tening position is dependent upon the posi-
tion of the subwoofer.
Two phase matching switches in the
crossover allow compensation for incorrect
phase alignment. Four settings are provided
between 0° and -270°.
Coarse phase correction
method
• Configure the processor so that the main
speakers (L, C, R) are set to “small” and
check the main speaker/subwoofer
crossover frequency setting on your
processor. This frequency may be
variable or fixed: consult the operating
manual of your processor.
• Connect an audio signal
generator to one of the input channels
used in the system.
• Set the signal generator to the same
frequency as the subwoofer crossover
frequency on your decoder. If a signal
generator is not available, you can use an
audio test recording with a suitable range
of test frequencies.
• Toggle the -180° phase
switch (#4)"ON" and "OFF"
and set it to the position
which gives the lowest sound
level at the listening position.
• Next toggle the -90°phase
switch (#3) "ON" and "OFF",
and again set it to the
position which gives the
lowest sound level.
• Finally, set the -180°phase
switch to the opposite setting.
After the phase setting has been completed,
return the speaker configuration on the proc-
essor to its’ original settings.
Using multiple subwoofers
The 5041A is equipped with a “LINK OUT”
connector to provide an easy way of cou-
pling two or more subwoofers together in
high SPL applications. Connect an XLR
cable from the “LINK OUT” connector of the
master subwoofer to which the decoder is
connected, to the "XLR IN” input connec-
tor of the other, slave subwoofer. When
two subwoofers connected in this way
are positioned close to one another, bass
level increases by 6 dB. Three subwoofers
give a bass SPL increase of 9,5 dB and
four subwoofers provide a 12 dB increase
compared to a single subwoofer. Adjust the
sensitivity control of all subwoofers in the
group to match the SPL level of the main
loudspeaker system. Note that the sensitiv-
ity setting must be the same on all subwoof-
ers.
Autostart and Remote
Control Function
The 5041A is equipped with an “AUTO-
START” function, which automatically
turns the amplifier to “STANDBY” mode if
an input signal has not been detected for
approximately 30 minutes, and back to “ON”
mode when the signal returns. The function
can be deactivated by turning the “AUTO-
START” dip switch to “OFF”. A two-colour
LED on the amplifier panel indicates the
amplifier status: green for “ON” and yellow
for “STANDBY”.
The amplifier mode can also be switched
by a 12 V trigger type remote control unit
connected to the respective inputs on the
amplifier (see "Subwoofer Cabling"). Switch
the “REMOTE CONTROL” dip switch to “ON”
to activate this function. Remote control over-
rides the “AUTOSTART” function.
Automatic Protection Circuits
The 5041A is equipped with protection cir-
cuits against bass driver thermal overload
and amplifier overheating. The protection
system resets automatically so that the user
only has to turn the input level down to ensure
that it does not reactivate.
Safety considerations
The Genelec 5041A complies with interna-
tional safety standards. However, to ensure
safe operation and maintain the equipment in
safe operating condition the following warn-
ings and cautions must be observed.
• Servicing and adjustment must only be
performed by qualified service personnel.
• Opening the amplifier is strictly
prohibited except by qualified service
personnel.
• Do not expose the subwoofer or amplifier
to water or moisture. Do not place any
objects filled with liquid, such as vases on
or near them.
• Always use a mains power cable and
connection with protective earth. Failing
to do this may lead to personal injury.
• Note that the amplifier is not completely
disconnected from the AC mains service
unless the mains cable is removed from
the amplifier or the mains outlet.
Warning!
This equipment is capable of delivering sound
pressure levels in excess of 85 dB, which
may cause permanent hearing damage.
Maintenance
There are no user serviceable parts inside
the amplifier or subwoofer enclosure. Any
maintenance of the unit must only be per-
formed by qualified service personnel.
Guarantee
This product is supplied with two year guaran-
tee against manufacturing faults or defects that
might alter the performance of the unit. Refer
