General description

The bi-ampliﬁed GENELEC 8020C is a 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 loud-

speaker, 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 Wave-

guideTM (DCWTM), this design provides excellent fre-

quency balance in difﬁcult acoustic environments. If

necessary, the bass response of the 8020C can be

extended with a Genelec subwoofer.

Positioning the loudspeaker

Each 8020C is supplied with an integrated ampli-

ﬁer unit, mains cable and an operating manual. After

unpacking, place the loudspeaker in its required lis-

tening position, taking note of the line of the acoustic

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 8020C is located on the back

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

earthed mains connection with the supplied mains ca-

ble. Never connect the loudspeaker to an unearthed

mains supply or using an unearthed mains cable. Au-

dio input is via a 10 kOhm balanced female 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

8020C to the loudspeaker outputs of a power ampli-

ﬁer or an integrated ampliﬁer or receiver.

Once the connections have been made, the

loudspeakers are ready to be switched on.

ISSTM autostart function

When the power switch on the back panel of the

loudspeaker is set to “ON”, the Intelligent Signal

SensingTM (ISSTM) autostart function of the 8020C is

active. Automatic powering down to standby mode

happens after a certain time when playback has

ended. The power consumption in standby mode is

typically less than 0.5 watts. The playback will auto-

matically resume once an input signal is detected

from the source.

There is a slight delay in the automatic power-

ing up. If this is undesirable, the ISS

TM function can

be disabled by setting the “ISS DISABLE” switch

on the back panel to “ON” position. In this mode,

the monitor is powered on and off using the power

switch on the back panel.

Volume control

The input sensitivity of the 8020C can be matched

to the output of the signal source by adjusting the

volume control on the front panel.

Setting the tone controls

The frequency response of the Genelec 8020C

can be adjusted to match the acoustic environment

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 recommended

for analyzing the effects of the adjustments, how-

ever, careful listening with suitable test recordings

can also lead to good results. Table 1 shows some

examples of typical settings in various situations.

Figure 4 shows the effect of the controls on the

anechoic response.

Treble Tilt

reble Tilt control (switch 2) attenuates the treble

response of the loudspeaker at frequencies above

5 kHz by 2 dB, which can be used for smoothening

down an excessively bright sounding system.

Bass Tilt

Bass Tilt control offers three attenuation levels

for the bass response of the loudspeaker below

2 kHz, usually necessary when the loudspeakers

are placed near a wall or other room boundaries.

The attenuation levels are -2 dB (switch 4 “ON”), -4

dB (switch 5 “ON”) and -6 dB (both switches “ON”).

Bass Roll-Off

Bass Roll-Off (switch 3) activates high-pass ﬁlter-

ing at 85 Hz to complement the low-pass ﬁlters of

a Genelec 7050A or 7050B subwoofer. This switch

should always be set to “ON” when using the 8020C

with these subwoofers.
