What errore code f61 means on technics sa eh750 amplificator?


Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it '*****'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

I have got the technics SH-EH550 UNIT, but i want to utilise the suround sound functions of the SH-EH750 unit on my system. is it just a case of unplug the EH550 unit and replace that with the EH750 unit...


Hi,
As you stated technics SH-EH550 UNIT can be replaced with SH-EH750 unit ,
Since this unit has the main power Amplifier with suround sound functions in it,you do not need the other units unless you do not plan to use..

Hope this helps!..if more help requires pls let me know.
