Neumann KH 150 AES67 2-Way DSP Nearfield Monitor, Black

NEUMANN ACCURACY, SERIOUS BASS AND POWER TO SPARE
The KH 150 is a powerful bi-amplified studio monitor with reference-class performance. Its 6.5” woofer in a bass reflex cabinet provides stunning low end and high SPL capability with undiminished clarity. DSP controlled electronics ensure linear phase response and allow for room-adaptive calibration via Neumann’s revolutionary MA 1 Automatic Monitor Alignment.

WHAT YOU HEAR IS WHAT YOU GET
The KH 150 follows the same philosophy as all Neumann studio monitors: highest linearity, lowest distortion, no coloration, and perfect adaptability to any acoustic environment. It allows you to hear every nuance of your tracks. Mixing becomes so much faster and easier, once the guesswork is over. And more creative, too: Sounds genius, but can I get away with that? Is that vocal bright or sibilant? Is it too much bass? The KH 150 will tell you. Honestly.

ONE BIGGER
What differentiates the KH 150 from its smaller siblings is its deeper bass response down to 39 Hz. That’s almost as low as the larger KH 310, thanks to the KH 150’s novel 6.5” high-precision woofer in a carefully designed bass reflex cabinet. The KH 150 is thus ideally suited to urban music, EDM, film scoring, and all styles that require extended low end and/or elevated listening levels. Thanks to powerful amplifiers (145 W/100 W) and sophisticated protection limiters, no clarity is lost even at high SPLs. But, being a true universalist, the KH 150 works just as well for everything from rock to classical music, broadcast applications and voice-over work.

The KH 150 has an exceptionally linear frequency response from 39 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 150 is made to extremely low tolerances of no more than ± 0.8 dB! And you can hear it, too: Stereo imaging is razor-sharp.

READY FOR YOUR ROOM
Even the best loudspeaker only sounds as good as the acoustic environment allows. Neumann’s Mathematically Modelled Dispersion (MMD) waveguide guarantees a wide sweet spot and minimizes desk reflections. But the KH 150 goes much further: Its internal DSP allows for room calibration via Neumann’s revolutionary Automatic Monitor Alignment. MA 1 (sold separately) makes sure your DSP powered monitors are optimally adapted to the character of your room and perfectly calibrated for your listening position. Even in acoustically treated rooms, this results in a huge improvement.

Tonal compatibility with other KH line studio monitors makes it possible to use the KH 150 in mixed setups e.g., in surround/immersive setups. For flexible connectivity the KH 150 features both analog and digital inputs.

AES67 - AUDIO OVER IP
Additionally, the KH 150 AES67 model variant offers integrated redundant AES67 audio network ports that are fully compliant with broadcast standards such as ST 2110, ST 2022-7 redundancy, and RAVENNA. At the same time, the KH 150 AES67 is compatible with DANTE-generated AES67 network streams.

ENERGY EFFICIENT
Neumann engineers took great care to develop a patent pending amplifier technology which combines superior audio performance with the energy efficiency of Class D. Although the KH 150’s amplifiers deliver up to 145 W to the 6.5” woofer and 100 W to the 1” tweeter, they only consume 17 W at idle. Auto-standby reduces power consumption to 0.3 W when the KH 150 has not been used for a while, but can be deactivated.

MOUNTING OPTIONS
Most of the KH 120 accessories also fit the KH 150, with the exception of the LH 65 table stand, which is available in a slightly larger version in the form of the new LH 66 (Cat. No. 700258). The LH 61 (L bracket) was updated, because the KH 150 is a bit heavier/larger than the KH 120 and the LH 64 (VESA mount) was adjusted to allow access to the controls of the KH 150. The order numbers here are unchanged.
