Genelec 4040A
Active Loudspeaker
General
Controls
The bi-amplified Genelec 4040A is a powerful but 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 4040A 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 Waveguide
TM
(DCW
), this design provides excellent frequency balance in difficult acoustic environments.

Positioning The Loudspeaker
Each 4040A 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 4040A
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 Phoenix connector. The connector also has two pins for 12
V trigger voltage for power switching. The
pin sequence of the connector is shown in
Figure 2.
Connect the signal cable and 12 V trigger
voltage to the 5-pole plug provided with the
loudspeaker and secure the connections by
tightening the screws on each pole. Push the
plug into the connector on the loudspeaker.
Never connect the 4040A to the loudspeaker outputs of a power amplifier or an
integrated amplifier or receiver.
Once the connections have been made,
the loudspeaker is ready to be switched on.
Level Control
The input sensitivity of the loudspeaker can
be matched to the output of the signal source
by adjusting the rotary level control on the
rear panel.
Autostart Sensitivity
This control sets the triggering sensitivity of
the signal sensing Autostart function. In case
of a high background noise level in the audio
network, the automatic shutoff may not function as the circuit detects the noise and misinterprets it as a valid signal. Switching the
“Autostart Sensitivity” switch to “ON” reduces
the triggering sensitivity and gives better
immunity to noise in the signal network. On
the other hand, if a very low playback level
is desirable, the Autostart function works
better in the more sensitive “OFF” setting.
The required triggering voltages are approximately 0.4 mV (OFF) and 1.4 mV (ON).
Autostart Off Time
This control sets the shutoff delay of the
Autostart function. When the switch is set to
“OFF”, the loudspeaker shuts off one hour
after ending the playback. In the “ON” setting,
the delay is 15 minutes.
Led Off
This switch turns off the green power indicator LED. However, the overload indication by
red coloured LED remains active.
Tone Controls
The frequency response of the Genelec
4040A can be adjusted to match the acoustic environment by setting the tone control
switches on the rear panel. The controls
are “Bass Roll-Off”, “Bass Tilt” and “Treble
Tilt”. An acoustic measuring system is recommended for analyzing the effects of the
adjustments, however, careful listening with
suitable test recordings can also lead to good
results if a test system is not available. Table
1 shows some examples of typical settings in
various situations. Figure 4 shows the effect
of the controls on the anechoic frequency
response.
Bass Roll-Off
The Bass Roll-Off control (switches 1 to 3
in switch group 1) affects the low frequency
roll-off of the loudspeaker and attenuates its

energy output near the cut-off frequency (55
Hz). Attenuation levels of -2, -4 or -6 dB can
be selected.
Bass Tilt
The Bass Tilt control (switches 2 to 4 in
switch group 2) offers three attenuation levels
for the bass response of the loudspeaker
below 800 Hz, usually necessary when the
loudspeaker is placed near a wall or other
room boundaries. The attenuation levels are
-2 dB (switch 3 “ON”), -4 dB (switch 4 “ON”)
and -6 dB (both switches “ON”).
Treble Tilt
The Treble Tilt control (switches 2 to 4 in
switch group 3) adjusts the treble response
of the loudspeaker at frequencies above 4
kHz. Two attenuation levels, -2 dB (switch 3
“ON”) or -4 dB (switch 2 “ON”) are available
for smoothening down an excessively bright
sounding system, while the +2 dB setting
(switch 4 “ON”) provides slightly increased
treble level suitable for heavily damped surroundings.
The factory setting for all tone controls is
“OFF” to give a flat anechoic frequency
response. Always start adjustment by setting all switches to “OFF” position. Measure
or listen systematically through the different
combinations of settings to find the best frequency balance.

Sufficient clearance for cooling of the amplifier and functioning of the reflex port must be
ensured if the loudspeaker is installed in a
restricted space such as a cabinet or integrated into a wall structure. The surroundings
of the loudspeaker must always be open to

of 5 centimeters (2”) behind, above and on
both sides of the loudspeaker. The space
Autostart And Remote Control
The 4040A is equipped with an Autostart
function, which automatically turns the ampli-
fier to Standby mode if an input signal has
not been detected for approximately 3 hours
(Auto Off Time switch set to “OFF”) or 15 min-
utes (Auto Off Time switch set to “ON”), and
back to “ON” mode when the signal returns.
Safety Considerations
Although the 4040A has been designed in
accordance with international safety standards, the following warnings and cautions
should be observed to ensure safe operation
and to maintain the loudspeaker under safe
operating conditions:
•Servicing and adjustment must only be
performed by qualified service personnel.
•The loudspeaker must not be opened.
•Do not use this product with an
unearthed mains cable or an unearthed
mains connection as this may compromise electrical safety.
•Do not expose the loudspeaker to water
or moisture. Do not place any objects
filled with liquid, such as vases on the
loudspeaker or near it.
•This loudspeaker is capable of producing sound pressure levels in excess of
85dB, which may cause permanent hearing damage.
•Free flow of air behind the loudspeaker
is necessary to maintain sufficient cooling. Do not obstruct airflow around the
loudspeaker.
•Note that the amplifier is not completely
disconnected from the AC mains service
unless the mains power cord is removed
from the amplifier or the mains outlet.
