4. Instructions for Versions with ‘100 V’ Option
Kling & Freitag speakers are fitted with high-quality toroidal transformers. This serves
to minimize loss of sound quality. Highly professional sound reinforcement results can
be achieved using 100 V Kling & Freitag speakers.
4.1 Reasons for choosing Speakers with 100 V Technology
−
Reduction in conduction loss.
−
Easy assembly 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 V amplifier.
−
Speakers are galvanically isolated.
−
Speakers can be integrated into existing 100 V systems.
4.2 Connecting Diagram of the 100V Speaker Inputs
The 100 V transformer for the E 90 MK II has 3 taps. These enable the speaker to be
operated at 50 VA, 100 VA or 150 VA. Which tap is connected to which pin can be
seen below.
5. Instructions for Suspending the Speakers
The speakers may only be suspended by trained specialised personnel.
Please follow the accompanying safety and assembly instructions carefully as
well as the required safety factors. Pay attention to the corresponding na-
tional safety regulations.
Speaker systems, whether single or connected to one another, must always be se-
cured to a second separate point.
Ensure that all connections are secured to prevent their detaching on their own and
that only admissible statically tested and sufficiently sized connecting devices, ropes
and chains are used.
Do not mount any additional loads to the M6 thread inserts on the bottom of
the speakers.
