9.1
Operating the Systems without K&F System Controller
The full-range systems can be used alone or in conjunction with a K&F subwoofer with
integrated crossover (e.g. SW 112-XO / SW 115D-XO SW 115E-XO or SW 118E-XO). In
this mode of operation the crossover limits the subwoofer's frequency range.
To protect the speakers from being destroyed and to avoid fire hazard, they should
only be operated with professional power amplifiers with the following specifica-
tions:
−
integrated or preceding subsonic filter (approx. 30 Hz, min. 12 dB / octave)
−
integrated clipping limiter
−
for speaker model CA 1201 or CA 1215:
maximum rated power 500W@8
Ω
(equivalent 1000W@4
Ω
)
−
for speaker model CA 1515:
maximum rated power 700W@8
Ω
(equivalent 1400W@4
Ω
)
If you wish to use a speaker with a power amplifier which does not fulfil these spec-
ifications, then the speaker should be controlled using a Kling & Freitag System
Controller with limiter function. This is the only way overloading and the risk of fire
can be avoided. The results of such a power amplifier defect cannot be avoided by
the controller.
9.1.1
CA Systems in Full-Range Mode
This mode of operation is ideal for speech applications and music applications without
the need for a high bass content. Should more bass be needed, the bass level can be
increased between 50 and 80 Hz at the mixing console.

If you are operating a mid-high system in a cluster (speakers arranged in close proximity)
or as a stage monitor, reduce the frequencies below 300 Hz by 3-4 dB! (The K&F Sys-
tem Controllers have a special ‘Top Low Cut’ filter function for this purpose.)
