Crown PZM10

A low-profile, cost-effective PZM microphone featuring a 3/4" tubular housing for ceiling, wall or tabletop installations. Intelligibility is excellent, with low frequencies below the voice range rolled off to reduce the pickup of HVAC rumble. Applications include security, surveillance and conferencing.  XLR connector, phantom powered.
