Making good quality films has always been a challenge for low budget independent video makers. In the absence of specialized video making equipment, amateurs have to sacrifice the quality of the film. Mitra 3D Mic Indie is a low budget solution for these independent low budget movie producers. The 3D Mic Indie records the sound in such a manner that when played, it recreates the original three-dimensional sound effect.
Mitra has incorporated the 3D Mic Indie with their patent pending SHEM (Simplified Human Ear Model) technology. The ear responds better to certain frequencies as compared to others. Using this technique, the device records the sound similar to the way a human ear perceives it. The result is a sound that makes the user feel like being part of the action, giving a 3D experience. The output device may be a couple of speakers, headphones or ear-buds.
The 3D Mic Pro can be connected to any audio/video recording device, DSLR or video camera via the two XLR sockets provided. The electronics of the device have been designed to produce a signal that is less susceptible to loses. This allows the use of long cables without having to worry about signal interference or buzzing in sound.
The device is light and portable. Two 9 volt alkaline batteries serve as the power source, which can run the device for up to 12 hours. There is no need for any power cable. Two battery power level lights are provided to indicate the health of the batteries.
For added versatility, the 3D Mic Indie can be mounted to boom poles and speaker stands. Windscreens are also available to prevent interference of wind noise with the recording.
