Sound distorted with analogue outputs 3 and 4


Hi, Suddenly my DS1 started to output distorted sound from analogue outputs 3 and 4 (deck 2, the right deck in Serato). I have tried every possible thing to solve this:

  • Tried with different audio/usb cables.
  • Tried with different software.
  • Tried with different computer.
  • Tried different mixer. If you load the same song in both decks, the 3 and 4 analogue outputs always sound distorted or near to distorted compared with analogue outputs 1 and 2. If you lower the gain a lot, the problem seems to be gone, but if you use normal gain levels (or autogain), 3 and 4 are always distorted. ¿Is there some kind of known issue with this? BTW, I tried to upgrade the firmware because I saw that latest version in the website was 1.0.1, but when I tried do upgrade, the upgrade utility says that it is not possible because I have a newer version that is 1.0.5 How can I have a newer version than the one that it’s avaliable in the website? I’m using a Mac Mini and a Macbook Pro, both with Sierra, i5 processor and 16gb of ram.


Remember that the DS1 also has a line/phono level switch on it. This is to allow it to be used with vinyl record decks, which give out very quiet signals), or Line Level, which are significantly louder.

If loud sources are played into devices which are only expecting very quiet signals, then the sound passing through will sound terribly distorted.


The problem is not with the inputs, in fact I don’t use the inputs because I use internal mode. The problem is with the outputs. Lowering the Master level on Serato seems to avoid the problem, but I don’t understand why is happening this only with outs 3 and 4.


Check for input level change switches where the 3&4 outputs go into


Input levels are right, using same tracks, same gains, same everything than 1&2, the problem exists if the master level of serato is over 1/3 or less… 1&2 sounds right, 3&4 sounds distorted. Lowering to zero the master level solves the problem but this is not a usual behaviour, and lowering the master level also gives mucho more less signal on the two outputs.
