Speaker System ELA MK II
1. General Advice for Using Loudspeakers
Erection of the Loudspeakers
To ensure that the loudspeakers do not topple or fall and cause damage or injury, please always
take care to mount the loudspeakers securely.
At all times hang up the speakers on at least 2 of the 10 threads available. The same goes for the
lifting and setting up of the speakers.
Do not hang more than three loudspeakers on top of each other without using special Kling &
Freitag installation fittings.
Please check whether the installation connections comply with applicable safety guidelines and if
they are of an adequate size or strength. You will find information about this in our Installation
Fittings User Manual.
For both mobile and fixed installations, please use only assembly fittings provided by Kling &
Freitag. Make sure to observe the installation instructions and safety notes shown in the Installa-
tion Fittings User Manual.
Assembly fittings and loudspeakers should undergo regular visual checks. At any sign of wear,
fittings should be replaced immediately. Furthermore, all screwed connections should be checked
regularly.
Do not Install Loudspeakers in any of the Following Places:
-
Where the speakers are permanently subjected to direct sunlight (with the exception of the
‘All Weather’ version, which has been specially developed for outdoor usage).
-
Where the loudspeakers are subjected to dampness (with the exception of the ‘All Weather’
and ‘Outdoor’ versions, provided the latter are not subjected to direct weather conditions).
-
Where the loudspeakers are subjected to strong vibrations and dust.
Damage Caused by Magnetic Fields of the Loudspeakers
Loudspeakers are surrounded by a permanent magnetic field even when they are not connected
up. Therefore, please take care especially during transport and installation that a distance of 1m
away from magnetic data carriers and computers/video monitors is kept.
Protection of the Loudspeakers
For the selection of Power Amplifiers, it should be made sure that their dimensions are sufficient.
Power Amplifiers which have a too low power output can cause damages to the loudspeakers
through their overload (clipping).
Power Amplifiers should never be overloaded. Especially for Power Amplifiers with a nominal
power higher than that of the loudspeaker, overload may cause damages to the loudspeakers.
The following Signals may damage the Loudspeakers
-
Permanent high-pitched signals with high frequency and continuous tone through feedback.
-
Permanently distorted signals with high power.
-
Noises that occur when an appliance is connected, disconnected or switched on while the
amplifier is on.
Advice on Protection Circuits
The ELA MK II is equipped with protection circuits for the 1“ tweeter as well as the crossover,
which interrupt the signal flow in the case of extreme overload. If the loudspeaker switches off,
decrease the volume and after a few seconds the loudspeaker will automatically switch itself on
again. If the halogen lamp is blown, you can replace it on the crossover circuit (Position and
specification see illustration on page 4).
Avoid Ear Damage
Please do not risk damaging your ears, by staying too close to operating speakers even if you feel
that the volume is low enough.
