Digital Sample Rate Settings On X1850 Mixer

Hi - Yes the cables that you get with equipment is not the best but the one’s from Denon are not to bad to be fair, but yes better ones for the best quality is correct.

Yes a small amount of background noise can be heard, not much but it’s there.

My use is multiple in some cases I I would have all 4 inputs digital from the SC600s and digital out (all my own digital copies that I make are 96k / 24 bit for these players). But other times I use 2 digital one from each player and 2 analogue from SL1200 so digital and analogue side by side.

Also some times my need is to use the analogue output depending what I am doing.

When I first posted this I thought it was just a fault with my one, since then I know this is not the case. InMusic, when I last had contact could not find what was causing this problem this was some time ago now. Plus a friend of mine said as things are a little different to what I believed at the time I should re-post it to make others aware, what they do is up to each individual. Also I was told at the time I was the only one to report this hopefully this lets others to know what to check for. Plus it’s been some time without it being rectified.

This post is purely to make to make others check there mixer and report it if necessary.

Also I am a firm believer that if it says in the spec it can do xyz then it should it’s what you pay for.

Each channel’s analog line inputs on your X1850 are noisy only when the mixer is set to 96khz, or is this just an LED glitch?

Does it still happen when nothing is connected to the rear inputs at all even though ‘line’ is selected?

Does switching to phono have any effect still without any inputs connected, such as increasing this noise level or LED glitch as compared to ‘line’?

Have you tried looking at the X1850’s digital signal (by way of SPDIF into SPDIF interface or, easier yet, just using the USB) with something like SoundForge’s spectrum analyzer or free spectrum & scope software like TrueRTA? I suggest you also switch to 44.1khz and 48khz to see if the noise is indeed absent on them, but ensure that the computer and software has properly switched sampling rates to match the mixer before coming to any conclusions, of course.

You can. CD players are doing multiple times oversampling since the mid 80s. Its no problem at all, if done correctly it might actually improve precision on good speakers (like I said, all common audio knowledge from the 80s). But you don’t earn information that isnt there before ofc.

Hi Reticuli Never tried it with nothing plugged in, can’t remember for sure when connected to a turntable but I think it was still the same. The background noise is only slight with no music playing.

It only happens when set to 96kz output fine on 48kHz If all 4 inputs are set to line then all 4 flash, if 2 are on line and 2 on digital only the line ones will flash. This mixer is designed to be able to have line and digital inputs work side by side at 96K output.

What I must say is that InMusic have confirmed this is a fault, this is only to make others aware as most have their mixer set at 48 kHz due to other devices connected. I do not connect to any effects. I bought this as one as it went with the two SC6000 I purchased plus it sates it works at 96kHz / 24 bit.

Hi Dj alzy This has nothing to do with distortion it’s a fault in the mixer that’s been confirmed by InMusic. Also I am not trying to upscale, I want the digital copies of vinyl that I make to be as good as I can within my price range. So using Sound forge studio 16 I make all my own digital copies at 196,000kHz @ 24 bit for my Hi-Fi however I resave all these at 96kHz @24 bit for the Denon SC6000s as these and the mixer are designed to work at these sample and bit rates. I just want what it says on the tin (paid for) as they say.

You have moved to another manufacturer now anyway Keith so i wouldn’t worry yourself too much about the problem.

As you say most people will either just leave their mixer on the lower sample rate (as there is barely any difference in sound anyway) or just connect digital devices via a digital specific cable, with record decks connected via the Phono connection (not line as you implied above) so its a complete non-issue for the vast majority of users who are just going to connect their gear business as usual.

Curious. I would think if it’s some sort of fault in 96khz mode that introduces noise into the analog input sections that this would be immediately noticeable on the phono sections that have even more sensitivity, but perhaps it’s just an issue with the line ins? Since you don’t have the mixer anymore, I guess, it would be impossible for you to check this yourself. I would be interested what others find out, though.
