WARNING The unit uses dangerous mains voltage. Leave servicing to skilled personnel only. Inexpert handling or modification of the unit may result in electric shock.

The unit is suitable for indoor use only. Protect it against dripping water and splash water, high air humidity and heat (admissible ambi- ent temperature range 0 – 40 °C).

Do not place any vessel filled with liquid on the unit, e. g. a drinking glass.

The heat generated inside the unit must be dissipated by air circulation. Do not cover the air vent (bass-reflex opening).

Do not operate the unit or immediately dis- connect the mains plug from the socket

if the unit or the mains cable is visibly dam- aged,

2. if a defect might have occurred after the

unit was dropped or suffered a similar accident,

3. if malfunctions occur.

In any case the unit must be repaired by skilled personnel.

Never pull the mains cable to disconnect the mains plug from the socket, always seize the plug.

For cleaning only use a dry, soft cloth; never use water or chemicals.

No guarantee claims for the unit and no liabil- ity for any resulting personal damage or mate- rial damage will be accepted if the unit is used for other purposes than originally intended, if it is not correctly connected or operated, or if it is not repaired in an expert way. If the unit is to be put out of operation definitively, take it to a local recycling plant for a disposal which is not harm- ful to the environment. 3 Applications This compact active subwoofer is used as a low-frequency complement of existing audio systems for hi-fi applications, home cinema and home recording applications. It is equipped with a 20 cm (8”) bass speaker. Its amplifier offers a peak output power of 90 W. The subwoofer features an adjustable low pass filter, a volume control, a phase reversal switch and an automatic standby mode. Two stereo inputs are available (each with a feed-through output): one input for connection to an output with line level and one input for connection to a speaker output. 4 Setting Up and Connecting Set up the subwoofer on a flat surface. It is not important to place the subwoofer exactly in the middle between the stereo speakers as it will not be possible to precisely locate the very low frequencies reproduced by the subwoofer. However, do not place it too close to walls or in corners; this would distort the frequency re- sponse and prevent the heat dissipation of the integrated amplifier. Likewise, do not cover the bass reflex opening on the rear side. Prior to making or changing any connec- tions, switch off the subwoofer and the units to be connected. Connect a signal source via one of the two connection options described in chapters 4.1 and 4.2.

4.1 Stereo input LINE IN

If a stereo output with line level is provided (e. g. output of a preamplifier or mixer), connect this output to the input LINE IN (7) on the subwoofer. From the two stereo channels, a mono signal will be created internally for the subwoofer. If the outputs of the preamplifier or mixer are already used for the existing audio system, use an adapter to divide the output signal (e. g. ACA-120 from MONACOR). As an alternative, the feed-through output LINE OUT (8) can be used to divide the output signal: Feed the output signal of the preamplifier/mixer to the input LINE IN (7) and then, via the output LINE OUT, route it to the audio system.10 English

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.

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.

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.11 English

Reproduce sound, e. g. music, via the existing audio system and add the desired low bass part with the VOLUME control (2). Only turn up the control to such an extent that the sound reproduced will not be distorted.

Use the control CROSSOVER (3) to adjust the cutoff frequency of the low pass filter so that the subwoofer will optimally complement the frequency re sponse of the other speakers. If required, readjust the volume balance with the VOLUME control (2).

Different distances of speakers to the listener may result in phase cancelation (certain fre- quencies will have a lower volume). To com- pensate this, the phase of the subwoofer signal is reversible with the PHASE reversal switch (9). Test both switch positions to find the position offering the bass reproduction of the highest volume at the listening position. Then readjust the volume balance with the VOLUME control (2), if required.

If the automatic standby mode is deactivated
