The Heil Sound DT-1 is a flush mount designed for use with PL2T, SB-2, and HB-1 boom arms, providing a fixed mounting solution for microphone stand setups in studio, streaming, podcast, and recording environments. It installs directly into a desk or tabletop surface using a required 1-1/2″ hole and secures from below with a washer and nut system, creating a stable attachment point without the need for clamp or c-clamp mounts. The integrated brass insert supports boom arms with a 1/2″ stem, allowing proper connection for compatible poles, rods, or articulating boom arm systems. Designed to fit surfaces ranging from 1/2″ to 2″ thick, it functions as a low profile desktop base for mounted microphone holders and support arms used in audio, video, and content creation setups.
