I have "protect" flashing on my TEAC theater receiver AG-V8525. I need to know how to fix or how to get a manual

You could try searching on on google

Hi. Unfortunately the protection circuit is saving your speakers from a fault, most likely one side of the amplifier in the unit is defective.

This needs an engineer.

Service manual is here if you need it. TEAC AG H500 Manual AM FM Stereo Receiver HiFi Engine

It would have helped to know something morwe about the 'active' speaker.I imagine its manual would tell you what it needs for input.

Active speakers are usually designed to be driven by volume-controlled Line Level inputs. This receiver has none except for the Subwoofer PRE Output.

use a search engine (I used Google)

"Teac AG-D9320 manual"

retrevo.com has the link

You have to type alpha-numeric gibberish verbatim or there will be no good information coming back.

If you mean TEAC AG-V1200 then just google it.

Here's a manual for $10 http://www.teac.owner-manuals.com/AGV1200-owners-manual-TEAC.html

It probably has the specs.

This seller claims 110 watts per channel all around, which sounds supsiciously generous. Rear channels don't need that kind of horsepower.

Protect on any reciever usually means that it has reached its maximum capacity of volume (known as clipping) and at the reciever is now automatically reducing the volume to avoid damage. This some times is triggered if the reciever was used hard and is now damaged so you would need to bring it to a repair shop. Sometimes its caused by a bad wire to the speakers, a short to say. Check all your wiring, make sure its not overheating and getting plenty of air. Some where its recieving a signal telling it to go into protect mode.
