Q Power function
OFF means that the subwoofer is switched off; ON
means that it is switched on. AUTO means that the
subwoofer is operational but is only activated once
it receives an audio signal. In "AUTO" mode, the sub-
woofer automatically switches to standby after 20
minutes of inactivity.
W Line Input
Connect the AV receiver's "Sub Out" to the subwoof-
er's "Line Input" using a mono RCA cable (optionally
with an additional Y adapter).
E Line Output
Here, you can connect a second subwoofer for added
bass or to compensate for resonant frequencies in
the room.
R Low Pass – Full Range
With the switch on "LOW PASS" , the built-in con-
trols for "Phase" and "Frequency" are activated.
With the switch on "FULL RANGE" (recommended
setting), these parameters are controlled by the
AV receiver.
T Level
Use the "LEVEL" control to adjust the subwoof-
er's volume. In the receiver's bass management
section, set the bass level to a high value, i.e.,
between 6 and 12 dB. Next, set the subwoofer's
level control to 10 o'clock. While the AV receiver
is outputting its white noise setup signal, slowly
W
turn up the subwoofer level to the desired vol-
E
ume.
T
O
Y Phase
This switch determines the phase relationship be-
Q
U
tween the subwoofer and the front/centre speakers.
If the subwoofer is positioned in the speaker setup
Y
R
as indicated on p. 9 (grey area of drawing), set the
phase to 0°. With other setups, the 180° setting may
produce better results.
U Frequency
Use this control to set the crossover fre-
quency between the subwoofer's bass signal
and the bass frequencies of the other speak-
ers. If you are using an AV receiver, set the re-
ceiver's crossover frequency to 100 Hz and turn
the subwoofer's frequency control to maximum
(hard right).
I Power
OFF means that the subwoofer is switched off; ON
means that it is switched on.
O Power LED
When the subwoofer's mains power switch I is
off, the power LED is off. When the subwoofer's
mains power switch I is on, the power LED lights
up red or green, depending on the position of the
Power Function switch Q.
When the subwoofer is permanently active
(= Power Function Q ON), the power LED is green.
When the subwoofer is in standby mode (Power
Function Q AUTO), the power LED is red. After
the subwoofer is triggered into activity, the LED
changes to green. After the subwoofer switches
itself off after 20 minutes of inactivity, the LED is
red again. When the Power Function switch Q is
on OFF, the LED is red.
P Voltage selector
This switch adapts the internal amplifier to the
local mains voltage. NEVER set this to any other
value than the standard local voltage value. In
Germany, the correct position is "220 – 240V" .
