General description

The bi-ampliﬁed GENELEC 8020B is an extremely

compact two way active monitoring loudspeaker

designed for near ﬁeld monitoring, mobile vans,

broadcast and TV control rooms, surround sound

systems, home studios, multimedia applications and

also for use with computer soundcards. As an active

loudspeaker, it contains drivers, power ampliﬁers,

active crossover ﬁlters and protection circuitry.

The MDE™ (Minimum Diffraction Enclosure™)

loudspeaker enclosure is made of die-cast alumin-

ium and shaped to reduce edge diffraction. Com-

bined with the advanced Directivity Control Wavegui-

deTM (DCWTM), this design provides excellent fre-

quency balance in difﬁcult acoustic environments. If

necessary, the bass response of the 8020B’s can be

extended with a Genelec 7050B subwoofer.

Positioning the loudspeaker

Each 8020B monitor is supplied with an integrated

ampliﬁer unit, mains cable and an operating manual.

After unpacking, place the loudspeaker in its required

listening position, taking note of the line of the acous-

tic axis. The axes of all loudspeakers should converge

at ear height at the listening position (see Figure 1).

Connections

Before connecting up, ensure that the loudspeakers

and the signal source have been switched off. The

power switch of the 8020B is located on the back

panel (see Figure 3). Connect the loudspeaker to an

earthed mains connection with the supplied mains

cable. Never connect the loudspeaker to an un-

earthed mains supply or using an unearthed mains

cable. Audio input is via a 10 kOhm balanced fe-

male XLR connector. An unbalanced source may

be used as long as pin 3 is grounded to pin 1 at

the unbalanced source connector (see Figure 2).

Never connect the 8020B to the loudspeaker out-

puts of a power ampliﬁer or an integrated ampliﬁer

or receiver.

Once the connections have been made, the

loudspeakers are ready to be switched on.

Volume control

The input sensitivity of the loudspeakers can be

matched to the output of the mixing console or other

signal source by adjusting the volume control on the

front panel.

Setting the tone controls

The frequency response of the Genelec 8020B

can be adjusted to match the acoustic environ-

ment by setting the tone control switches on the

rear panel. The controls are “Treble Tilt”, “Bass

Tilt” and “Bass Roll-Off”. An acoustic measuring

system such as WinMLS or comparable is recom-

mended for analyzing the effects of the adjust-

ments, however, careful listening with suitable

test recordings can also lead to good results if

a test system is not available. Table 1 overleaf

shows some examples of typical settings in vari-

ous situations. Figure 4 shows the effect of the

controls on the anechoic response.
