Only put the device into operation when you have become familiar with its features and these
operating instructions. Check again that all connections are correct. Do not put the product into
operation if it is damaged.
The subwoofer should always be the last to be turned on and the
first
to be turned off. This way
you can prevent any undesired noise (which typically occurs when switching off a mixer) that may
damage the subwoofer.
Ensure that the subwoofer is not overloaded. Playback must never be distorted. If distorted music
signals can be heard although the volume was not set too high, switch off the subwoofer immedi-
ately and check the connection. If the connection is correct, please contact a specialist.
The device must only be operated by persons familiar with the operating instructions and obser-
ving them. Keep other persons and children away from the device.
•
Turn the controller SUB LEVEL (1) all the way back (to the left stop).
•
Put the SUB CROSSOVER (6) controller roughly to the middle position.
• Switch
on
the connected mixer and start playback. Set
a
medium volume at the mixer.
• Turn
on
the subwoofer with the
POWER
switch (9).
• The display SIGNAL
OK
(4)
lights up if
an
input signal is pending at the LINE IN
(2)
connection.
• Set the mixer volume to approx.
75%
of the maximum volume or the maximum undistorted level (visible for devices
with level indicator at the „0 dB mark).
•
Now adjust the subwoofer volume to the maximum required volume with the controller SUB LEVEL (1) and adjust
the volume of the subwoofer and satellite speakers.
This setting achieves the highest possible signal-to-noise ratio and enables the best audio quality. Note that the
maximum volume depends of the entire audio system depends
on
the performance of the connected speakers and
the installed amplifier. If the volume is too high, this may lead to damage to the satellite speakers as well as the
subwoofer.
If the display PEAK/LIMIT
(3)
lights up, the subwoofer volume is set too high and must be reduced.
•
Set the crossover frequency of the subwoofer with the controller SUB CROSSOVER (6). The subwoofer should
supplement the satellite speakers in the low-bass area and should not drone.
• After this basic setting, the overall volume of the audio system is
only
set with the mixer volume controller. Every
change of the wirings requires repetition of the setting process.
• Try switching the switch PHASE (7). Depending
on
site of setup of the satellite speakers, the phase inversion of the
subwoofer caused
by
this switch
may
improve
bass
playback. The position where the
bass
is cleaner and louder is
correct.
•
To switch the system off, first switch off the subwoofer with the POWER switch (9) and then switch off the mixer.
