General
Description
As consumer technology advances at
ever faster rates, professional technology increasingly finds
itself trying to keep up. An example of this is the advent of the
Blu-ray and other high definition formats that have increased the
audio channel count to 7.1.
The O 870 is an answer to these new demands by offering a new 7.1
High Definition Bass Manager™. This is compatible with all
standard consumer formats from mono through to the latest 7.1 HD
systems. Eight channels of analog or an optional 8-channel, 24-bit,
192 kHz digital input card ensures flexible interconnectivity for
modern studios. Four-mode LFE-channel processing guarantees
compatibility across all formats and industries. Forth-order
crossovers and flexible acoustical controls allow for seamless
system integration. Built-in volume control and a hardware remote
control allows for centralized system control independent of the
source, and the electronics can be remote located to reduce
cabling
The latest amplifier technology and acoustical components have been
used to ensure the most accurate sound reproduction possible.
Robust drivers, a rock-solid cabinet, and carefully designed ports
guarantee a tight, articulate, and distortion-free low frequency
reproduction, even at high replay levels. Using the sum output,
Plane Wave Bass Array™ (PWBA™) techniques acoustically
improves lateral consistency in the listening area. The Bass
extends down to 18 Hz.
The O 870 subwoofer is designed to complement our extensive range
of monitors, and can be used on its own, or daisy-chained to make
larger systems capable of higher SPL. The O 870 can be used in
music, broadcast, and post production studios for tracking, mixing,
and mastering. The cabinet can be positioned next to a wall or
flush mounted into a wall due to the front mounted port, and can be
mixed freely in multichannel systems with other loudspeakers from
our range
