    Rotel 1066 popping

    I bought a 1066 a couple of weeks ago and noticed today that I have a popping coming from all of my speakers about every 3 seconds. I turned to volume all the way off and the popping is still there. I put my hand on the edge of the woofer on my SVS and you can feel the speaker move when popping! I purchased my Rotel from a dealer in California when I was out there on business so I don't have a dealer in the area that would take it back. Is this a firmware issue or something that the 1066 exibits?

    Which firmware are you using? (Press and hold Mute till it displays the firmware)

    What gear do you have plugged into the 1066? If you have several items maybe unplug them all and see what happens...then plug in one thing at a time and see if that changes anything...maybe its some interaction between the 1066 and some device you're plugging in....which amps are you running? Try swapping amps or cables...can you borrow another pre amp or receiver with pre outs to see if that changes anything? (you could always "buy" a cheap receiver from best buy and see what happens when its used as a pre amp then "return" it before the 30 days are up)

      Thanks for the advice Andrew, unfortunately I have tried all of those things. I talked to the dealer that I purchased it from and he thinks on of the processing boards is bad. It has Version 2.1 firmware and has the updated 200mhz video switching. He was going to contact Rotel and get a RA number for me. I will keep you updated on to the process of getting this figured out. :?

          After searching the archives I noticed a few individuals complained of a popping sound when performing certain functions within the 1066, i.e. OSD navigation’s, but there wasn’t any resolution indicated. Well now I have the same problem. It started today when I decided to setup a 7.1 configuration by connecting an old Adcom GFA-545 to drive the two center-back channels.

          It happens each time I pause the DVD player, re-start it, and then wait for the 1066 to lock-in on the DTS-ES or DD-EX flag (I’m not an audiophile like many of you, but I think this is what happens). It's also apparent when navigating the OSD; for example in speaker set-up. When I turn-off the Adcom no popping is heard what so ever. I checked to see if the 12V-trigger switch was turned to the off position and it was.

          It's not a huge issue, but perhaps someone has a recommendation, fix, or work-around in lieu of powering down the Adcom and not using the back channels :cry: . I've been running V2.24 for approx. one month with no problems until today.

          Thanks for listening!

            I received my unit about 2 weeks ago, and I have that annoying 'pop' too. It is sooo annoying! I have the latest 2.22 (or whatever) rev. I have contacted Rotel support and they are in the process of getting back to me, but the biggest issue is that it is coming from the sub the most, so I get a really loud low level pop. It sucks! hopefully it can be fixed!

            RSP1066
            RMB1075

              JP: Sounds like this popping noise isn't an isolated issue! I'd be very interested to hear what Rotels response will be........can you update us when that happens?

              Last night my wife & I watched "My Big Fat Greek Wedding" for the first time (very funny BTW; reminded me a lot of my big fat Italian family), and since it contained a DD-EX track, I turned-on the amp for 7.1........POP! POP! Again, not the end of the world, but it's very annoying.

              TIA JP!

                  Is it possible the rsx 1055 could have that same popping?

                    Well actually my Sub is also poppin.

                    Dunno if it also pops when my 1066 is turned off. JP does your sub only pop when the 1066 is turned on or does it also pop when it is turned off??

                    Keep us informed please.

                      Looks like some of you have the same problem as I do. Check this out.



                      Mine also makes a low pop when navigating the menus

                          Whenever I have a problewm I contact Tim Wyatt. He's always returned my emails very quickly. I think his title is Technical Support Superviser.

                            Well i noticed that my sub also pops even when the 1066 is turned. So i wonder if the prob lies with the 1066 or the internal amp of the sub??

                              Wow, this is interesting. A similar noise from the Outlaw 950 is what made me get rid of it. I think this is a not uncommon problem with digital processors, worse with some than others. Even the Bryston SP-1 made a small tic when I switched digital formats. My Citation 7.0 on the other hand, is perfectly quiet at all times. It it is an analog processor and contains no DACs, but I think its silence is more a matter of superior overall quality. HT processing is currently done with a H/K AVR520, which is also perfectly quiet - now; but it made the same noises until I replaced my Chiro amp with the Innersound.s In fact, since adding the two Innersound amps to my system everything is now suddenly become utterly silent. So it is possible that switching amps may help. On the other hand, it may just be a design or implementation problem as you guys mentioned. But my noise problem with the H/K went away when I changed amps, so you may want to try it also. I recommend checking your connections closely also - a bad cable can sometimes cause this also.

                                I hear the same popping sound too, (1075 and 1066).
                                when I select something, I hear A low popping noise on my speakers.
                                So it is A common problem of the 1066!!

                                  yes, that's common problem. I've a little popping,too, when changing sources, surround programms, menu setup. I'm using RSP 1066 with Primare A 30.5 amp and Paradigm Studio Speakers.
                                  But when my system is hot, after 2 hours listening, popping is very very quiet. Ilike my system very much and I don't care about it
                                  I enjoy great cristal-clear sonud !

                                    I emailed him again on Friday, he said he was out of the office and would get back to today (monday) he's a great guy, I just want a resolution to the problem

                                    Last night i was listening to cd's, and whenever I stop a CD it pops! no offense, but that is insane!!! that should NOT happen.

                                      Hey Guys,
                                      At first I thought my poping during menu navigation was fixed by some new cables. After playing around a bit tonight I noticed that all my poping is coming from the subs. Each time I change a setting on a menu the popping is not coming from my front speakers like I thought it was. It's ONLY coming from my subs. My 1066 also pops LOUD when I turn the 1066 ON/OFF, so my sub out has a problem.

                                      Can some of you check and listen to whether your popping is coming from your mains or the sub?

                                      Thanks

                                        Legairre, I double checked the popping sound and determined that it's isolated to the center back channels and sub only when the Adcom (driving the CB's ) is powered-up and 7.1 selected in the OSD setup. Tim Wyatt responded today via email and indicated that he was checking into it and that he should have something in a day or so.

                                            jcbruck,
                                            Thanks for giving it a check. Maybe we have something in common with the sub out.

                                            Anyone else having pops from their sub out or center back speakers?

                                              Yeah we get popping too ... mostly out the rear centre but on other channels too - mainly the fronts (we havn't got a sub).

                                              We're not sure ... but think it started when we upgraded to v2.24.

                                              (Oh ... we're in the UK ... so it's a global problem)

                                                    I get the popping from my sub, as posted previously. Tim is indeed working hard to get a resolution.

                                                      I'm getting a bit concerned here, what with my 1066 on order for delivery next week. Does this thread imply that a majority of 1066 owners above a certain firmware are getting a consistent popping noise in random channels while music and movies are playing?

                                                      Has Tim implied that this IS a major problem with multiple units? Perhaps I should cancel my order...

                                                      Brian.

                                                        The popping noise come from all speakers, when you good listen.
                                                        Every time when the digital signal cuts off you hear a low popping noise, as layer change by DVD or switching DSP and track change by CD....Ill hope for A solution, because for that kina money Ill paid fore.

                                                          My 1066 pops too, but only on DVD layer changes and when I change channels using my DirecTV receiver. It's like it loses the signal from one station, pops and then locks onto the new one. Yeah, it's somewhat annoying, but by no means am I returning this bad boy!!! A firmware fix would be nice though... BTW, I'm running the 2.25 beta firmware.

                                                            OK, I wanted to post a follow up on this whole situation!

                                                            I have been speaking with Tim from Rotel on almost a weekly basis. I actually live within an hour of their offices in MA. So I invited Tim over the house to take a listen and get his opinion. To start, let me explain how I have always set up my HT systems, and how Tim recommended I proceed. First my equipment:

                                                            RSP 1066 (of course)
                                                            RMB 1075 Rotel 5 ch amp
                                                            JBL HT4V speakers (x2) front and rear
                                                            JBL HT4H center speaker
                                                            JBL HTPS400 THX cert Sub

                                                            Now, This JBL sub has a 'normal' and a 'THX' switch. (No spkr level inputs.) Normal mode allows the sub to set gain and crossover. The THX mode disengages the internal gain & crossover, and all options are controlled from the processor. I prefer to use the THX mode (even though the 1066 is not THX cert) because it allows me to 'see' the exact crossover point that is being fed to the sub. (I personally like the 80Hz setting) Now, if I set the sub to this THX mode, the 'popping' sound comes through constantly when switching sources and changing processing schemes. (Dolby/DTS) In this scenario, the sub is on THX, the crossover on the 1066 is set to 80, and test tone output I believe was around the 0 range. Under these circumstances, NOTHING I do eliminates or is able to diminish the audible pop from the sub.
                                                            If the unit is set to Normal- the pop is able to be controlled. By adjusting the gain on the JBL sub I am able to lower or increase the pop. So, the result was to turn the crossover of the 1066 OFF, and adjust all controls on the sub. This is what Tim suggested, and he stated the sub would be able to provide a greater level of adjustment than the 1066. Now, this is not a cheap sub ($2000), but again, I prefer the crossover on the processor, only for the fact I can visually 'see' where it is, as opposed to going by a dial that doesn't have any numbers on it. (other than a 50 and 120 mark on either end)

                                                            The speakers do indeed pop as well, and I have come to no conclusion why this is happening, and have been unable to reduce or eliminate it. Sorry

                                                            My speaker setup was vastly different than what Tim suggested. I have always calibrated my systems to 75db output using a Radioshack SPL meter (analog, not digital version). I have always left the processor at 0db in the test tone feature, THEN adjusted down or up accordingly to match all speakers to the same reference point. Tim instructed me to turn the levels DOWN to
                                                            -3db/-4db on the test tone menu. And from THAT point he recommended that they be adjusted up or down accordingly. He explains this is how Rotel calibrates in their demo rooms. He began to explain this has to do with the old design of Pro-Logic decoders. He kinda lost me as he is a real technical guy but at the time it made sense!

                                                            This is fine, I now have to adjust the physical 'number' volume of the 1066 higher in order to achieve that same output as previously, but I am still calibrated to 75db. This brought up a few key points: Does Rotel have to redesign the options within the 1066 so that 0db is actually -3db. (so you start lower) or does the manual have to explain Rotel's philosophy on this? I can understand what Tim was saying, but for a guy like me if the 1066 gives me the option of 0db in the test tone menu, then I should be able to use it and start from there. This is something that will have to be looked at.

                                                            I will be borrowing a friend's sub in order to perform some more testing, so I will post as soon as I have the results. Rotel is indeed working hard to get this issue resolved, they have been having some difficulty duplicating the problem in their labs, so this just may be a quirk that is occurring. Who knows?

                                                            Sorry this is so long, but I hope it helps!

                                                              JP, your A lucky man to have Rotel as neighbour

                                                              So what the technical guy is saying that it is A set-up problem?? I doubt..I discover A new ticking sound, when the sound is off and the volume is ON and you turn the Bass or Treble knob of the 1066 you hear a small tick in your tweeters of the main speakers, not loud but you hear it.

                                                              I think there's a internal problem in the 1066 that makes a distortion...

                                                              But i'm gladd that Rotel work on this problem (I hope)

                                                                From what I gather I do not believe they think it is a set-up issue. Tim helped me set up my system according to their criteria. Now done this way we were able to minimise the pop from the sub. They are indeed testing equipment to get to the bottom of the problem, and from what I have been told having they are having some units come directly to Mass offices for direct testing, from customers who have experianced this issue. So we should see some good results come about!

                                                                        Ron, I do indeed get popping when switching channels with a digital DSS system. The only temp resolution is to use analog connection, andd have the system default to analog. No resolution to this issue as of yet that I have heard of. According to Tim they are moving engineers around to help get a final resolution.

                                                                              I recently upgraded the software again ( I forget the number) 2.2 something

                                                                              The pop went away!!! but only for 10-15 minutes

                                                                              yes, the software upgrade did indeed take care of the problem, but only for a short period of time. (verified twice) So, I am indeed positive this is a simple software bug that will be taken care of. I have not heard anything else as of late from Tim at Rotel ( I am sure they are very busy!) but I have high hopes this will be taken care of shortly!

                                                                                  You know, I read ALOT of people on this forum that have problems with popping and signal delays, etc.

                                                                                  Yet, no one returns the unit. They deal with imperfections.

                                                                                  I realize $1600 isn't a TON of money for a high-end preamp. But hey -- that's still alot of money.

                                                                                  I had a problem with mine popping (slightly) and had a horrible signal delay. I returned it immediately, got a brand new one (with a better remote, too) and now i'm happy.

                                                                                  If there is a problem with your unit. Don't fuss with upgrades that you have to do yourself. RETURN IT.

                                                                                  Comment

It might be an interesting test to turn off the rotel like you do for a firmware upgrade and wait a moment then turn it back on and see if you still have the pop. I'm wondering its turning it off somehow reset something or it has to do with a static build up that the power off cycle helps to drain...until it builds up again in 10 mintues or so after been powered back on...
