Neumann.Berlin has announced the expansion of its line of studio monitors with the new KH 150, a bi-amplified, DSP-controlled loudspeaker equipped with the same high-resolution tweeter as all of the company’s monitor models joined by a newly developed 6.5-inch woofer designed to offer low distortion and high SPL capability.
The KH 150 is designed to provide a flat frequency response from 39 Hz to 21 kHz (±3 dB) and is recommended for applications such as broadcast and music production that includes styles requiring a deep low-end and/or elevated listening levels such as urban music, EDM, and film scoring.
“The KH 150 closes the gap between the KH 120 and the KH 310, but it does far more than that,” explains Portfolio Manager Stephan Mauer. “Its internal DSP engine offers many benefits such as a phase linearized crossover and a new level 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.”
Digital electronics also allow the KH 150 to be calibrated via Neumann’s MA 1 automatic monitor alignment (sold separately). “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,” states Neumann CEO Ralf Oehl. “In our pursuit of sonic perfection, we not only optimize every parameter of the loudspeaker itself, we also include the greatest variable: the listening environment. The KH 150’s DSP engine perfectly integrates with Neumann’s game-changing MA 1 automatic monitor alignment for best possible sound in any room.”
Neumann states that its engineers developed a patent-pending amplifier technology that is designed to provide high-quality audio performance with the energy efficiency of Class D. Although the KH 150’s amplifiers deliver stated audio power of up to 145 watts to the 6.5-inch woofer and 100 watts to the 1-inch tweeter, they are rated to consume 17 watts at idle. Auto-standby reduces power consumption to 0.3 watts when the KH 150 has not been used for a while, but can be deactivated.
The monitor offers analog and digital inputs (S/PDIF), and will also be available in an AES67 variant with 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.
