Foreign Objects
Never allow objects, especially metal parts, into the device. If metal parts enter, disconnect immediately. Malfunctions or short-circuits can cause mortal injuries.
Secure Setup
Speaker systems can move due to bass beats and vibrations, or accidental pushes. Secure the speaker system against moving or block the area.
Prior to Switching On
Before switching on, set all faders and volume controls to zero or minimum position.
Children and Amateurs
Keep away children and amateurs!
Maintenance and Service
There are no serviceable parts inside. Maintenance and service operations must be carried out by authorized dealers only.
Operating Determinations
The active monitors are suitable for professional applications on stage and for amateur applications in smaller rooms.
Power
This product operates with 220/240 V AC, 50/60 Hz and is designed for indoor use only. Connection cable pins are typically: Brown (Live/L), Blue (Neutral/N), Yellow/Green (Earth/E).
The earth connection is mandatory. For direct connection to the power supply network, a disconnection switch with a minimum 3 mm opening at every pole must be included in the permanent electrical installation. The device must only be connected to an electrical installation compliant with IEC standards and equipped with a Residual Current Device (RCD) with a maximum fault current of 30 mA.
Public and Industrial Use
Operating amplification systems in public or industrial areas requires adherence to specific safety instructions not fully covered here. Operators must inform themselves about current safety regulations.
Maximum Power
Never exceed the maximum power. Ensure loudspeakers sound well; distortions indicate overload of the amplifier or loudspeaker. Reduce volume immediately when distortions occur. Overloads can cause damage and void the guarantee.
Ambient Conditions
Do not operate or stockpile in environments with splash water, rain, moisture, or fog. Moisture can reduce insulation and cause electrical shock. Ambient temperature must be between -5°C and +45°C. Keep away from direct insulation and heaters. Relative humidity must not exceed 50% at 45°C. Operate at altitudes between -20 and 2000 m over NN. When using smoke machines, keep the device at least 0.5 meters away from direct smoke jets.
Installation
Do not shake the device. Avoid brute force. Choose a solid, plane, anti-slip, vibration-free, oscillation-free, and fire-resistant location. Ensure the installation area can support a minimum point load of 5 times the system's load (e.g., 20 kg weight requires 100 kg point load). Stands/satellite systems must be on a plane area with max 5° inclination. For horizontal forces (e.g., wind), take additional safety measures like ballast weights. Mark or block danger areas for inclined tension cables or outriggers. Block a safety area (1.5x max height diameter) before lifting/lowering telescopic tubes. Secure lifted telescopic tubes with secondary securing. Total installation weight must not exceed the area's load capacity. Stands must be out of reach of people. Avoid unintended movement, even in case of fire. The installer is responsible for carrying capacity, safety requirements, and co-worker qualifications. Take measures to prevent injury if people are below the load. Personnel must be instructed on the manual and dangers. Secure against movement and ensure standing safety. Installation is allowed only on carrying areas; use appropriate substructures if needed. Use optimum installation materials for safety. Speaker systems on stands can cause severe injuries if they crash. Secure legs with screws/nails on slippery surfaces or use an anti-slippery mat.
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.
Feedback occurs when a microphone signal is amplified, played back by a loudspeaker, and re-recorded by the microphone. This happens when the playback signal is louder than the original. Feedback affects specific frequencies. Position monitor speakers far from microphones to prevent signal re-recording. Never hold microphones directly in front of speaker systems.
Extreme levels like feedback, bass hum, or dropping microphones can destroy loudspeakers quickly and cause immediate hearing damage. Avoid such levels. Use appropriate equalizers and compressors/limiters.
Operating Elements & Connections
Route the audio signal from a mixer's monitor or aux output to the SVM-12A. For multiple monitors, route the signal from the first to the next via the feed-through output.
Switch off all units before making or changing connections.
Connecting the Signal Source
Microphones and line-level units (mixer, CD player, keyboard) can be connected to the INPUT jack via XLR or 6.3 mm plugs, balanced or unbalanced.
Use short, direct, and high-quality cables for optimal sound quality. Long cables can cause humming and noise; use balanced cables for long runs. Ensure cables are properly fixed.
Connector Configuration
Balanced use of 6.3 mm jack plugs: Tip = Hot (+), Ring = Cold (-), Sleeve = Ground/Shield.
Unbalanced use of 6.3 mm jack plugs: Tip = Signal (+), Sleeve = Ground/Shield.
Balanced use of XLR connectors: Pin 1 = Ground/Shield, Pin 2 = Hot (+), Pin 3 = Cold (-). For unbalanced use, bridge pins 1 and 3.
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.
Connection to the Mains
Connect the supplied power supply cable to the input and the mains plug to an outlet (AC 220-240V, 50/60Hz). The device can also operate with AC 220V, 60Hz.
Installation
Stage monitors can be placed as desired or mounted on a PA speaker stand via the stand flange. Install speakers in a solid, plane, anti-slip, vibration-free, oscillation-free, and fire-resistant location. Ensure the installation area can support a minimum point load of 5 times the system's load (e.g., 20 kg weight requires 100 kg point load).
