8050B Active Monitoring System
The Genelec 8050B is a powerful bi-amplied
active monitor system with a wide frequency
response and high SPL capability. The 8050B
takes full advantage of the unconventional
design and advanced technologies of Genel-
ec’s 8000 Series loudspeaker range. The all-
aluminium Minimum Diffraction Enclosure™
(MDE™) and advanced Directivity Control
Waveguide™ (DCW™) technologies are care-
fully matched with advanced amplier and
electronic circuitry and the latest driver gen-
eration. Bass response extends down to an
astounding 35 Hz, while distortion is extremely
low due to a unique new rear reflex port
design. The system's excellent directivity char-
acteristics and accurate imaging as well as
the exible mounting options make the 8050B
the perfect monitoring tool for a wide range of
applications.
The 8050B has been specially designed
to have considerable LF extension so it can
be used as main speaker for most situations.
However if greater SPL's and an even lower
cutoff frequency are required, it can be com-
plemented with a Genelec subwoofer.
Integrated construction
The 8050B is very easy to set up and use,
the only connections required are the mains
supply and the line level input. The input is
made via a balanced female XLR connec-
tor. The input sensitivity of the 8050B can be
adjusted for easy level matching with other
audio equipment.
The integrated design allows the ampliers
and the drivers to be calibrated as a single
unit, eliminating the effects of component tol-
erances and ensuring consistent production
quality.
Crossover lters
The amplier unit contains an active cross-
over, a feature more commonly used in large
and expensive control room monitors. This
is the ideal method for dividing the input
signal between the driver units. The active
crossover allows the overall response of the
system to be optimized to an extent impos-
sible with a passive system. To maintain uni-
form frequency balance in differing acoustic
environments, special calibrated controls are
included in the active crossover network.
These controls include “treble tilt”, “bass tilt”
and “bass roll-off” functions.
A new function, “desktop low frequency”
control attenuates the bass frequencies
around 160 Hz by 4 dB. This feature is
designed to compensate for the boost often
occurring at this frequency range when the
loudspeaker is placed upon a meter bridge,
table or a similar reective horizontal sur-
face.
Ampliers
The bass and treble amplifiers produce
150 and 120 watts of output power each, with
very low THD and IM distortion values. Each
amplier is designed to precisely match the
driver it is connected to, thus ensuring the
highest subjective sound quality currently pos-
sible. The amplier unit also contains a pro-
tection circuit that monitors the output levels
and prevents any damage to the drivers. This
makes the system immune to overloads and
spurious signals.
Drivers
A 25 mm (1") metal dome tweeter is loaded
by an advanced DCW™ waveguide, which is
integrated into the one piece front bafe. The
improved DCW™ provides superior directivity
charcteristics and perfect matching between
the drivers.
The 205 mm (8") bass cone driver is
mounted in a newly designed bass reex
enclosure. The long, ow optimized reex
tube has a large cross sectional area and
terminates with a wide are at the back of
the enclosure.
Protective grilles are positioned in front of
both drivers. Magnetic shielding is standard
on the 8050B. Shielding is vital for applica-
tions such as video post production, where
stray magnetic elds must be minimized.
