8.3 Wiring�instructions
• Before connecting your SONA 5 loudspeaker switch off all equipment and turn down all level
controls.
• Only use high-quality speaker cables with a sufficient wire gauge. The wire gauge depends on
the length of the speaker cable.

=�Required�Cable�Length�(m)�/�(2�x�Speaker�Impedance�(Ω))
• For connections to the power amplifier inputs, please use 2-pin shielded microphone cable (bal-
anced) with high-quality connectors.
• Avoid ground loops.
• Please pay attention to the pin assignments shown in this manual.
• Make sure that the +/- polarity of the speakers at the amplifier is correct. When simultaneously
using power amplifiers from different manufacturers, be sure to use the correct specific pin con-
figuration. It may be necessary to modify the pin configuration on the power amplifiers or on
the connectors leading to them.
• Upon completing the wiring, ensure that the connected speaker channels are working in phase.
To do so, use i.e. a phase checker. A phase error can also be recognized when the connected
channels are used simultaneously. During simultaneous use the bass frequencies become no-
tably quieter or the mid-frequencies such as voices cannot be located.
• If several loudspeakers are connected, the signal can be linked through parallel from one loud-
speaker to the next. Please make sure that the total impedance of the loudspeakers R(Ω) is not
lower than the minimal impedance indicated on the power amplifier.

9. Notes�for�the�Version�with�'100�Volt'�Option
Kling & Freitag speakers with '100V' option are fitted with high-quality transformers. This serves to
minimize loss of sound. Highly professional sound reinforcement results can be achieved using '100
Volt' Kling & Freitag speakers.
Reasons�for�choosing�Speakers�with�100�Volt�Transformers:
• Reduction in conduction loss.
• Easy installation of a loudspeaker network due to simple parallel wiring. The sum of the output
power of the individual speakers (stated as VA = W) must not exceed the output power of the
100 Volt amplifier.
• Speakers are galvanically isolated.
• Speakers can be integrated into existing 100 Volt systems.
