7. Funcionament del Ampmés viu
Un cop instal·lat, ajusteu el ampConfiguració del lificador per a un rendiment so òptim.
- Ajust de guany: Start with the gain control at its minimum (0.2V). Play a familiar track with strong bass at about 75% of your head unit's maximum volume. Slowly increase the amplifier's gain until you hear distortion, then back off slightly. The clipping indicator on the remote bass knob can assist in this process.
- Filtre de pas baix (LPF): Set the LPF to filter out frequencies above your desired subwoofer range, typically between 60Hz and 100Hz, depending on your main speakers and personal preference.
- Filtre subsònic: Adjust the subsonic filter to protect your subwoofers from playing frequencies below their resonant frequency, usually set between 20Hz and 30Hz.
- Intensificació dels sons més greus: Use the bass boost sparingly. Excessive bass boost can lead to distortion and potential damage to your subwoofers. Start at 0dB and increase only if needed, listening carefully for distortion.
- Control de fase: Experiment with the 0° and 180° phase settings to find the one that provides the most impactful and coherent bass response with your other speakers.
