Operation�without�a�Controller
The SONA 5 system is designed so that it can be operated passively without a controller directly on a
power amplifier. Follow the instructions in chapter "[Protecting the Speakers / Operating Safety]" be-
ginning on page 8.
• For safe operation, they must only be operated with professional power amplifiers with a maxi-
mum rated output power of 200W@16Ω (equiv. 400W@8Ω or 800W@4Ω).
• If power amplifiers have power ratings lower than 100W@16Ω, then it is imperative that the
amplifiers have clipping limiters. Alternately, you can also insert a clipping limiter before the am-
plifier.
• To protect the loudspeaker from mechanical damage when high SPL is required a highpassfilter
of 24dB/oct. at 60Hz has to be inserted into the signal chain.
Operation�with�a�Controller
When operating the loudspeaker with amplifers without clipping limiter and nominal amplifier power
less than 100W@16Ω requires to set a Limit Reduction of 3dB for the K&F CD 44 controller. You can
find more detailed information about this option in the K&F CD 44 hardware manual.
