Positioning The Loudspeaker; Active Loudspeaker - Genelec 4030C Operating Manual

General
The bi-amplified Genelec 4030C is an extremely
compact two way active loudspeaker designed
for fixed installations. As an active loudspeaker, it
contains drivers, power amplifiers, active crossover
filters and protection circuitry. The 4030C 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
aluminium and shaped to reduce edge diffraction.
Combined with the advanced Directivity Control

excellent frequency balance in difficult acoustic
environments.

Positioning the loudspeaker

Each 4030C is supplied with an integrated amplifier
unit, mains cable, a 3-pin balanced Euroblock
connector for audio signal, 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 4030C 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. Audio input is via a 10 kOhm
balanced connector. The pin sequence of the

Connect the signal cable to the 3-pole plug
provided with the loudspeaker and secure the

loudspeakers, simply connect a second signal
cable to the plug and use it to route the signal to
the next loudspeaker (see Figure 4).
Never connect the 4030C 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
The automatic power saving function ISS (Intelligent
Signal Sensing) can be activated by setting the
"ISS" switch on the back panel to "ON." 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. 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
disabled by setting the "ISS" switch on the back
panel to "OFF." In this mode, the loudspeaker is
powered on and off using the power switch on the
back panel.
