Hello,
I need your help for xtant 4180c amplifier bias setting.
I found two trimmer, and i don't know which one is the correct trimmer of bias setting.
Thanks in advance 🙂

I don't have anything on that amp but on other Xtant amps, one is DC offset and the other is bias (likely near the output transistors). If the amp is functioning normally, turning each one and watching the idle current and DC offset across the speaker terminals will tell you which is which.
Hi Perry, thank you, i have found.I don't have anything on that amp but on other Xtant amps, one is DC offset and the other is bias (likely near the output transistors).

There are sets to the minimum regulation, can be ok for you? I have 5.2A current idle operation, don't is strange?
Sorry Perry, my english is very bad 🙁I'm sorry but I don't understand your questions.
I have found two shorted device on front/left channel, i was 5A on idle operation, for this devices problem. Now i have 2A idle operation, and now work fine, thanks
