OPERATING DETERMINATIONS

This speaker system is a passive system which can be used for permanent installations or for mobile use. 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".

Speaker systems must only be operated by trained persons.

Danger of Life due to crashing speaker systems or hearing loss due to excessive sound pressure levels! The different local conditions have to be considered in terms of safety rules.

This speaker system must never be operated or stockpiled in surroundings where splash water, rain, moisture or fog may harm the speaker system. When using smoke machines, make sure that the speaker system is never exposed to the direct smoke jet and is installed in a distance of 0.5 meters between smoke machine and speaker system.

The ambient temperature must always be between -5^ C and +45^ C. Keep away from direct insulation (particularly in cars) and heaters.

The relative humidity must not exceed 50 % with an ambient temperature of 45^ C.

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

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.

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).

This speaker system must never be installed higher than 100 cm.

DANGER!

This speaker system must never be installed on a wall-mounting because the secondary attachment cannot be fixed.

Speaker-systems may only be installed on top of other speaker-systems if the systems are protected against slipping and flipping over (e.g. via appropriate clamping belts).

DANGER!

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

For monitor speakers:

This speaker system must never be stacked on top of another speaker system.

English

If the original speaker system is equipped with an appropriate flange:

This speaker system can be installed on top of a subwoofer (satellite system), on a speaker stand or an appropriate stand. The carrying capacity of the distance tube, the speaker stand or the stand must never be exceeded.

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.

Operate the speaker system only after having familiarized with its functions. Do not permit operation by persons not qualified for operating the speaker system. Most damages are the result of unprofessional operation!

This speaker system is not designed for road use. The speaker system is designed only for seldom transports. When transporting this speaker system, it must be moved carefully and without force.

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:

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 organiser 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.

English

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.

Overview on the different noise levels

10 dB Heartbeat
20 - 30 dB Whisper
40 dB Average home
50 dB Light traffic
60 dB Normal conversation
70 dB Vacuum cleaner
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 recognize 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 must only be connected with an appropriate power amplifier. The amplifier power must correspond with the speaker-system power. An amplifier with too little power can also destroy a speaker-system with a higher power range.

English

Choosing an appropriate power amplifier

Before starting with the installation, you must clarify how many speaker-systems you would like to install in the room.

In order to increase the sound pressure level two speaker-system pairs should be connected with the power amplifier. Please note that the impedance is only half the value when you connect two speaker-systems with one channel of the power amplifier. Please make sure that the power amplifier is qualified for this operation mode.

When connecting further speaker-system pairs (e.g. 3 pairs) to the same power amplifier, the impedance lowers even further. You must always make sure that the power amplifier is qualified for the new impedance. If the impedance of the speaker-system is lower than the lowest allowed amplifier impedance, the amplifier and the speaker-systems may be damaged.

Furthermore, you must define the operation mode for your system. If the power amplifier is to be used in stereo-mode, the power is lower as in e.g. mono bridged mode.

The following descriptions refer to OMNITRONIC power amplifiers. You may also use other appropriate power amplifiers.

Operation modes

Stereo operation

Normal operation mode of an amplifier, in which every channel gets its own signal. The most commonly used mode of amplifiers is stereo-operation at 4 Ohms. Make sure that the operation-mode-switch is correctly set.

Calculation number of speakers - impedance

E.g. 1 speaker à 8 Ohm = 8 Ohm

2 speakers à 8 Ohm = 4 Ohm (parallel)
2 speakers à 8 Ohm = 16 Ohm (in line)
3 speakers à 8 Ohm = 2.66 Ohm (parallel), only for amplifiers capable of handling 2 Ohms
2 speakers à 8 Ohm = 24 Ohm (in line)
4 speakers à 8 Ohm = 2 Ohm (parallel), only for amplifiers capable of handling 2 Ohms

N.B.:

The input-impedance of the speaker-systems should at least be the same or even higher than the output-impedance of the amplifier.

Parallel operation

Possibility to run the amplifier in mono-mode, i.e. via one input channel. In parallel operation mode, the voltage remains the same, the current is doubled. Consequently, the output impedance is limited to the minimum value of one individual channel.

Connect the input signal to the input-plug CH-1.

Make sure that the amplifier is disconnected from the mains before you set the operation-mode-switch to parallel.

Bridge the red pole sockets of Output Channel 1 and Output Channel 2.

Connect your speakers to the Speaker-socket Output CH-1.

Caution! Before switching on your amplifier, please refer to the explanations under Operation.

Adjust the level with the gain-control CH-1 on the front panel.

Bridging

Possibility to run the amplifier in mono-mode, i.e. via one input channel. In bridged operation mode, the current remains the same, the voltage is doubled. Consequently, the output impedance is doubled.

For stereo-operation, 2 amplifiers are needed.

Connect the input signal to the input-plug CH-1 on the rear panel.

Make sure that the amplifier is disconnected from the mains before you set the operation-mode-switch on the front panel to Bridge.

Connect your speakers to the red Speaker-socket Mono Bridged.

Caution! Before switching on your amplifier, please refer to the explanations under Operation.

Adjust the level with the gain-control CH-1 on the front panel.

Choosing appropriate connection cables

The speaker-system must only be connected via a sufficiently dimensioned cable. Too thin cables lead to cable heatup or enormous power loss and loss in sound-quality.

For all speaker-systems up to 400 Watts, we recommend a cable diameter of 2.5 mm ^2 , for all other speaker-cables 4 mm ^2 .

A high damping factor of your amplifier supplies a clear sound reproduction. Unnecessarily long and thin cables will influence the damping factor and thus the low frequencies in a negative way. In order to safeguard good sound quality, the damping factor should lie around 50. The longer a cable has to be, the thicker it should be.

In this respect, a damping factor of 200 will be reduced to 47 (8 Ohms) when using a 10 m long, 2.5 mm ^2 speaker cable. The power loss at 8 Ohms is 1.63 %, at 4 Ohms 3.25 % and at 2 Ohms even 6.5 %.

The maximum cable length is 30 meters!

Connections

Your speaker-system is equipped with 4-pole, lockable Speaker-sockets. For locking the connection turn the plug to the right. For unlocking pull the unlock button and turn the plug to the left and pull it out of the socket.

INSTALLATION

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

For speaker-systems with felt cover: the speaker-system is covered with resonance damping felt. This felt is easily flammable. When choosing the installation area, make sure that no heat like glowing cigarettes, open fire, heaters etc. can inflame the speaker-system. In order to avoid damage and fire hazard we recommend to install the speaker-system out of the reach of people.

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.

English

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 speaker-systems 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 covers 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.

Installing the speaker-cables

Connect the speaker-systems among each other using the inputs and outputs. Connect the cable of the first speaker-system with the Speaker-socket Output CH-1 and Output CH-2 of the amplifier. The signal will be transmitted to the individual speaker-systems.

Always treat the cables carefully and protect them from damages during transportation.

Install the cables always in a structured way and protect them from damage.

The cables must be installed in a way that no person can stumble over them. Always fix the cables with an appropriate tape.

Both cables should be of the same kind.

Both cables should have the same length.

Both cables should be installed directly (no loops, S-shaped overlengths)

Always install the cables far away from power cables (never closely parallel)

Never put heavy objects like speaker-systems, flightcased etc. on cables.

Never wind up cables tightly around the elbow, but rather sleek with an interior diameter of 20 to 30 cm.

English

Use in public areas

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.

For monitor-speakers:

This speaker-system must never be stacked on top of another speaker-system.

English

Satellite-systems

Diagram of a speaker with two speakers and a top-mounted speaker (no text or symbols)

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

Line drawing of a speaker-mounted stand with tripod base (no text or symbols)

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.

English

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.

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!

Installation on a wall-mounting

DANGER!

This speaker-system must never be installed on a wall-mounting because the secondary attachment cannot be fixed.

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.

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.

We recommend a frequent cleaning of the speaker-system. Clean the carpet finish with a vacuum-cleaner. For cleaning the speaker-grilles, 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.
