Page 14: Setting The Satellite Cut-Off Frequency (Sat Highpass)
Setting the cut-off frequency Switch SAT Highpass control to needed position. Depending on the bass capabilities of the speakers, the fre- quency range of subwoofer and speakers can overlap be- tween 50 Hz and 150 Hz. A bump or a gap in the frequency Dynaudio Acoustics BM9S response and thus a lower sound quality will be experienced if the system is not matched properly. In addition, small speak- ers and low powered amplifiers will particularly be affected by the low frequency signals, which again has a negative effect on the sound quality. Therefore it makes sense to limit the bass range of the connected speakers (called “satellites” in... -
