This compact and highly portable combo features two channels, each of which has its own independent volume and tone controls. A variety of inputs give the AS50D the ability to handle all-comers: the high-impedance input on Channel 1 is perfect for piezo or magnetic pickups. Channel 2 boasts RCA phono inputs plus a balanced phantom-powered XLR-type input in addition to its jack input, making it the perfect host for voice, instrument, or even backing track. The AS50D also contains a high-quality digital effects section featuring an adjustable Chorus which can be assigned to either or both channels, also a reverb. It also has a parallel Effects Loop that can be balanced between the two channels.
