Shure AD2/K9HSN
The AD2/K9HSN is a handheld wireless transmitter for Shure Axient Digital systems carrying the KSM9HS dual-diaphragm condenser cartridge, finished here in nickel. The KSM9HS gives a vocal the open, detailed top end of a studio condenser, and its switchable hypercardioid and subcardioid patterns let an engineer trade tighter rejection for a more forgiving pickup depending on the room and the singer. Axient Digital delivers it with wide tuning up to 184 MHz, selectable modulation modes, and encrypted transmission for a reliable channel in crowded spectrum.
Selectable RF output of 2, 10, or 35 mW balances range against channel count, and Standard and High Density transmission modes let you scale the number of simultaneous systems. It ships in G57 (470-616 MHz), K54 (606-663 MHz), or X55 (941-960 MHz) tuning bands with a microphone clip, zipper bag, two AA batteries, and a user guide.
