Overhead Installation - PSSO CLA-228 MKII TOP Bedienungsanleitung

CLA-218: The subwoofer features 4 castors for convenient tansportation. To prevent accidental
displacement, two of the castors are provided with brakes.
Installing and orienting the speaker system
Always install the speaker systems in a way that a minimum distance of three meters to the audience is kept.
This is the only way to avoid hearing damage for unreasonable listeners. Block the area in front of the
speaker systems with appropriate means.
Avoiding feedback
Extreme levels like feedback, bass-hum or the beats of a dropping microphone can destroy the loudspeakers
within very short time and produce immediate hearing damage. Such extreme levels must be avoided at any
rate. We recommend using appropriate equalizers and compressors/limiters.

Overhead installation

If this speaker system will be installed in a mounting height higher than 1 meter (e.g. on the stage, on a
stage element or on a framework) we speak of overhead installation. For overhead installation, the speaker
system must always be secured with an appropriate secondary attachment.
Please note: when using this speaker system in public or industrial areas, a series of safety instructions
have to be followed that this manual can only give in part. The operator must therefore inform himself on the
current safety instructions and consider them.
Please consider the valid standards and national regulation during the installation!
The installation must only be carried out by an authorized dealer!
The installation of the speaker system has to be built and constructed in a way that it can hold 10 times the
weight for 1 hour without any harming deformation.
When rigging, derigging or servicing the speaker system staying in the area below the installation place, on
bridges, under high working places and other endangered areas is forbidden.
The operator has to make sure that safety-relating and machine-technical installations are approved by an
expert before taking into operation for the first time and after changes before taking into operation another
time.
The operator has to make sure that safety-relating and machine-technical installations are approved by an
expert after every four year in the course of an acceptance test.
The operator has to make sure that safety-relating and machine-technical installations are approved by a
skilled person once a year.
IMPORTANT! Overhead rigging requires extensive experience, including (but not limited to) calculating
working load limits, installation material being used, and periodic safety inspection of all installation material
and the speaker system. If you lack these qualifications, do not attempt the installation yourself, but instead
use a professional structural rigger. Improper installation can result in bodily injury and or damage to
property.
The speaker system has to be installed out of the reach of people.
Caution: Speaker systems in overhead installations may cause severe injuries when crashing down! If you
have doubts concerning the safety of a possible installation, do NOT install the speaker system!
Before rigging make sure that the installation area can hold a minimum point load of 10 times the speaker
system's weight.
DANGER TO LIFE!
