Model Description:
The Ultimate Portable Mixer for Production, ENG, and Film

Model Details

Developed with input from the industry's top audio engineers, Sound Devices 442 encompasses the audio performance, feature set, and mechanical construction demanded by those who rely on audio gear for their livelihood. The 442 contains four microphone preamplifiers that re-define portable audio performance. With its comprehensive inputs and extensive outputs, including direct outputs per channel, the 442 is at home in small run-and-gun applications as well as large, multiple-input productions.

The 442 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 442 and 442N, like all Sound Devices professional audio products, are 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.
