Onkyo TX-NR818 "official" owner's thread discussion - Page 193

post #5761 of 9514
I have a strange issue, when its quite in the room (late night) and I low volume to 0 or just don’t play music I hear strange hum noise coming from inside of the receiver, (not from speakers!) when I power off the receiver the noise is gone.
What could it be, very strange and annoying? Any thoughts ?
post #5762 of 9514
Hum, not hiss? Disconnect everything except the power cord from the receiver. Is the humming still there?
post #5763 of 9514
No , its Hum and its quite low frequency, I didn't disconnected the cables yet , but ill come from work and will do it.
Its interesting what it could be?
its coming from inside and i checked, it's not the fans!
post #5764 of 9514
Could be mechanical hum from the transformer.
post #5765 of 9514
You think its warranty case?
post #5766 of 9514
Not necessarily. Could be DC offset on your power line.

Looks like the 818 has dropped $80.00 in price to $699.00 at A4Less , for a refurb. Last week when I looked it was at $779.00.

Time to buy?? rolleyes.gif

I'd use XT32 without the Anti-Mode.
Ok, thanks alot for the info.

Good day all ,

I was wondering if you can help me out. I have an Oppo -BDP93 connected to the TX-NR818. I was wondering which o the 2 i should i leave the video decoding to ?

I'd use the AV since it effects all inputs. Give both a try.

I see that the tx-nr929 is available for wholesale purchase in the US... Did anyone know about an 929 ?
post #5774 of 9514
I have just encountered a sound drop off for a couple of seconds while playing flacs from my NAS through my media player (Dune smart B1) and feeding the receiver via HDMI. I thought that this was resolved with the latest firmware but it seems not. Usually I play the files on the NAS straight on the AVR via ethernet and I had mentioned no problem so far after the update.

I posted here about it a day or two ago. No info on it as of yet.

There are two waves already announced:
525 and 626 in April, 727 in May.

828 and 929 will likely be in June-July. Longer if there are any delays like last year.

OK, I have full local root access to any Onkyo receiver (though tested only on my 609). It should work on any Onkyo from 2009 to now.

If anyone wants to know how to do a tethered "rooting" of the receiver, let me know. As I mentioned earlier, the untethered method is a security problem and Onkyo has been notified of it.

This method required some basic electronic knowledge, some soldering skills (but no soldering on the receiver) to make the "jig" to connect to the receiver. You also need a serial device to talk to the receiver. I am using the Bus Pirate to do this since it understands TTL-level RS232.

*If* you do decide to do this, consider your warranty void. You can also easily brick the receiver if you do not know what you are doing. If anyone is familiar with ARM and embedded development with linux, you should feel right at home with this. It's also possible that a firmware update released anytime after today will lock you back out.

the 24fps fix firmware is OK.

Just so you know.

5.1 Operation

Front L & R, Center & Surround L & R are driven via the receiver amplifiers.

7.1 Operation

Front L & R, Center & Surround L & R are driven via the receiver amplifiers with the option of adding only 1 more of the following that will also be driven via the receiver (Front High or Front Wide or Rear Surround).

9.1 Operation

Front L & R, Center & Surround L & R are driven via the receiver amplifiers with the option of adding only 2 of the following with only one being driven via the receiver and the other requiring an external amp for the other (Front High or Front Wide or Rear Surround). The receiver is not capable of outputting all 3 at any one time.

9.1 Additional channel Configuration

A)SB Channels Driven by the receiver FH Channels Driven by an external Amp

B)SB Channels Driven by the receiver FW Channels Driven by an external Amp



I have mine set up 9.2 front L/R, center, Surround L/R, Surround Back L/R, then I use the EXT AMP For front highs. I love the way it sounds

For setting up 9.1, is it better to hook up the FH's or SB's to the external amp?
post #5778 of 9514
I guess I messed up the "quote" feature. ^^^ I asked about the external amp! redface.gif

I have mine hooked up 7.2 Front L/R Center Surround L/R SURROUND BACK L/R using the 818 then I'm recycling my old DEMON AVR-1905 using it for now as an external amp to run front highs, now I'm running 9.2.
9 channels and two subs.
post #5780 of 9514
The new 727 I'm not seeing the benefits no pre outs is that correct the only thing I see is it passes through 4K so I think I'll wait awhile to upgrade I just got the 818

Just so you know.

So tell me again why you would want to do this? I'm not in the market to brick my receiver.

Then don't.

I work constantly with iOS apps and iOS development and I have had no need to jailbreak any of my devices - even though I could. I'm sure 99.9% of people wont bother unless someone comes out with some great thing to do with it. So if you are asking "what does it do for me?" and you have no immediate answer, then you should not do it.

Your right 99.9% of us have no interest in trying to hack into the receiver I'm still trying to figure out how to get the plastic off the speaker wires LOL mad.gifeek.gif

Actually, you are quite right. I'll keep quiet about it here or take it to another thread.

Have you tried hooking the surround backs to the Denon? I'm just wondering if there is any benefit to rears or highs to the external amp!

Thanks!

Truthfully I chose the front highs to be on the ext amp because I'm going to use my high speakers to switch back and forth between highs OR wides. It seems to me I'm liking the highs it just SEEMS to fill the front of the room when listening to 5.1DD From directv. To me the backs only seems to be useful when I'm play a 3D blu-ray or blu-ray's that have 7.1 or master audio or DTS HD.

Anyone ever order their Onkyo or any other devices from here with good results?

I beg to differ. I've been quiet about single user flooding the thread with his audyssey problem, even though I believe it was mostly irrelevant to most readers (I think only few could understand it on technical level).
So I don't think that that single message a week or so with summary of your progress could do any harm.
While I'm not ready to root my AVR just for the sake of it, I'm really interested what makes it tick.
Please please please keep us updated.

For me one good reason to root AVR would be ability to send custom CEC codes to control connected devices. I'm hopeful that there is some sort of config file that translates commands received on rs232 or network into commands sent via CEC.
