Product Feature

Benefit to the Customer

Low-distortion high-frequency reproduction

Smoother off-axis response,
More forgiving of diverse acoustical environments

Damping of break-up modes

Low distortions at high sound levels

Displays operation status  and activation of the extensive protection system

Protects against mechanical damage

Reduced bass compression and easier to mount in tight spaces such as OB vans

Minimizes resonances, better heat dissipation, long life

Freedom of movement across the mixing console

Reduces reflections off the mixing console

Reduced diffraction and smoother frequency response

Improved transient response

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

More control in diverse acoustical environments

Easier interfacing with signal sources

More flexibility in mounting cabinets in more diverse locations

For low lighting level conditions or behind the screen applications

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

One version works in any country and robust to poor quality mains supply

High reliability

Compatible with any analog line signal

For flexible and trouble-free digital interconnectivity
(24 bit, 192 kHz, AES3 and S/P-DIF)

To align audio and video signals

To compensate for listening distance differences
