Yamaha DSP A1000 - Shut off Problem (1 Viewer)

[bigredjon]

Hey guys,

So I have never posted on this forum before, but have used it a lot as a reference point for home audio problems. Recently, I purchased a Yamaha DSP A1000 (older model, probably early 90s but one of the pioneers in surround sound) and it played fine when the person I bought it from played it for me. I got it home, hooked it up to my ipod and some Klipsch KG4 speakers, and it worked for about 10 min. before shutting off. Now, every time I try to turn on the amp/receiver it shuts off within about 3 seconds. Every attempt to change this has resulted in failure. I am sure this has something to do with the 6 ohm min amp being hooked up to the 4 ohm speakers, but find it strange as the guy I bought them from has owned them for about 15 years and never had a problem. Is there a way to disable this protection system or is it good that it is enabled? I'm hoping to avoid a repair shop as it can get costly quickly, and I already spent $300 on the amp, 2 KG4 speakers, and a Carver CT-7 Tuner.

Let me know if any of you have seen or heard of this before.

Thanks!
Jon

Just a note, the amp clicks before it shuts off in about 3 seconds, and there is nothing hooked up to it, and I have tried different outlets...

I would make sure there are no frayed wires on the amp or speakers that are touching each other. Are you driving it loud? Even if the Klipsch are 4 ohm, they are so sensitive I wouldn't expect it to be a problem.

The amp shuts down when nothing is connected to it...
