The ST2, consists of two 5/8" male thread devices and one articulated 5/8" female thread support, all sliding on a 20 cm. long hexagonal rod. This allows the mounting of two mics. on the same stand with variable distance and angulation between them.

The ST2 can be used to support 2 SSM-1's in Y position "cross pairs". Example: an overall sound for drum kits, orchestras, choirs, etc.

The popularization of the "Zeppelin": 2 SSM-1's aligned on the ST2 forming the support for a "Shotgun" mic.
