Hi all,
I'm using WOS 1.3 and I like it very much.
I had some problems (freezing oscilloscope view) on a particular laptop (Lenovo with Realtek soundboard) so I moved it to an Asus Laptop; no more problems.
I noticed that my old Timetrax ticking sensor was picking up a lot of noise from the surrounding ambient, surely related to 50 Hz mains and other sources, like LED lights.
I looked at the cable connections: There were only one "hot" wire and a shield, connected to both the piezo ground side and the plug ground side.
That creates what Audiophiles call a "ground loop", acting as an antenna to pick up the noise.
So I replaced the cable with a good quality shielded Microphone Cable, with two wires inside and a good shield.
The shield was connected ONLY to the plug ground side, and left "floating" at the sensor side; that's the important trick.
Now the noise is reduced to near zero; I checked with an oscilloscope, and by hearing it at the output of the Timetrax amplifier.
Hope that this will help some of you,
Paolo from Italy
