(click thumbnail)O 810Klein + Hummel is preparing its O 810 and O 870 subwoofers for a Vegas debut. Each can be used as a unit dedicated to reproducing the LFE channel, or as a way to provide low-frequency extension and increased maximum SPL for the main loudspeakers.
The 7.1 Channel High Definition Bass Manager is compatible with formats from mono to 7.1 high-definition systems like Blu-ray and HD-DVD. Eight channels of analog, or an optional 8-channel 24-bit 192 kHz digital input card, enable interconnectivity for modern studios. Four-mode LFE channel processing ensures compatibility across all formats, says the company. Volume control allows for centralized system replay level adjustment independent of the source. Electronics can be remote-located to reduce cabling.
K+H says the design of the drivers, cabinet and ports provides distortion-free low-frequency reproduction down to 18 Hz, even at high-replay levels. Using the sum output, Plane Wave Bass Array (PWBA) techniques can acoustically improve lateral consistency in the listening area.
The O 810 and O 870 can be used in music, broadcast and post-production studios for tracking, mixing and mastering. They may be positioned next to a wall or flush-mounted into a wall, and can be mixed in multi-channel systems with other loudspeakers from the Klein + Hummel range.
Klein + Hummel is a Sennheiser Group company.
