XLf 8A
A few important notes:
By turning the control clockwise, the input sensitivity of the
ampli er and, therefore, also the volume increases. However,
this is not a volume control; no further amplif ier output
can be achieved in the end position, even if it may sound
like that at the beginning. The system merely increases the
volume faster if the volume control of the car sound system
is turned up.
CROSSOVER frequency control
The CROSSOVER control allows setting the desired exit
frequency band in this base, 20 Hz - 80 Hz is the ideal
Example:
At a setting of 150 Hz, the has a frequency range ampli er
of 20 Hz to 150 Hz. We suggest a setting of 80 Hz.
Settings
The following control setting is recommended as basic
setting before putting the device into operation: Sensitiv-
ity (GAIN) Pos. to minimum, PHASE Pos. to 0°, x-over
Pos. to approx. 80 Hz. Switch on the device and select a
musical piece with distinctive bass playback.
Increase the volume of your car sound system to the desired
volume level. Now slowly increase the VOL control until
you can hear a clear
of the bass level. Next, ampli cation
use the CROSSOVER control to select a setting that lter
provides a well-contoured bass. You may have to alternately
optimise the sensitivity setting and the
. lter setting

The phase switch must be set so that the bass is inte-
grated into the acoustic pattern as best as possible and not
recognisable as an individual source.
Also check your settings of the XLf 8A with the bass con-
trol fully open and, if necessary, with activated loudness. An
overloading of the subwoofer box by selecting an excessive
ampli cation Pos. results in a distorted playback and can
damage the loudspeaker.
