d:mension 5100 Mobile 5.1 Surround Mic
It brings engaging surround ambience to sport events, documentaries and other HDTV productions. The mic requires no external signal processing.
This microphone is versatile. You can mount it in many ways: on a camera, microphone stand, suspended from the ceiling or via a hand grip. It is lightweight and portable. It can also withstand inclement weather conditions due to its robust nature.
The d:mension? 5100 Mobile Surround Microphone is a completely self-contained plug-and-play solution for 5.1 audio capture. It uses five miniature pressure transducers. These transducers have low sensitivity to wind and mechanical noise, low distortion and low frequency response. They also have a large dynamic range. Appropriate channel separation and directionality is achieved by combining the use of DPA Microphones' proprietary Directional Pressure Microphone (DiPMic?) technology with the use of acoustic baffles. DiPMic? mounts interference tubes on the L/C/R omnidirectional capsules. Acoustic baffles preserve the accuracy of levels between the discrete analog output channels.
The three front microphones in this system are time aligned to eliminate comb filtering. This also ensures frequency consistency when down mixing to stereo or mono. In contrast, the rear microphones, with standard omnidirectional patterns, are optimally spaced from both each other and the front array to simulate the most natural time arrival differences. The LFE (0.1) channel is comprised of a L/R sum, which is then attenuated 10 dB in comparison with the signal from the main channels. This is in accordance with the 5.1 format.
The d:mension? 5100 Mobile Surround Microphone provides a surround atmosphere that is rich, smooth and enveloping. It is great in its coherence, channel separation and localization accuracy.
The 5.1 output of the microphone runs through a multipin Lemo connector. This connector carries all six electronically-balanced channels. The microphone comes with a five-meter (16 ft), six-pair Mogami that cable breaks out to six Neutrik XLR-M connectors.
