Microphone Boom Arm 32.3in Reach

The Avid MU-PSA28 is a desk-mounted microphone boom arm designed for streamers, podcasters and home-studio creators. It clamps to surfaces up to two inches thick and rotates 360 degrees at the base. The arm adjusts 135 degrees back and forth and 180 degrees up and down for silent, precise positioning.

Capacity and Headroom 3.5lb Load

Internal steel springs support microphones weighing up to 3.5 pounds, comfortably holding heavy models such as the Blue Yeti or Shure SM7B. The horizontal reach extends to 32.3 inches and the vertical height to 37.4 inches with the included 6.3-inch riser. Heavier broadcast microphones or added accessories beyond the rated load will exceed the spring capacity.

Standard Clamp 2in Desk Thickness

The fixed C-clamp design accepts desks up to two inches thick and does not offer a grommet-mount alternative. Buyers with thicker desktops, glass surfaces or permanent through-hole installations will need a different mounting solution.

Questions about this item

Will the 32.3 inch horizontal reach clear a large monitor while the clamp stays on a 2 inch thick desk?

The arm reaches 32.3 inches horizontally and the clamp fits desks up to 2 inches thick, so it can extend over most monitors while staying secured.

How can I confirm the arm moves smoothly and holds position after I mount a heavy microphone?

Adjust through the 135° horizontal and 180° vertical range plus 360° base rotation; the internal springs support up to 3.5 pounds so a heavy mic should stay exactly where you set it.

Does the box include the 3/8 to 5/8 adapter and the 6.3 inch extension riser, or must I buy them separately?

The package includes a 6.3 inch extension riser for extra height; the product description lists a 3/8 to 5/8 adapter in the compatibility table, so it is supplied with the arm.
