Neumann KH 310 A (Left)

EXPANDED MIDRANGE PRECISION " DRY BASS SOUND With its specially designed midrange driver, the compact KH 310 is particularly suited for precise work with speech, vocals, guitars and other instruments that have a midrange emphasis. Its closed design enables a very fast transient response. The associated low harmonic distortion guarantees a neutral reference sound to meet the highest standards.

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.

It can be used in project, music, broadcast centers, OB vans, and post production studios for tracking, mixing, and mastering.
