The DSA-4 stand adapter allows the mounting of up to three DVA T8 modules or one T12 module on a spacer rod. In combination with an S1518N subwoofer, the DSA 4 can also be used as an ,under-frame' for flown arrays to be fixed to the truss using a pipe and double coupler, and thanks to integrated feet, the DSA 4 can also be used as the basis for two to three DVA modules, for example, if they are to be set up on the stage edge.
