This 512 AUDIO 512-BBA Microphone Boom Arm Kit from B&H contains four 512-BBA boom arms and adds four sets of Shure SRH840 closed-back, over-ear headphones, enabling two people to monitor their audio confidently and comfortably.
Equipped with a silent high-tension spring hidden from view and the ability to rotate 360°, the 512-BBA Microphone Boom Arm from 512 AUDIO offers sleek, quiet, and easy mic positioning for podcasters, content creators, novice broadcasters, and radio show hosts. Its two arms allow up to 31.5" of horizontal reach, plenty to put the mic right where you need it. The 512-BBA's steel construction provides stability while supporting a studio or broadcast mic weighing up to 3 lb (including a clip/mount).
Since the 512-BBA is compatible with 5/8"-27 and 3/8"-16 threads, it works with most mic clips and shockmounts. It attaches to a desk or table via an extrawide C-clamp that utilizes an antiscratch pad to prevent damaging the finish of your worksurface. For nonpermanent setups, the 512-BBA can be fully collapsed to ensure compact storage between sessions.
The Shure SRH840 are closed-back, over-ear professional monitoring headphones tuned to provide high-quality audio reproduction for critical listening during recording, editing, and mixing. Lightweight and sturdy, the headphones can also fold down for easy storage and transportation in the included carrying bag.
The SRH840 have large 40mm drivers that deliver a broad frequency response of 5 Hz to 25 kHz for rewarding bass, intelligible mids, and extended treble. The closed-back, circumaural design helps reduce ambient noise and the thick replaceable earpads yield long-lasting comfort. The wide headband is adjustable and generously cushioned to ensure a pleasing fit on a range of head sizes.
The coiled, single-sided cable allows a variable amount of slack, resists tangles, and can be detached for easy replacement. It has a bayonet clip to keep it securely attached to the earcup. The gold-plated 3.5mm TRS mini plug and 1/4" adapter enable compatibility with MP3 players and mobile devices as well as DJ mixers and audio interfaces.
