I'm selling this because I bought it but barely used it. This is a microphone recommended by a professional photographer. It's clean and there is no corrosion in the battery compartment. This item includes the microphone body and batteries only. Thank you. Details from the HP: * Type: Condenser * Polar Pattern: Supercardioid * Frequency Response: 40Hz~20,000Hz (Variable High-Pass Filter @ 80Hz) * Sensitivity: -38dB ±2dB re 1V/Pa @ 1kHz * Output Impedance: 200Ω * Equivalent Noise: 20dBA SPL (IEC651) * Maximum Output: +6.9dBu (@ 1% THD; 1kΩ) Product Description The VideoMic Rycote is a professional-grade 1/2-inch condenser shotgun microphone designed for use with consumer video cameras and personal audio recorders. The integrated Rycote Lyre-based shock mount system isolates the VideoMic capsule and electronics from its all-metal shoe mount, eliminating external physical factors that may cause unwanted rumble and vibrations in the microphone. Constructed from a single piece of durable thermoplastic, it will almost never sag, break or wear out. The Lyre also provides superior acoustic suspension compared to traditional elastic solutions. The standard-sized shoe mount base has a 3/8-inch thread for easy mounting on boom poles and stands. With its supercardioid polar pattern, the VideoMic is highly directional, focusing on the sound source in front of the camera while minimizing any surrounding sounds. In addition to the microphone's native 40Hz-20kHz response, a high-pass filter can be set to 80Hz to prevent low-frequency sounds such as air conditioning and traffic noise from being recorded. A selectable 10dB and 20dB level attenuation function (or PAD) from inside the battery compartment allows you to record loud sound sources such as live music and motorsports competitions.
