Stand Installation
The retainer nut of the Mounting Arm is equipped with a 5/8" thread into which a reducer
with an inner thread of M10 is screwed. You can exchange this thread reducer for a
commercially available reducer for microphone stands so you can mount the Mounting Arm
onto a microphone stand. Depending on the design of the stand, the thread reducer for
microphone stands have a 3/8" or a 1/2" inner thread that fit onto the thread bolts of the
stands.
Exchange the provided 5/8" thread
reducer with a standard thread reduce for
stands (A).
Screw the the thread reducer (A) onto
the bolt of the stand by hand. Make sure
the slit of the thread reducer is facing the
stand.
Using a 19 mm jaw spanner, screw the
retainer nut onto the bolts of the stand.
To ensure that the speaker does not
loosen and cannot turn, you must screw
the retainer nut tightly onto the knurled
nut of the stand.

Proper Alignment of the Loudspeakers
Please note that precisely targeted speaker systems can significantly improve the acoustic
result. It is not possible to make generalities about the alignment of specific systems because
the room has a substantial influence on the signal and the audible result.
As a rule, the mid- and high-transducers of loudspeakers should be mounted above the
audience's face value, so that the sound distribution cannot be shadowed.
In many cases it is advisable to mount a loudspeaker higher, so that the sound will be
distributed throughout the room more evenly. Low standing systems result in a greater
difference in volume between front and back seats than higher standing systems.
To simulate the correct alignment of the speakers beforehand, there are various programs
such as ‘EASE’ or ‘Ulysses’. On the homepage www.kling-freitag.de, KLING & FREITAG
provides the simulation data for the speakers to be downloaded.

Operation with or without a controller
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" beginning on page 7.
•
For safe operation, they must only be operated with professional power amplifiers
with a maximum rated output power of 200W@16Ohm (equiv. 400W@16Ohm or
800W@16Ohm).
•
If power amplifiers have power ratings lower than 100W@16Ohm, then it is imperative
that the amplifiers have clipping limiters. Alternately, you can also insert a clipping
limiter before the amplifier.
•
To protect the loudspeaker from mechanical damage when high SPL is required a
highpassfilter of 24 dB/oct. at 60 Hz has to be inserted into the signal chain.
