Any info on Harman Kardon AVR 347

post #1 of 52
Thread Starter 
I was doing some reasearch on Harman Kardon AVR 347, and cant really find any reviews on it. Just wondering if anybody has any new info on how this unit actually performs. Here are the stats for receiver:

With exceptional surround sound reproduction, XD Ready, and dual HDMIs, the Harman Kardon AVR-347 7 x 55W 7.1-Channel Home Theater Receiver will take your home theater experience to new heights. In the convenience of your own home, you can finally watch your favorite movies come alive with the AVR-347. It offers you the same surround sound entertainment value you would come to expect from a night out at the movies.

The AVR-347 features High-Current Amplification, Mutli-room Capability, iPod Connectivity, Component Video Switching, and Dolby Pro Logic decoding technology. In addition, Harmon Kardon includes its exclusive Logic 7 processing and Cirrus Logic 49400 Series DSP technology to create a wider, more enveloping surround-sound environment with enhanced sound transitions for pans and fly-overs. If you want a unified, stylish, and easy-to-set-up A/V home theater receiver, look no further, you won't find a better solution than the Harman Kardon AVR-347.




Key Features

7.1-Channel and Digital Audio Decoding
The AVR-347 uses specific Dolby Digital and DTS codecs to reproduce an enveloping 7.1-Channel surround sound experience. The unit encodes Dolby Digital, Dolby Digital EX, Dolby Pro Logic II, Dolby Pro Logic IIx, Dolby Virtual Speaker, Dolby Headphone, DTS, DTS 96/24, DTS Neo:6, DTS ES, Logic 7, and Cirrus Logic 49400 series DSP processing.

Logic 7 Processing
Originally developed for high-end processors, Logic 7 processing is packaged with the AVR-347. Proprietary digital algorithms are used to create a more cohesive and enveloping sound field from the tens of thousands of currently available analog matrix soundtracks. Logic 7 is capable of reproducing either five or seven channels of exquisite sound from your two-channel source.

High-Definition Multimedia Interface (HDMI)
The AVR-347 has an integrated digital HDMI processor capable of carrying digital audio and video information through a single cable. This technology enables the AVR-347 to reproduce the highest quality picture and clearest sound available.

Surround Mode Selection
The AVR-347 offers a wide choice of analog surround modes available for use with sources such as your CD player, VCR, and TV cable broadcasts.

EzSet Feature
With the push of a button and in a moment's time, your AVR-347 becomes fully calibrated to balance-out your home theater speaker system. Bottom line, the adjustment most critical to multi-channel movie soundtrack reproduction has been made virtually foolproof.

Upgradable System
If Harmon Kardon releases a software upgrade for the AVR-347 operating system at some time in the future, the upgrade will be possible through the RS-232 serial port.

Bridge Ready
The Bridge is a docking station (option) that enables connectivity from your iPod to the AVR-347's DMP connector input. Your iPod effectively becomes another Harmon Kardon component flowing through the AVR-347, and your iPod can be operated via the receiver's remote control.

High Current Capability
HCC is an overall design approach encompassing everything from transformer design and storage capacitor size to discrete output circuitry and minimal use of negative feedback. This enables the AVR-347 to combine tighter bass, superb transient response and enhanced presence at any volume level.

Advanced Processing
Most of the AVR-347's audio processing is handled automatically, with little intervention on your part. However, the AVR-347 is so advanced, it is capable of being customized to suite your particular system and your surround-sound tastes.

Built-In AM/FM/XM Tuner
Enjoy your favorite radio broadcasts with surround sound processing, with the built-in AM/FM wide-band tuner. Also, XM Satellite Radio reception is possible with an optional XM antenna module and subscription to XM service.

Easy Set-Up Feature
Harmon Kardon takes the guesswork out of the installation process with an easy-to-use connectivity color-coding system.

Not to threadjack, but that's pretty crappy that bh will charge your card immediately for placing a pre-order. I've got the 347 preordered for the same price through Amazon and I'm pretty sure JR doesn't charge until shipment either. On the OT, there still seems to be a bit of mystery about this unit, especially in how it differs from the less $$ 247. There were a couple of threads that were active yesterday if you do a search.

Here are the differences between the two as outlined by a forum member who talked to one of the tech's on the phone:

5 watts output difference
The 347 has 8 total digital inputs, the 247 has 6
The 347 has 3 assignable component inputs, the 247 has 2 unassignable component inputs
The 247 does have room eq
The 347 has A-Bus
The 347's remote is more elaborate

The 347 also has a higher level processor, which is why it can handle the EQ, and also some special Dolby game format (?).

Anyone know when it will release?

The information I received from HK may be incorrect. Comparing the manuals for the 347 and 247, the 247 manual states the unit has "3 assignable component video inputs".

FWIW I have been playing with this reciever for a two days now. I am a BB HT sup...
Its a great receiver, its clean and powerful. Im impressed as I own a 340, and a rotel 985.
I do like the idea of the Faroudja chip... havent tested it as we didnt hook it up for vid processing...
Its was busy today, so I didnt get to play with it as much as Id like.... soon I will though.

oh and not everyone at BB is a ******... there are some of us who dont suck

i bought this tonite.i also work at bb home theatre.i was very unsure whether to get his or the yamaha 661.if i dont like the hk,i can always return it.this is my first hk product and i have always loved the yammy.i will see tomorrow if the hk is all its cracked up to be.
post #15 of 52
I guess I'm third on the BBY employee list, and I'm a magnolia home theater senior. I plan to hook up the 347 to our demo tomorrow. My biggest concern is going from my htr 5960 and supposedly losing 20 watts/channel? I wonder if that will make a difference, especially w/ my klipsch rf-82 fronts (I use them for lows too because i live in an apartment and would get kicked out for sure if i had a sub). keep posting results if you get one setup please

Oh and P.S. we just have ours on the shelves turned on and they produce an ungodly amount of heat, even when not powering speakers, what gives?

we switched from the 5990 to the hk 247,and lost a lot of watts.but i didnt get to try it out,we were slammed my whole shift.

blah you didnt lose anything, you gained power....

we replaced a 5960 with the 347. HUGE difference. Other people from around the store were asking what the hell was replaced...

F3s, C2, S2s and two sub 12s... its fun at work
post #18 of 52
Is there any realy difference between the 347 and the 247 as far as video/audio processor chips?

The main difference seems to be in the multi-room capabilities/extra remote and the 5 watts of power. Would like to know if the processing capabilities are the same.

Thank you for any info/opinions on the relative merits of the 2 units. If I do not need the multi-room extras, is it still worth the extra $300.00 to get the 347 instead of the 247?

Regards,

Steve

I just compared 347 vs 247 from the manuals, does not look like any major difference. i would be going avr 247 instead of the onkyo 674 i was going to get. Hope there are 1080p flickering problems in this unit. Still going to wait for reviews then make the final decision.

You have 4 Hemis..
Just got back from MATS in Vegas, the Duster (440) ran a best ET of 9.5 and 137 Top Speed.. The SS/AH Cuda (426 Hemi) ran a best ET of 8.92 and top speed of 144. Not too bad considering the 3000' altitude of Vegas.. @ sea level the cars will be about 0.27 faster..

The Hemi puts out 1050HP which is about 300 more than the 440.. Both cars weigh in about 3300 LBs..
All things considered the 440 is easier to tune/run.. But both engines are in their 2nd season and have held up well but when the Hemi lites the tires up just hold on...

I have learned alot about Hemis over the last decade and fortunately had some of the best factory teachers like in Dick Landy.... RIP Dick..

Ok.

Now can someone actually tell us what we all really want to know, which is whether or not the PCM through HDMI actually works without any problems?

I also saw this on display at BB yesterday and was intrigued (I didn't know BB sold HK). My question is: does anyone know if the multi-channel inputs can perform bass management? I know the avr-635 could and the 435 could not, but I don't know about the 445s or this new 347. Seems like HK would have brought these features to the lower models by now. I'm also interested to know if it will upconvert everything over HDMI. Thanks

The 347 does not include bass management on the multi-channel analog inputs(5.1/7.1), the 445 does....
Regarding the 347 and upconverting via HDMI, yes it will take a 480i analog such as composite, s-video or component and output via HDMI @ 480p & 720p. It will also handle 1080i/1080p as well in the by-pass mode, 1080p In to 1080p Out..

I too work at best buy HT, i have a question, i own a Denon 2307. Which one is better the Denon 2307 or the Harmon Kardon AVr 347?..(sound wise which one is better for both music and movies, i'm using Klipsch RF 82's)

I have Klipsch RF5, RC7, RS35 and RW12. Until Friday, I owned a Denon AVR-2803. I would consider that a predecessor to the 2807. While the receiver was good, I would not call it great. I sold it on craigslist and bought a H/K 247 from Best Buy. For music, the H/K is much better than the Denon, especially connected to my Klipsch. With the Denon, I was getting some high frequency fatigued listening to music. With the H/K, the sound is warm and inviting. The sub seems tighter and musical.

The only problem I am having with the 247 is with video. I am seeing some video quality degradation with 480p source (SD-DVD from my PS3). If I connect the PS3 directly to my JVC HD-ILA TV, SD-DVD is output at 480p to the TV and the TV's scaler (which is pretty good) converts it to 1080p. This looks pretty good. I tested it with Lord of the Rings, and iRobot. However, connecting the HDMI through the H/K 247, the 247 upconverts the 480p to 720p (by default). Then the TV converts the 720p to 1080p. This introduced a lot of jaggies and made the image horrible. I then set the video option in H/K 247 to 480p instead of 720p. This retained the output resolution as 480p (1080i/p only does pass through). This almost eliminated all jaggies. However, the image is not a pure passthrough. It still has brightness/contrast/color settings that I might have to tweak. This is frustrating since I have already calibrated my TV using DVE and I don't want the AVR to introduce image adjustments. I wish H/K had a pure video passthrough setting.

Also, I am only running mine in 5.1 mode. So, I cannot gauge the 7.1 performance. I love the receiver (for the price), but the video problems might force me to return this receiver back to Best Buy. I have my eye on a Pioneer Elite 82TXS. However that is about double the price of the 247 and I don't know what other problems I will have with that.

"My question is: does anyone know if the multi-channel inputs can perform bass management? I know the avr-635 could and the 435 could not"

I don't believe the 635 has BM on 6-ch analoh inputs.

Hi Noah! The 635 definitely does not have BM on the 6/8 channel analog inputs. The 645 does and the 327 does not. Just finished running a 327 thru its "paces" for the past two days and it is going back tomorrow. Like the 645, the 327 does not pass multi-channel over HDMI when using HD DVD (Toshiba XA1) . The 327 does pass multi-channel over HDMI when using Blu-ray (Sony BDP-S1), but... The unit has the "crackling" over HDMI audio and just as bad, you cannot layer Logic 7 over the multi-channel HDMI . The 347 always reverted to a non Logic 7 default (5.1 multi-channel Dolby, I believe). The unit definitely would not retain the Logic 7 setting when the audio started and you could not switch to Logic 7 at that point.

Very disappointing because I love the HK sound and my 635 has been flawless for the past year and a half. If my 635 was a HDMI receiver (working of course), I would not have started this "quest". But after listening to the 645's working multi-channel over HDMI with Blu-ray (uncompressed PCM), it is difficult to go back to either 6/8 analog or coax/optical.

The EQSetEQ in the 645 did a great job for coax/optical (sounded slightly better than my 635), but then when you switched to multi-channel HDMI audio, the soundstage was wider and more defined, there was more dynamic sound, the surrounds (sides and rears) were more enveloping, etc. I can only imagine what some of the HD DVD disks with TrueHD will sound like when using multi-channel HDMI audio .

The Pioneer VSX-84TXSi is next up. I found new unit (February 2007 build) that has the new firmware to address the LFE issue. There have been several posts that state there are no issues with multi-channel HDMI for either format (HD DVD and Blu-ray) and the 84 is supposed to "passthru" 1080p24, so it is the next receiver in the "batter's box" : .

Hi Walter,

Cool, I'm real interested to hear how the 84 does.

I wonder when HK has plans for follow-ons to the 645/745, though maybe it's moot since they still can't seem to get HDMI to work right.
