KH 120 II
Studio Monitor
From Neumann:
The KH 120 II is based on the same concept as its acclaimed predecessor but completely re-engineered for improved performance in all parameters: deeper bass, higher SPL capability and even better resolution. Internal DSP power allows for phase linear crossovers and room adaptive alignment via Neumann’s revolutionary MA 1 Automatic Alignment.
When Neumann released the KH 120 A in 2010, it was the beginning of an ongoing success story. Neumann monitoring has since become the reference of choice in countless studios around the world. The KH 120 II follows the same philosophy as its predecessor and, in fact, all Neumann studio monitors: highest linearity, lowest distortion, no coloration, and perfect adaptability to any acoustic environment. Thanks to improved performance in all parameters and a powerful DSP engine, the KH 120 II enables you to hear your tracks with even greater clarity and work more efficiently. Create mixes that translate optimally to all playback systems. With ease.
The KH 120 II has an exceptionally linear frequency response from 44 Hz to 21 kHz (±3 dB). Not only that: It also linearizes the phase response! Which translates to clear mids with astonishing transparency as well as extreme accuracy in the time domain: precise impulse reproduction and finely resolved reverbs. This is made possible by DSP controlled electronics which allow for sophisticated crossovers avoiding the phase distortion caused by analog filters. The internal DSP also realizes new standards in tonal consistency. The KH 120 II is made to extremely low tolerances of no more than ±0.5 dB! And you can hear it, too: Stereo imaging is razor-sharp.
