• INPUT LEVEL (MIN/MAX): ការគ្រប់គ្រងនេះត្រូវនឹង amplifier's input sensitivity to the output level of your head unit. Start with the level at minimum, then slowly increase it until you hear distortion, then back off slightly.
• CROSSOVER (L.P.F. 35Hz ~ 250Hz): The Low Pass Filter (LPF) allows frequencies below the set point to pass through to the subwoofer. Adjust this to blend the subwoofer's output seamlessly with your main speakers. A common starting point is 80Hz-100Hz.
• CROSSOVER (H.P.F. 5Hz ~ 35Hz): The High Pass Filter (HPF) allows frequencies above the set point to pass. For subwoofers, this is typically used to filter out extremely low, inaudible frequencies that can waste amplifier power and potentially damage the subwoofer. Set it to the lowest useful frequency, often around 5Hz-10Hz.
• BASS BOOST (FREQ 35Hz ~ 60Hz, GAIN 0dB ~ +15dB): This control allows you to boost specific bass frequencies.
  • ប្រេកង់៖ ជ្រើសរើសប្រេកង់កណ្តាលសម្រាប់ការជំរុញបាស។
  • ទទួលបាន៖ Adjusts the amount of boost applied to the selected frequency. Use sparingly to avoid distortion and potential damage to your subwoofer.

Recommendation: Make small adjustments and listen carefully to the sound. It is often best to set the gain and crossover points with test tones or familiar music to achieve the desired sound quality.
