The Triad-Orbit O2, Orbit 2, is the BEST double-arm boom stand ever made! It features ball-swivel mechanisms and double telescoping adjustable boom arms for precise placements and infinite adjustments. The comfortable industrial-grade clutches are incredibly strong and the all metal construction makes holding even heavy things easy. The Orbit 2 connects to any Triad-Orbit IO quick-change product for fast setup or with the optional IO-RA coupler you can use it with any stand you want! The Orbit 2 also has built in IO quick-change couplers that make switching out mics a breeze. Just push down on the couplers to release the IO-H1 standard 5/8″ microphone mounting heads (3/8″ adapters included) and snap them back in to use. The center also adjusts 150° for more placement options. This is the BEST double boom arm advanced stand system in the world!
