Hand Clap Sound problem

Discuss Yocto construction and related issues
  • Dear logium,

    It seems that you need to calibrate the Cowbell.
    For the Clap, could you post a picture of your build, that i could check if you made a mistake.

  • All other functions are working well but the problem is the CB and HC. I put some pictures here: https://www.dropbox.com/sh/6jr5u9q7oniz2eh/4sQTEE64W-

    If the CB does'nt have a trimmer how to calibrate?

    CB trimmer are the 2 trimmer on left hand.. (but you have to set before 130mV AC for the noise trimmer (noise gain)
    handclap in the middle of the board.
    noise on the right hand.

  • Thank you!

    same issue by me before i doublechecked all resistors.
    trim your TM3 to full left - you must hear a empty reverb - full right only a noise, arround the middle a clap.
    do you have a scope for measurement ?
  • no, I don't have scope I need to borrow a friend. Here you can listen to how the sounds TM3 full left is it same like you had?

    one case was heard as the clap but this change quickly. At first I suspected that the cold soldered. I found no such connection.
  • Dear logium,

    Download http://www.zeitnitz.eu/scope/scope_141.exe software. It's a scope sound card and make the test describe on this topic
    Post your result it will help me to solve your problem.

  • Thanks, it's a good opportunity without SCOP. Before I take scope I checked to measure the noise and was not able to get a 130mV tuning the trimmer. only 3.6mV (i don't know what does it mean). after checking resistors in noise area i found that the resistors R130 is not 1M (only 54K). Is it possible it was corrupted.
  • Everything works, even a HandClap. All resistors were correct but I soldered resistors around BA6110 all over again, and it worked. :)
