The CA41 is a four channel amplifier. It is mostly

used with a front system connected to channels C/

D and a subwoofer connected to channel A/B. You

will find speaker wiring and filter setting example on

page 10. Please observe the proper settings of the

channel A/B LPF multiplier switch and of the channel

C/D HPF multiplier switch.

The CA41 can also be used to feed a 2–way front

system with active crossovers between midbasses

and tweeters. This is described in a speaker wiring

and filter setting example on page 11.

Channel A/B is equipped very much like the CA22

and CA23, however the LPF has a multiplier. Thus

the frequency range of the LPF can be varied from

50 Hz – 500 Hz in the x1 position or 500 Hz – 5 kHz

in the x10 position. This way we can use this

amplifier to feed a 2-way system, where the

midbasses are feed from 80 Hz – 4 kHz.

The tweeters connected to channel C/D , operate

from 4 kHz upwards using the HPF in multiplier po-

sition x 10 150 Hz – 5 kHz.

The CA51 is a five channel amplifier. On channel

A/B, C/D the filter configuration is exactly the same

as for CA41.

Channel E is a subwoofer mono channel with a

lowpass filter adjustable from 60 to 120 Hz. Channel

E has also a subsonic filter that can be switched IN-

OUT. The subsonic filter has a fixed frequency of

25 Hz. The CA51 has also a phase control variable

from 0 - 180 degrees.

The CA31 is a three channel amplifier. It has a

variable high pass filter, 50-150 Hz, for channel A/

B. The C channel is for subwoofers and has a

subsonic filter, a variable low pass filter, 50-120 Hz,

and a phase control variable from 0 - 180 degrees.

The subsonic filter can be switched IN-OUT and has

a fixed frequency of 25 Hz.
