Neumann KH 120D Active Studio Monitor with Digital Input and Delay

Neumann KH 120D
Product Code: KH120D

The KH 120 D studio monitor is designed for use as a near-field loudspeaker or as a rear loudspeaker in larger multi-channel systems. The KH 120 D 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, various input formats (analog and digital) 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 D is perfect for tracking, mixing and mastering in music, broadcast, project and post-production studios.

Features	Benefits
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
XLR analog input / 24 bit, 192 kHz, AES3 and S/P-DIF	Compatible with commonly used digital signals
BNC input and buffered BNC output	For flexible and trouble-free digital interconnectivity
Lipsync delay (0 … 10/12 frames)	To align audio and video signals
Time-of-flight delay (0 … 400 ms)	To compensate for listening distance differences
