How do you remove the hiss from speakers?

To remove hiss from speakers, first check for any loose connections and ensure that cables are securely plugged in. Adjusting the volume levels on both the source device and the speakers can help; lowering the source volume while increasing the speaker volume often reduces noise. Additionally, using a noise gate or a digital audio processor can effectively eliminate unwanted hiss. Finally, consider using high-quality cables and ensuring that your audio equipment is properly grounded to minimize interference.
