Why is my JBL Speaker System humming or buzzing?
- JJames BowenSep 8, 2025
A hum or buzz in your JBL Speaker System can stem from several causes: * Improper A/C grounding or ground loops: Try 'lifting' the audio ground using an XLR/F to XLR/M adapter on one end or re-routing audio cables away from AC power and lighting cables. * Excessively long unbalanced cable run: Use the balanced outputs (if available) of your mixer or source equipment to drive your SRX800 speakers, or use a DI (direct injection) box to convert your unbalanced equipment output to a balanced output. * Improper system gain structure: Reduce the INPUT level controls and increase the output level of your source devices.
