Installation
Testing the ALF100SM
At this point the ALF100SM should be
fully tested.
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.
• If already installed, disconnect any
other system speakers.
• Play a signal with high bass content.
A low frequency sweep test signal is
also useful 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.
• If speakers are installed, connect
them up.
• Test the complete system to confirm
that the sound from the subwoofer
integrates well with the other
speakers.
Any vibration or other noises found
during test should be investigated
and cured before continuing with
installation.
Please note: The ALF100SM is
fitted with 2mm x 20mm (
1
/
8
” x
3
/

”) closed cell foam tape around
the rear flange contact surface to
avoid contact vibrations.
