The KH 120 is a studio monitor 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), 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.

Neumann KH 120 A Studio Monitor Features

Compact aluminum cabinet (magnetically shielded) - minimizes resonances, better heat dissipation, long life

Non-parallel cabinet walls - Greatly attenuated internal standing waves

One-piece front panel with no discontinuities - Reduced diffraction and smoother frequency response

Powerful titanium fabric dome - Low-distortion high-frequency reproduction

Elliptical Mathematically Modeled Dispersion (MMD) waveguide - More forgiving of diverse acoustical environments

Wide horizontal dispersion - Freedom of movement across the mixing console

Narrow vertical dispersion - Reduces reflections off the mixing console

Two-colour + dimmable Neumann logo - Displays operation status and activation of the extensive protection system

Robust metal grille - Protects against mechanical damage

Long throw bass driver - Low distortion at high sound levels

Large front panel ports - Reduced bass compression and easier to mount in tight spaces such as OB vans

A subwoofer, such as the Neumann KH 180, with its 7.1 High Definition Bass Manager, can be added to deepen the low-frequency response to 18 HZ and increase the system's maximum output level

4-position bass, low-mid and treble acoustical controls - More control in diverse acoustical environments

Wide range input gain and output level controls - Easier interfacing with signal sources

New mounting hardware options - More flexibility in mounting cabinets in more diverse locations

Separate woofer and tweeter electronic peak limiters and thermal-protection circuitry - High reliability

Powerful analog amplifiers with large headroom - Improved transient response

Production consistency - Any KH 120 is "pair-matched" to any other KH 120

Universal switched-mode power supply (100...240 V) - One version works in any country and robust to poor quality mains supply

Display dimmer - For low lighting level conditions or behind the screen applications

Ground lift - Reduced noise in electrically noisy environments and over-comes ground loops
