The soft hiss that you are hearing from both speakers of your Sherwood RD-6505 may be caused by a few different factors:
- Ground loop: A ground loop occurs when there are two or more devices connected to a common ground, causing a voltage difference between the grounds. This voltage difference can create interference, resulting in a hissing sound.
- Faulty cable or connection: Check all of the connections and cables between your audio source and the Sherwood RD-6505. Make sure that they are plugged in securely and that the cables are in good condition. A faulty cable or connection can create interference and result in a hissing sound.
- Amplifier issue: The hissing sound may also be caused by an issue with the amplifier circuitry in the Sherwood RD-6505. If this is the case, you may need to take the device to a professional for repair.
- Power issue: If the power supply of the Sherwood RD-6505 is unstable, it can also result in a hissing sound. Check the power supply and ensure that it is providing the appropriate voltage.
If you have checked all of these potential causes and are still experiencing the hissing sound, it may be best to contact a professional for further diagnosis and repair.
