I don’t think the SC5000 has a mechanical hard drive inside.
It’s a bit of a weird sentence. I had to read it several times also.
The SC indeed has no disk, so I fail to see the comparison to the noise a computer HDD generates on a mixer.
… just the electronical noise between the controller of the usb/card reader, chipset and so on,… its a standard phenomenon and can be reproduced on older pc machines, and modern too, yes, really… firmware issue are as you said above: muting diabled before the track are finished loading. thats all. no error, no bug, no s*** player or so on…
and: i never had the fader on while a track are loading while mine sets.
of course you just listen to tracks, perhaps the fader are always on, but like i say, need just to refixed.

Thanks all for the input.
Few things:
-
There are no ground loops or other electrical interferences. These noises are generated by firmware 1.2.2. There are zero noises or other bugs in 1.2.0. Means there is nothing wrong with the hardware or the wiring.
-
Do NOT lift the ground on these units. I know it is a popular and easy way to fix ground loops. But notice you are touching steel units with built in PSU’s. If you cut the ground on these things, you are putting yourself in a lot of danger. This is not worth the risk. Just don’t. There are numerous ways to fix or reduce ground loop noise. Turning your player into a potential death trap is the worst thing you can do. It also has nothing to do with the issues I described.

Can’t speak to whether or not firmware is at issue here as I’m using an 8k and not 5000’s but wanted to also encourage people to not break off the ground pin on their cables. Doing this defeats the most important safety feature of your unit. The pin is there for a reason, to keep you from dying from electric shock should the metal chassis of your unit become energized due to malfunction.

Now that’s possible. I presume you guys mean the analog outputs from the SC5000. A lot of digital audio gear mutes the sound when in certain states to create the illusion of lower noise floor. The latest firmware might just not do that anymore. That and the supposed compression going on could be to boost the measured S/N ratio and/or deal with RF/EM interference issues people have previously mentioned, like when your cell phone is near the screen, etc, that InMusic supposedly resolved somehow. The compression and auto muting might have been the somehow. Or you could just have some defective units. Anyone else noticed this on either the earliest firmware or the latest?
To stay a little bit on topic.
Yes there is a digital ticking sound when both faders of both layers are up, while one is playing and other loading a track. (My players are all connected digitally btw.)
Seldom use the second layer so took some time to check and can confirm.

That’s bleeping weird, though. I think the other guy with the SC5000s and the MP2015 said it happened to him at one time with a cell phone close to the screen and like connected to a Urei or Bozak, but he also said it was happening over the SPDIFs, too. He also had some not entirely shielded speakers close to the players. This is different than poorly-designed analog outputs or something. Like a clock problem or I’m kind of at a loss.
No it’s not external interference. It seems to come from the loading of the track into memory or opening the Engine generated waveform from the database to display on screen.
edit: text went double in reply (started on pc, finished on iPhone)
Could be internal interference, but the question then is on what…
Must say i am getting a little dissapointed with these players. I mean, i spend a good fortune on them expecting at least stability and excellent sound quality out of the box. The extra features, like dual layers, sealed the deal for me.
But now it seems my two very basic demands for any player (and one of the reasons i moved away from Traktor) are not met. These players are not stable and the sound quality (see http://www.denondjforum.com/t/sc5000-high-end-roll-off/5602/161) isn’t top notch either.
Now i don’t know if both my units are defect, but that would be a really silly coincidence. But i am considering to put them up for technical service by Denon. Shame.

Be your own person.
Don’t be led by others attempts to rock the boat. The features that you liked a few months ago are still there.
Even luxury cars aren’t immune to faults.

As a new owner of SC5000’s I wish there was a bug list somewhere, so I would know if this had been acknowledged already. Sorry if this is a documented bug.
I encountered this issue today and it was easily reproducable.
- Connection via digi-out to an A&H DB:2
- 240gb ssd drive in the rear usb-port, also tested with the front connection, same results
- Digital stuttering noise is clear on the layer that’s playing when loading a track to another layer
- Only the channel with the track playing was on
- This seems to happen only when loading tracks with hot cues
If you use the rotary encoder instead of the touch screen and you keep your hand away from the platter, does it still happen? You can also try just loading a track with your right hand while the left hand is touching the rear-left grounding screw on the back and see if that makes any difference.
You’re on the latest firmware?
How many hot cues saved does it take for it to occur?
Is it only with certain file types or very long/big tracks?
Does it happen early in a set, late in the set only, or pretty much throughout?
Only on the linked deck or even the deck the drive is directly connected to?
Does it happen through the analog outs, too?
I had the very same issue with my 1TB SSD, except for the hot cues. Never had anything like that with SD cards. My solution: I changed the SATA-USB adapter to a more expensive one. Haven’t experienced the problem since. Only sometimes the linked player seems sluggish.

I’m using a USB-C drive with a 3.1 gen 2 port so the drive speed shouldn’t be an issue. The adapter is high quality as well. I’ll do more thorough testing tonite and will also try with the older firmware

I will try this tonite, I used both the rotary and the touch screen when I noticed the noise.

Yes. Will downgrade to 1.2 to check if the problem dissappears as it did with a former poster on this theread

One is enough, althought the ones I tested with were in either the very beginning or 16 bars into the track
Is it only with certain file types or very long/big tracks?
Will test, but this happened with AIFFS, I will check with other formats tonite.

I noticed it at first an hour into playing. Powered off the machine, waited a while, booted up and the problem was right there with the first 2 tracks.

I only have one, so this happens when two layers are in use. The noise appears on the track playing on say, layer A, when you load a track to layer B.
Does it happen through the analog outs, too?
Will test this and will also test with another set of coaxial cables.
I don’t think the problem is about speed. A USB 2 drive would be fast enough. My guess goes toward the I/O protocols that might give the SC5000 a hick up. If it was electrical interference, then it should occur consistently, also with no track running.

Yes, that makes sense. I’ll investigate this further with different setups, but my guess is that it has something to do with the drive compatibility and/or digital audio i/o. I need to narrow down if there is a direct correlation with specific tracks/file formats and if indeed the hot cues play a part.
(I did notice the speed-up issue which was reported before which also incl hot cues - ie. sync on, the non-playing layer has a track with hot cue, you either start it from the hot cue point OR scroll past it with the platter - this momentarily affects the speed of the layer that is playing a track. I tend not to use sync, so not a biggie).
