9.1 Operating the Systems without C2 Controller
The CA 106 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.
ƒ
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. 20 Hz, min. 12 dB / octave)
− integrated clipping limiter
− maximum rated power 250W@16 Ohms (equivalent 1000W@4 Ohms)
ƒ If you wish to use a speaker with a power amplifier which does not fulfil these spe-
cifications, then the speaker should be controlled using a Kling & Freitag system
controller with limiter function. This is the only way overloading and that the risk of
fire can be avoided. The results of such a power amplifier defect of cannot be avoi-
ded by the controller.

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 C2
Controller has a special filter for this purpose, which can be activated with the 'Top-Low
Cut' switch.)
