- Live Sound Systems: Live sound systems can also benefit from subsonic filters, as they can help reduce low-frequency energy that can cause the speakers to become overworked.
How to Adjust Subsonic Filter
Adjusting the subsonic filter on your amplifier can be a bit tricky, but here are some general guidelines:
- Start by setting the subsonic filter to its minimum setting (usually around 20-30 Hz).
- Play some music with low-frequency content (such as bass-heavy electronic music).
- Adjust the subsonic filter until you find the optimal setting for your system.
Common Misconceptions About Subsonic on Amplifier
There are some common misconceptions about subsonic on amplifier that need to be addressed:
- Subsonic Filter Reduces Bass Response: This is a common misconception. The subsonic filter is designed to remove extremely low frequencies, not bass frequencies. In fact, the subsonic filter can help improve bass response by removing low-frequency energy that can cause the speakers to become muddy or boomy.
- Subsonic Filter is Only for Subwoofers: This is not true. The subsonic filter can be used with any type of speaker system, not just subwoofers.
Conclusion
In conclusion, the subsonic filter on amplifier is a powerful tool that can help improve sound quality, reduce distortion, and increase headroom. By understanding how the subsonic filter works and when to use it, you can take your audio system to the next level.
