Audio-Technica AT8545 Power Module, cH-Style to XLR In-line microphone power module

The AT8545 is the power module for Audio-Technica's cH-style microphones: the BP892x, BP893x and BP894x headworn ranges and any A-T lavalier or headset terminated with the screw-down 4-pin cH connector. It accepts that connector on the input and gives you a 3-pin XLRM output.

Use it to run a mic that was specified for a cH bodypack straight into a wired input, which is the usual fix when a room turns out to have no clean RF or when a lectern channel is permanent. It ships with a snap-on belt clip.
