The R DE VideoMic Pro R is a true shotgun microphone designed for use with camcorders, DSLR cameras and portable audio recorders as a source of primary and reference audio. At the heart of the VideoMic Pro R is a 1/2" condenser capsule that provides broadcast-quality audio via a 3.5 mm minijack connector (outputting the mono signal to both left and right channels) with an incredibly low self-noise of just 14 db. A super-cardioid polar pattern ensures that surrounding audio is minimized, and your recording is focused on the subject in front of the camera. The integrated Rycote Lyre based shock mounting system separates the VideoMic Pro capsule and electronics from its mount, providing isolation from external physical factors that may cause unwanted rumble and vibrations in the microphone. Constructed from a single piece of hard-wearing thermoplastic, the Lyre provides superior acoustic suspension to traditional elastic solutions, and will never wear out, sag or snap. Easily accessible on the rear face of the microphone are the power, filter and level controls. In addition to the microphone's native 40 Hz - 20 kHz response a selectable high-pass filter at 80 Hz is available, which will prevent low end noise such as air conditioners and traffic from being recorded. Below these controls are the level settings, which attenuate or boost the recorded level as required. The -10 dB level attenuation (or PAD) is ideal for recording loud sound sources, such as live music, motorsport, or interviews where the subject is very close to the camera. The +20 dB level boost is designed for use with DSLR cameras, allowing the user to reduce the camera's preamp level (or mic-input level), effectively reducing the amount of noise generated by the camera's comparatively low quality audio circuitry. The microphone uses a standard sized shoe mount for on camera use, and features a 3/8" thread in the base of the mount for easy boom pole mounting. The VideoMic pro is battery powered.
