Desktop low frequency control

The desktop low frequency control (fifth

switch of first switch group from the left)

attenuates the bass frequencies around

160 Hz by 4 dB (see figures 7 and 9). 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 sur-

face.

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.

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

WinMLS is recommended for analyzing the

effects of the adjustments, however, care-

ful 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 7 and 9 show

the effect of the controls 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 amplifier

unit. Any maintenance or repair of the loud-

speaker should only be undertaken by quali-

fied service personnel.

Safety considerations

Although the 8040B and 8050B 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:

• Servicing and adjustment must

only be performed by qualified service

personnel. The loudspeaker must not be

opened.

• Do not use this product with an

unearthed mains cable as this may lead

to personal injury.

• 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.

• 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.

• Free flow of air behind the

loudspeaker

is necessary to maintain sufficient cooling.

Do not obstruct airflow around the

loudspeakers.

• Do not expose the loudspeaker to

water or moisture. Do not place any

objects filled with liquid, such as vases on

the loudspeaker or near it.

WARNING!

Genelec 8040B and 8050B loudspeakers are

capable of producing sound pressure levels in

excess of 85 dB, which may cause permanent

hearing damage.
