (hi).

Master Section.

18. Mix control.
Controls the level of effects/ dry signal when
using external effects processors through the
effects loop.
19. Stereo Reverb.
With depth control, footswitchable with LED
status indicator.
20. Output volume.
Controls the overall output volume level.
21. Stereo Chorus.
Front panel on/ off switch for Stereo Chorus
with LED indication. Note:( this item is also
footswitchable (see item 23).
For the footswitch to function the panel
switch should be pushed to the'in' position.
