If you want to use a heavier microphone with your Triad-Orbit IO Quick-Change mounting rig, then Sweetwater engineers recommend this IO-H2 Mounting Head. A step up from the original IO-H model, the IO-H2 features a standard 5/8" thread and a notched stainless steel hex post, which locks into your Triad-Orbit stand or IO-R IO Quick-Change receiver for added stability and weight handling. Don't take chances with your precious tube or ribbon mics - lock them into place with a Triad-Orbit IO-H2 Mounting Head.
