If you jump on the Yamaha web site you can download the manual which will show you how to connect the speaker system. Hope this helps.

Have you looked at the manual? How did it fare using the set up test tones? Did you assign the digital inputs?


The unnamed sources probably have manuals, too.

Generally speaking, an amp protects 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 'naked'. 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.

Check for loose speaker connections at the speaker as a root cause for intermittent shutdown.

The manual mentions the setting of the speaker impedance being incorrect. Consider that.

... and exposure to strong electrical shock or static. It's winter and dry where I am so I'm always zapping myself when I touch something. Food for thought.

IT sounds like you have bad solder joints in the audio output stage that need to be retouched to fix the problem.
