Neumann is excited to introduce its latest innovation, the KH 120, representing the first product in the new line of Neumann Studio Monitors. 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 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.FeaturesProduct Feature Benefit to the Customer Powerful titanium fabric domeLow-distortion high-frequency reproduction Elliptical Mathematically Modelled Dispersion™ (MMD™) waveguideSmoother off-axis response,More forgiving of diverse acoustical environments Composite sandwich coneDamping of break-up modes Long throw bass driverLow distortions at high sound levels Two-color + dimmable Neumann logoDisplays operation status and activation of the extensive protection system Robust metal grilleProtects against mechanical damage Large front panel portsReduced 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 dispersionFreedom 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 headroomImproved transient response Production consistencyAny KH 120 is “pair-matched” to any other KH 120 4-position bass, low-mid and treble acoustical controlsMore control in diverse acoustical environments Wide range input gain and output level controlsEasier interfacing with signal sources New mounting hardware optionsMore flexibility in mounting cabinets in more diverse locations Display dimmerFor low lighting level conditions or behind the screen applications Ground liftReduced 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 circuitryHigh reliabilityTechnical DataAcoustics -3 dB free field frequency response 52 Hz … 21 kHz, ± 3 dBPass band free field frequency response 54 Hz … 20 kHz, ± 2 dBSelf-generated noise (with input gain set to 100 dB for 0 dBu) Sine wave output with a THD Max.
