How to Filter Noise in the XLR Connector to RCA Connectors
Common noise problems in a sound system, such as hissing and humming, can be caused by old or dirty audio connectors. When you clean audio connectors, it is important to have the proper cleaner. Audio connector cleaners, such as Kontact, DeoxIT, and basic rubbing alcohol, can be used to clean audio connectors as well as restore sound quality. XLR connectors, most commonly used for microphones, must be cleaned to ensure clear and crisp detailed recordings. When you connect an XLR connector to an RCA connector, it is important that both metal sides be 99 percent sterile in order to achieve the best recordings.
