HELP NEEDED...Noise from a 4 channel B1 buffer with Biino MK2 volume control...
Hi everybody... First of all, please forgive my bad english...
I would ask advice about a nasty hum problem I have from a 4 channels B1 buffer with two Biino volume control boards I built...
I tried various wiring ways to improve but none worked...
The situation now is what (maybe) you can see from the weird drawing here...
Can you see something absolutely wrong that could cause gnd loops or something?
I used a gnd loop breaker between psu star ground and earth/chassis...
Thank you so much!
PS. The Biino is a relay attenuator you can see here:
