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.
Cross-over frequency control (7)
Used to set the upper limit of the subwoofer operating range. The cross-over frequency should be set to
approxi-mately 100 to 150 Hz when the system is used in combination with shelf loudspeakers and to
50 to 100 Hz with stand loudspeakers.
Phase switch (8)
In normal use the phase switch should be set to 0°. However, in rare cases it may be advantageous to set
the phase to 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 fuller sound
is the correct one.
Fuse (9)
Only use a fuse with the parameters indicated next to the fuse holder on the rear of the amplifier.
MAINTENANCE
The lacquered surface is best cleaned with a mild household cleaner. On no account use furniture polish
or similar products on these surfaces. Please also do not use a microfiber cloth as this may damage the
surface.
