9. Subwoofer with integrated Crossover
When using subwoofers with integrated crossover on the CD 44, set the XO switch on the
connecting terminal of the subwoofer to XO ’OFF’.
We do not recommend the passive use of a subwoofer at a top speaker (XO ‘ON’) on the
CD 44.
10. SP Speakers
The line inputs of the SP speakers are only connected with the desired outputs of the
controller (Out 1 through Out 4). Connecting the amplified signal to the connector AMP
RETURN / SENSE of the CD 44 is not possible with an SP speaker. This is not necessary,
though, because the SP speaker is equipped with its own limiters guaranteeing the operating
safety.
If you do not wish to use the limiter in the CD 44, set up the AmpGain as followed: <Out »
Output 1> through <Output 4 » AmpGain » Gain/dB>: +20.0 (lowest possible value).
If you also wish to use the limiter in the CD 44, i.e. for level limiting, then you must set the
AmpGain to +30.0. With this setting, you can select the desired level limit at <Out » Output
1> through <Output 4 » LimitReduction>.
You can use the SP speakers in two different ways on the CD 44:
1. With the LS-Block 'Flat':
With this, the overlap filter characteristic of the SP speaker is maintained. In this case,
move the switch 'FILTERS' in the connecting panel of the SP speaker to 'ON' and the Gain
potentiometer to 0 dB.
2. With the LS-Block of the respective K&F speaker system:
With this, you can use the filter characteristic for the passive speaker. In this case, select
the LS-Block which goes with your SP speaker. For example, select the LS-Block CA 1201
LCut for 2-way operations of the speaker CA 1201-SP, or the CA 1201 FR for full-range
use. Move the switch 'FILTERS' in the connecting panel of the SP speaker to 'OFF' and
turn the Gain potentiometer on the connecting panel of the SP speaker to 0 dB.
