6. Çalıştırma

Instructions for operating your LD Systems SUB 88 A subwoofer.

1. Güç Açık: Once all connections are made, switch the POWER button to the ON position. The POWER LED should illuminate.
2. Ses Ayarı: Start playing audio through your system. Slowly increase the ALT SEVİYE knob until the desired bass level is achieved. Ensure the LIMIT LED does not illuminate frequently, as this indicates signal clipping.
3. Geçiş Ayarı: Ayarla SUB CROSSOVER knob to blend the subwoofer's output seamlessly with your main speakers. A lower setting (e.g., 80 Hz) is suitable for larger main speakers, while a higher setting (e.g., 120 Hz or more) may be needed for smaller satellite speakers. Experiment to find the best balance.
4. Faz Ayarı: While playing music with strong bass, toggle the ALT FAZ switch between 0° and 180°. Choose the setting that produces the most impactful and defined bass. This compensates for acoustic phase differences between the subwoofer and main speakers due to their placement.
5. İzleme: Pay attention to the SIGNAL and LIMIT LEDs. The SIGNAL LED confirms audio input. If the LIMIT LED flashes frequently or stays lit, reduce the input signal level from your source or decrease the SUB LEVEL to prevent distortion and potential damage.
