<p>Audio systems are known and are used to reproduce audio signals from for example prerecorded CDs or to reproduce received radio signals. To improve the signals especially in the lower frequency range so called ultra bass is known. The invention proposes to further improve the signals in the low frequency range by introducing a feed forward control to overcome problems with supplying signals in the low frequency range with a volume that would overdrive the loudspeakers.</p> |
