Hi,
Well, if the system does turns on, it could be just an OPAMP its one of various little 8-pin ic's that are in the pre-amp section that got fried, STAGEPASS YAMAHA Powered mixers runs with a switchmode power supply, if the power amp section has any problem the power supply does not turn on, if you can add further details like if it does turn on, the green light turns on, do you hear something in the speakers, the more the info the best i can help you.

Paul.

SOURCE: I had major static sounds from my yamaha stagepas

Chances are there is nothing wrong with the mixer. IF you accidentally turned on Phantom power, that would cause the problem. Phantom is ONLY used with condenser mics and a few DI boxes. Turning it on can create noise unless balanced lines are used everywhere.

Stagepas 300.Why does one of the mic volume controls, have to be at full level to hear anything through the speakers the others are OK ?


I would suspect the input jack on that channel is either bad or has a leg come loose from the circuit board.

Here you go:

Scroll down to "Get manual" on the webpage and click to download. IGNORE other download links. This is a class D amplifier and the switching power supplies run directly off the power line so as a qualified technician I am sure you know to use an isolation transformer while working on this for personal safety. I am GOING to make an educated guess at the problem... The circuitry has a surge limiting precharge for the input power filter with a thermistor that when power is almost up and circuits are balanced the thermistor is shorted out by a relay so that the high currents can be handled... I suspect that the thermistor has gone bad... now that can be due to a short in the rectifier filter combination OR even a failure in the switching power supply or lastly, just a part failure of the thermistor. Using an isolation transformer, ALSO put a 100 watt incandescent lamp in serie with the power input cord to act as a resetable fuse and current limiter while working on this. Let me know how it goes...

How can I obtain a plugin 100w module for my Stagepas 300 as both output transistors are short circuit plus several pcb mounted driver transistors/resistors damaged.Thank you David Bunn


You could try buying the part from Yamaha America... the music section in California. Transistors and resistors are easily replaceable so repair of the board would be the path I would take myself... but then I am an electrical engineer.
