Be sure that the EQ settings aren't accidentally putting you over the top as far as demand is concerned. Bass-heavy material? Same conditions apply...accordianman

    I believe you have bass and treble controls,no? That would be your EQ settings...accordianman

I had the same problem. What I did was hard wire the fan so it runs whenever the unit is on. I had the reciever set for low impedance, when I turned this off all works fine. (Low impedance is only for speakers with an impedance of 6 to 8 homs or less)

Its it's a Panasonic receiver sa - xr15 it keeps on saying it's overloaded and I got nothing hooked up to it right now


It might be down to the fact that the main power amp has shorted and therefore overloading the system. It can happen if say you had some faulty speaker cable, or two wires touched together. Or it can happen on it's own.

Tip

Keeping your SA-DA8 cool


When I first bought this I noticed that it runs very hot even on low volume levels. I took it in for repair and told the tech that the fan didn't come on even when hot. He said "works as designed - the fan is output-power-driven, not temperature driven."

Wishing to prolong the life of ma SA-DA8, I used an old computer power supply and muffin fan. Plugged the PS into the controlled AC output of the amp, and the fan into the PS. Jumpered the "power-on" pins of the PS. Laid the fan on top of the amp, padded with some foam tape, and it now stays a lot cooler (and the fan is very quiet, though not silent.)

Overload sa-tx50


Most overloads are caused by the main output devices. They will go short circuit if for example speaker wires have come into touch. Another cause is high volume or a faulty speaker. Or poor ventilation around the amp causing excess heat.
The only cure is to replace the device(s) generally located on the heat sink.

My amp says overload whenever i plug speakers in to it. its a Technics SA-DA20


Check your wiring. Make certain there's no breaks and the two parts of the cable do not touch each other.
If it still says the same with good wiring you have probably developed a fault in the main amp. A failed transistor etc, located on the big heat sink.

My Technics sa GX350 tuner keeps going into overload. It's the only thing plugged in.


Hi mate, had the same problem with my amp.. Take the top off and there is a fan at the back, there are 2 piece's of copper flat wire that touch together and these do not touch anymore so when its turned up or the bass gets stronger it cuts off as the fan should kick in at this point. If you can get these to touch again (bend them) then the problem will be gone!! I have had to do this a few times now though so this is not a long term fix.. I may try soldering!
