UNIQUE CONFIGURATION OF A LARGE COINCIDENT DIAPHRAGM CAPSULE
Unlike most X/Y stereo microphones where the capsules form a 90° stereo image, the BP4025 has ingenious arrangement of its large capsules for stereo more "realistic" 120° image. The two capsules are mounted back-to-back on the same electronic circuit.
This is a unique configuration of coincident large diaphragm capsules for impeccable sound quality and exceptionally low noise level. The audio reproduction - thanks to the excellent channel separation - is natural and powerful to give the listener the impression of being there when the audio was recorded.
