The audio controls on DSLR cameras are limited, if they exist at all. And DSLRs are notoriously known to have low-quality microphone preamps that add noise to the video soundtrack when the gain is turned up. 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.
The SMX-15 is powered by two AA batteries; a lower cost option than the 9V battery that is used in some competitor microphones. The SMX-15 can achieve 24 hours of operation with a single set of batteries with absolutely 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.
Maximize battery life by using the unique “Auto” power setting. When set to Auto, the SMX-15 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). Ever leave your microphone on by accident to discover that the batteries are dead the next time you try to use it? Eliminate that possibility by always leaving the SMX-15 in “Auto” mode.
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.
