Setup notes
Note
Our website contains comprehensive notes for correct setup.
• Select a stable, level base.
• Make sure that the environment is clean and free from dust.
• Avoid placing the unit close to sources of heat or in direct
sunlight.
• Arrange the connector cables so that they do not pose a trip
hazard.
• Do not place any heavy objects on the cables or the speaker.
• The location of the subwoofer can be freely selected and
does not influence the other speakers. However, do not place
it in the corner of the room as this may result in irregular
frequency overloads. A location between the front speakers
is often ideal.
• Make sure that the speaker has a stable position to prevent
vibrations.

Connecting the signal cable
Danger Danger of injury/damage!
Arrange the cables so that they do not pose a
trip hazard.
• Disconnect the power plug for the device to be connected
from the power outlet.
• Ideally, the subwoofer is connected to the subwoofer output
of the AV receiver or preamplifier (DecoderStation/Control-
Station) or Soundbar using a mono RCA cable.
• The RCA jack 2 “Line In” on the back side of the subwoofer is
intended for this purpose.
• You can find additional information in the operating instruc-
tions of the receiver, Soundbar or DecoderStation/Control-
Station.
• If your receiver doesn’t feature a subwoofer connection,
connect an available speaker output to the RCA jack 2of
your subwoofer using a voltage reducer and a RCA connector
cable. We offer voltage reducers on our website in the “Ac-
cessories” area.
Connection to the grid
• Ensure that the mains switch 6“Power” on the subwoofer is
switched off (“0 OFF” position).
• Connect the power plugs of the subwoofer and the connect-
ed device to a power outlet.

Use
Activating and deactivating
• The subwoofer is activated or deactivated with the switch 6
“Power”. If the subwoofer is on, the control LED 4is illumi-
nated.
Automatic activation/deactivation
• Switch 3 “On/Auto”:
–Auto position: The subwoofer activates as soon as an
audio signal is present on jack 2 “Line In” (control LED 4is
illuminated in green).
If there's no audio signal for 10 minutes, the subwoofer
switches to standby (control LED 4is illuminated in red).
–On position: The subwoofer is continually activated.
Volume
• You can control the volume of your subwoofer using the
volume control 1“Volume”.
Phase
• Switch 5“Phase” is used to activate and deactivate phase
shifting (180°) for the subwoofer. Choose a setting at which
the subwoofer emits the loudest and most precise sound.
Crossover frequency
• The subwoofer must be “On” in the AV receiver's bass
management/speaker management (“Speaker Setup”). The
appropriate crossover frequency to be set there depends on
the satellites being used. You can find specifications for the
crossover frequency of the respective satellites in the techni-
cal data section of our web shop.
• The crossover frequency is adjusted automatically in case of
using a Soundbar.
• Notes on setting up the crossover frequency for the Decoder-
Station 5 Mk2 can be found in the corresponding operating
instructions.
