Troubleshooting
Symptom
Solution
No sound
The connections to the ALF120 are very simple, so check for
a settings error or possible fault with the source or amplifier
before investigating connections at the ALF120.
Imbalance between
ALF120 and the
system speakers
If the bass sound from the ALF120 is not in balance with the
system speakers, check the subwoofer level settings in the
DSP configuration software. Ensure that the DSP placement
settings (corner, flat wall etc) have been correctly set.
Vibration (in-wall)
If the vibration occurs after completion of installation,
disconnect the system speakers and run only the ALF120 (or
just one ALF120 at a time where there are more than one).
Use a slow frequency sweep (from a PC signal generator
or test CD) to identify the problem frequency that excites
the vibration. Set this frequency to excite the vibration
continually, then locate the source by listening closely to the
vibrating area. The source may be a loose wire or pipe in a
cavity that should be tied down or foam wrapped, or a wall
fitted item such as a light.
If you cannot resolve the problem, contact your supplier.
