Description
The BP4025 is a fixed-charge condenser microphone with an X/Y stereo polar pattern. It is designed for professional broadcast and recording, and field use. The microphone requires 11V to 52V phantom power for operation.
The microphone offers large-diaphragm capsules in an innovative coincident capsule configuration. This allows for a smaller housing while producing an X/Y stereo image with the spatial impact and realism of a live sound field.
The microphone includes a 5 m (16.5') output cable terminating in a 5-pin XLRF-type and two 3-pin XLRM-type connectors. The output of the microphone is a 5-pin XLRM-type connector. The microphone is equipped with a switchable 10 dB pad and a switch that permits choice of flat response or low-frequency roll-off (via integral 80 Hz high-pass filter).
The microphone is enclosed in a rugged housing. The included AT8405a stand clamp permits mounting on any microphone stand with 5/8"-27 threads. A windscreen and a soft protective pouch are also included.
