From Neumann USA
The KH 350 expands Neumann’s portfolio into true midfield monitoring, delivering the power, low frequency authority and control required for listening distances ranging from 1.2 to 3 m (4 to 10 ft) and immersive production environments. As it shares Neumann’s consistent tonal DNA, the KH 350 may be combined with other KH-Line monitors in immersive setups.
The KH 350 impresses with deep and powerful low-end response, enormous headroom, and exceptional linearity across the entire musical spectrum (32 Hz – 20 kHz ±1.25 dB).
Neumann’s Mathematically Modeled Dispersion (MMD) waveguide shapes the sound radiation to deliver precise and consistent dispersion throughout the room. This ensures stable imaging and greatly reduces unwanted reflections, supporting accurate monitoring even at longer listening distances while remaining fully capable in nearfield setups.
Built on Neumann’s advanced DSP engine, the KH 350 supports MA 1 Automatic Monitor Alignment, offering highly accurate frequency and phase optimization. Analog and digital AES3id inputs (BNC) integrate seamlessly with Neumann’s KH subwoofers and monitor control solutions, enabling flexible system scalability from stereo to immersive environments.
Industry leading tight manufacturing tolerances ensure consistent unit to unit matching and predictable performance across multi monitor installations: perfect translation to all playback systems for music production, mixing, and mastering in stereo or immersive formats, as well as film scores, broadcast, and post production workflows.
Features:
- Reliable full range reference with excellent translation
- Precise directivity for nearfield and midfield distances
- Deep LF extension (30 Hz ±3 dB) with impressive headroom
- DSP engine for improved performance and MA 1 room correction
- Ideal for immersive LCR and larger multichannel systems
- Seamless integration with network enabled KH subwoofers
