International orders*The Holophone PortaMic 5.1 Surround Microphone provides prosumer video camera users with a simple, yet professional means of capturing audio in true 5.1 surround sound. The PortaMic 5.1 operates on a 9V battery and features an elliptical shape that mimics the acoustic properties of human hearing.
Six individual microphone capsules effectively capture left-front, right-front, center, left-rear, right-rear, and sub channels. A built-in Dolby ProLogic II encoder automatically encodes discrete audio for stereo output using the included cables. Audio can be decoded back to discrete 5.1 channels in post-production using Holophone D-Code or any Dolby ProLogic II decoder.
A 12dB pad switch maximizes headroom and minimizes noise and peak distortion when capturing transient-rich and excessively loud audio signals. The microphone is built for quick, plug-and-play operation and its built-in camera shoe and low-profile design provide exactly the right combination of familiarity and ease of use expected by professional and consumer camera operators alike.
