6.1 Amplifier Controls (Refer to Figure 4.2)

• QLIGĦ: This control matches the input sensitivity of the amplifier to the output level of your head unit. Start with the gain set to minimum (fully counter-clockwise). Play a familiar track with strong bass at about 75% of your head unit's maximum volume. Slowly increase the gain until you hear distortion, then back it off slightly.
• LPF (Filtru Low-Pass): This control sets the upper frequency limit for the subwoofer. Frequencies above this setting will be filtered out. Adjust the LPF to blend smoothly with your main speakers. A common starting point is between 80Hz and 100Hz. Experiment to find the best integration.
• FAŻI: This switch (0°/180°) helps to align the subwoofer's output with your main speakers. Listen to a bass-heavy track and switch between 0° and 180°. Choose the setting that provides the most impactful and cohesive bass.
