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.
