Blaupunkt 7 644 820 310 operating instructions Setting up the centre speaker

To avoid interference due to extremely low frequencies, you can set the sub- sonic filter to limit the frequency re- sponse of the device at the lower end of the range. This makes particularly good sense if you are using a small sub- woofer. If you set up the subsonic filter, all the frequencies below the set fre- quency will be suppressed. When set- ting up the subsonic filter, you should base the settings that you choose on the specifications of the loudspeakers in your vehicle.
