Portable combo amplifier for acoustic instruments from A series that provides a range of acoustic-friendly controls and variables including digital reverb and chorus. At only 10.5kg it is very portable but can deliver the power and headroom for large stage performances. An ultra-efficient, dual mono Class D power amplifier is combined with a pair of 8" custom-designed dual-cone woofers to deliver articulate, transparent acoustic sound reproduction with both punch and high end clarity. The combo has two completely independent channel strips, both of which can accept either XLR or Jack inputs, provide 3-band equalization and feature a 'Shape' control for instant single button optimization. This flexibility allows for connection of a mic and instrument, two different acoustic instruments or even a blend of separate mic and pickup connections from the same instrument. On both XLR channel inputs, Phantom power is permanently available for use with a condenser or dynamic microphone Plus, with an additional Aux in connection for backing tracks, it is ideal for live performances. Both channels also feature their own Chorus and/or Reverb for further sound enhancement without the need for external effects units (both effects can be remotely bypass via FS2-MINI footswitch, not included). The unit has been designed to adapt to multiple performance situations. Placed on the floor it has a minimal stage footprint and can even be used as a performance seat in this position. Alternatively, it can be placed on its side feet for tonal variation or mounted on a speaker stand for maximum projection. A simple but very effective Anti-Feedback button can be engaged to automatically scan for and then eliminate unwanted feedback. A Phase switch is also on hand to remove of destructive interference which can occur when a player is too close to the amplifier. The combo further provides a balanced XLR D.I. out that provides direct, mic-free connection to a mixer or active speaker system for larger performance situations, and four digital EQ pre-sets that provide sound global enhancement options depending on situation and setup.
