4.2 Setting up your Eris Subwoofer for Best Performance
1. Use balanced cables to when physically connecting your subwoofer to your audio
device. A balanced cable is a type of audio cable that uses three conductors (two signal
conductors and a ground conductor) to transmit audio signals. Balanced cables help
to cancel out any noise or interference picked up along the cable length. Unbalanced
cables are more susceptible to noise and interference and should be avoided.
2. Make sure that your subwoofer is plugged into a good power source.
Unstable or noisy power sources can cause unwanted noise in your audio
signal. Use a surge protector or power conditioner if necessary.
3. Keep your cables away from power sources and other electronic devices to avoid electromagnetic
interference that can cause buzzing, humming, or other noise in your audio signal.
4. Position your subwoofer correctly to minimize noise. Keep them at a reasonable
distance from other electronic devices to avoid interference.
5. Proper gain staging can help you avoid noise in your audio signal. Gain staging
refers to the process of setting the input and output levels of audio signals in a
recording or mixing system to achieve optimal sound quality and avoid distortion.
Make sure that your input levels are not too low or too high. Keep your levels within
a reasonable range and avoid overdriving your audio interface or mixer.
