and the loudspeaker. The factory settings
for these controls are all "OFF" to give a flat
anechoic response.
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).
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.
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.
Desktop low frequency control
The desktop low frequency control (fourth
switch of first switch group from the left)
attenuates 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.
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).
Setting the tone controls
The frequency 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
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 necessary when the loudspeak-
ers are placed near room boundaries. The
attenuation levels are -2 dB, -4 dB and
-6 dB.
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

Safety considerations
Although the 8040A and 8050A have been
designed in accordance with international
safety standards, to ensure safe operation
and to maintain the loudspeaker under safe
operating conditions, the following warnings
and cautions must be observed:
WARNING!
Genelec 8040A and 8050A loudspeakers are
capable of producing sound pressure levels
in excess of 85 dB, which may cause perma-
nent hearing damage.
An acoustic measuring system such as
MLSSA or WinMLS is recommended for
analyzing the effects of the adjustments,
however, careful listening with suitable test
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.
8040A Accessories
1. Servicing and adjustment must only
be performed by qualified service
personnel. The loudspeaker must not be
opened.

Always start 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.

personal injury.
