20 Most Recent Sony STR-DE597 Receiver Questions & Answers


I've had a Sony STR-DE725 for years, and it's always worked fine, until recently. When I turn it on, instantly, or within 1 minute - it will "click" and then display "PROTECTION". Like any good DIY'er, I googled everything - so I looked for any loose speaker wires, and finding none - decided to open it up. I pulled it out on my workbench, opened up the case, and blew out about an inch of dust from everywhere with an air compressor. Next I disconnected and reconnected every connection that I could easily reach. Finally, I unscrewed (about 1/4 turn) and re-tightened every single screw that I could reach in the guts of the receiver. It works fine now! Go figure... probably the dust, or a loose connection somewhere. Definitely try this first, as you have nothing to lose but 30 minutes of your time on a weekend!

There's nothing more you can do. It is likely a shorted output transistor that became damaged when either playing too loud for too long, connected to shorten speaker wires, etc. A repair shop or replacement will be you best options.

The Jensen JS650 does not accept line level input so you need to use the Front B speaker output from your Sony receiver and not the RCA subwoofer output. Even though your subwoofer is active, it does not support line level (RCA) signals.

Just connect the subwoofer as you would a pair of speakers. Once connected, you make sure the front panel speaker switch on the Sony is set to A+B so you get sound from your existing speakers (A) and subwoofer (B).

I hope that works for you.

The reason you may find it difficult to connect the Sony Receiver to the Jensen JS650 is that the JS650 does not have a line level input (RCA) to match the RCA subwoofer output of the STR-DE597 receiver. In this case, all you need to do is connect an extra set of speaker wires from the "Speaker B" Left and Right speaker connections on the back of the Sony to the speaker input connectors on the Jensen. On the front panel of the Sony, select speakers A+B settings so that the subwoofer is on in parallel with the front speakers.

I hope this answer is helpful to your home system set up.
