Hi everybody!
Now the fun begins smile.gif

I have MA5000i amp and I wonder how the fan schould work and I suspect I have some problem here.

I have notice tha the bigger fan is not spinning at all, not even when I power the amp ON, but the smaller fan seems to work. The amp isin't hot at all and I don't have any fault error message from the amp. How can I see the error report in the system architect???

I would like to know how the fan schould work in normal situation.

Very important to know because I still have warranty, maybe it was so from the start.

Thanks

Hi again

The fans is working by the way. Had to look further in too see it spinning laugh.gif

But I still have a problem sad.gif . I have some noise when the fans is just to begin to speed up. One can hear it thru the speakers, some crakling noise.

Any ideas.

Anyway, decided to return the unit for inspection. Still under warranty.

Thanks

Hi
I have made a video of the problem.

Maybe this will help.

My amp is on the way to the dealer, some feedback would be nice.

Thanks for the excellent video.  Assuming you had no inputs connected to the amp?  We haven't seen this problem before, so sending it in for service or exchange is the way to go.

Hi
Bad News, same problem as before. Is there any possibility that it can be the PIP-network card where you connect the ethernet cable???? Can't find the proper model name that is installed in MA5000i.

The funny thing is when I tap the chassi relativly hard the fan start running and then I see the meters start jumping on Channel 1. Also, in Amplifier Setting in SA there is a Auto Stand-by mode settings and when I mix with the Threshold and Turn-off delay then things start to happen. If I set the Turn-off delay at 0 minutes and the Threshold is set at -80 dB and then slide the levelmeters between 0 to +20 dB the noice start to come from the subwoofers, as shown in the video in previos post.

Sensitivity is set at 26dB and y-linked but as I have mentioned before it is same fhenomena when I don't have anything connected, only power cable and the ethernet cable.

Didin't get any more info from service department, only some solder problem.

The unit is return to service again.  sad.gif
Thanks

Gosh, that really sucks, sorry you are having so much trouble.  The auto-standby feature shuts down the output stage automatically after a short time of idle audio.  So it sounds like when you defeat auto standby in SA or by tapping on the chassis, the output stage wakes up and begins passing the noise.  Unfortunately that doesn't narrow down the problem because the output stage is of course the last thing in the signal path.

There isn't a PIP module in this unit; the communication board is integrated.

You're not in the USA, right?  Just checking; I am wondering who is looking at this amp.

Ok I understand.

Is it ok that I give you a call by phone or email to explain the problem little further. I am not from US.

Thanks
