KH 120 A G – Active Studio Monitor

KH 120 A G – Active Studio Monitor

Product Feature Benefit to the Customer
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
