Klein & Hummel O300DL

NOTE: O300DR model shown above.

FEATURES:

3-way system design

• The most important part of the frequency spectrum is reproduced by a separate midrange driver
• Extremely low-distortion reproduction
• Exceptionally neutral sound stage from 40 Hz to 20 kHz
• No standing waves in the enclosure and no bass driver cone break-up

Unconventional enclosure concept

• Very compact enclosure constructed using ideal materials with excellent self-damping properties
• Structural resonances avoided using LRIM (Low Resonance Integral Molding)
• Very accurate bass reproduction due to sealed enclosure
• Acoustic centers of loudspeaker positioned on one plane
• Homogenous front baffle with no diffraction or acoustical discontinuities
• Wider effective listening area for main monitor when horizontally installed
• Modern-looking design with optional baffle cover/grill
• Extensive accessories allow for a multitude of installation possibilities
• Magnetically shielded for use next to CRT screens

Functional waveguide

• 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
• Perfect directivity pattern leads to a smooth power response

Advanced Electronics

• Integrated electronic limiter for each driver
• Active three-way crossover with 24 dB/oct. slopes
• Transformer balanced input equipped with special distortion reduction crossover function
• Power and overload/limiter-display integrated into the front panel K+H logo
• Controls adapt the monitor’s response to compensate for the roomlocation

O 300 D

• Additional 24-bit and 32-96 kHz digital input for AES/EBU, AES 3id and S/P-DIF
• Input connector for external Pro C 28 FIR digital controller
• Transformer balanced analog input
