Hello.
Has anyone have Fosi ZA3 stereo amp that has background noise when it is connected with XLR Balanced connection?
I recenty got Fosi ZA3 stereo amplifier and it works fine with RCA unbalanced connection but when I connect it with XLR balanced connection, it has weird background noise. It gets louder when volume gets higher. I made quick recording of it. Can anyone tell me what may cause this noise and is there any remedy for it or it is abnormal and need to ask for replacement under warranty?

I tested it again today and somehow, the weird noise disappeared. I will continue monitoring but at this stage, i think that issue has resolved by itself at the moment.
Issues don’t solve themselves. Probably one of the variables has changed. Like the unknown source, a reversed mains power plug or similar.
No one can say anything really useful when you do not mention the source/setup. Also others that may have the same Fosi ZA3 amplifier likely have different sources but they can not comment as they don’t know if your source is the same as theirs.

My two main sources are Wiim Pro Plus and Fosi Audio Box X5 Phono. Nothing has changed from my source or power source but somehow weird noise disappeared. I might monitor how it goes next few days if the issue come back again.
Maybe I am too thick to understand but both sources are RCA only aren’t they? You stated the issue happened when using XLR…
Yes, both have RCA out only. I use one source with RCA to RCA and another sources RCA to XLR cable so I can toggle between two sources without needing external Preamp or Input selector. It is somehow working fine at the moment without noise either source.
