As new, but box slightly tatty.
The Audio Technica AT851RX is a phantom powered plate mic, with built in Preamplifier. Designed for surface-mount applications requiring high-quality sound pickup.
Extended frequency response and uniform cardioid (120°) polar pattern.
Heavy die-cast case and rubber bottom pad minimize coupling of surface vibration to the microphone.
Low-profile design for minimum visibility, 25' (7.6 m) detachable cable with TA3F connector at mic, screw terminals at power module
