1. General Safety Instructions for Speakers
Mounting the speakers
To prevent injury, this equipment must be securely placed on the floor or secured to
the wall according to the mounting instructions on page
16 ( Mounting Instructions for
Speakers ). Please note that speakers can move as a result of vibrations. To prevent
them from falling from their mounted position, they must be secured properly . If the
weight of the speaker exceeds 20 kg then it is necessary for two people to carry it .
Speakers may only be mounted to wall and ceilings by qualified personnel . The speak-
ers must be hung by using at least two of the designated flying points. The same applies
when lifting and aligning the speakers
.
Never use signal cables or power cords for suspending, aligning or securing the systems.
When laying the connecting cables, make sure that nobody can trip
.
For mobile and fixed installations, use only assembly equipment from KLING & FREITAG .
Ensure that all installation connections comply with the applicable safety guidelines and
that the size and strength are sufficient. Further instructions are in our user's manual for
assembly equipment and in the general safety instructions for speakers and assembly
equipment
.
For mobile and fixed installations, use only assembly equipment from KLING & FREITAG.
Make sure to observe the included safety and mounting Instructions for loudspeakers
and accessories
.
Speakers and rigging equipment must be visually examined at regular intervals. If
there are signs of wear, they must be replaced immediately. Furthermore, screwed
connections of supporting parts must be checked routinely
.
Protecting the speakers / operating safety
In general, audio signals should not be overdriven. This may be caused by mixing consoles,
equalizers, effect equipment, etc. and should be indicated on this equipment. When a power
amplifier is overloaded at the output (clipping), then the amplifier should activate a clipping
warning signal. Power amplifiers can also be overloaded at the input circuit without the
amplifier signalling the clipping, i.e. when there is not sufficient headroom in the input cir-
cuit. We, therefore, recommend turning up the power amplifiers all the way and adjusting
the level before the power amplifier in order to avoid overloading the input circuit. In any
case, the signal must be reduced as soon as it sounds unnaturally distorted.
− To protect the speakers from being destroyed, they should only be operated with
professional power amplifiers with a maximum rated power of 1400W@6 Ω
(equivalent 2100W@4 Ω).
− If power amplifiers have power ratings lower than mentioned above, then it is impera-
tive that a clipping limiter is used to protect the speaker even if it is used with a Kling &
Freitag system controller.
− Operating safety and maximum performance of the LINE 212 System can only be
guaranteed when used with the C2 Controller. We cannot offer a guarantee for
overload damage resulting from use with a controller aside from the C2.
For damage caused by
− overloading the speakers
− using the speakers with power amplifiers other than those recommended above
− using the speakers without a controller or with a controller other than the K&F C2
Controller,
Kling & Freitag GmbH does not assume warranty and excludes liability for possible con-
sequential damage
