tening position is dependent upon the posi-
tion of the subwoofer.
Two phase matching switches in the
crossover allow compensation for incorrect
phasealignment.Foursettingsareprovided
between0°and-270°.
Coarse phase correction
method
• Conguretheprocessorsothatthemain
speakers(L,C,R)aresetto“small”and
check the main speaker/subwoofer
crossover frequency setting on your
processor. This frequency may be
variableorxed:consulttheoperating
manual of your processor.
• Connectanaudiosignal
generator to one of the input channels
used in the system.
• Setthesignalgeneratortothesame
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.
• Togglethe-180°phase
switch(#4)"ON"and"OFF"
and set it to the position
which gives the lowest sound
level at the listening position.
• Nexttogglethe-90°phase
switch(#3)"ON"and"OFF",
and again set it to the
position which gives the
lowest sound level.
• Finally,setthe-180°phase
switch to the opposite setting.
After the phase setting has been completed,

Using multiple subwoofers
The5041Aisequippedwitha“LINKOUT”
connector to provide an easy way of cou-
pling two or more subwoofers together in
high SPL applications. Connect an XLR
cablefromthe“LINKOUT”connectorofthe
master subwoofer to which the decoder is
connected,tothe"XLRIN”inputconnec-
tor of the other, slave subwoofer. When
two subwoofers connected in this way
are positioned close to one another, bass
levelincreasesby6dB.Threesubwoofers
givea bassSPLincrease of9,5dB and
foursubwoofersprovidea12dBincrease
compared to a single subwoofer. Adjust the
sensitivity control of all subwoofers in the
grouptomatchtheSPLlevelofthemain
loudspeaker system. Note that the sensitiv-
ity setting must be the same on all subwoof-
ers.
Autostart and Remote
ControlFunction
The 5041A is equipped with an“AUTO-
START” function, which automatically
turnstheamplierto“STANDBY”modeif

Theampliermodecanalsobeswitched
by a 12Vtrigger type remote control unit
connected to the respective inputs on the
amplier(see"SubwooferCabling").Switch
the“REMOTECONTROL”dipswitchto“ON”
to activate this function. Remote control over-
ridesthe“AUTOSTART”function.
AutomaticProtectionCircuits
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.
