4.2 Stereo input HIGH LEVEL IN
If no output with line level is available, connect
the input HIGH LEVEL IN (11) to the speaker out-
put of the amplifier (LEFT = left channel, RIGHT
= right channel) . Observe the correct polarity
of the connections . When connecting, always
switch off the amplifier . Make sure that the cable
ends used for connection to the screw terminals
are only stripped as far as necessary and that no
bare wires stick out (danger of contact and short
circuit) . The output jacks HIGH LEVEL OUT (12)
are directly connected to the corresponding jacks
HIGH LEVEL IN . Use these jacks to connect the
other speaker systems .
There are banana jacks under the protective
caps of the screw terminals .
WARNING If an amplifier is connected to the
inputs HIGH LEVEL IN (11), cover
all banana jacks not used with
the protective caps; touching the
connections may result in electric
shock .
4.3 Power supply
Use the mains cable provided to connect the
mains jack (5) to a mains socket (230 V/ 50 Hz) .

5 Operation
CAUTION Never adjust the audio system to
a very high volume . Permanent
high volumes may damage your
hearing! Your ear will get accus-
tomed to high volumes which do
not seem to be that high after
some time . Therefore, do not fur-
ther increase a high volume after
getting used to it .
Note: To prevent switching noise, always switch on the
units connected before switching on the subwoofer and
switch it off first after use .
1) Set the VOLUME control (2) to MIN (left
stop) for the time being and switch on the
subwoofer with the POWER switch (4) . The
LED (1) will light up .
2) Use the switch (10) to switch the automatic
standby mode on and off .
Position "AUTO":
The automatic standby mode is activated .
The subwoofer will automatically be in oper-
ation once an input signal has been applied .
The LED (1) will show green . If the signal
level falls below a certain value for a few
minutes, the subwoofer will return to the
standby mode; the LED will show red .
Position "ON":
The automatic standby mode is deactivated .
After switching on, the subwoofer will
always be in operation . The LED (1) will show
green .
Position "OFF":
The subwoofer is always in standby mode .
The LED (1) will show red . Thus, it will be
possible to set the subwoofer to the standby
mode immediately, e . g . for testing the
switch-on threshold in the position "AUTO"
subsequently .
