Advantage being it is mounted under the camera sandwiched between cam and tripod. Takes up little room. Handles the preamp of the sound so cam's preamp can be turned down. Very good headphone monitoring. Does have RTN plug if you want to check for output from cam.
Way better than beachtek in every way. Will outlast your cam. Does not beat double system but does give you a neat package for run and gun.
