Buzzing Naomi NOW SOLVED

Post by Red5 » April 8th, 2011, 9:54 am

strange one this
When i try and use ANY Naomi 1 mob, i get a loud buzzing noise from the speakers.

Tested:
Sound amp and speakers work 100% (used 3 different input sources 100% working zero hum buz)
checked all Earth wires and connections
Taken audio feed from MOB to another amp, i get the same Buzzing fault, as this issue shows on 2 different MOBS, i am thinking that there may be a issue with the SUN psu?

whats else can i try, :think: borrowing a different psu to eleminate it.

I don't know the answer but I get the same thing from my Naomi setup when I route it through a cheap 12V amp to the cab speakers (this is in an Egret II).

All sorted now, thanks to me old m8 tetsujin,
i already had 2 naomi 1 Mobs's , adam brought along a 3rd and a New filter board
First we replaced / changed any wiring we could, even a different Sun psu, no joy, after many hours head scratching later the last thing we tried was a replacement filter board on one of the mobs, (i dont know if its brand new but certainly look'd shinny and clean) success, no more buzzing.

Just goes to show, took a 4th filter board to solve the issue :twisted:
