Azden SMX-30 Stereo/Mono Switchable Video Mic

$249.00

The 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.

If you only have the budget to buy one microphone for your camera, why should you have to choose between mono or stereo? The SMX-30 is stereo/mono switchable, so you don’t have to.

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 120º 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.

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-30 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.

About the Azden SMX-30 Stereo/Mono Switchable Video Mic

The Azden SMX-30 is a versatile, professional on-camera shotgun microphone designed for videographers and filmmakers seeking high-quality audio capture directly into their cameras. Its defining feature is a switchable stereo/mono operation, allowing the user to choose between a focused, directional mono signal ideal for dialogue and interviews, or a wider stereo field for capturing ambient soundscapes, music, and environmental atmosphere. This flexibility makes it a valuable all-in-one microphone for a wide range of video production scenarios, from documentary work and event coverage to indie filmmaking. The microphone is engineered with a dual-capsule design to facilitate true stereo recording, providing a realistic sense of space and depth when in stereo mode, while the mono mode delivers the clean, forward-rejecting performance expected from a short shotgun microphone.

The SMX-30 is built for practicality in the field. It features a low-profile design that mounts securely on a camera's hot shoe or via a standard microphone clip, and it includes a built-in shockmount to isolate the microphone from handling noise and camera-operational vibrations. Power is conveniently supplied via a single AA battery or through plug-in power (3-5V) from compatible cameras, ensuring compatibility with a wide range of DSLR, mirrorless, and camcorder models. The microphone offers user-adjustable sensitivity (level) control and a low-cut filter switch to reduce wind rumble and low-frequency room noise. Output is through a standard 3.5mm TRS mini-jack, making it directly compatible with the microphone input on most consumer and prosumer video cameras.

Housed in a durable, lightweight metal body, the Azden SMX-30 is a robust and reliable tool that significantly upgrades the audio recording capability of any camera system. By combining stereo and mono functionality with essential built-in features, it provides content creators with a professional, straightforward solution for capturing superior sound without the need for complex external recorders or mixers.
