The PS940 is a double-braced percussion stand for your Yamaha DTX-Multi 12. A Yamaha MAT-1 plate mount (sold separately) is required in order to attach the Multi12 to the PS940. The MAT-1 attaches to the stand's standard Yamaha hex-rod mount. The hex-rod is a six-sided steel rod connected to a resin ball joint mounted inside of a chrome housing. This ball joint allows for 360° rotation of the hex-rod, so it's easy to get your Multi 12 into the perfect position.
