We have been designing and building these camera/microphone accessories since 1997 and consistently rank throughout the world as one of the best and most popular solutions for the semi-pro and professional videographer. Our latest product, the DXA-SLR ULTRA, is a compact audio adapter that brings the power of pro audio to the latest HDSLR cameras – marrying professional sound with cinema video for a fraction of the cost.
