DPA introduces surround microphone

DPA is set to introduce its 5100 mobile surround microphone — first shown at the IBC show in September last year and slated for delivery soon.

The 5100 is lightweight, portable and highly resilient to inclement weather conditions. It can be mounted on a camera or microphone stand, suspended or handheld, and requires no additional signal processing.

It employs five miniature pressure transducers that exhibit low sensitivity to wind and mechanical noise, low distortion, consistent low frequency response and wide dynamic range.

DPA said optimum channel separation and directionality are achieved through a combination of the company’s DiPMic (Directional Pressure Microphone) technology, which mounts interference tubes on the L/C/R capsules, and the use of acoustic baffles that preserves the accuracy of levels between the discrete analog output channels.

The 5100’s three front microphones are time coincident to eliminate comb filtering and to ensure frequency consistency when downmixing to stereo or mono. In contrast, the rear microphones, which feature standard omnidirectional patterns, are optimally spaced from both each other and the front array to simulate natural time arrival differences.
