Thanks, that's a great explanation.
Now back to our regular scheduled programming.....

My son, who has much better high frequency hearing than me, being in his mid-thirties, reports that my AVP emits a high pitched whine when in standby mode but a much louder and (to him) disturbing noise when on. Given that I cannot hear it but he can, I would estimate it must be around 13-18 kHz. The noise is not through the speakers but a direct noise from some part of the circuitry. Can anyone cast any light on what might be responsible and whether it might imply an imminent circuit failure. We have definitely isolated it to the AVP.

I have heard this once (but was louder in 1 ch). I power cycle the AVP and everything was fine. You might want to try that.

Sorry to report that this is probably the fan that is mounted onto of the video (realta) chip. Not much you can do about it unless you want to change the fan. It might be turned off in pure-direct mode (after a while) but i doubt it.

There is 1 fan (this one) in the avp, and 5 fans in the POA. but the ones in the POA are normally turned off and controlled by volume and temp.

Having found a means of measuring the noise I can confirm it is a 13 kHz peak which moves to a lower level 15 kHz when switched to standby.

Any new to know the upgraded version of the AVP sell on the street ? Can,t wait any longer to play a full 11.2 configuration on my system anymore !

Onkyo just annouced their new Flagship Pre/Pro-

http://www.uk.onkyo.com/en/products/...509-58251.html

Looking at the connections on the back of it I would rather still go with the AVP-A1HD with its Hardware upgrade in October.

And its only 9.2 Preout instead of 11.2 preouts. Be interesting to see what Denon do in regards to this with the Hardware upgrade.

I noticed it supports 4K ( nothing out as yet ! ) but i wonder if that's signs of things to come.

yeah well prior to getting the avp, i did consider the onkyo / integras. but given how long I have had the avp and been what 3 models onkyo integras have brought in that time am very glad bypassed them and went for the avp instead. otherwise would be still stuck on the upgrade merry go around every year onkyo/integra seem to bring out a new model !

and which ever way look at it, whether putting the onkyo in integra clothing it just doesnt have the panache of the flagship denons sorry

So I guess we might have to replace our BD library with 4k BD's ( if it and when it comes available )

I dont think 4K is supported by BD, though happy to be corrected. also 4K is imax. so unless watching imax material and on a imax sized setup probably a bit nonsensical in the home.

but yeah wont stop the oems to introduce to give people cause to upgrade !

4K will also benefit for CIH. But im happy with 1080P and Im sure the prices of 4K projector will be high ( They will come down but not straight away. )

have a read of a bit of this frank,
http://magazine.creativecow.net/arti...ture-of-pixels

gives a little insight as to 2k / 4k. you'll see even imax is not even 4K. so where is 4K material going to even come from ?

the truth is we are not really even fully utilising BD ability now. so while oem quite happy to create buzz re 4K its all nothing more than a bit of hype I reckon.

4K BD media. I wish too, & that it will form part of the Denon board upgrade, but...Although the BD capacity is there, the demand is not here. Yet the Japs love the HD+ uptake domestically & here it has to be $99 BD players from JB for HP interest free to move the uptake! The whole HD & HD+ saga has been nothing but a pain in the proverbials. Whether it's national/international DBTV standards, BD vs HD-DVD, BD-3D, BD+. Remember DVD SuperBit? I have a few of these rarities. The 5th element was a ripper for its time. Doesn't it p*** you off that the primary Freeview channels in Aus have been downgraded? Even their secondary HD channels are compromised & yet there was supposed to be regulatory enforcement. We watched minimalist content for a decade & now its going backwards again. It all has to do with the cost of advertising production, the make-up dept & the old wood behind the news desk, I say. Bring in some new skirt I say. Give the young talent a go. Has nothing to do with station tech as they have invested heavily. You only have to see what they have slung on their shoulders at the Australian Open. How many of you early adopters subscribed to new gear like 1st gen HD STB & widescreen back in 2000 for the games? Disappointed by the 4:3 broadcast eh? Probably have to wait another decade until its right here. Anyway off topic. No mention of it in the Denon upgrade, so I doubt it somehow...Would be a good surprise though. It's in the HDMI 1.4a spec if I recall...

re CIH frank, it they just amended the BD format to include true anamorphic support. just as they had with DVD.

at the moment scope is constrained with 16:9 nature of the BD format,

allow scope to use full height of BD format utilising anamorphic image and that would be a greater step forward than 4K in my opinion.

I was meaning for people that wanted to do CIH without the lens and using the zoom function. We have certainly taken this thread OT.

I don't know if I can hear 15khz or not, I've never noticed that from my unit.
But if I stick my ear up to it I can hear the fan kick in when I turn it on and it doesn't shut down in Pure Direct, it seems to be much lower than 15khz though.
I can't hear it from more than a foot away and wouldn't have even know it was there if it hadn't been mentioned above.
rnrgagne's Avatar rnrgagne 08:16 AM 08-23-2011
As far as the AVP is concerned, 4k-schmore-k .... who cares lol. This unit is about audio IMO. It's no different than 3D, if I wanted it I'd get something like the Oppo with dual outputs and bypass the AVP with the video signal.

Yeah the fan made the most sense to me since that was the only thing i would suspect in this case. Now that he states its that high in freq. i wonder if thats it since it also seems way lower to me. Guess best to ask someone at denon might also be in its power units that would be my second guess .

Unfortunately, there isn't the luxury of being able to get just any source with dual HDMI outputs (fortunately, the Oppo is one of the best options) and dealing with dual HDMI outputs from multiple sources could quickly turn into a PITA. If 4k becomes "important" in the relatively near future, I'd be more interested in being able to pass it through the AVP than worrying about the AVP actually processing it - same as what I do with 1080p. The AVP's OSD would be the only real issue when watching a 4k source.

How about the new Lexicon? 16 channels. And a price to match.

Have they finally officially announced that thing yet? I'd normally check SMR-Forums, but it looks like someone forgot to pay the bill for their web hosting...

It would probably be a bit too weird to go back to Lexicon though .

After my recent experiences with Harman Kardon's parts department, I will never consider any piece of HK (or its brands) gear again. It was a literal nightmare dealing with them. Lexicon and Revel are their uber premium brands but we still have to deal with the same parts and service personnel who are CLUELESS. I am so glad I switched to buying Denon.
