Klein & Hummel O410
Active Mid-Field Speaker

O410

FEATURES:

Mid Sized 3-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

• 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
