Heavy-Duty Boom Arm for 2 kg Microphones

The Avid BM63 is a scissor-style microphone boom arm built from sturdy metal with a reinforced design that supports microphones weighing up to 2 kg. It attaches to a desk using a C-clamp with a protective pad and includes a standard 5/8-inch mounting screw. The arm suits podcasters, streamers and gamers who need a stable, adjustable microphone position without drilling permanent holes in furniture.

Upgrade from Lightweight or Fixed Stands

A basic straight stand or entry-level arm often flexes under heavier broadcast microphones and transmits desk vibrations into recordings. The BM63 replaces those solutions when the microphone exceeds their load rating or when boom noise becomes audible during intense sessions. Its 2 kg capacity and rigid scissor joints keep the mic steady even if the desk is bumped during gaming.

Sustained Position Holding and Noise Isolation

Under continuous use the arm holds its set angle through friction joints that allow 180 degrees of vertical reach and 135 degrees of horizontal sweep, plus full 360-degree base rotation. The suspension design keeps the microphone suspended away from the desk surface, reducing low-frequency vibration transfer during long recording or streaming sessions. Velcro cable ties route the cable along the arm to prevent snagging when the boom is repositioned.

Questions about this item

How thick a desk can the C-clamp with protective pad grip?

The C-clamp is designed for standard desk thicknesses; the protective pad prevents surface damage while the clamp secures the 900 gram arm.

Which joint angle do users most often set incorrectly when first assembling the scissor arm?

The horizontal joint allows 135° of travel; users frequently leave it short of the full range, limiting the 42 cm reach.

When should the velcro cable ties be replaced to keep cables managed on the boom arm?

Replace the velcro ties when the hook-and-loop grip no longer holds cables firmly against the 14.33 in wide arm tube.
