Safety Instructions
3.1
Notes for Mounting the Speakers
Warning
Mount the speakers securely. To avoid injury or damage, always be sure to mount the
speakers securely so that they do not fall.
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.
Run the cables in a way that nobody can trip over them.
3.2
Instructions for Speaker Stacking
Warning
Falling speakers pose the threat of fatal injuries to people near them!
Be sure to follow the relevant national specifications, norms, and safety regulations.
Always make sure that a sufficient safety level is still given, even when outside forces have
an additional impact on the stacked speakers. Before setup, carefully ascertain if there are
any possible outside forces that could result in the array falling over. (Slant of the ground /
the bearing capacity of the ground / wind / person or vehicle impact, etc.). A technical expert
who is responsible for the setup must evaluate and determine necessary measures (including
calculating the statics). If necessary, obtain expert proof of stability.
Stacked systems may not fall over even if they are inclined by 15° in each direction. If this
requirement is not fulfilled, then it is necessary to take steps to achieve compliance. Possible
measures include strapping it to an appropriate base structure or fastening it using safety
straps. A planned tilt of the loudspeakers ist not permissible. In calculations, the tilted setup
serves the purpose of levelling out unevenness.
With the set-up systems for which you cannot verify the structural safety without safeguards,
you must secure them to prevent sliding or tipping in order to provide proof of this safety. To
secure the system from tipping over, use water tanks or floor bolts. Other possible measures
include strapping it to a suitable substructure or tying it using safety straps.
For outdoor and trade fair venues in which wind loads must be considered, additional proof
of stability is necessary.
Make sure that the stacking feet of subwoofers stacked on top of one another are securely
positioned in the grooves of the lower speaker.
If you place a top speaker on a PASSIO SUB 12 you must always strap the speakers to one
another and secure them from falling over.
3.3
Preventing Hearing Damage
Caution
Keep your distance from operating speakers. This equipment is capable of delivering sound
pressure levels in excess of 90 dB SPL, which may cause permanent hearing damage.
3.4
Protecting the Speakers / Operating Safety
PASSIO SUB 12 speakers may only be used in combination with a K&F SystemAmp/
SystemRack.
In general, audio signals must 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 activates a clipping
warning signal. In any case, the signal must be reduced as soon as it sounds unnaturally
distorted.
