- naekeun: Controls the amount of bass boost (0 dB to +18 dB).
- PRT (Protection) Indicator: Illuminates nalika amplifier is in protection mode due to overheating, low voltage, or short circuit.
5. Operating and Tuning
5.1 Initial Setup and Gain Matching
- Hurungkeun amplifier gain all the way down (counter-clockwise).
- On your head unit, turn the volume up to about 75% of its maximum level.
- Slowly increase the gain on the amplifier until you hear slight distortion, then back it off slightly until the sound is clear.
- For optimal performance, it is recommended to use a test tone and an oscilloscope for precise gain matching.
5.2 Crossover and Subsonic Filter Adjustment
- LO-PASS X-OVER: Adjust this filter to match the frequency response of your subwoofer and the rest of your audio system. A common starting point is 80 Hz.
- SUB-SONIC: Set the subsonic filter slightly below the tuning frequency of your ported subwoofer enclosure (if applicable) or around 25-30 Hz for sealed enclosures to protect the subwoofer from damaging ultra-low frequencies.
5.3 KickEQ+ Tuning
The KickEQ+ allows you to boost specific bass frequencies. Use it sparingly to enhance bass without introducing distortion.
- naekeun: Start with 0 dB boost and increase gradually.
- CENTER FREQ: Experiment with different frequencies to find the one that best enhances your subwoofer's output in your vehicle.
- BANDWIDTH: Adjust the width of the boost. A narrower bandwidth (higher Q) will affect a smaller range of frequencies, while a wider bandwidth (lower Q) will affect a broader range.
