Klein + Hummel O 410 Active Studio Monitor - Single – No Longer Available

Back in 1967, Klein + Hummel launched the world’s first active multi-channel studio monitor, the OY. The O 410 represents the latest incarnation of the many technologies pioneered by Klein + Hummel during the intervening 40 years. Engineering excellence applied to all aspects of the O 410 design brings a new benchmark in audio reproduction quality. A waveguide featuring Mathematically Modeled Dispersion™ (MMD™), flexible acoustical controls, various input options, and an extensive mounting hardware range allow the O 410 to be used in diverse acoustical conditions, with any source equipment, and in a wide variety of physical locations.

The O 410 has been designed for use as a mid-field or main monitor. It is particularly well-suited for use in music, broadcast, and post production studios for tracking, mixing, and mastering. The O 410 can be used free-standing or flush mounted into a wall, and, in multichannel systems, can be mixed freely with other loudspeakers in the Klein + Hummel range.

Features:

Mid Sized Three-Way System -

• The most important part of the frequency spectrum is reproduced by a separate midrange driver
• Extremely low harmonic and intermodulation distortion results in clean sounding audio reproduction
• Exceptionally neutral sound stage from 30 Hz to 24 kHz (±3 dB)
• Ideal cabinet materials with excellent self-damping properties
• Structural resonances avoided using LRIM™ (Low Resonance Integral Molding™)
• Vented enclosure extends bass response, even at very high output
• Modern-looking design with optional grille
• Extensive accessories allow for a multitude of installation possibilities
• Magnetically shielded for use next to CRT screens

Mathematically Modeled Dispersion™ (MMD™) - 

• Three stage design process:
• Waveguide is mathematically modeled before physical prototypes are realized,
• Physical prototypes are measured under anechoic conditions to verify theoretical performance,
• Extensive listening tests correlate objective measurements and subjective perception
• Wide horizontal directivity gives increased freedom of movement along the mixing console
• Narrow vertical directivity reduces the effect of early reflections off the console surface
• MMD™ is easily rotated in the field when horizontal mounting the cabinet
• Perfect directivity pattern leads to a smooth power response

Advanced Electronics -

• Transformer balanced input stage (TIM 1) equipped with special distortion reduction crossover function
• Q 16, 24 bit, 20, 216 kHz digital input stage (DIM 1) for AES3, AES 3id and S/P-DIF signals
• Q Electronics can be remotely accessed when the cabinet is flush mounted (REK 1 and CP 2, CP 5, CP 10, CP 15, CP 20, CP 25, or CP 30)
• Integrated electronic limiter for each driver
• Hybrid class A-B amplifiers, employed for their best overall performance, are also protected
• Active three-way crossover with 24 dB/oct. slopes
• Input options give flexibility without burdening basic product:
• Transformer balanced input stage equipped with special distortion reduction crossover function,
• 16, 24 bit, 20, 216 kHz digital input stage for AES3, AES 3id and S/P-DIF signals,
• XLR and BNC inputs, and a BNC output for flexible and robust interconnectivity
• Display for signal type, protect, and digital status is integrated into the MMD™, together with a K+H logo
• Controls adapt the monitor’s response to compensate for the loudspeaker’s environment:
• Bass, mid and treble controls for specific and common acoustical issues,
• Parametric EQ for low-frequency corrections
• Accelerated Heat Tunneling™ (AHT™) ensures effective amplifier cooling whether the cabinet is mounted vertically or horizontally.
• Electronics can be remotely accessed when the cabinet is flush mounted
• Electronics can be remotely powered on with two modes of operation (0 V and 12 V trigger)
• Attention to detail in design results in low self-generated noise
