OPERATING DETERMINATIONS

This speaker system is a passive system which must only be used for permanent installations. This product is only allowed to be connected with an appropriate power amplifier and was designed for indoor use only.

The given maximum power of the speaker system describes short-term peaks the system can handle as a maximum. The correspondent RMS power is - as of all comparable systems (also from other manufacturers)

- significantly lower. The maximum power of the speaker system must never be exceeded. When operating the speaker system, please make sure that the loudspeakers always sound well. When distortions 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.

By operating speaker systems with an amplifier, you can produce excessive sound pressure levels that may lead to permanent hearing loss. Please refer to the explanations under "Legal instructions".

Legal instructions

Operating an amplification system can produce extremely high noise levels that may cause a permanent hearing loss. The legal instructions for using an amplification system vary from country to country. The user must always inform himself on the legal instructions valid in his country and apply them to his situation.

Always monitor the sound pressure level when operating an amplification system in discotheques, concerts etc. Never exceed the permissible noise level exposures as specified by your authorities. The monitoring of the noise levels must be documented in an appropriate way.

In Germany, the following instructions are binding:

Strafgesetzbuch § 223 ff: bundesrecht.juris.de/bundesrecht/stgb

TA Lärm: www.umweltdaten.de

DIN 15905-5: www.din.de

Arbeitsstättenverordnung § 15: www.lgl.bayern.de/arbeitsschutz

Berufsgenossenschaftliche Vorschrift BGV B3: www.pr-o.info

VDI-Richtlinie: VDI 2058 Blatt 2: www.vdi.de

Hearing damage caused by high noise levels can be treated as physical injury and persecuted by law.

Please note that the organizer is responsible for keeping to a specified noise level. If this noise level will be exceeded, the event may be cancelled immediately.

If the organizer does not fulfil his safety duties, he is reliable by civil law for any damages occurred, e.g.:

Pay the treatment costs of the damaged person.

Pay a smart money to the damaged person.

Economic damage caused can be demanded from the operator of the amplification system.

20/30 00029746.DOC, Version 1.3

If hired persons work with amplification systems: the noise levels of music events are almost always too high.

This is why the entrepreneur has to set up warning signs and provide hearing protectors. The staff has to use these.

Please note: OMNITRONIC cannot be made liable for damages caused by incorrect installations and excessive noise levels!

Information on hearing loss

More and more young people suffer from hearing loss of 25 decibel or more, mainly caused by loud music from portable cassette recorders and CD players or discotheques.

Everybody operating amplification systems should know to what sound pressure levels he exposes his or the audience's hearing. As an average levels between 75 and 105 dB(A) in the discotheque or 95 and 115 dB(A) at a rock concert are reached. Individual peaks can exceed the pain level at 130 dB(A). Such levels are typical for motor chainsaws or jack hammers.

10 dB Heartbeat

20 - 30 dB Whisper

40 dB Average home

50 dB Light traffic

60 dB Normal conversation

70 dB Vacuum cleaner

Overview on the different noise levels

80 dB Heavy traffic or telephone ringing

90 dB Pneumatic drill

100 dB Power mower

120 dB Boom box in car

130 dB Pain level

140 dB Jet plane 30 meters overhead

It is important to know that doubling the power increases the noise level by 3 dB. The human hearing does only recognizes a doubling of the sound level when the noise level is increased by 10 dB. Damaging the hearing does not depend on the sound level but on the noise level and starts way before the pain level.

Many people deceive themselves by thinking that noise is something they can get accustomed to. It is possible that a positive opinion of a certain noise can reduce the physiological reaction, but the slow impacts on the inner hearing must not be neglected: over stimulation and continuous elimination of the Cortic organ's hair cells.

The reason why some people have got accustomed to a certain noise level and are no longer disturbed is that they have already suffered a hearing damage. This damage make the insensitive to those frequencies forming the loudest part of the noise. Getting accustomed to noise does not mean anything other than trying to get along with the hearing loss in everyday life. The hearing loss itself cannot be healed, it can only be compensated by hearing aids.

Subjectively, the hearing loss feels like dampened ears. This effect weakens with the time, but a loss in hearing sensitivity often remains.

In order to relax the hearing sufficiently, the noise level should not exceed 70 dB(A) for 10 hours. Higher noise levels during this relaxing period can prevent the relaxation and promote a permanent hearing damage

(Tinitus) or hearing loss.

Therefore: Whoever wants to maintain his hearing should use hearing protectors!

START-UP

This speaker-system is directly connected with the audio mixer.

Make sure that the power switch is set to “OFF”. Before you connect the devices, all units have to be switched off and the master-control is set to “0”.

Connections

A good cable run improves the sound quality remarkably. Input cables should be short and direct, since high frequencies will mostly be absorbed if the cables are unnecessarily long. Besides that a longer cable may lead to humming and noise trouble. If long cable runs are unavoidable, you should use balanced cables.

21/30 00029746.DOC, Version 1.3

In order to obtain highest sound quality, only use high-quality cables for connecting the devices. Make sure that the cables are properly fixed.

Connect the Line output via the balanced XLR-plug (except KB-208A). The connection with the next active speaker should be made via a microphone cable.

INSTALLATION

This speaker-system must only be installed at a solid, plane, anti-slip, vibration-free, oscillation-free and fireresistant location.

22/30 00029746.DOC, Version 1.3

Before installing the system, make sure that the installation area can hold a minimum point load of 5 times the system‘s load (e.g. weight 20 kg – point load 100 kg).

The speaker-system must never be installed higher than 100 cm without secondary attachment.

Install the desired number of speaker-systems in the room.

Every speaker-system features two transportation handles. The speaker-system should be carried without force by two persons of the same size. Carrying the speaker-system as one person alone should be avoided as the high weight and the strain could lead to back damages and torsions. Please note that all speakersystems with more than 25 kg weight must be transported with two persons.

Installing and orienting the speaker-system

When installing the speaker-system on e.g. a stage, microphones and turntables should always be located behind the speaker-systems. In this way, you can avoid dangerous and unpleasant feedbacks. If you cannot install the speaker-systems this way, the microphones and turntables should be located as far away as possible from the speaker-systems. When using the speaker-system as monitor-system make sure to avoid feedbacks.

The speaker-systems of a PA-system are normally located left and right to the stage. Do not install the speaker-systems on the stage, but rather on appropriate tables or platforms in front of the stage.

In order to produce a clear sound, the speaker-systems should be installed in a way that they throw the sound over the audience‘s heads. A Full Range speaker-system should be installed at listeners‘ eye level.

Please refer to the safety instructions under Installation.

Loudspeaker combinations need to be installed bass-middle-high (from bottom to top). Make sure that the membranes of all speakers are in one line vertically and horizontally. Only in this way all frequency ranges are produced at the same time and without any time or phase delays.

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 feedbacks

One of the most frequent problems when operating speaker-systems are feedbacks. They can be recognized by howling and growling loudspeakers. Feedbacks are created then a signal is recorded by a microphone, amplified, played back by a loudspeaker and then again recorded by the microphone.

The prerequisite for feedback is that the played back signal is louder than the original signal. A feedback never cover the whole frequency range but only one overboosted frequency.

Make sure that you install especially the monitor-speakers so far away from the microphone that another recording of the microphone signal is impossible.

Extreme levels like feedbacks, 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 to use appropriate equalizers and Compressor/limiters.

Stacking

DANGER!

This speaker-system must never be stacked – Danger to Life due to crashing speaker-systems!

This speaker-system may only be installed on the floor or appropriate stage elements etc.

23/30 00029746.DOC, Version 1.3

24/30 00029746.DOC, Version 1.3

Satellite-systems

A satellite-system is a system where a speaker-system with flange is installed on top of a subwoofer.

The satellite system must always provide enough stability. Satellite systems are only allowed if the subwoofer‘s weight is twice as much as the top speaker‘s weight. Furthermore, the subwoofer‘s base surface must always be sufficiently dimensioned in relation to the top speaker in order to prevent tilting over.

The subwoofer and the top speaker must only be connected via an appropriate distance tube and flange.

The carrying capacity of the distance-tube must never be exceeded.

A satellite system or a combination of speaker system/speaker stand or speaker system/stand must only be installed on the ground!

When choosing the installation-spot, please make sure that such an installation has to be installed in a way that no person can enter the area below the system! Make sure that the respective area is blocked.

An unintended movement of the load has to be avoided – also in case of fire!

The installation is only allowed on carrying areas. In some cases, an appropriate substructure, e.g. via an balancing foot, has to be created.

The system must never be moved before the top speaker is uninstalled!

When choosing the installation material, optimum dimensions have to be chosen in order to secure maximum safety.

Installation on a stand or speaker stand

The speaker-system may only be installed on a stand or speaker stand if the original speaker-system is equipped with an appropriate flange.

Stands or satellite systems must only be installed on a plane area with a maximum inclination angle of 5°.

Caution: Speaker-systems installed on stands or satellite systems may cause severe injuries when crashing!

When using stands or satellite systems under the influence of horizontal forces, e.g. through wind, the standing safety can be impaired. This is why additional safety measures like attaching ballast weights have to be taken.

If inclined tension cables or prolonged outriggers are used, the area of danger has to be marked or even be blocked.

Before lifting or lowering the telescopic tubes, you must always block a safety area around the stand or satellite system. This safety area must have a diameter of 1.5

times the maximum height.

Lifted telescopic tubes always have to be secured with a secondary securing!

The total weight of the installation (=total weight of all individual parts) must never exceed the maximum load of the installation area.

The stand has to be installed out of the reach of people.

An unintended movement of the load has to be avoided – also in case of fire!

The installer is responsible for adhering to the carrying capacity given by the manufacturer, the safety requirements and the qualification of possible co-workers.

25/30 00029746.DOC, Version 1.3

When people are located below the load, all necessary safety measures have to be taken in order to avoid injury.

The personnel has to be instructed on the content of the user manual and on the dangers related with operating stands.

Depending upon the individual installation spot, all necessary measures against movement and for securing the standing safety have to be created.

The installation is only allowed on carrying areas. In some cases, an appropriate substructure, e.g. via an balancing foot, has to be created.

The system must never be moved before the top speaker is uninstalled!

When choosing the installation material, optimum dimensions have to be chosen in order to secure maximum safety.

Loosen the fixation screws of the legs. Pull the legs out until the cross struts stand at a 90° angle to the legs.

Tighten the fixation screws of the legs.

DANGER!

If installing on slippery surfaces, the legs must be secured with screws or nails via the provided holes or a anti-slippery mat has to be used.

Installation of the TV-pin (only for stands)

Attach an appropriate TV-pin to the top end of the stand and fasten it with the handle at the side.

Installation of the speaker-system

Caution: The loads have to be installed in a balanced way.

Caution: The carrying capacity of the stand or speaker stand must never be exceeded!

Install the speaker-system via the flange on the speaker stand or via the TV-pin on the stand.

Make sure that the maximum lifting height of the tube is never exceeded.

Lifted telescopic tubes always have to be secured with a secondary securing!

26/30 00029746.DOC, Version 1.3

Installation on a wall-mounting

The speaker-system may only be installed on a wall-mounting if the original speaker-system is equipped with an appropriate flange.

Before attaching the speaker-system, make sure that the installation area can hold a minimum point load of 5 times the installation‘s weight (e.g. 20 kg weight – 100 kg point load).

The durability of the installation depends very much on the material used at the installation area (building material) such as wood, concrete, gas concrete, brick etc. This is why the fixing material must be chosen to suit the wall material. Always ask a specialist for the correct plug/screw combination indicating the maximum load and the building material.

The wall-mounting must always be installed via all fixation holes.

Do only use appropriate screws and make sure that the screws are properly connected with the ground.

Procedure:

Step 1: On the wall-mounting, there are 4 holes for the installation.

Step 2: Hold the wall-mounting onto the location where it is to be installed.

Step 3: Mark the boreholes with a pen or a suitable tool.

Step 4: Drill the holes.

Step 5: Hold the wall-mounting in the desired position and tighten the screws.

Step 6Install the speaker-system on the wall-mounting.

The wall mounting‘s maximum service life must never be exceeded.

Suspended installation

This speaker-system must never be suspended – Danger to Life due to crashing speaker-systems!

Installation as floor monitor

Attach both monitor feet (except KB-208A) at the rear end of the box.

27/30 00029746.DOC, Version 1.3

Yellow/Green Earth

The earth has to be connected!

If the device will be directly connected with the local power supply network, a disconnection switch with a minimum opening of 3 mm at every pole has to be included in the permanent electrical installation.

The device must only be connected with an electric installation carried out in compliance with the IECstandards. The electric installation must be equipped with a Residual Current Device (RCD) with a maximum fault current of 30 mA.

Switch the device on. After switching on the speaker-system, wait 8 to 10 seconds until you turn the volumecontrol in order to avoid speaker-damage.

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 distortions can be heard, either the amplifier or the loudspeaker is overloaded. Overloads can quickly lead to amplifier or speaker damage.

28/30 00029746.DOC, Version 1.3

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 speaker-system first 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.

The following points have to be considered during the inspection:

1) All screws used for installing the speaker systems or parts of the speaker system have to be tightly connected and must not be corroded.

2) There must not be any deformations on housings, fixations and installation spots (ceiling, suspension, trussing).

3) The electric power supply cables must not show any damages, material fatigue (e.g. porous cables) or sediments. Further instructions depending on the installation spot and usage have to be adhered by a skilled installer and any safety problems have to be removed.

4) If the speaker-system is installed overhead, the inspection must include if the eye-bolts are still well tightened. Otherwise the eye-bolts have to be tightened handtight again.

5) If the speaker-system is secured via clamping belts, the inspection must include if the clamping belts are still well fixed. Otherwise fix clamping belts again.

We recommend a frequent cleaning of the speaker system. Please use a soft lint-free and moistened cloth.

Never use alcohol or solvents!

There are no serviceable parts inside the speaker system. Maintenance and service operations are only to be carried out by authorized dealers.

If the speaker system distorts, one of the loudspeakers may be defective. Test the speaker system once more with another amplifier. If the sound remains distorted, the speaker system should not be operated any more in order to prevent further damage. Please contact your dealer.

If clacking sounds are heard from the speaker system, screws may have loosened due to the continuous vibrations. The speaker system should be checked by a specialist. Especially for public use, the speaker system should be checked before every operation so that the speaker system and the speakers in the systems are always well fixed.

Should you need any spare parts, please use genuine parts.

Should you have further questions, please contact your dealer.

DANGER TO LIFE!
