DPA Microphones SB0400 Stereo BoomThe lightweight DPA SB0400 Stereo Boom, with or without a shock mounted microphone holder, addresses the need for quick, precise, and repeatable ways to switch between AB, XY, ORTF, and DIN stereo principles. The markers indicate parallel microphones positioning plus 90 and 110 offset for XY an ORTF configurations. A central base with rotary joint allows the microphones to be angled equally. The stereo boom has hooks for suspending the boom in wires.
