The Azden SMX-30 was engineered to be the ultimate video microphone with outstanding audio quality, appealing design, ergonomic form factor, and all of the functional features one expects in a top-of-the-line, camera-mounted microphone.
Housed inside an innovative casing, the SMX-30 is actually two microphones packaged into one. The stereo microphone is positioned at the top and consists of 2 cardioid polar pattern microphone elements spaced apart at a 120§ angle for capturing a natural sounding stereo image. The mono microphone uses a super-cardioid polar pattern to focus on sound in front of the camera and is equipped with the same high-quality element as Azden's SGM-250 shotgun microphone to record broadcast quality sound.
With a +20dB gain booster; you can get a strong, clean audio signal into your camera, minimizing the need to turn up the camera's noisy preamp. Also included is a -10dB pad to protect against distortion when recording in loud environments such as live concerts and motor sport events. The SMX-30 has a wide frequency response ranging from 40Hz to 20kHz, so the audio you capture will sound full and natural. Additionally, a low-cut filter switch is included for reducing the level of low frequencies below 120Hz, which is especially useful for mitigating noise caused by air conditioners, wind and traffic.
The SMX-30 is powered by two AA batteries for up to 24 hours of operation. The battery indicator LED light lets you know when it's time to change batteries with up to a 1 hour warning. Maximize battery life by using the unique "Auto" power setting. When set to Auto, the SMX-30 can detect when a camera is on and will automatically power on and off with the camera (requires a mic input that provides plug-in power). Integrated into the design of the SMX-30 is a custom made, shock absorbing shoe mount to isolate the microphone from camera motor and handling noise. The mount is designed to fit the standard camera shoe and comes with a ¬"-20 thread at the bottom for mounting to boom poles and other camera accessories.
