Audio-Technica BP4025 X/Y Stereo Field Recording Microphone

The BP4025 packs two large-diaphragm condenser capsules into a coincident X/Y configuration, so a single compact mic delivers the spatial impact of a full stereo field without the bulk of a spaced-pair setup. That coincident geometry means the two channels stay phase-coherent, which matters for anyone who needs their stereo recording to fold down cleanly to mono for broadcast.

It handles up to 145 dB SPL before clipping (155 dB with the 10 dB pad engaged), giving it enough headroom for anything from a quiet room tone to a loud outdoor event, and its 80 Hz low-frequency roll-off cuts wind and handling rumble before it reaches tape. It ships ready to record: a 5 m stereo cable terminating in two 3-pin XLRM connectors, an AT8405a stand clamp, windscreen, and a soft protective pouch are all included.
