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

Active studio reference monitor - three-way system - magnetically shielded - tri-amplified
MFR# 502249

Product Description

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

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!

I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.
