Kind regards,

That isn't a light, it is blue trim. Rotel's photography makes it look as though it lights up, but it does not (thankfully)

does this unit run hot.
I am looking for a good preamp and hopefully one that doesnt run hot--I had the 1066 and now using a yamaha to tie me over.Both of these units run very hot.I have the large 1095 5ch amp under it and a large prof NAD under that for the subs--so trying to keep the heat down abit.I have a small fan blowing cool air on them.Any suggestions for a great preamp that has 1.4a hdmi too.
just started looking
thanks

Wow. What a difference over the Onkyo. I didn't realize what I was missing. The detail coming from the tweeters is remarkable. Just need to dial in the bass a bit to hold me over until I get some EQ software.

I ran through a several CDs from my Oppo including a couple SACDs. There was a 2 second lag at the beginning of the first CD I tried, when I switched from a Blu-Ray in Dolby TrueHD to 2CH, but after that, not a single lag or audio mute, even at the beginning of CD's when changing them out.

Haven't seen it mentioned, but there was an addendum included with a sticker to put over the power light if it's too bright for your tastes. I'm trying it out in the pic below. Not sure if I'll keep it on or not.

They all have the audio clipping issue.

I've done some experimenting over the past couple days. The only clipping I have heard was when the output format changed at the start of the album, and even then, it is less than a second, not the 2 seconds I have seen posted by others.

I have found that when the format is selected beforehand, there is no clipping. I have not experienced any clipping between songs at all. For what its worth, the cabling has been Monoprice and Blue Jeans HDMI, and an Audioquest 3.5mm to RCA for the Airport Express.

Here is what I have tried:

CD - PCM 2CH from Oppo BDP-83 via HDMI
SACD - Multi Channel PCM from Oppo BDP-83 via HDMI
DVD-A - Multi Channel PCM from Oppo BDP-83 via HDMI
DVD-A - PCM 2CH from Oppo BDP-83 via HDMI

CD - PCM 2CH from PS3 via HDMI

MP3 - Streaming iTunes from Macbook Air to an Airport Express via analog

My unit has stayed pretty cool. There are a limited amount of vents on the top right-front, and on the left side. The vent area is warm after use, but the rear of the unit isn't. I have an open stand though so it gets plenty of ventilation.

Thankyou for your reply
sounds good and will look into this preamp.
I do miss the quality of my Rotel 1066 preamps audio quality and would like to replace my yamaha with a new rotel
thanks again

Thread Starter 
Just a followup to what is posted above. I have not ever had and skiping of CD or DVD so far. My 1572 runs warm but not hot. Just wanted to reiterate that not all units have the skip issue.

I'll try this. In my experience, selecting two-channel prior to playing a CD definitely makes the play seamless but It's nice to use all the speakers. I certainly get more volume that way. SACDs don't have any problem even without first selecting the mode.

Can we try to come up with a different term besides "clipping?" Clipping means something very specific when talking about audio and it gets kind of confusing.

What about "Handshake Mute"?

About using all the channels...you can adjust your source in the Rotel set-up menu to default to almost all of the playout formats, including 5 or 7 channel stereo. When the source is selected, it will automatically go to what you set it at. I have the Airport Express feeding analog into the CD input and outputing 5-Channel Stereo upon selection.

That would work except that handshake might imply that it is an HDMI issue, which I don't think it is. What about trimming? It sounds like you are suggesting that setting defaults for the audio processing of each input is the way to avoid the issue? I'm going to try that.
post #131 of 196
Everything I have read about the subject leads me to believe it is an HDMI handshake issue. I've seen in posted elsewhere that some experiencing the problem have ran an optical out from their CD player and avoided the muting.

I only have a handful of hours with the processor, so I am by no means an expert, but the behavior is very similar to what I experienced with an Onkyo 805. The processor takes a bit to confirm what processing needs to be done between the devices and mutes while doing so. At least with the Rotel, there isn't a mechanical "click" every time the processing changes. So my suggestion to change the default processing might help save a second in processing time, and was merely a suggestion to try.

Everyone has the same unit, and if everyone's firmware is up to date, then the only differences between users is the devices they have hooked up. When these devices are connected via HDMI, and handshake varies between them, problems arise. Thankfully my PS3 and Oppo don't seem to have much of a problem with the Rotel.
post #132 of 196
There is currently no way to disable the OSD, which pops up when changing volume or the processing format changes. I called customer service and was told they are working on a firmware update that would make an ON/OFF selection in the menu. Yay

It is not a handshake issue. Rather a design decision that was made years ago and continued to reduce expenses associated with implementing a brand new design.

The unit looks for an Analog signal first by default.
post #134 of 196
Okay...so it looks for analog first, doesn't see it, then moves to HDMI. The processor then confirms handshake with HDMI, muting the audio in the mean time. Since not all devices handle HDMI handshake the same, some are experiencing a longer mute than others. Sound about right?

Correct...and others like the new nad processor defaults to a digital input first.
post #136 of 196
I'm still not buying the "looking for an analog signal" when using the HDMI inputs. When you set-up the inputs, you can specify that the audio defaults to HDMI. Why would the processor go around your default settings to look for an analog signal, then go back to your default?

Rotel isn't the only company dealing with handshake mute. In fact, the Rotel handles it better than some I have heard.

You don't need to "buy" anything. If you are happy with the product, congrats on your purchase.
Turn it up and enjoy.

I did have minor sound delays via HDMI with the 1572 at the start of a disc or chapter/track while it locks on to the sound format (and with other HDMI processors and receivers I have used - except Denon). When I switched to decoding in the player (Cambridge 651BD), all delays disappeared. I know most like to see the DTS HD or Dolby True HD show up on their processor display, but really, there is absolutely zero difference in sound quality.
post #139 of 196
Anyone play with the Bluetooth dongle? I tried it out today, connecting with a Macbook Air and streamed Apple Lossless tracks from iTunes. I'm pretty new to streaming over bluetooth/USB though, and also with "lossless" file formats. Are there limitations with Bluetooth? Is the Lossless even getting received by the processor untouched?
post #140 of 196
if it's a2dp, it's lossy

So are you suggesting that we all forget about any digital processing in the 1572 and use the analogue outs for all our equipment? That's not really an acceptable solution.

Also, this is NOT a handshake issue. It happens with the USB input. It happens with an optical cable. When the 1572 makes sound it is quite fantastic. But if I lose the first second of every track of an album I am playing off my iPhone then what's the point? They need to fix this and they need to make it a priority. The big features of the unit are the 10-band digital graphic EQ, the extensive DSP, the front USB input. These are the features that distinguished the 1572 from it's predecessor. What's the point if you use only analogue inputs? what's the point if it creates this repeated annoyance with every digital source? All pleasure is dissipated by the repeated annoyance.

Completely agree - well put.

Thanks. I'm wondering if there will be any feedback from the company on their efforts to fix this issue or if we are just left here to bitch and moan, our two grand already taken.
post #144 of 196
Bitch and moan only. From my understanding, it's not a firmware fix.

Since you don't like the processor, is returning and exchanging for something else out of the question?

I just received the XTZ Room Analyzer. Can't wait to test it out.

Unfortunately, I received the RSP-1572 before any other components and before I was able to schedule my HT install, which involved opening up a lot of walls and doing electrical work. So by the time I figured out that this issue existed, the period of exchange had long expired. Otherwise, I would. It pains me to say that because I love the sound but the repeated annoyance, especially when watching a show off a DVR, actually impinges on the pleasure. I can't afford to simply replace it. Otherwise, I'd probably do that. I can recommend that no one buys this until/unless they fix this issue. That I will do.

If you or anyone else are not happy with this pre-amp, due to the audio dropout/clipping issues, and, want to sell or trade your units, please hit me up via pm!

Not everyone is experiencing the issue as you are though. I recommend auditioning the unit at your dealer and base your purchasing decisions based on your own experiences.
post #149 of 196
I had a couple hours to play with XTZ and the Parametric EQ. Pretty cool stuff. I only used the first 5 bands. Need to play around some more....

Before



After

Did that work?

Just an FYI, the Cary Cinema 12 has issues with certain DVRs where when you jump forward or skip back, it'll lockup and sometimes take up to 30 seconds to get going again. Although its audio quality, according to most owners is phenomenal, I really wouldn't want to get involved in all that. Some say that its not all DVRs but certain ones and obviously, they can't tell you which ones.

It also seems that some other prepros have this problem but ironically, its not the Onkyo's, Denons, Yamahas, Pioneers, etc.
