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 as the 552 Portable Production Mixer and MixPre-D Compact Field Mixer.
Like Sound Devices larger 552 Field Mixer, the 302 is a complete Field Mixer, but designed in a super-compact package. Controls are accessible on its three main surfaces, its high-efficiency power circuitry runs the mixer from either three internal AA batteries or external 5-18 VDC.
