With the HPF-filter in OFF position the amplifier
allows the speakers to play fullrange. If you for
some reason want to limit the low bass
reproduction switch on the HPF-filter. The typical
setting is then around 25 – 40 Hz.
The LPF-filter should be OFF.

The HPF filter is here used as subsonic filter to take
away the very deepest frequencies. The typical set-
ting is around 25 – 40 Hz.

The LPF will allow low frequencies only and blocks
higher frequencies. A typical setting is 70 – 90 Hz.
In the CA23 amplifier you can select
between two
different slopes, 12 dB/ octave or 24 dB/ octave.
Choose the slope and the setting that sounds best
in your car.
