General description
The bi-amplified GENELEC 8020D 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 loudspeaker, it contains drivers, power amplifiers,
active crossover filters and protection circuitry.
The MDE™ (Minimum Diffraction Enclosure™)
loudspeaker enclosure is made of die-cast aluminium and
shaped to reduce edge diffraction. Combined with the
advanced Directivity Control Waveguide
TM
(DCW
TM
), this
design provides excellent frequency balance in difficult
acoustic environments. If necessary, the bass response of
the 8020D can be extended with a Genelec subwoofer.
Positioning the loudspeaker
Each 8020D 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 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
8020D 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
unearthed mains supply or using an unearthed mains cable.
The mains input accepts a wide range of voltages: 100-240
V AC 50-60 Hz.
Audio 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 8020D to the
loudspeaker outputs of a power amplifier or an integrated
amplifier or receiver.
Once the connections have been made, the
loudspeakers are ready to be switched on.
ISS
TM
autostart function
When the power switch and the “ISS” switch on the back
panel of the loudspeaker are set to “ON”, the Intelligent
Signal Sensing
TM
(ISS
TM
) autostart function of the 8020D
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 automatically resume once an
input signal is detected from the source.
There is a slight delay in the automatic powering up. If
this is undesirable, the ISS
TM
function can be disabled by
setting the “ISS” switch on the back panel to the “OFF”
position. In this mode, the monitor is powered on and off
using the power switch on the back panel.
Sensitivity control
The input sensitivity of the 8020D can be matched to the
output of the signal source by adjusting the rotary sensitivity
control on the back panel.
Setting the tone controls
