We want a crossover point of 4 kHz between tweeter
and midrange. If you for some reason want to limit
the low bass reproduction switch on the HPF-filter.
The typical setting is then around 60 – 80 Hz. Switch
the LPF-filter switch to ON and the Multiply switch
to x10 position. Now you can adjust the filter setting
from 500 Hz to 5 kHz. Adjust the setting to 4 kHz.

Channel C/D are used for tweeters and must be
set to play from 4 kHz and up. The LPF-filter must
be OFF. The HPF-filter switchmust be ON and the
multiply swich in x 10 position. Now you can adjust
the filter setting from 150Hz to 5 kHz. Adjust the
setting to 4 kHz.

Two subwoofers connected in bridge mode
to CA40
NOTE!
4 ohm minimum load when using bridge mode
connection. Lower impedances may damage the
amplifier. In bridge mode the amplifier sees a 4
ohm load as 2 ohm.

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 should be in
ON-position. A typical setting is 70 – 100 Hz.
