Hi guys,
I can't recall which pot one may turn to adjsut DC Offset on UcD400HG. The main PCB one or the black coated one?
thanks !

Hi guys,
I am using a Hypex module UcD400HG (with HxR voltage regulators) and SMPS400. Recently, almost every time I turn it on - one of the HxR regulators refuses to start (the red LEDs stay dark) and so the amplifier remains silent. I need to turn the supply on/off multiple times until both HxR regulators successfully start.
I have not contacted their support yet (don't know if they will bother to answer). Has anyone experienced something like this, any ideas for fixing?

I do think they will answer.
They helped me to try to fix mine even if they won't do the work for you. They may point some parts for you to check and give specs of parts if needed. Give them as much details as you can such as boards version or setup (dual mono, wiring weirdness or such...) in your mail. Good luck in fixing it. (tried all I can but mine is in Class D heaven now).

@Malefoda Indeed, they did answer. They asked me about the QR code of the amplifier to check if there are similar complaints for the same batch. Unfortunately there were not and the support had no clue why my module refuses to start. So they sent me the schematic, in case I decide to unsolder the HxR module and bypass it.
I will probably finally unpack my old package with VSSA amplifier kit and find some time to bring it to life.
