Description
The Neumann KH 310 R is 3-way, 8”+3”+1", right active near-field reference monitor with analog controller with electronic-balanced input.
The KH 310 three-way active tri-amplified monitor features a Mathematically Modeled Dispersion™ Waveguide (MMD™), flexible acoustical controls, various input options 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 represents the latest in acoustic and electronic simulation and measurement technologies to ensure the most accurate sound reproduction possible.
The KH 310 is designed for use as a near-field monitor, as a front loudspeaker in mid-sized multi-channel systems, 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.
