How do I disable the PLIIx? I have the audio set to Auto Select which should let the receiver select the best mode.

The auto-select is selecting PLIIx because your Dolby source contains fewer channels than your number of physical speakers. If you want to override the selection, you can manually choose your surround mode with the "Surround Modes" button on the remote. PLIIx is used to produce additional channels in content that may not include 7.1 channels. True 7.1 content is becoming much more common now, but is somewhat rare in movies even as of a few years ago.

PLIIx shouldn't be a problem, my receiver applies it to TrueHD streams without any issues. You should verify what your source is actually outputting to receiver.
post #1443 of 1529
The input from the source says TrueHD, etc so it's receiving the right signal. I guess the receiver is adding PLIIx because the input source is only 5.1. I did try Tron Legacy which is a 7.1 movie and it showed up fine.

I'll be with a technician the whole time they'll be testing my unit.
I've had it for a while now since the fix and it's worse than ever!
Sub 2 out NEVER works. I ALWAYS have to change to another input then back to activate it.
My unit now gets REALLY hot to the touch. I have problems keeping my finger on the back after an hour of normal use!
It also gets crazy hot with the unit in the on position and nothing is playing!
I'm having hum with PCM is activated,,,it's crazy!
Display still lags here and there.
The EZSet/EQ is worse than ever...the specialist told me to not use it!!!!
Will keep you posted

Well this is my final update...
The good:
They modified the bias voltage from 15mv to 12mv and I must say my subs sound absolutely fabulous!!!
Remember I have 4x 15" drivers...soon to be 4x 21" drivers.
As a matter of fact, I had to lower the power to the subs...it is that much stronger and sound better too!

The Bad:
They cannot fix the sub2 output not coming on when I turn the unit on.
It clearly did it there when I was at their working bench.
They were 3 and one kept talking to me throughout the process. (distracting from what they are doing)
He said it could be my amp and that it's not taking the signal...PLEASE!
The 2 sub out are connected to 1 amp. Even when I change the wires around, the 2nd sub out NEVER turns on...NEVER!
I switched the cables around...nothing!
I switched inputs...nothing!
I switched outputs...nothing!

I have to live with this MAJOR FLAW!!!!

To activate the 2nd sub out I need to change input and then back to the right input and sub 2 works.
This is with or without a signal...this is the ONLY way to make sub 2 work. PITY!

Aside from that...the 7550HD sounds and plays GREAT!

Once again...I GIVE UP!
I also give up with EZSet/EQ...I believe this is designed for people who have mediocre speakers and this is what the guy said too (Master Technician)
Regarding the heat, it is slightly improved because of the bias voltage adjustment they did.
I was told that it doesn't matter that it heats up...it is designed for that...he said

Regards,
post #1445 of 1529
Glad to hear things are somewhat better for you. I was hoping there would be a solution for the sub 2 output since I have the same issue.

So while watching TV today I noticed the fan kicked on. I went to check the receiver and I could feel the warm air coming out from the rear of the receiver. The small fan on the side was running but it was silent. The receiver is sitting in the open on top of a A/V rack with nothing around it. I was watching TV with the receiver volume set at 38, so not very loud. The fan wasn't whining, I could just hear it running. I take it this is normal.

Normal, though the noise is certainly distracting. I've gone through 3 7550HD's but the current one seems more tolerant to heat before the fan kicks on.

received my replacement refurbished avr 7550. its pristine and so far works great. seems like i made the right choice in not getting my old one repaired. the accessories look a little worn compared to the ones i returned but i can live with that. also the fan seems to run less frequently than my old one. question. when running the ezeq are people pointing the pointed end of the microphone up towards the ceiling or aiming it towards the speakers? i get different results depending which i choose. regardless i get a low subwoofer level that requires me to add 3-5 dbs. experiences?
post #1450 of 1529
I've had my 7550HD for a week or so now. I've noticed that while watching programs it flashes a green screen 2-3 times/hour. Our old AVR2600 never gave us problems like this. Maybe a flash once in awhile. Should I send it back for a replacement unit or would I be better off spending the money on a different receiver(Marantz 5006,6006, Onkyo 818,or other brand)? The 7550 was going to replace our 2600 but the green flashes are very annoying.
post #1451 of 1529
is when you are watching tv from the cable box? i have comcast and avr has hdmi handshake issues with the comcast box. similar to what you described but only on start up or switching to hd on demand programs. the problem is with the cable box not the avr from my research. no issues with my apple tv or dvd hdmi. i connected my cable to the avr using component and problem went away and picture looks as good as the hdmi. good luck.
post #1452 of 1529
Its through my direct tv box that's hooked up through hdmi. My 2600 didn't have this problem but once in a great while. Like I mentioned the 7550HD does it 2-3 times/hr.
post #1453 of 1529
you might try the hdmi bypass setting and see if that makes a difference. also could try connecting with component. this is assuming your other sources don't have the same problem. if so something is wrong with the unit.
post #1454 of 1529
Has there been any update on a successor to the 7550HD? Earlier in this topic it was stated "Fall 2012" for new receivers, but I'm starting to question if H/K will be producing another flagship model anytime soon.

My 3rd 7550HD has now developed an issue with constant static coming out the surround back channel, loud enough to hear from several feet away. Swapping speakers, wires, and sources didn't accomplish anything, it's definitely the channel itself. It's still audible when the receiver is muted or the headphone output is engaged to cut the signal to the speakers. Not sure if I want to keep playing roulette with exchanges, jump ship to another brand, or wait for a new H/K model to be released. The 7550HD is nice when it works but I'm at the point where mine is rarely fully functional.

They just added a new model on the HK website, it's a lower model but that’s an indication that the new receivers are rolling out:).

Wow, new receivers look like a fail to me. Sure they got shiny new features but just look at the specs for the AVR 1700: 12.8 lbs and only 260W of max power consumption even though it's rated at 95 watts a channel with 5 channels driven. rolleyes.gif

I am eager to see their new flagship unit but if these are an indication of where HK is heading, I will most likely look elsewhere when it's finally time to upgrade from the 7550.

The mentioned 1700 is significantly lighter in unit weight as it uses an SMPS (Switching Mode Power Supply) rather than the traditional linear power supply with an EL type power transfomer. This saves weight (about 7 LBs) and provides global multi-voltage capability for 120V-230V, just swap out the AC cord for the target local market. Also they are using more liberal published power output specs similar to the competition..

Interesting. The 7550 was rated at around 100 watts/channel with 7 channels driven but the max power consumption is listed at 1405 watts. Even at idle it's pulling 120 watts.

Does that indicate that HK has gone away with their high current amp designs? Any ideas on how their new flagship receiver will spec out?

The 7550HD (760 in Europe) was designed and built by the original HK AVR design team and these experienced guys have gone on in different directions. Many were hired by Onkyo, a couple to Marantz, some retired and others have moved on to new ventures such as Dr.Dre, and others into the newer, advancing product categories such as wireless audio/video systems/applications. rolleyes.gif

Going forward...
The AVR1700 and other models to follow are from the new team which are new hires and based in China....
How well the new products perform has to be proven. Stay tuned... cool.gif

My last (2nd) 7550, a refurb, had this same static/noise from the surround back from day 1 - but only one side (SBL)
Do you have this problem in one or both channels?

I've experienced occasional green flashes with all three 7550s I've had, using a variety of sources. I just live with it. I don't feel an exchange will benefit you unless the flashes start occurring more frequently.

Same here, running component from Comcast box to the AVR with SPDIF coax for audio - no more audio or picture drops to worry about. I get green flashes and dropouts from the comcast HD DVR boxes even when connected directly to the displays.
Only problem is that with my current 7550, all of the component inputs have a very DARK picture so the picture settings/brightness has to be maxed out then the color boosted to look close to 'normal' . Don't feel like dealing with exchanging it (again) yet

Well, you are not alone with this weird problem!
With my first two 7550s, I never had a problem with the sub2 output - that I noticed at least. Originally I had the remote programmed to switch the AVR to the Cable source (my most used) on power up, so it was not uncommon for me to switch source right after power on.

I was hardly ever using my current/third 7550 after setting it all up, and did not bother to program the remote as I had previously. It wasn't until a month or so ago that I turned the unit on to the "media server" source using the source select button and experienced this same problem, noticing the LED on my second sub wasn't coming on. Volume was low so was thinking sub's auto-on didn't kick yet - but higher volume did nothing. Manually turned on sub power, but no signal. Went to speaker setup and had to run the test tone for the sub output to work. Turned unit off, back on same way to same problem. Test tone required to get sub output going.
Several hours later turned unit on to media server once again to listen to music, same problem. This time switched to Cable and second sub immediately kicked on with source material.

Catch: If I turn unit on to "Game" source input (which I am using with an xbox360 over SPDIF optical, HDMI going right to display, not using AVR OSD+HDMI output) the second sub will turn on and work perfectly, every time with no fiddling. "Cable/Sat" (SPDIF optical/component video, using AVR OSD+HDMI out) is also working without issue.

Does it happen to you for all sources?

Yes it does...

Another major problem I have with the sub out performance.
I've noticed that sometimes when I turn my unit on...some days it seems I have more bass and then some days there's hardly any bass.
I just did some major testing and found out the following:

A major problem I am having is it will not hold it's settings.
Let me explain.
I have the SUB1 connected to my front 2x 15" subs
I have the SUB2 connected to my rear 2x 15" subs.

I tune the SUB1 to my fronts with the SUB1 "Distance Control" while palying a 80HZ test tone till I get the loudest sound.
(You put the fronts on large) Shut SUB2 when tuning the SUB1
I do the exact same thing for the SUB2 out. (Always keeping the front on large and shut SUB1 in this case)
(This is a great way to tune in your speakers with the subs)
Once calibrated the bass is phenomenal!!!! You will freakout how much more volume you get this way!!!

The problem is once I turn the unit off and then back on the settings remain the same but the bass is all out of tune and I must do it all over again.
It seems it will not hold it's settings.
Yesterday I noticed that just changing source screws everything back up!!!
It's royally f'ed up it's not even funny!

I have an RMA to send my unit in for a 3rd time. I have 0 faith they will fix anything!!!
I asked for another unit...was told they have none!
This is in Canada and with Jam Industries as the authorized repair depot for Canada.

I'm completely discouraged with my 7550HD.

That's scary.

I hope it doesn't rule out surround processing technology trickle-down from Lexicon.

Though that may be moot if they ruin the sound.

I have this problem in one channel only, and it's the SBR. I may be imagining things, but I swear it's getting worse. It certainly wasn't there when I got it.

I also have a sub 2 output issue, but the receiver is always on Media Server when I turn it on. I'll see if the problem occurs with other inputs too.

Keep in mind...
That 70% of Harman revenue (& profits) come from their OE car stuff..
This is where their R&D $ are going, and yes they have some incredible DSP algorithms in development. After being implemented into the OE car category they will filter down into the Mark Levinson, Lexicon and their high end life-style brands, then finally into HK AVRs..
This will take a few years. cool.gif

From the MC12 thread in the High End forum, it's looking like years to even show up in a Lexicon.

Is there a software to back up the settings of the AVR 7550?
It would nice to have a backup just in case.

Judging by what I read this would be a welcome feature for many users here wink.gif
post #1467 of 1529
The new Harman Kardon app in the iTunes Store mentions upcoming 2700 and 3700 models. No mention of anything higher end.

I realize this is all circumstantial evidence but I'm starting to doubt there's a successor to the 7550 planned anytime soon.

Hopefully they will leave the amp sections alone, though I'm sure (and we have already seen) the power supplies will become increasingly anemic with successive generations.

Might not be all bad. Modern HKs are somewhat notorious for being buggy - maybe they can improve on this reputation.

Nope. There are settings worksheets in the manual you can write in, or print out the PDF versions from the HK support site. Better than doing it off the top of your head...

Mine never got worse, then again I wouldn't doubt if my total use on #2 was <20hrs before it died. Noise would be there even with entire main zone off, only Zone 2 on (using Abus output)
Very annoying, but didn't feel like exchanging over it.

Let us know what you find with the sub 2 output / source correlation, though I haven't messed around with it much it seems limited to the media server source with my receiver.

Wow, you really have terrible luck with that unit (and Jam)
Only changes I've noticed between uses is overall volume. With EQ already on per given source - sometimes it will be significantly louder than usual even with the same source content (not sure if you've experienced this, but have many noticed a big volume jump when turning EQ on and off. Mine seems to sometimes be normal, sometimes bump the volume up, when turning receiver on OR turning EQ on and off manually.)
I don't want to make you wipe out all your settings for nothing, but have you done a processor reset?

That means lots of work esepcially with custom input names etc. - it seems like this is something that most if not all manufacturers get wrong. Not funny to have made custom inputs and EQ settings for hours and then having to redo them because the unit was sent into service - not very customer friendly to say the least!

There's no question now, the noise in the SBR channel really is getting worse. I contacted HK again, and was offered yet another exchange for a 7550HD-Z or a new 3650. I opted for the 7550HD-Z again.

At this point, I'm tempted to leave the box sealed when I receive it and sell it for whatever I can get for it. I don't think I can put up with exchanging these so often anymore.
