2. Sikkerhedsoplysninger

Please read and understand all safety instructions before operating the loudspeaker. Retain this manual for future reference.

  • Magt: This is a passive loudspeaker and requires an external amplifier. Sørg for amplifier's power output matches the speaker's power handling capabilities to prevent damage.
  • Ventilation: Ensure adequate airflow around the loudspeaker, especially if used in an enclosed space, to prevent overheating.
  • Montering: Use only approved mounting hardware and follow all instructions for pole mounting or suspension. Ensure the mounting surface or stand can support the speaker's weight (17.4 kg / 38.36 lbs).
  • Kabler: Use high-quality speaker cables with appropriate gauge for the power and distance.
  • Høreværn: Prolonged exposure to high sound pressure levels can cause permanent hearing damage. Use hearing protection when operating the system at high volumes.

4. Opsætning og tilslutning

Proper setup is crucial for optimal performance and safety. The EKX-12 is a passive speaker, meaning it requires an external power amplivligere.

4.1 Højttalerplacering

  • Main FOH (Front of House): Place speakers on stands or suspend them to ensure the sound reaches the audience effectively. The 90° x 60° coverage pattern is ideal for mid-size stages.
  • Skærmbrug: The EKX-12 features a 40° monitor angle with rubber feet, allowing it to be used as a floor monitor.
  • Polmontering: The speaker includes an aluminum pole mount receptacle for use with standard speaker poles.

4.2 Tilslutning til en Amplivligere

  1. Sluk: Sørg for din ampapparatet er slukket, før der foretages nogen tilslutninger.
  2. Højttalerkabler: Use high-quality speaker cables with appropriate connectors (e.g., Speakon or 1/4-inch TS, depending on the speaker's input and amplifier's output).
  3. Tilslut højttaler: Connect one end of the speaker cable to the input connector on the EKX-12.
  4. Forbinde Amplivligere: Connect the other end of the speaker cable to the corresponding output channel on your power ampSørg for korrekt polaritet (+ til + og - til -).
  5. Impedanstilpasning: Bekræft, at amplifier's output impedance matches the speaker's nominal impedance (typically 8 ohms for passive speakers).

5. Betjening

Once connected, follow these steps for basic operation:

  1. Indledende volumen: Indstil amplifier's master volume to its minimum level.
  2. Tænd: Turn on your audio source (mixer, instrument, etc.), then turn on the power amplivligere.
  3. Juster lydstyrken: Øg gradvist amplifier's master volume to the desired listening level. Monitor for any signs of distortion.
  4. Systemtjek: Play a familiar audio track to ensure all speakers are functioning correctly and the sound is clear.
  5. Sluk: When finished, turn off the power amplifier first, then the audio source.

6. Vedligeholdelse

Regular maintenance helps prolong the life and performance of your loudspeaker.

  • Rensning: Use a soft, dry cloth to clean the exterior of the cabinet. For stubborn dirt, a slightly damp en tør klud kan bruges. Undgå slibende rengøringsmidler eller opløsningsmidler.
  • Gitter: Periodically check the front grille for dust or debris accumulation. A soft brush or vacuum cleaner can be used to gently remove it.
  • Forbindelser: Sørg for, at alle kabelforbindelser er sikre og fri for korrosion.
  • Opbevaring: When not in use, store the loudspeaker in a dry, temperature-controlled environment. Consider using protective covers to prevent dust and physical damage.
  • Inspektion: Regularly inspect the cabinet, handles, and mounting points for any signs of wear or damage.
