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

studios. 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

leads 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 place the 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.

Genelec 8040A and 8050A Monitoring Systems

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, careful

listening with suitable test recordings can

also lead to good results if a test system is

not available. Table 1 shows some typical set-

tings in various situations. Figures 8 and 10

show the effect of the controls on the ane-

choic 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:

• Servicing and adjustment must

only be performed by qualiﬁed service

personnel. The loudspeaker enclosure

must not be opened.

• Do not use this product with an

unearthed mains cable or a mains

connection without the protective earth

contact 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.

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.

Guarantee

Genelec 8040A and 8050A are supplied with

two year guarantee against manufacturing

faults or defects that might alter the perfor-

mance of the loudspeakers. Refer to supplier

for full sales and guarantee terms.
