How to eliminate hum on an analog input of my JBL Recording Equipment?
- JjphillipsSep 13, 2025
If there is hum on an analog input, ensure that all cables are making a good connection. If necessary, remove the cable from the connector and plug it fully in again (turn the power off before doing this). Verify that the connections inside the source cable connector are not broken or badly soldered. If the hum originates only when one particular source component is connected, ensure that an antenna cable, or satellite connection to this source is ground isolated. Contact your installation contractor.
