Share

NOTE: Price shown is for a single unit.

The Neumann KH 310 A is designed for use as a near-field monitor, as a front loudspeaker in mid-sized multi-channel system, or as a rear loudspeaker in a larger multi-channel system. It can be used in project, music, broadcast centers, OB vans, and post production studios for tracking, mixing, and mastering.

The KH 310 A three-way analog active studio monitor features a Mathematically Modeled Dispersion™ Waveguide (MMD), flexible acoustical controls, various input options, analog class-AB amplifiers, and an extensive range of mounting hardware. This allows the loudspeaker to be used in diverse acoustical conditions, with any source equipment and in a wide variety of physical locations. The KH 310 A represents the latest in acoustic and electronic simulation and measurement technologies to ensure the most accurate sound reproduction possible.

Indcluded in the package is the KH 310 A, 3 main cables, 4 self-adhesive feet, and operating manual. Please specify left or right monitor when ordering.
