The ST4, consists of four sliding microphone mounts with 5/8" male thread adapters and one articulated 5/8" female thread support that fits a mic stand, all sliding on a 30 cm (12") long hexagonal rod.
This allows the mounting of four mics on the same stand with variable distance and angulations between them.
Due to SABRA's modular system, the 12"long rod can be used to support some extremely long mic (SHOTGUNN), connecting the SSM-1/ANC spare rings, available at SABRA's products retailers.
