6.1 Amplifier Controls (Refer to Figure 4.2)

• GWIRITSANI: 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 (Zosefera za 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.
• PHASE: 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.

6.2 Remote Gain Control

The remote gain control allows you to adjust the subwoofer's output level conveniently from your listening position without affecting the amplifier's main gain setting. This is useful for making quick adjustments based on music genre or personal preference.
