The Ultimate Portable Mixer for Production, ENG, and Film
The 442N is identical in every way to the 442 mixer, with the exception of its metering scale. The 442N references a Nordic scale PPM meter for compatibility with Nordic scale gain structures. This meter scale shows additional resolution between -10 dBu and +4 dBu.
The 442N 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.
