    Product Description

    The Marshall AS50D is a quality amplifier that has proven to be invaluable to a great many people. Whether you're a one man band performing at open-mic nights or even a duo, the AS50D is a good choice for those wanting to take their acoustic music to the stage. You get 2 channels (1 vocal and 1 instrument) with a variety of different inputs to accommodate your needs. You even get a stereo RCA input for external audio devices so you could play along with backing tracks, or play CD's during your set breaks!

    As everybody knows feedback can be harsh on the ear, and unfortunately with acoustic music it's more likely to happen too. With lower output that its big brother (The AS100D) that does include an Anti-Feedback System, it's possible you could push the amp a bit too hard to accommodate for the lower output. Having said that, the AS50D does have a D.I output so you could always feed that to a P.A System if need be.

    The AS50D is by no means quiet, and for more intimate performances or at home, the amp does perform as you would expect, with a clear and precise sound that's still nice and warm. Having said that, the AS50D does have a D.I output so you could always feed that to a P.A System if need be. Also featured are some great reverbs and chorus FX to add nice wobbles and echo's to your sound as required!

    Here's what Marshall say about the AS50R 50W Acoustic Guitar Amp

    The AS50D 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 AS50D 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 AS50D is loaded with two 8" speakers and a high fidelity polymer dome 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 AS50D is the ideal amplifier for the acoustic player who wants a system as suitable for small gigs as it is at home.
