There is a defect in the final amplification stage of the receiver. This may have been caused by a short in the speaker wires. The typical defective parts are the output transistors. Expect a parts cost in the $40 range for this repair. Any audio service shop should be able to repair this.

SOURCE: I get a message

Page 59 of the manual (avaliable at retrevo.com after you register)...

"PROTECTOR/CHECK CODE 11
Irregular current is output from the speakers. Turn off the receiver , check the speaker conenction and turn on power again"

What this means is it senses a short circuit in one or more of the speaker paths. Disconnect all speakers, see if it works with none; then start connecting speakers again until you find the problem.

Please advise if I can fix myself ? or do I need to take some where and if yes where and who can I trust


Can you please tell me exactly how you have the receiver wired. What I need is, for example, the left front speaker is wired to what? Do you have more than one speaker wired to to the same speaker terminal? For more information, or if you would like to inquire about having your Sony repaired, please visit my website at audioserviceclinic.com. By the way, I was a Sony Factory Authorized Service Center for over 30 years. Thank you.

I have tried too hook up my Gemini XL-500, to a Sony Digital Audio DTS discrete 6ch Amp , but get very low volume, tuner & cd dvd, volume is fine, does this have anything to do with the ground?...


No! The amp must have a magnetic cartridge pre-amp to increase the sound level. If it has one it will say "phono" on the inputs on the back and have a "turntable" - or "Phono" selector switch. If it doesn't have one (many new surround amps don't) you won't be able to play it properly untill you get a "magnetic cartridge pre-amp". This will make the signal loud enough to be used on a normal aux imput of the Sony.

Amp repair


Check all your connections to make sure wiring is correct, if the light stays red you have an internal fault in the amp.

MySony str-da5000es is showing error code 11 and shut off by itself after few seconds.check and disconnect all speakers, unplugged power from wall and still showing error 11. am missing something in here...


error code 11 (protector) - According to the manual, 11/PROTECTOR means, "Irregular current is output from the speakers. Turn of the receiver, check the speaker connection and turn on the power again." Most likely, a strand of speaker wire is shorted to the chassis at one of the speaker terminals.
Hope this helps !
