Why Does the Volume Change Between Different Audio Sources?

This week, a client reached out asking why the volume on their patio speakers sounded lower when watching TV compared to streaming music from Pandora or other apps.

This is a common question—and the answer lies in how different sources output audio.

Different Sources, Different Volume Levels

Every audio source (TV, music app, cable box, etc.) outputs sound at a different signal strength. Your amplifier—whether it's Sonos, Bose, or another brand—amplifies the signal it receives, so if the source signal is weaker, the resulting sound will also be quieter.

For example:

• If your TV’s output is set at 70% and your amplifier is set at 60%, you're getting 60% of a 70% signal.

• If Pandora is outputting at 90%, and the amp is still at 60%, you'll naturally hear a louder sound.

How to Fix It

• Adjust the volume at the source (TV, streaming device, app settings).

• Fine-tune the amplifier volume for each source if your setup allows it.

• The volume difference shouldn’t be drastic. If it is—and adjusting volume levels doesn’t help—it’s a good idea to check your cables and connections for issues or damage.
