What does it mean when my amp is on but there’s no sound?

When your amplifier is powered on but not producing any sound, it generally indicates a disruption in the audio signal path. This could result from various issues, such as a problem with your audio source, connectivity issues, or settings on the amplifier itself. The fact that the amp is on shows it’s receiving power; however, the absence of sound suggests that the amp isn’t amplifying any audio signal to your speakers.

It’s essential to troubleshoot each component in your audio chain, starting from the source (like a guitar, computer, or streaming device) to the amp and then to the speakers. Any disconnection or malfunction along the way could lead to a situation where the amplifier is active but silent.

How can I check if my audio source is working correctly?

To check if your audio source is functioning properly, start by ensuring it is powered on and properly connected to the amplifier using the correct cables. If you’re using a device like a guitar or a computer, try playing sound or sending audio from the source. If possible, connect the source to another amp or speaker setup to verify that it produces sound correctly.
