8000 Series
System
The GENELEC 8040A and 8050A are
two way active monitoring loudspeakers
designed to produce high SPL output, low
coloration and broad bandwidth in a small
enclosure size. They are suitable for a wide
variety of tasks, such as near field monitor-
ing, mobile vans, broadcast and TV control
rooms, surround sound systems and home
stu dios. Designed as active loudspeak-
ers, they contain drivers, power amplifiers,
active crossover filters and protection cir-
cuitry. The Minimum Diffraction Enclosure™
(MDE™) and advanced Directivity Control
Waveguide™ (DCW™) technologies pro-
vide excellent frequency balance even in
difficult acoustic environments.
Drivers
The bass driver dimensions are 165 mm (6
1/2”) and 205 mm (8") for 8040A and 8050A
respectively. The long, flow optimized reflex
tube has a large cross sectional area and
terminates with a wide flare at the back of
the enclosure. The high frequency driver is a
19 mm (3/4”) metal dome on the 8040A and
a 25 mm (1") metal dome on the 8050A. Both
drivers are magnetically shielded.
Crossover
The active crossover network consists of two
parallel bandpass filters. The crossover fre-
quency is 3.0 kHz on the 8040A and 1.8 kHz
on the 8050A. The active crossover controls
("treble tilt", "desktop low frequency", "bass
tilt" and "bass roll-off") allow precise match-
ing of the loudspeakers to any room environ-
ment.
Amplifiers
The amplifier unit is mounted in the rear of
the loudspeaker enclosure. The unit incor-
porates special circuitry for driver thermal
overload protection. Variable input sensitiv-
ity allows accurate level matching to console
output section.
Connections
Each loudspeaker is supplied with a mains
cable and an operating manual. Before con-
necting up, ensure that the mains switch is off
(see figure 1). Audio input is via a 10 kOhm
balanced XLR connector, but unbalanced
lea ds may be used as long as pin 3 is
grounded to pin 1 of the XLR (see figure 3).
Once the connections have been made, the
loudspeakers are ready to be switched on.
Mounting considerations
Align the loudspeakers correctly
Always plac e t he loudspeakers so that
their acoustic axes (see figure 2) are aimed
towards the listening position. Vertical place-
ment is preferable, as it minimises acoustical
cancellation problems around the crossover
frequency.
Maintain symmetry
Check that the loudspeakers are placed
symmetrically and at an equal distance from
the listening position. If possible, place the
system so that the listening position is on the
centerline of the room and the loudspeakers
are placed at an equal distance from the cen-
terline.
Minimise reflections
Acoustic reflections from objects close to the
loudspeakers like desks, cabinets, computer
monitors etc. can cause unwanted colouration
and blurring of the sound image. These can
be minimised by placing the loudspeaker clear
of reflective surfaces. For instance, putting the
loudspeakers on stands behind and above the
mixing console usually gives a better result
than placing them on the meter bridge.
