The SMX-30 Stereo/Mono Switchable Video Microphone from Azden is a battery-powered microphone with separate stereo and shotgun-style microphone units that can be switched between mono and stereo recording modes. It can be used to produce pro-quality sound for DSLRs and other compact cameras in applications for interviews, weddings, presentations, and more.





Housed inside an innovative casing, the SMX-30 is two microphones packaged into one. The stereo microphone is positioned at the top and consists of two cardioid polar patterns spaced apart at a 120° angle. The mono microphone uses a supercardioid polar pattern to focus on sound in front of the camera. It has the same high-quality element as Azden's SGM-250 shotgun microphone.





Using the built-in 20 dB gain booster to get a strong clean audio signal into your camera, the SMX-30 minimizes the need to turn up noisy preamps usually associated with DSLRs, and also includes a -10 dB pad to protect against distortion when recording in loud environments such as live concerts and motorsport events.





Furthermore, the microphone has a wide frequency response of 40 Hz to 20 kHz and has a full, natural sound. There is a low-cut filter switch for reducing low frequencies below 120 Hz, which is useful for mitigating noise caused by air conditioners, wind, and traffic.





Powered by two AA batteries, you can operate the SMX-30 microphone for approximately 24 hours with no degradation of sound quality. The battery-indicator LED light lets you know when it's time to change batteries with up to a 1-hour warning beforehand.





Finally, an integrated shock-absorbing shoe mount isolates the SMX-30 microphone from camera-motor/handling noise. The mount is designed to fit the standard camera shoe and comes with 1/4"-20 threads at the bottom for mounting to boom poles and other camera accessories. A foam windscreen and a carry pouch are also included.The SWS-30 Furry Windshield Cover from Azden was designed specifically for the SMX-30 microphone to provide maximum protection against wind noise in outdoor environments. The cover is made to slip over the SMX-30's included, custom-fit foam windscreen and delivers acoustically transparent results.
