Description

Small, Powerful Audio Mixer for ENG

Developed specifically 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.

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.

Like Sound Devices larger 552 Field Mixer, the 302 has a complete feature-set in a compact, functional design. All controls are accessible on its three main surfaces; no hidden controls. The high-efficiency power circuitry runs the mixer from either three internal AA batteries or external 5-18 VDC.
