4. Configurazione e connessione

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

4.1 Posizionamento degli altoparlanti

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.
Monitorare l'uso: The EKX-12 features a 40° monitor angle with rubber feet, allowing it to be used as a floor monitor.
Montaggio su palo: The speaker includes an aluminum pole mount receptacle for use with standard speaker poles.

4.2 Connessione a un Amppiù vivace

Spegni: Assicurati che amplifier sia spento prima di effettuare qualsiasi connessione.
Cavi degli altoparlanti: 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).
Connetti altoparlante: Connect one end of the speaker cable to the input connector on the EKX-12.
Collegare Amplificatore: Connect the other end of the speaker cable to the corresponding output channel on your power amplificatore. Assicurarsi che la polarità sia corretta (+ con + e - con -).
Adattamento di impedenza: Verificare che il amplifier's output impedance matches the speaker's nominal impedance (typically 8 ohms for passive speakers).

5. Funzionamento

Once connected, follow these steps for basic operation:

Volume iniziale: Imposta il amplifier's master volume to its minimum level.
Accensione: Turn on your audio source (mixer, instrument, etc.), then turn on the power amppiù vivace.
Regola volume: Aumentare gradualmente la amplifier's master volume to the desired listening level. Monitor for any signs of distortion.
Controllo del sistema: Play a familiar audio track to ensure all speakers are functioning correctly and the sound is clear.
Spegni: When finished, turn off the power amplifier first, then the audio source.

6. Manutenzione

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

Pulizia: Use a soft, dry cloth to clean the exterior of the cabinet. For stubborn dirt, a slightly damp È possibile utilizzare un panno, seguito da un panno asciutto. Evitare detergenti abrasivi o solventi.
