Selecting Phase:
Generally, 180° is the appropriate setting in 60-70% of all cases,
depending on the main speakers employed. If you have not achieved a satisfactory result
with the Volume and Crossover Frequency controls, try switching Phase to 0° before
adjusting Volume and Crossover Frequency again (fig. 7).
Once the subwoofer is fully integrated with your main speakers, the subwoofer should be
broken in over several days with a wide range of music or movies. After this period, you
may wish to adjust Volume, Crossover Frequency and, possibly, Phase again. You should
be aware that the ideal settings for two-channel music may not be ideal for multi-channel
surround. Make a note of the differences, if you choose to optimise your system each time
you change from stereo to surround.
Auto Shut Off places the subwoofer in standby after approximately 15 minutes without a
signal. The subwoofer turns on automatically when a signal is present.
Power should only be used to turn off the subwoofer when it will not be used for an
extended period or before changing any connections.
OVERLOAD
Placing the subwoofer close to a wall will increase bass output, without increasing the
load on the subwoofer. This allows increased bass levels without distortion. If the resulting
sound and placement is acceptable, this is a convenient means of increasing bass output.
Although the subwoofer is protected against minor, brief overload situations, pay careful
attention in the event of mechanical or electrical noise or distortion. At the very first sign of
overload, immediately turn down Volume on the subwoofer. If this occurs frequently, you
should permanently select a lower Volume setting. See section on SET-UP.
BREAK-IN PERIOD
A loudspeaker is a mechanical device and as such requires an extended initial period of
normal use during which you will notice a gradual improvement in sound quality.
Wear is not a problem with DALI loudspeakers, regular use will only extend their life.
