Couch Amp FAQ

Does Couch Amp need an account or cloud service?

No. The app talks directly to your receiver over your own network. Nothing leaves your LAN.

The scan doesn’t find my receiver

Check that it’s powered (or in network standby), on the same network, and that External Control is On — Setup → Network Settings on current models, Setup → Install Setup on older ES models. You can always enter the IP address manually.

Which receivers are supported?

See the support matrix. Short version: modern ES receivers (STR-AZ / AN series, and the STR-DN1080) get the full feature set; classic STR-DA and STR-ZA models get power, volume, inputs, and zones.

The app changed my receiver’s input names!

Only if you asked it to — the input editor writes names, icons, and show/hide settings to the receiver itself, the same way its web setup page does.

Is Couch Amp affiliated with Sony?

No. Couch Amp is an independent app. Sony, ES, and model names are trademarks of their respective owners, used only to describe compatibility.
