6020A

General description

The bi-amplified GENELEC 6020A is an extreme-

ly compact two way active loudspeaker designed

for home theaters and multimedia applications.

As an active loudspeaker, it contains drivers,

power amplifiers, active crossover filters and pro-

tection circuitry. The MDE™ (Minimum Diffraction

Enclosure™) loudspeaker enclosure is made of

die-cast aluminium and shaped to reduce edge

diffraction. Combined with the advanced Direc-

tivity Control WaveguideTM (DCWTM), this design

provides excellent frequency balance in difficult

acoustic environments. If necessary, the bass re-

sponse of the 6020A’s can be extended with a

Genelec 5050A subwoofer.

Positioning the loudspeaker

Each 6020A is supplied with an integrated am-

plifier unit, mains cable and an operating man-

ual. After unpacking, place the loudspeaker in

its required listening position, taking note of the

line of the acoustic axis. The axes of all loud-

speakers should converge at ear height at the

listening position (see Figures 1 and 2).

Connections

Before connecting up, ensure that the volume

control potentiometer on the front panel is turned

fully counter-clockwise to the stand-by setting.

Connect the loudspeaker to an ear thed mains

connection with the supplied mains cable. Never

connect the loudspeaker to an unearthed mains

supply or using an unearthed mains cable.

The 6020A has two parallel 10 kOhm au-

dio input connectors: a balanced XLR and an

unbalanced RCA. For longer cable connection

lengths (>10 m or >30 ft) a balanced line con-

nection is recommended as it offers better im-

munity to external interference. However, the

RCA connection method is more commonly

available and usually works as well for shorter

connection lengths in less electrically noisy

environments. Do not use both inputs at the

same time. Consult your Genelec dealer for the

choice of signal cables. Once the connections

have been made, the loudspeakers are ready

to be switched on.

Volume control, Autostart and

stand-by switching

The input sensitivity of the loudspeakers can be

matched to the output of the preamp/proces-

sor by adjusting the volume control on the front

panel. When the volume control knob is turned

fully counter-clockwise, the 6020A goes into

stand-by mode. The loudspeaker can be left in

stand-by mode whenever it is not used, how-

ever, it is only completely disconnected from the

mains power when the mains cable is discon-

nected.

The 6020A is also equipped with a signal-

sensing Autostart function for automatic switch-

ing between “on” and “stand-by” modes. Auto-

star t is activated by turning switch 1 (AUTO-

START) on the back panel to “ON”. Autostart

turns the amplifier to stand-by mode if there is

no signal present for about 30 minutes. When

the signal returns the amplifier switches on im-

mediately and the loudspeaker functions nor-

mally.

Setting the tone controls

The frequency response of the Genelec 6020A

can be adjusted to match the acoustic environ-

ment by setting the tone control switches on

the rear panel. The controls are “Treble Tilt” and
