  • Upami nganggo LFE INPUT, this control is bypassed. Set your AV receiver's subwoofer crossover frequency.
  • Lamun ngagunakeun LINE IN or HI TINGKAT DI, adjust the FREQ control to blend the subwoofer's output with your main speakers. A good starting point is typically 80Hz-100Hz, but this may vary depending on the size and frequency response of your main speakers. Smaller main speakers usually require a higher crossover frequency.
• PHASE (0° - 180°): The phase control helps to ensure that the subwoofer's sound waves are in sync with your main speakers.
  • Play music with a consistent bass line.
  • While listening from your primary listening position, slowly adjust the PHASE control from 0° to 180°.
  • Stop at the position where the bass sounds the loudest and most impactful. If the bass sounds weak or hollow, try adjusting the phase.
• BASS BOOST: Use the BASS BOOST controls (Level and Freq) to fine-tune the low-frequency response.
  • Frékuénsi: Select the specific low frequency (25Hz to 50Hz) you wish to boost.
  • tingkat: Adjust the amount of boost (0dB to 12dB) at the selected frequency. Use sparingly to avoid muddy or boomy bass.
