Connecting power supply
The switch "Power" is the on/off switch for the
subwoofer. Normal position is ON which makes the
subwoofer start with the rest of your system,
POWER LED glows green. After a period without
input signal the amplifier atomatically reverts to
standby, POWER LED glows red. The OFF posi-
tion is used when the subwoofer should not be
used for some time.
Tuning the system
Running-in period
The performance of the subwoofer will change
subtly during the listening period. Please allow
your new subwoofer to play about 50 hours of
music at normal listening level before doing any
critical listening.
Placement
The bass reproduction in a room is the result from
many factors. The performance of the subwoofer,
the dimensions of the room and the placement of
the subwoofer. The most important factor is
probably where in the room the subwoofer is
placed. The character will change as you move the
subwoofer around, small changes in positions -
20cm can have a significant effect on the sound.
We recommend that you try out what give maxi-
mum performance in your room; by a wall, in a
corner or a free-standing position.
