Rode PSA 1 Swivel Mount Studio Microphone Boom Arm.
From the manufacturer
Whether you’re podcasting, broadcasting, on the radio, or streaming at home, microphone placement is everything. The PSA1 is a professional studio boom arm that will help you position your microphone exactly where it needs to be.
With its parallelogram spring design for keeping the microphone perfectly stable even when the arm height is adjusted, the PSA1 will help you get the perfect recording every time.
Unlike many other studio arms, the PSA1 features internal springs for quiet operation, meaning that even large movements won’t result in mechanical noise ruining your recording.
The PSA1 comes with everything you need in the box, including a threaded desk insert for mounting in a studio setup, as well as a clamp for quick and easy mounting onto a desk.
