Overload Signal Technics SAEX510: Causes and fixes

[tonytedrow]

Overload signal activates on my Technics SAEX510 receiver when in 3 stereo and Surround modes. Problem doesn't appear to be with any speaker. The 2 channel mode works fine, however. Can anyone offer some advice and/or insight to correct this. Thank you.

The receiver could be faulty, you will have to repair it.

First thing before doing anything, remove any dust inside the case.

Also check your cabling, any wires shorted? Maybe a speaker is faulty.

As mentioned about the first possibility is that one of the speaker wires or speakers is shorting. The overload is the receiver going into protection.
Disconnect one speaker at a time from the back of the receiver. When the problem goes away that speaker cable or speaker is the problem.
The other possibility is that the Dolby processing is being overloaded by too much input signal. When you switch to stereo the problem goes away because you are no longer using that processing. This is normal. You need to turn down the output of the source. If it has it's own volume control turn it down. You can turn the receiver volume up to compensate. They do make inline audio attenuators that can be connected to lower the volume of your source if needed.
