Mounting Considerations
Align The Loudspeakers Correctly
Always place the loudspeakers so that their
acoustic axes (see Figure 1) are aimed
towards the center of the listening area.
Only vertical placement is preferred, as it
minimises acoustical cancellation problems
around the crossover frequency.
Minimise Reflections
Acoustic reflections from objects close to the
loudspeakers like walls, cabinets etc. can
cause unwanted colouration or blurring of
the sound image. These can be minimised
by placing the loudspeaker clear of reflective
surfaces.
Minimum Clearances
Sufficient clearance for cooling of the ampli-
fier and functioning of the reflex port must be
ensured if the loudspeaker is installed in a
restricted space such as a cabinet or inte-
grated into a wall structure. The surroundings
of the loudspeaker must always be open to
the listening room with a minimum clearance
of 5 centimeters (2”) behind, above and on
both sides of the loudspeaker. The space
adjacent to the amplifier (back panel of the
enclosure) must either be ventilated or suf-
ficiently large to dissipate heat so that the
ambient temperature does not rise above 35
degrees Celsius (95°F).
Mounting Options
The Genelec 4040A offers several mount-
ing options: It can be fitted to Omnimount®
Series 30 and König & Meyer loudspeaker
mounts or the keyhole wall mount adapter
provided with the loudspeaker on two sets
of M6x10 mm threaded holes on the back of
the enclosure. On the base of the enclosure
is an M10x10 mm threaded hole which can
be used for securing the loudspeaker to its
base. See Genelec Accessories Catalogue
on www.genelec.com for a complete list of
mounting hardware options.
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.
The triggering sensitivity can be selected
with the Autostart Sensitivity switch (see
chapter Autostart Sensitivity above).
The amplifier mode can also be switched
by a 12 V DC trigger type remote control. The
remote control wires can be connected to the
first two (starting from left) poles of the Phoe-
nix connector (See Figure 2 for the connector
pin sequence). Remote control overrides the
Autostart function.
Maintenance
No user serviceable parts are to be found
within the loudspeaker. Any maintenance
or repair of the 4040A unit should only be
undertaken by qualified service personnel.
Safety Considerations
Although the 4040A has been designed in
accordance with international safety stand-
ards, 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 compro-
mise 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 produc-
ing sound pressure levels in excess of
85dB, which may cause permanent hear-
ing damage.
•
Free flow of air behind the loudspeaker
is necessary to maintain sufficient cool-
ing. 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.
