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 60 – 80 Hz.

Subwoofer to CA51
The CA51 is a five channel amplifier. On channels
A/B, C/D the filter configuration is exactly the same
as for CA41. For speaker connections on these
channels you can use the examples for CA41.
Channel E is a subwoofer mono channel with a
lowpass filter adjustable from 50 to 500 Hz. Channel
E has also a subsonic filter that can be switched
IN-OUT. The subsonic filter has a fixed frequency
of 25 Hz.
You can connect one 4 ohm subwoofer to channel
E.

The subsonic filter takes away the very deepest
frequencies. Turn on the subsonic filter if you want
to remove these frequencis.

The LPF will allow low frequencies only and blocks
higher frequencies. A typical setting is 70 – 100 Hz.
higher frequencies. A typical setting is 70 – 100 Hz.
The phase control can be set continuously from 0 -
180 degrees. This is very useful when you want to
adjust the bass sound for best front stage image.
Start on 0 and turn the control slowly clockwise until
you experience the bass sound coming from the
front. If you dont get
the result you want,
also try to phase reverse
the subwoofer
connections and make
a new adjustment.
