Hey

I was watching Breaking Bad for the second time last night and my NR-3030 just turned itself off and then on again. I had been watching for about 3 hrs with a short break about the 2.5 hour mark. My projector and Apple 4k TV are on the same power point and didn't cut out, so it wasn't a power issue. I have 7.2.4 set up and volume was set at 54 at the time.

The NR-3030 sits on top of a cabnet so good ventilation.

Any thoughts on preventative maintenance?

Am I pushing it too hard running 7.2.4?

It has cooling fans and heat sinks but should I be looking at additional external cooling? 

Anyone else had this issue on a similar model. I know older Onkyos had HDMI board heating problems but I wasn't expecting it on this model.

What volume were you running, what speakers and what is your crossover set to? These will all affect how much heat is being generated.

I have no reference point/nothing to compare to, to say if its running hot or not. I can put my hand on top of amp with no issue.

You have got me thinking though. The crossovers are probably set too low when I consider the crossover points on each speaker. Especially the Fostex fronts and Jamo Centre. I need to get the subs to work a bit harder. 

 

I have mix of 8 and 6 ohm speakers and have the impedance on the NR-3030 set to 6ohms. Is that correct?

 

Crossovers set to 80khz all round.

FRONTS - Fostex FE103NVs tapered horns - 8ohm/88db

CENTRE - Jamo E6cen 6ohm ?db

SIDES - Jamo 7.4s 6ohm ?db

REARS - Fostex FE83 Spiral horns 8ohm 87db

IN-CEILING -  I will have to check.

Those speakers aren't too hard to drive and 80Hz crossover is fine.

 

Setting the impedance on the NR-3030 to 6 Ohm will throttle the power, but in theory reduce the chance of overheating. In practice you may find that setting the impedance to 8 Ohm gives enough headroom to avoid cut-outs.

I think I can only set the NR-3030 impedance to 4 or 6 ohms. I was a bit surprised when I first saw this.

OK, that's uncommon, but...

Same.

. It may be a coincidence but this has only happened since changing impedance to 6ohms and setting all crossovers to 80khz. I will experiment and report back
