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
Please use a soft, dry cloth with no cleaning agents, sprays or chemical solvents, as these could
damage the surfaces.
