Heil Sound RC 22 Dynamic Wireless Microphone Capsule

The RC 22 carries the PR 22 cardioid dynamic element on a standard wireless capsule thread, giving a wireless handheld the same 50 Hz to 18 kHz response and 145 dB of headroom as the wired version. For a house that already uses PR 22s on wired channels, it keeps the tonal match across the whole vocal system.

The thread is 31.3 mm at 1.0 mm pitch (1.25 in x 28), fitting most Shure, Sony, Lectrosonics, and Line 6 transmitters with removable capsules; some Sennheiser bodies work with the correct adapter. Output is -55 dB at 1 kHz into 600 ohms balanced, and the capsule weighs 4.9 oz. Chrome and gold finishes are stocked.
