With the SMX-30V, Azden takes their innovation of a switchable stereo/mono microphone to another level by incorporating a mixing dial. The first video microphone of its kind, the SMX-30V lets the user choose from using 100% of the stereo microphone, 100% of the mono-shotgun microphone, or any mix in between. Recording a dialogue scene but want to incorporate some of the environment’s ambience? Mix in a little of the stereo microphone. Recording a musical performance but want to tighten up the center stereo image? Mix in some audio from the mono-shotgun microphone. The possibilities are endless!
The SMX-30V is like having a stereo microphone, a shotgun microphone and an audio mixer all combined into one unit. To achieve this, there are three microphone elements in total: two located at the top, angled at 90º for capturing a realistic stereo image, and one inside a 4.5-inch long interference tube for directional audio capture. Combined with a stepless mixing knob, you have complete control over how much signal from each microphone to send to your camera.
Another unique feature on the SMX-30V is the swiveling shock-mount, which enables rotation of the microphone 30º to the left or right. This is a handy feature any time your sound source is not centered in-frame, allowing you to aim the microphone at your subject, thereby getting the most direct sound possible. In addition, the mount itself is designed to absorb vibrations and isolate the microphone from handling noise. The bottom of the mount allows for attachment to a standard camera cold-shoe slot, or via a ¼”-20 threaded stud.
Battery life in the SMX-30V has been improved over the previous model to last up to 100 hours on a pair of alkaline AA batteries.

When engaged, the Low-Cut Filter (or High-Pass Filter) reduces low-frequencies which can be helpful in mitigating low-frequency noise from sources such as HVAC systems, wind or passing cars.
The 3 step gain control has +20 dB, 0 and -10 dB settings. Adding 20 dB of gain to the microphone output is a great way to overcome noisy mic preamps, or to simply boost quiet audio. Reducing the gain by 10 dB is most useful to protect against distortion in loud environments.
Setting to AUTO will turn the microphone on and off with your camera automatically, saving you from losing a great take and conserving battery.
