Azden SMX-15 Powered Shotgun Video Microphone

The Azden SMX-15 Powered Shotgun Video Microphone was engineered to produce excellent sound quality for video recorded by DSLR and other compact cameras. The microphone element is the same used by Azden’s professional shotgun microphones, the SGM-250 an SGM-250P, and is capable of capturing broadcast quality sound. The acoustically tuned slots of the shotgun barrel give the SMX-15 its super-cardioid polar pattern which allows you to focus on sound in front of the camera, while reducing capture of extraneous noise from the rest of the environment.

DSLR cameras typically do not have much audio control. That's why Azden designed the SMX-15 with a +20dB gain booster; so you can get a strong, clean audio signal into your camera, minimizing the need to turn up the noisy preamp. Also included is a -10dB pad to protect against distortion when recording in loud environments such as live concerts and motorsport events.

The SMX-15 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. Integrated into the design of the SMX-15 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 ¼”-20 thread at the bottom for mounting to boom poles and other camera accessories.
