Depending on the bass capabilities of the speakers, the frequency range of subwoofer and speakers can overlap
between 50Hz and 150Hz. A bump or a gap in the frequency response will result in lower sound quality. In
addition, small speakers and low powered amplifiers are particularly stressed by low frequency signals, which
again has a negative effect on the sound quality. It is useful therefore to limit the bass range of the connected
speakers (called “satellites” in this case) through a high-pass filter. The 9S provides two high-pass filter settings to
achieve this:
▪
Flat = no filter
▪
60Hz = frequencies below 60Hz are filtered.
▪
80Hz = frequencies below 80Hz are filtered.
To set the filter frequency
Switch the High-pass control to the required position.
