Sound Devices 688 12-Input Field Mixer/Recorder


Sound Devices 688 contains six microphone preamplifiers that re-define portable audio performance. With its comprehensive inputs and extensive outputs, including direct outputs per channel, the 688 is at home in small run-and-gun applications as well as large, multiple-input productions. The 688 incorporates a complete feature-set into 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 four internal AA batteries or external 5–18 VDC."

The 688 is designed to withstand the physical and environmental extremes of field production. Its compact mechanic construction strikes the perfect balance between access to all functions, uncluttered design, and durability.
