5. Instruccions de funcionament

Once installed, follow these guidelines for operating your subwoofer:

• Període d'entrada: Espereu un període d'adaptació d'unes 20-30 hores d'escolta moderada abans de fer funcionar el subwoofer a volums alts. Això permet que els components de la suspensió s'afluixin i funcionin de manera òptima.
• Configuració de guany: Estableix el ampguany del lificador correctament per coincidir amb el volum de sortidatage of your head unit. Incorrect gain settings can lead to distortion and potential damage.
• Configuració de crossover: Use a low-pass filter (LPF) to ensure the subwoofer only reproduces low frequencies. A typical LPF setting for a 15-inch subwoofer is between 60Hz and 80Hz.
• Filtre subsònic: Utilize a subsonic filter (high-pass filter for the subwoofer channel) to protect the subwoofer from playing frequencies below its resonant frequency (Fs). A setting around 25-30Hz is often appropriate.
• Escolta la distorsió: If you hear any distortion, reduce the volume or amplifier gain immediately. Prolonged operation with distortion can cause irreversible damage.
