Genelec 8040A and 8050A Monitoring Systems
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.

Minimum clearances
Sufficient cooling for the amplifier and func-
tioning of the reflex port must be ensured if
the loudspeaker is installed in a restricted
space such as a cabinet, or integrated into
a wall structure. The surroundings of the
loudspeaker must always be open to the
listening room with a minimum clearance of
5 centimeters (2") behind, above and on both
sides of the loudspeaker. The space adjacent
to the amplifier must either be ventilated or
sufficiently large to dissipate heat so that the
ambient temperature does not rise above
35 degrees Celsius (95°F).
Mounting options
The vibration insulating Isolation Positioner/
Decoupler™ (Iso-Pod™) table stand allows
tilting of the loudspeaker for correct align-
ment of the acoustic axis. The stand can be
attached to three mounting points allowing
vertical and symmetrical horizontal position-
ing (see figures 1 and 4).
Genelec 8040A and 8050A can be fitted
to Omnimount® Series 30 (8040A) and 60
(8050A) and König & Meyer loudspeaker
mounts on two sets of M6x10 mm threaded
holes on the back of the enclosure. On the
base of the enclosure is an M10x10 mm
Figure 3. RCA t o XLR cable
threaded hole which can be used for secur-
ing the loudspeaker to its base. Do not use
this thread for mounting the loudspeaker on
a microphone stand which has a 3/8" UNC
thread.
Setting the input sensitivity
The input sensitivity of the loudspeakers can
be matched to the output of the mixing con-
sole, or other source, by adjusting the input
sensitivity control on the rear panel (see
figure 1). A screwdriver is needed for the
adjustment. The manufacturer’s default set-
ting for this control is -6 dBu (fully clockwise)
which gives an SPL of 100 dB @1m with
-6 dBu input level.
Setting the tone controls
The frequen cy response of the system
may also have to be adjusted to match the
acoustic environment. The adjustment is
carried out by setting the three tone con-
trol switch groups "treble tilt", "bass tilt"
and "bass roll-off" on the rear panel of the
amplifier. There is also a special "desktop
low frequency" tone control which gives an
attenuation of 4 dB at 160 Hz to compen-
sate the effect of a mixing console, desk or
other reflective surface between the listener
and the loudspeaker. The factory settings
for these controls are all "OFF" to give a flat
anechoic response.
Bass roll-off control
Bass roll-off (first switch group from the left)
affects the low frequency roll-off of the loud-
speaker and attenuates its energy output
near the cut-off frequency. Attenuation levels
of -2, -4 or -6 dB can be selected.
Desktop low frequency control
The desktop low frequency control (fourth
switch of first switch group from the left)
att enuates the bass frequencies around
160 Hz by 4 dB (see figures 8 and 10). 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 similar reflective surface.
Bass tilt control
The bass tilt control switches (second switch
group from the left) offer three attenuation
levels for the bass response below 800 Hz,
usually necessar y when the l oudspeak-
ers are placed near room boundaries. The
attenuation levels are -2 dB, -4 dB and
-6 dB.

Safety considerations
Although the 8040A and 8050A have been
designed in accordance with international
An acou stic measur ing system su ch as
MLSSA or WinMLS is recommended for
analyzing the effects of the adjustments,
however, careful listening with suitable test
safety standards, to ensure safe operation
and to maintain the loudspeaker under safe
operating conditions, the following warnings
and cautions must be observed:
recordings can also lead to good results if a
test system is not available. Table 1 shows
some typical settings in various situations.
Figures 8 and 10 show the effect of the con-
trols on the anechoic response.
Always star t adjustment by setting all
switches to "OFF” position. Then set only
one switch per group to the "ON" position to
select the desired adjustment. If more than
one switch is set to "ON" (within one switch
group) the attenuation value is not accurate.
Measure or listen systematically through
the different combinations of settings to find
the best frequency balance.
1. Ser vicing and adjustment must only
be pe r fo r m ed by qu a lif i ed ser vi c e
personnel. The loudspeaker must not be
opened.
2. Do not use this product wi th an
unearthed mains cable as this may lead to
personal injury.
3.
To prevent fire or electric shock, do not
expose the unit to water or moisture. Do
not place any objects filled with liquid,
such as vases on the loudspeaker or near
it.

Maintenance
No user ser viceable parts are to be found
within the loudspeaker cabinet or the ampli-
mains service unless the mains power
cord is removed from the amplifier or the
mains outlet.
