The Neumann KH 120 A studio monitor is designed for use as a near-field loudspeaker or as a rear loudspeaker in larger multi-channel systems. The KH 120 A represents the latest in acoustic and electronic simulation and measurement technologies to ensure the most accurate sound reproduction possible. It has a Mathematically Modeled Dispersion waveguide (MMD (TM), flexible acoustical controls, analog class-AB amplifiers, a large headroom analog input and an extensive mounting hardware range. All of this provides the user with the maximum versatility over a wide variety of acoustic conditions, source equipment, and physical locations.
The KH 120 is perfect for tracking, mixing and mastering in music, broadcast, project and post-production studios.
