At the past AES in San Francisco Neumann presented the three-way monitor KH 310 A active monitors. The KH 310 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.
KH 310 A
The KH 310 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 represents the latest in acoustic and electronic simulation and measurement technologies to ensure the most accurate sound reproduction possible.
