Nice! Thanks. I'll look more closely if this doesn't work out.

My ATI 2507 and Hsu sub amps are protected like that with Richard Grey units. They provide energy storage as well for peaks though the ATI has a very capable power supply ... and I have my own transformer with a 400-amp service.

Sounds like and expensive solution. I'm hearing enough from manufacturers that it's not needed, that I will start without conditioning and see.

Power conditioning is optional due to that being built into the better quality units, but surge suppression is not optional. If you get thunderstorms in your area, you really don't want to "see" how it goes.

Yeah, I agree with surge suppression Jeff. But no thunderstorms in Alaska smile.gif

You got those lights though, no induced electrical charges from them?

Can someone confirm if the outputs on the Onkyo PR-SC5508 are indeed fully differential and balanced?


Which particular DAC chips (and how many) are used on the SC5508 and are the outputs of the DACs fully differential?

Does the DAC output pass through a non-differential stage on their way to the XLR output - as in - is the entire signal path from the DACs and through-out the analog stages and to the final XLR output fully differential and balanced?

It's not fully balanced all the way through.

True, but it is still balanced and yields the advantage of being able to use longer runs and be EMI- and RF-resistant.

I just picked up a like new 5508 unit and I think Audyssey is trying to do weird stuff. I have a sherbourn 7-350 amp and used it on my other onkyo tx-nr 1007 and did not hit the-12 dB limit on any of the seven channels. When I ran audyssey on my new 5508 using xlr cables it is putting every channel at -12 dB. Even my rear speakers that used to be -1dB on the 1007 unit.

Also the sub is SUPER weak. It made me turn down my Crown XLS-5000 pro amp to about 4 clicks or about 1/6 volume to hit 75 dB before kicking off the calibration. After the calibration the bass was so weak as to need to turn it up a full 10 dB to even be tolerable. (Still less than I'm used to with the 1007 at post audyssey config).

I tried both the new audyssey Mic and my old 1007 audyssey Mic. Very similar result. This is disappointing. I guess I'll try going back to RCA cables instead of xlr and see if that straightens out my issues? I can manually set levels with my omnimic, but what ifs going on?
post #2681 of 2742
I ran Audyssey again with RCA cables this time instead of XLR cables. Still all my channels are -12 except the rear two surrounds in my 7.1 setup. They are now -6 and -9dB instead of -12dB. These used to be -1 to +1 range every single time I ran Audyssey on the older TX-NR1007. Something is still off. Is it possible the 5508 just has higher voltage RCA outputs than the 1007? When I did a test tone with the RCA the Left Front was at 76.5dB after Audyssey. When I did the same test tone with the XLR left front it was at 83ish range. So that's a difference of about 6+ dB's between XLR and RCA - so that's part of my issue is that XLR is a much strong signal on my gear -- BUT why such a difference between this 5508 and my previous 1007 using RCAs? My Onkyo 1007 would pin the front speakers at -9dB instead of -12dB (and -12dB still isn't 75dB on this new 5508).
post #2682 of 2742
So I have a suspicion about the above experience coupled with my experiences tonight. I turned off Audyssey and any automatic EQ function to off and used my omnimic to calibrate SPL levels manually to 85dB trims. I found that test tones on the 5508 just seem (for some reason) 10dB louder than on my 1007. For instance - with my Onkyo 1007 using the Sherbourn 7-350 amp Audyssey calibrated Left and Right speaker level trims to about -9dB or -10dB every time, but on my 5508 as noted above it put the trims at -12dB and when I measured them they were actually about 83dB.

So if I manually accomodate and slide reference level to now -10dB on my new 5508 I can increase the trims on Left and Right and be at -10dB for left and right just like my 1007 - but my internal test tones are at 85dB on Onkyo 5508 vs. 75dB on the Onkyo 1007. Is it possible the that Onkyo TX-NR1007 calibrated for AVR test tones at 75dB and the 5508 calibrates for its test tones at the true 85dB level?
post #2683 of 2742
"inline attenuator"

Probably -10dB, one for each channel. Maybe none for the sub channel?

I lost my onscreen menus. Are there settings that can bring it back?
I never had onscreen OSD (volume etc).

I bought a refurbished 5508 a year ago and could not get the on-screen menus for the first couple of weeks, then after playing with settings I finally got them to appear. Now I have lost them again.
I only have HDMI inputs. I have tried changing the pass through, resolutions, etc.

Any hints.

Thanks much.

Can someone confirm after they run Audyssey what SPL the AVRs test tones on the 5508 are played at?

75dB or 85dB?
post #2687 of 2742
GRBoomer, I have the same problem. I didn't even notice I didn't have my onscreen menus, and ultimately didn't care that much (I had them turned off on my last Onkyo TX-NR1007), but I can't figure out how to get them to turn on. I turned them on in the setup menus, but they don't show anything on the screen on neither the main HDMI out, nor the second HDMI out. Luckily I just bought my unit from a guy here on the forums and it's still under warranty - so if that's the issue I can get it fixed without any hassle. I'm going to open a customer service ticket with Onkyo and find out if I'm missing something to get the onscreen menus to appear?
post #2688 of 2742
Anyone experiencing this problem? Currently running Onkyo PR SC5508 in 9.2 configuration.

I noticed my left back surround was dead. I went into setup for the speaker calibration level. I get no test tone from that channel. Checked and tested speaker (even swapped it with right back surround). RCA cable is fine also. What was even stranger is the left surround went out next but it sometimes comes back. To add to the mystery, when I went to check the levels of each of the other channels they all worked but with one twist. When the test signal is sent to the right front it is heard in both the left and right front at equal volume. The left front when selected works as it should. Is it time to send it for a repair or replace it? This is my 2nd unit. First one lasted about 50 days before a problem. This one has been solid for just over 2 yrs.

If you can use the component output to see if anything shows up. Then check to see if the HDMI output is set to Auto. If it is set to something else and it doesn't match the TV set monitor resolution it will not be able to be seen.

75dB on mine.

I got 75dB also.
post #2692 of 2742
The test tones are 75dB. "Reference" is 85dB. They were concerned about having 85dB tones coming out of peoples' gear, so they dropped the level of the tones back and compensated for it in the internal calculations.

75dB.

When the HDMI board goes kaput, do the other non-HDMI sources stop working too, like tuner? I have to power this on/off multiple times to get the sound. Started doing this about a week ago.

I know that the networking function is also on the HDMI board.

post #2696 of 2742
Thanks Jeff. Looks like I need to ship this in. What's the typical time frame for Onkyo to get this repaired and ship it back. I was on hold for good 40 minutes and then hung up :-(
post #2697 of 2742
onkyo's customer support through e-mail is no better - it's like 2 week long delay's between replies with the CSR saying they are extremely busy right now and they apologize for the delays.
post #2698 of 2742
BTW - my HDMI overlay (on screen volume) doesn't work on my 5508, but the networking function does still work. The setup menus all function normally on mine however.
post #2699 of 2742
I'm lucky enough to be in the Chicago suburbs, and a regional repair center is about 25 miles away. Since the HDMI failure is well documented, I didn't bother with Onkyo, and just dropped it off. The repair was turned around in a week (this was back in February 2013). Perhaps you could call the regional closest to you and work with them directly. When my HDMI board went out, the entire unit was useless. YMMV.
post #2700 of 2742
hawkster27 - can you just take it into an Onkyo authorized service center without an RMA or warranty approval from Onkyo?
