Finishing
Testing the ALF100SM
The ALF100SM should be fully tested
again at this stage, preferably as a
system with any speakers, before
decorating the wall.
CAUTION: The ALF100SM must
only be tested with DSP
protection applied by using a DSP
equipped amplifier, or a non-DSP
amplifier with an external Digital
Signal Processor. Refer to the
‘Planning and Installation’ section
for more details.
Using an amplifier with no
protection may permanently
damage the ALF100SM.
• Connect the amplifier to the cable
from the ALF100SM.
• Disconnect any other system
speakers.
• Play a signal with high bass content.
A low frequency sweep is also a useful
test signal at this stage.
• Increase the volume level and listen
carefully for vibration or other noises.
• If you hear any vibration or noises
locate the source of these and rectify
the problem.
• Connect up the system in-wall or
free-standing speakers.
• Test the complete system to confirm
that the sound from the subwoofer
integrates well with the other
speakers.
