4.2 Crossover and Bass Boost Adjustments
- LPF (Бага нэвтрүүлэх шүүлтүүр): Adjust this control to filter out high frequencies from your subwoofer. A common starting point is 80-100 Hz.
- SUBSONIC Filter: This filter removes extremely low frequencies that are below the audible range and can cause damage to your subwoofer. Set it slightly below your subwoofer's port tuning frequency or around 20-30 Hz.
- BASS ӨСГӨЛ: Use this control sparingly to enhance bass output. Excessive bass boost can lead to distortion and potential speaker damage. Start at 0dB and increase gradually if desired.
