R-112SW Randomly Shuts Off

Hi,

 

I bought an R-112SW last August and it's been working great. After a while, the auto power-on function stopped working. My A/V receiver is Yamaha RX-A2040 and I haven't  changed any settings. I settled for 'always-on' but now even when I put the switch to 'ON', it randomly shuts off and won't power back on unless I pull the power plug, wait a couple of seconds and connect the plug again. Without pulling the power plug, the power switch has no effect.  It behaves like a crashed computer or something that needs a cold power reboot. 

 

I have two subwoofers connected to the receiver and the other one (Yamaha SW-315) works just fine.

 

At first I thought something might be goingg wrong when the power-saving function kicks in (I know that's not supposed to work in the always-on mode), but it went dead while I was watching a bass-rich action movie today.

 

Sometimes it works just fine for hours, other times it shuts off in half an hour. 

 

Any thoughts?

Just leave it on. It doesn't use any more current than auto.

Unfortunately, leaving it on doesn't solve the problem. It eventually shuts down and I can't get it to wake up without first cutting the power. Whether I leave the switch to 'On' or 'Auto' doesn't make any difference. As suggested, I guess the amp board is faulty. But it's weird that the amp gets to work again, albeit for a while, when the power is reconnected :-(

 

While googling, I found several similar (almost exact) complaints with R-112SW.

 

Even in South Korea where I live. What's the odds? It indicates some sort of a design flaw or crappy parts.

 

I want to return the unit but the local reseller won't take it back. Guess I'll have to send it in for repair instead.

The other option is to buy and external amp  similar watt, RMS/Peak and use it to power the sub.  This may be a cheaper fix.

how would this be cheaper on a sub under warranty for another 4 years?

Shipping cost alone will buy an amp.  He also said the local reseller won't take it back.  Not a lot of good options left.

i would assume if bought from a authorized dealer over there that they will just send him a new amp same as here in the states. its free. 

I would assume your assumption is incorrect.  Looks like he bought it from a reseller, not authorized dealer.

Eventually, I ended up taking the unit to the authorized dealer affiliated to the reseller I mentioned. 

 

They'll be testing it and request necessary parts from Klipsch, the whole process should take 2-3 weeks, they say.

 

 Just hope everything will turn out fine after all the hassle.

Hi Guys,

Sorry to hijack the thread, but wont post the same issue in the forum.

I bought my R-112sw this past May. like 4 months old and the same issues started happening yesterday watching X-Man Apocalypse 4k.:angry: The different is that mine wont hold on more than 5-10 min in either auto on or always on. Doesn't even matter if it is driving or just on without any cable. I left it unplug all night to hopefully discharge or something but no luck. I got mine from acousticsounddesign.com an authorize dealer. Either way I know I need to call klipsch on Monday to start a warranty replacement or fix. My question is, will the replacement unit have the same problem over time? Or they upgraded. Was thinking to get a 3rd sub but I guess wont be Klipsch. Thanks

I tied so many options this morning and the only think changed was the time that held on, but didn't past from 10min.

Per your suggestion I dont think it is like it over heating and going to self protection mode; Because I just powered on without the LFE cable from the AVR and 0 gain and it did shutted off after a couple of min. Back amp plate was cold. Can't find a logic pattern and I haven't change any gain on the AVR to cause this.:(

How do I connect an external amp to the R-112SW? There is only LFE port, white RCA, Right Red RCA and WA Port.

Can I use another AVR amp for that? 

 

You would not use the plate amp at all, don't even plug it in.

 

Open up the sub and unhook the connectors that attach to the sub driver's +/-.  An external amp (not AVR) such as an Inuke 3000 would then bypass the plate amp connecting directly to the sub drivers.
