Genelec 8050A - Manual (Page 4)

Treble tilt control
Treble tilt (third switch group from the left)
allows adjusting the treble response above
5 kHz by +2, -2, or -4 dB, which can be used
for correcting an excessively bright or dull
sounding system.
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.
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.
Maintenance
No user serviceable parts are to be found
within the loudspeaker cabinet or the ampli-
fier unit. Any maintenance or repair of the
loudspeaker should only be undertaken by
qualified service personnel.
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:
1. Servicing and adjustment must only
be performed by qualified service
personnel. The loudspeaker must not be
opened.
2. Do not use this product with 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.
4. Note that the amplifier is not
completely disconnected from the AC
mains service unless the mains power
cord is removed from the amplifier or the
mains outlet.
5. Free flow of air behind the loudspeaker
is necessary to maintain sufficient cooling.
Do not obstruct airflow around the
loudspeakers.
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.
