Step 4:
Drill the holes.
Step 5:
Hold the wall-mounting in the desired position and tighten the screws.
Step 6:
Install the Control 5 speaker on the wall-mounting.
Step 7:
Install the safety-rope in the wall-mounting’s safety eyelet and the Control 5.
For overhead use, always install a safety-rope that can hold at least 12 times the weight of the fixture. You
must only use safety-ropes with quick link with screw cap. Pull the safety-rope through the mounting-bracket
on the speaker-system and over the trussing system or a safe fixation spot. Insert the end in the quick link
and tighten the safety screw.
The maximum drop distance must never exceed 20 cm.
A safety rope which already hold the strain of a crash or which is defective must not be used again.
DANGER TO LIFE!
Before taking into operation for the first time, the installation has to be approved by an expert!
Suspended installation
This speaker-system must never be suspended - Danger to Life due to crashing
speaker-systems!
OPERATION
After having connected your amplifier to the mains, turn both gain controls counter-clockwise to Min-position.
The last device to be switched on is the amplifier. The "ON" and "PROTECT" LED light up now. If it does not,
check if the amplifier is connected to the mains correctly.
After the turn-on delay the speakers are activated (PROTECT-LED is off).
After having set the volume controls of the pre-amplifier in null-position, turn the gain controls of your
amplifier to mid-position. You must not hear any loud humming. If there is humming nevertheless, check the
connecting cables between the pre-amplifier and the amplifier (switch off components before). Now adjust
the volume with the gain controls CH-1 and CH-2.
Caution!
Increase the level of each channel only so far that the CLIP-LED lights up shortly. Thus, you avoid
that the output signal is distorted and your speakers are damaged.
When operating the speaker-system, please make sure that the loudspeakers always sound well. When
distorsions can be heard, either the amplifier or the loudspeaker is overloaded. Overloads can quickly lead to
amplifier or speaker damage.
In order to avoid damage, please reduce the volume immediately when distortions can be heard. When
speaker-systems are destroyed by overload, the guarantee becomes void.
Always check the sound pressure level with a meter in order to keep to the threshold.
If you want to switch off the system,
switch off the amplifier first
and then the pre-amplifiers in order to
avoid acoustic shocks on the speakers.
CLEANING AND MAINTENANCE
The operator has to make sure that safety-relating and machine-technical installations are inspected by an
expert after every four years in the course of an acceptance test.
The operator has to make sure that safety-relating and machine-technical installations are inspected by a
skilled person once a year.
