Neumann KH 120 A - Active Studio Monitor Speakers PAIR


The Neumann KH 120 A is an incredibly detailed and accurate 5 inch powered monitor.  Perfect for tracking, mixing and mastering in music, broadcast, project and post-production studios. The 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 Modelled 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.


    • NEUMANN KH120 PRODUCT FEATURES:

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

      Elliptical Mathematically Modelled Dispersion™

      (MMD™) waveguide - Smoother off-axis response, More forgiving of diverse acoustical environments

      Composite sandwich cone - Damping of break-up modes

      Long throw bass driver - Low distortions at high sound levels

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

      Robust metal grille - Protects against mechanical damage

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

      Compact aluminum cabinet

      (magnetically shielded) - Minimizes resonances, better heat dissipation, long life

      Wide horizontal dispersion - Freedom of movement across the mixing console

      Narrow vertical dispersion - Reduces reflections off the mixing console

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

      Powerful analog amplifiers with large headroom - Improved transient response

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

      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

      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

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

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