Very poor sound quality

[melkker]

Yes they are in phono position.

I did not quite clearely understand what you asked for, but u46mk2 version is 1.0.41 or f/w 2.2.3

Crackles come with a latency too low of the sound card, set your sound card to 256 samples for this setup (6ms). Your computer is loosing the syncro with the audio data.

Which type of turntables do you have? Are they in phono riaa or line output?
They don't seem to be well detected.

Hi,

I will try with the 256 sample version today evening, maybe it has some improvement now. I have tried every sample rate and every possibility before.
Yesterday I played for a few hours and after approximately a hour it did not make any sudden overruns or delays(like computer gets sudden overload and after that starts to compensate and speeds up the soundfile. Something similar to watching movies from slow computer, picture is running fast to meet the sound.).
Maybe there are some programs on startup, that does not communicate well with mixvibes or uses same resources and after some use they relax.

I have Numark TT200-s, they are RCA phono

I just tried with 256smpl rate. As I thought, no difference at all, maybe for the worse. Because these crackles are present and sound gets really crackly and speeds track up for some moments.

set your vinyl options preamp to 4db both sides. click on apply
Publish again a config report you don't have a good reception of codes or the setup fail.

in green what is ok
in red what is wrong (no detection of time code)

[melkker]

thank you for pointing out the problem, but what should I do to fix it?

[UncleVibes]

see if the problem occurs if you plug deck2 in place of deck1
Vinyl options:
See also if you need to check the combo box inv phase. (click apply each time)
If the same problem appears with no solution then it's your turntable in question...
I am sorry it's all I can do with the elements I got. Check that the incoming signal doesn't saturate in the vinyl options. Check also the mixer of your sound card.

[melkker]

I got these numbers now to appear
I did not know you have to make the conf report with both tables playing.
