Marshall Amplification’s AS100D is a 50W 50W 2×8″ combo amp with 2 hi-fi plymer dome tweeters and was created for use with a variety of acoustic instruments. Between its 4 channels, the AS100D has the flexibility to handle instruments with piezo transducers or magnetic pickups, plus microphones, for both vocal and instrument reproduction. For those using 2 pick-ups via one stereo jack, the 2 main Acoustic Channels (1 and 2) can be linked together voa a “Link” switch, affording you independent Volume & EQ controls for each pick-up. The other 2 channels are a dedicated Microphone channel (3) and an Auxiliary channel (4), the latter of which has phono (RCA) stereo inputs specifically for use with external audio equipment. The AS100D houses an internal limiter to ensure you can achieve maximum output while your sound remains distortion-free.
Even though the AS100D’s 50W 50W stereo configuration offers more than enough power for many typical acoustic music venues, a stereo pair of balanced XLR DI outs and Line Outs allow you to connect directly to an external PA system for larger venues. To eliminate the problem of unwanted feedback, the AS100D features several anti-feedback controls, including an individual Phase switch on channels 1, 2 & 3, plus 2 frequency controllable Notch Filters with selectable extra depth for channels 1 & 2.
The amp’s 16 built-in adjustable stereo digital effects (10 reverbs, delay, chorus, etc.) add a new dimension to the already wide range of sounds the AS100D offers. Additionally, there is also a stereo Parallel Effects Loop, complete with Level Control, on the rear panel.
