Harman Kardon AVR 247 issues and review
Just to let everyone know this audio problem I was having was with the receiver. I talked to Harman Kardon and the first unit had some glitches. They have since fixed these problems and are sending me a brand new unit that has the updated components and firmware. This is a fantastic AV receiver, but it just had to have the bugs worked out. HK's tech support is second to none, very friendly and extremely apologetic for the problems. The sound this receiver puts out is just awesome. Anyone looking for a new AV receiver should definetly consider the AVR 247 or it's big brother the AVR 347. I see alot of people talking about the new Onkyo's, but I think HK has superior sound. From what I understand there is no reason to have HDMI 1.3 (this is HDMI 1.2, same as the HD-A2). Any questions about this receiver, just ask.

Are the watts per channel sufficient? Is this model rated at 50 watts per channel?

impalass8 05-01-2007 01:26 PM

50 watts X 7 continuous, 85 watts X 7 peak. Yes the wattage is sufficient unless you want to blow your ear drums out. My theater is a room in my basement that is 30 feet wide and 20 feet deep, and when it's cranked up you have to yell to talk. HK is very conservative on there power ratings and the nice thing is when it is really loud it's still very clean sound (low distortion). Good speakers also make a difference. I'm using Sony 4 way towers for the fronts, Sony 12" 150 watt front firing sub, Polk Audio CSi3 center, and 4 Polk Audio R-15's for the side and rear surrounds (7.1 setup). If you are looking for more power check out the AVR 347, same as the AVR 247 except little more power and a few more inputs (same number of HDMI inputs though). If you looking for a great receiver I suggest checking out the Harman Kardon's. Great sound, good price. I paid $450.00 on sale at Best Buy, although it's not on sale at the present time. Hope this helps. Any other questions, just ask.

HK is also a true high current amp unlike the pioneers and sony's and such the wattage is true and is as stated generally rated lower than actual. The sound is clean and very good quality this reciever is HDMI1.2A as I have been informed as I was looking at the same reciever but I think I am now leaning towards the 347.

Does the AVR 247 take PCM?
I'm thinking of getting a PS3 to watch Blu-ray movies with. Will the 247 handle multi channel uncompressed PCM coming through the HDMI cable?

I do not believe it will but I have not looked into it that closely as I would never own a PS3 or any blu ray product for that fact but I do know for a fact it does heavily support DDTHD and DTSHD. It will do PCM in 32KHz and 44.1 KHz.

impalass8 05-11-2007 02:53 PM

According to the manual it will accept PCM at 32kHz, 44.1 kHz, 48 kHz, and 96 kHz. If this is uncompressed I do not know. I can tell you that I have my HD DVD player hooked up throuh HDMI for video and audio and when I play a movie it says on the display " Multi Channel PCM 48 kHz". I hope this helps.

billcat 05-11-2007 10:49 PM

Multichannel PCM
Thanks, I was looking through the manual and I wasn't sure it would work with multi channel PCM, I hope it does. I guess I'll have to just buy one soon. Hopefully it won't have the problems that the first poster experienced.

The problems with the AVR 247 were with the first production run only, unfortunately I got one of these units. I contacted HK about this and they were very friendly and appologetic. I had a brand new unit in 5 business days. Tech support told me these problems with the popping in the speakers and the improper handling of the LFE signal were all handled in firmware updates. They said it all had to do with HDMI connection issues. I can assure you that my new 247 works perfectly, no issues what so ever. They said all current units out there should be taken care of and all currently shipping models are fixed. Hope you like your AVR 247, I love mine.

Bought one but problem
I bought an AVR 247 at Fry's tonight. They gave me the sales price from Best Buy, $425.

Anyway, I was trying to connect it with SVideo to my old TV and I get nothing from monitor out. I get an image when I connect to Video1 Out. It's strange. Perhaps I'll call their tech support Wed. My sources are coming in with Svideo.

I haven't hooked up my HDMI stuff yet.


billcat 05-16-2007 07:49 AM

Problem solved
I called HK and was told to do a system reset. That fixed the problem.


impalass8 05-16-2007 01:36 PM

Hi billcat. Connect your AVR 247 to your tv with composite cables at first, then go into the setup menu and change the output resolution to 720p instead of 480p. This should output the signal correctly so you can use the S video. If this doesn't work then I have got it backwards. When I got mine I hooked it up with composite to (Standard yellow RCA cable) do the setup and when I changed the video output setting to 720 p I lost my picture. I started freaking out cause I thiught the receiver died. Then I started playing around and when I hooked the AVR 247 up to my TV with HDMI my picture showed back up. So play around with these settings a little. If your TV is like mine it has multiple inputs, I hooked up one S video from the 247and HDMI from the 247 at the same time after that just for setup purposes until I had everything configured. I then disconnected the S video and now I have one HDMI output to my TV. All my other video runs through the 247 except my cable TV and my VCR, which hook up directly to the TV because the up converter in the 247 did strange things to thes signals. The up converter in the 247 does an awesome job up converting my 480p Sony 5 disc DVD player, although I really have no use for this since I have an HD-A2 HD DVD player. Hope this helps. If you have any other questions I'll try to answer them, otherwise Harman Kardon's tech support is very friendly and very helpful. Good Luck and enjoy your AVR 247.

Will the HDMI pass 1080p signals? Also, checking the HK site....there they only claim the HDMI implementation on either model to be 1.1.



billcat 05-18-2007 02:02 PM

Claims to pass 1080p
They claim to pass 1080p and upscale to 720p. So far it seems to be working but I haven't used it much.


impalass8 05-18-2007 09:06 PM

The AVR 247 and 347 is HDMI 1.2a. I recieved this info from one of the Harman Kardon engineers directly. It does pass 1080i and 1080p straight through with no video processing. These recievers will take any 480i , 480 p, or 720p input and pass it through the HDMI as 720p. They also said it should work just fine with the PS3 which claims to be HDMI 1.3. Audio is also passed to the reciever through the HDMI cable and processed by the reciever as either Dolby, DTS, or PCM. The HDMI is not just a pass-through(swithching only) type as are alot of recievers in this price range. There are starting to be more coming that will do what the 247 and 347 do, but I believe Harman Kardon sound to be second to only extra high end components.
