Owner`s manual

Line inputs (7/8)

Please refer to Fig. 2 for connecting to low-level outputs on a receiver/amplifier (stereo mode). The two

channels are added to each other and are output by the subwoofer.

Please refer to Fig. 3 for connecting to an AV receiver with low-level subwoofer output. A second

subwoofer may be connected to the second input socket (8).

High-level inputs (9)

Please refer to Fig. 4 for connecting to the receiver's/amplifier's high-level (loudspeaker) outputs. The two

channels are added to each other and are output by the subwoofer.

Phase regulator (3)

In normal use the phase control should be set to 0°. However, in rare cases it may be advantageous to

vary the phase to between 0 and 180° (e.g. if the subwoofer is far away from the front satellites or in the

event of unfavourable acoustics in the room). Generally speaking: the setting where the lower base tone

area has a more natural sound is the correct one.

Level control (6)

This control is used to set the bass volume according to your preferences. Proceed as follows:

1. Set the bass control of your amplifier into its centre (linear) position.

2. Important: Set the level control to its left stop (lowest volume).

3. Now, play back some music and set the volume control of the amplifier to the desired level.

4. Set the subwoofer level control to the desired bass level.

Warning: when connecting to an AV receiver's subwoofer output, the subwoofer level should be set to

0 dB in the receiver's set-up.

Crossover frequency control (5), SUB/LFE switch (4)

1. Switch SUB/LFE switch to 'SUB': this option is selected when a normal (broadband) audio signal is

available as the input signal (e.g. stereo mode). The crossover frequency control is used to set the

subwoofer's maximum working frequency. The frequency should be set to 100 Hz – 150 Hz for shelf

speakers. The setting should be 50 Hz – 100 Hz for floor speakers.

2. Switch SUB/LFE switch to 'LFE': this option is selected when a low-pass filtered signal (LFE signal)

is available (e. g. connecting to the subwoofer output on an AV receiver). The internal filter will be

switched off, the crossover frequency control will have no effect. Here, the crossover frequency

between the subwoofer and surround loudspeakers must be set on theAV receiver. Please also refer

to the AV receiver's operating instructions.

Fuse (12)

Only use a fuse with the parameters indicated next to the fuse holder on the rear of the amplifier.
