INSTALLATION

The stage monitors can be placed as desired or put onto a PA speaker stand via the stand flange on the lower side. Always install the speakers at a solid, plane, anti-slip, vibration-free, oscillation-free and fire resistant location. 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).

• Stands or satellite systems must only be installed on a plane area with a maximum inclination angle of 5°.
• 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.
• When people are located below the load, all necessary safety measures have to be taken in order to avoid injury.
• The personnel have 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 a balancing foot, has to be created. When choosing the installation material, optimum dimensions have to be chosen in order to secure maximum safety.
• Speaker systems installed on stands or satellite systems may cause severe injuries when crashing! If installing on slippery surfaces, the legs must be secured with screws or nails via the provided holes or an anti-slippery mat has to be used.

Avoiding Feedback

CAUTION!
Do not direct any microphones to the speakers. This can result in dangerous and unpleasant acoustic feedback which will generate a loud whistling sound.
One of the most frequent problems when operating speaker systems is feedback. It can be recognized by howling and growling loudspeakers. Feedback is created when 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. Feedback never covers the whole frequency range but only one over boosted 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. Never hold microphones directly in front of the speaker system!
Extreme levels like feedback, bass hum or the beats of a dropping microphone can destroy the loudspeakers within a 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.

MAKING THE CONNECTIONS

Route the audio signal from a mixer’s monitor or aux output to the SVM-12A When using the monitor mix with several speaker systems, route the audio signal of the first stage monitor to the next monitor via the feed-through output.
Switch off the stage monitor and the units to be connected before making or changing the connections.

Connecting the Signal Source
As signal source, both microphones and units with line level output (e.g. mixer, CD player, keyboard) can be connected to the INPUT jack via XLR or 6.3 mm plugs, balanced and unbalanced.
A good cable run improves the sound quality remarkably. Signal cables should be short and direct, since high frequencies will mostly be absorbed if 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. In order to obtain highest sound quality, only use high-quality cables for connecting the devices. Make sure that the cables are properly fixed.

Connector Configuration

Connecting Two or More Stage Monitors in Series
The LINK jack is connected in parallel to the input jack. Connect this output to the input of another speaker system. Connect further units likewise.

Connection to the mains
Finally, connect the supplied power supply cable to the corresponding input and the mains plug to an outlet (AC 240 V, 50 Hz). The device can also be operated with AC 220 V, 60 Hz~.

OPERATION

1. First turn down the LEVEL control to the left stop position to avoid a possible switching-on noise. Then switch on the stage monitor. The POWER indicator lights.
2. Use the MIC/LINE input selector button to switch the input to microphone or line level according to the signal source connected.
3. Adjust the desired volume for the signal source with the LEVEL control. Only turn up the control to such an extent that the sound reproduction will not be distorted. The LIMIT indicator lights up when the signal level is too high so that the level limitation will be activated. If this indicator lights up frequently, reduce the volume of the input signal accordingly.
4. Press the FLAT/LOW CUT button to activate on the low cut filter. Then the low bass range is attenuated. When the button is disengaged, the frequency response is not affected.
5. When operating the speaker system, please make sure that the loudspeakers always sound well. When distortions can be heard, either the amplifier or the loudspeakers are 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.
6. After operation, set the LEVEL control to minimum, then switch off the stage monitor with the power switch. The power indicator extinguishes.

CLEANING AND MAINTENANCE

DANGER TO LIFE!
Disconnect from mains before starting maintenance operation!

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 device except for the fuse. Maintenance and service operations are only to be carried out by authorized dealers.
If the stage monitor distorts, one of the loudspeakers may be defective. In this case the system should not be operated any more in order to prevent further damage. Please contact your dealer. If clacking sounds are heard from the system, screws may have loosened due to the continuous vibrations. The speaker system should be checked by a specialist.
Should you need any spare parts, please use genuine parts.
If the power supply cable of this device becomes damaged, it has to be replaced by a special power supply cable available at your dealer.
Should you have further questions, please contact your dealer.

Replacing the Fuse
If the fine-wire fuse of the device fuses, only replace the fuse by a fuse of same type and rating.

Before replacing the fuse, unplug mains lead.

Procedure:
Step 1: Open the fuse holder on the rear panel with a fitting screwdriver.
Step 2: Remove the old fuse from the fuse holder.
Step 3: Install the new fuse in the fuse holder.
