Neumann Launches KH 150 Studio Monitor with AES67 and DSP Control
Neumann has introduced the KH 150 powered studio monitor, featuring a 6.5" woofer, DSP-controlled electronics for linear phase, and high SPL, designed for professional audio production. The monitor also offers an AES67 variant, providing interoperability with broadcast standards like ST 2110 and RAVENNA, and integrates with Neumann's MA 1 automatic monitor alignment system.
Key Takeaways
- The KH 150 includes a 6.5" woofer in a bass-reflex cabinet, delivering low-frequency performance down to 39 Hz.
- DSP-controlled electronics enable a linear phase response and tonal consistency within ±0.8 dB tolerance.
- An AES67 variant features redundant audio network ports, compatible with broadcast standards such as ST 2110, ST 2022-7, and RAVENNA.
- The monitor integrates with Neumann's MA 1 automatic monitor alignment system for room-specific calibration.
- The KH 150's amplifier delivers 145W to the woofer and 100W to the tweeter, consuming 17W when idle.
Why It Matters
The introduction of the Neumann KH 150, particularly its AES67 integration, provides professional audio environments with a more flexible and robust monitoring solution. This direct support for broadcast audio-over-IP protocols streamlines workflows in facilities utilizing ST 2110 or RAVENNA. As broadcast and production infrastructures continue their shift to IP, the availability of studio-grade monitors with native AES67 connectivity reduces the need for external converters and simplifies network configuration, offering clear advantages in system design and scalability. Watch for wider adoption of AES67 in production hardware as a benchmark for interoperability in professional audio setups.
Additional Context
The Neumann KH 150 fills a long-standing gap in the company's monitor lineup, sitting between the compact KH 120 and the larger, three-way KH 310, as noted by Sound On Sound (January 2023). Reviewers highlight its "near-flawless" performance for compact nearfield monitoring, offering an "utterly neutral and uncoloured tonal balance," and "brilliant stereo imaging," (Sound On Sound, January 2023). The monitor's DSP control is a significant factor in its performance, contributing to an exceptionally flat axial frequency response and low harmonic distortion, which is critical for accurate audio production (Music and Miscellany, January 2023). The integration of AES67 in a variant of the KH 150 is particularly relevant given the ongoing industry trend towards Audio over IP (AoIP) solutions. AES67 ensures interoperability between different AoIP protocols, including Dante and RAVENNA, making it a crucial standard for modern broadcast and production facilities. This built-in support eases deployment in complex networked audio environments, a feature that distinguishes the KH 150 from some competitors in its price range (Thomann UK product description). While the MA 1 automatic monitor alignment system is sold separately, its effectiveness in optimizing the monitor's performance for varying room acoustics is consistently praised, even in acoustically treated spaces (Sound On Sound, January 2023).
