General
The bi-amplified Genelec 4030B is an extremely
compact two way active loudspeaker designed for
fixed installations. As an active loudspeaker, it con-
tains drivers, power amplifiers, active crossover fil-
ters and protection circuitry. The 4030B is designed
for indoor use only, in temperatures between 15 to
35 degrees Celsius and relative humidity between
20 % and 90 %.
The MDE™ (Minimum Diffraction Enclosure™)
loudspeaker enclosure is made of die-cast alu-
minium and shaped to reduce edge diffraction.
Combined with the advanced Directivity Control
Waveguide
TM
(DCW
TM
), this design provides excel-
lent frequency balance in difficult acoustic environ-
ments.
Positioning the loudspeaker
Each 4030B is supplied with an integrated amplifier
unit, mains cable, a 5-pin connector for audio signal
and 12 V trigger voltage, a keyhole type wallmount
and an operating manual. After unpacking, place the
loudspeaker in its required listening position, taking
note of the line of the acoustic axis. The axis should
be pointed towards the center of the listening area.
Connections
Before connecting up, ensure that the loudspeakers
and the signal source have been switched off. The
power switch of the 4030B 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 con-
nector. The connector also has two pins for 12 V
trigger voltage for power switching. The current fed
into the 12 V trigger connection must not exceed
200 mA. The pin sequence of the connector is
shown in Figure 2.
Connect the signal cable and 12 V trigger volt-
age to the 5-pole plug provided with the loud-
speaker and secure the connections by tightening
the screws on each pole. Push the plug into the
connector on the loudspeaker.
Never connect the 4030B to the loudspeaker
outputs of a power amplifier or an integrated am-
plifier or receiver.
Once the connections have been made, the
loudspeakers are ready to be switched on.
