K&M Stands 21120 Boom Arm (Black)

Extended Boom Arm for Wide-Reach Microphone Positioning
The K&M 21120.577.55 is an extra-long, two-piece telescopic boom arm built to handle demanding mic placement needs on stage, in the studio, or during live broadcasts. With a generous extension range from 17" to 37", this boom arm is ideal for positioning microphones over drum kits, large ensembles, or elevated sound sources without repositioning your mic stand.

Ideal for Musicians, Engineers, and Broadcasters
Whether you're capturing vocals, instruments, overheads, or ambiance, this boom arm adapts to a variety of audio environments. Its extended reach makes it especially useful in complex stage setups or large studio spaces where precise mic placement is essential for optimal sound capture.

Smooth Telescoping Design for On-the-Fly Adjustments
The two-piece design allows users to quickly adjust the boom length to match each scenario. This level of control makes it easier to keep microphones out of frame in video shoots or clear of musicians during live performances, while still maintaining perfect mic placement.

Secure Locking System Prevents Slippage and Drift
A simple yet effective wing nut-style locking mechanism ensures that the arm stays firmly in place once adjusted. Even when supporting heavier microphones, the locking system maintains balance and prevents mic sagging, offering peace of mind during long sessions or high-pressure performances.

Silent Swivel Joint for Precise Microphone Angling
Equipped with a smooth-action swivel joint, the 21120.577.55 offers silent angle adjustments that won’t interfere with recording or live sound. This feature is particularly important for controlled studio environments, where mechanical noise and mic handling artifacts need to be eliminated.

Standard Compatibility With Professional Mic Stands
The boom arm connects to any standard microphone stand using a 5/8" threaded connector, ensuring compatibility with a wide range of clips, holders, and shock mounts. It’s a seamless upgrade to existing hardware and fits effortlessly into any professional audio workflow.

Durable Construction With a Matte Black Finish
Made from rugged steel and finished in matte black, the 21120.577.55 is both visually unobtrusive and built to withstand regular use. Its robust construction supports years of reliable service, even in busy production settings, making it a staple tool for touring musicians, rental houses, and production crews.
