[solved] Bass Drum BUZZZ

Discuss Nava construction and related issues
  • Bump!
    Anyone ?
  • i didn't notice this before o_O but i also have a buzz on the bass drum (main out and single out), its also to quiet compared to other instruments...
  • Same with my BD, its also to quiet compared to other instruments
    Maybe some errors in PCB design?
  • ok, at least some others also have the same problem, so there might hopefully be a bigger chance that we get at least a little bit of support..
  • I'm comparing Nava and r909 schematics
    Maybe some errors
    I checked my Nava with scope and it look like some buzz coming from IC11 pin 3
    is anybody have pictures with traces?
  • IC11 pin 3 is connected to ground..
  • yes, i know
    I checked this pin with scope
    some news
    If remove IC33 and ic32 no Buzz on scope
    Maybe some errors in Noise section
  • What cd4006 in your nava?
    I used rare toshiba
  • I removed one leg of r10 (input of noise) and the buzz was still there. I have to check tomorrow which 4006 I used..
