Product Description

Flexible mixing for the field!

The Sound Devices 302 portable field mixers are great for the pro on the go! Developed for audio-for-picture applications, the 302 mixer is the perfect tool for production companies and camera operators wanting to take control of their audio. The 302 is stunning for its size, flexibility, control, and performance. It is the most compact and cost-effective battery-powered professional audio mixer in its class. For pros and hobbyists alike, the Sound Devices 302 is great for on-the-go audio for video production.


With important features to accommodate nearly any over-the-shoulder production, the 302 interfaces with wireless transmitters and receivers, camera audio inputs of all kinds, and external audio recorders. Its microphone inputs share the same superb circuitry of all Sound Devices field production tools.

Compact and powerful

Like Sound Devices larger 442 Field Mixer, the 302 has a complete feature-set in a compact, functional design. All controls are accessible on its three main surfaces, so there are no hidden controls. The high-efficiency power circuitry runs the mixer from either three internal AA batteries or external 5-18 VDC.

Studio-style features in a portable box

The 302 is loaded with features that put it on par with gear commonly found in professional studios. Three transformer-balanced mic/line level inputs provide great, clean sound. Limiters on the inputs and outputs prevent overs. Plus, the addition of MS linking of channels 1 and 2 provides a great method for stereo recording.
