DescriptionThe perfect
low-frequency complement
 A profusion of developments in audio and modern digital
technologies are placing new demands today on active monitoring.
Multi-channel productions require high-quality studio monitors and
active subwoofers that can be used for both matrix-encoded formats
and discrete formats as well.
 The O 800 matches these new demands of modern studio technology
precisely. Whether as the perfect low-frequency complement to all
our monitor systems, or as an LFE unit (Low Frequency Effect), the
O 800 will fit every possible combination of surround system
specified today.
 Active studio monitors from us have developed a reputation for
their seamlessly integrated sound. With the advent of the O 800 it
is now possible to assemble entire monitoring systems for different
sizes of studios with a smoothly uniform frequency response that
ranges from 30 Hz to 20 kHz.
 The extraordinary dynamics, incredible accuracy and precise stereo
soundstage of our monitors provide audio engineers with the
confidence they need to make sure critical judgments of
multi-channel audio material.
 Well-connected
 A new installation of a complete system from us incorporating the O
800 subwoofer is easy to set up; expanding an existing system would
be just as easy:
 With its three balanced inputs (Left, Center, Right), the O 800
offers all the connections necessary for operating in mono, stereo,
stereo-plus-center-channel mode, Dolby® Surround, Dolby®
Surround EX and front or rear channels with 5.1. The center input
can also be switched to “Sub Direct” to use the
subwoofer for the effect channel (LFE) with discrete formats. For
6.1 or 7.1 installations, it would be logical to use two or, in
some cases, three O 800 subwoofers to ensure that the recording is
reproduced with utmost accuracy.
 The balanced high-pass outputs (Left, Center, Right) are for
connecting the corresponding front and rear monitors. The subwoofer
can be muted whenever necessary either directly via the rear-panel
bypass switch or remotely with an on/off footswitch connected to
the ¼” Bypass jack. Two controls - a continuously
variable phase-adjustment control (0 - 180º) and a separate
level control - permit you to set up the subwoofer at any location
in the studio you wish. The 4-step low-cut filter (30, 40, 50, or
60 Hz) helps match the subwoofer to the acoustics of a given room,
and also make it possible to simulate a system not as rich in bass
in order to determine how well a given mix will translate to such a
system.
 No
compromise long excursion 10” driver
 The heart of the O 800 is the new low-frequency driver which was
developed for this specific enclosure and application. The
driver’s extremely long excursion of ±20 mm enables it
to produce bass with remarkably low distortion.
 The patented Nomex®/Kevlar®-composite cone with its high
degree of self-damping and the rearvented voice coil design both
contribute to the production of very high sound-pressure levels
with absolutely minimal power compression. The implementation of
these new technologies yields uncommonly articulate bass all the
way down to 27 Hz.
 The low-frequency driver is in an aluminium basket designed for
maximum air flow. It is also magnetically shielded, freeing you to
place the subwoofer on the floor right next to a personal computer
or immediately below a video monitor, without the speaker having an
adverse effect on either one.
 New enclosure with years of
experience behind it
 Thanks to its extremely solid construction (MDF) and its large
bass-reflex port, the O 800 enclosure eliminates unwanted resonance
and air noise, and produces taut, articulate bass with excellent
impulse response. The finish is a high-quality scratch-resistant
textured enamel that makes the cabinet an attractive, with a
professional appearance. A sturdy, fine-mesh wire grille with
excellent acoustic behavior serves to protect the loudspeaker cone
from mechanical damage.
 Due to its relatively small footprint, there should be no problem
finding a place for the O 800 in practically any studio.
 Powerful
electronics
 The powerful amplification developed specifically for the O 800 has
its roots in years of our engineering expertise. This amplifier is
one of high continuous power output, rugged reliability and superb
technical per-formance.
 The O 800 includes sophisticated “True-Clipping”
circuitry which, as it senses the onset of distortion,
automatically limits the signal sent to the amplifier, and reliably
protects both the loudspeaker and the amp from being overdriven and
possibly damaged. The high-pass/low-pass crossover occurs at
precisely 90 Hz using an integrated active Linkwitz-Riley frequency
crossover with a slope of 24 dB/octave.
