Setting the low-pass fi lter

"40 Hz", "50 Hz", "63 Hz" and "100 Hz". If
your subwoofer features a built-in low-pass
fi lter, you can also select the setting "FLAT"

Setting the subsonic fi lter
To avoid interferences from extremely low
frequencies, you can use the subsonic fi lter
to limit the low-frequency response of the
device. This is particularly useful for small
subwoofers. The setting of the subsonic fi l-
ter suppresses all frequencies below the de-
fi ned frequency. When setting the subsonic
fi lter, you should orient yourself by means
of the loudspeaker setup of your vehicle.
You can select from the frequencies "20 Hz",
"25 Hz", "32 Hz" and "40 Hz". In addi-
tion, you can set the quality factor "Q" for
the selected frequency in fi ve increments:
"Q1"=0.5, "Q2"=0.7, "Q3"=0.9, "Q4"=1.1
and "Q5"=1.3.
If you select the setting "FLAT", the frequen-
cy response of the device is not affected.
