phantom power automatically turned off but the phantom power indicator is working correctly.
please help
Hi
It’s almost impossible to help with such few informations about the issue.
hai sir, thanks for your replay
anyway to get its service manual please
There is no service manual, sorry. Please provide more details about the setup and the problem.
Thank you for your support,
I am using BF pro with cubase 10.5 in windows.
BF pro powered by USB, no extra power supply.
When we switch ON the phantom power, 48v led glowing but voltage not getting on mic and some times OK. Voltage downing not suddenly, it is slowly and some time it return to normal 48v. I have no sure about the phantom power of my RME, thats why I am using additional phantom power in input line between mic and RME XLR inputs.
My mics are rode nt2a and behringer C1.
I checked all the cables, all things are working fine( as I am an electronic technician also)
All other things are working fine.
Please help to solve this
Have you tried another usb port? It may have stopped supplying enough power. If you can try on another computer.
I am already tried it with all usb ports and also with an external power supply.
anybody can help me please
please anybody can help me
You have a correct external power supply with the locking connector and you are able to measure the phantom power correctly (you say you are technician)
The phantom power is not stable, then it looks like defective unit and is a case for the support

That’s also my opinion. Only you have the unit in front of you. Unlike with software related issues in your case it’s almost impossible to help (beside the advice from waedi to contact the RME support).

I absolutely don’t understand what you want to show in the video. For me it looks all ok! It’s normal behaviour after activating the phantom power to have some noise for a few seconds which shows up on the level meters.
More important to know is: does the mic work properly or not?

Thanks for your responce
How do you recognise the phantom power is 'going down' after 2-3 seconds? In the video I cannot see that. And also, how do you recognise the mic is not working?
Do you have the gain opened? Is there a DAW or some other audio app which should receive the signal involved? What can you see in Totalmix?

Thanks Dear,
can u please look on that behringer mic, there is one led for indication, and also my total mix have no input signal.
I checked with multi meter in babyface in put also
Ok, time for repair I guess
if any body have schematic? at least share only that phantom power supply area please
There are no schematics, and I strongly advise against repairs outside of our official channels. The BF Pro can break easily by disassembling without the required expertise. Its 10 layer PCB is also not suited for the general technician. Finally service would first check that the unit is indeed defective, and then give information what to do.

Thank You Dear MC for your response
I did all kind of checking with in my knowledge, can not find any problems in my small set up.
Can you please check my previous messages?.
Also I have not sure about the local service centers, that's why I try to seek the forum advice
Thank You
The forum can not help more. Where are you located?
I am from Kochi, India
Then contact our distributor in India, or RME Trading in Hong Kong.
Thanks for your response, but I have not sure about that. They may be replace the main board.
now it is working with external phantom power. but I like to use its original condition that's why.
Have you tried another microphone to make sure it's not a problem on that side?

The forum can not help if the unit is defective, then it would need repair...
Have you connected the microphones directly now, or is there some other device in between, as your first post indicated?
First time(when I purchased) mic connect directly to BF in put.
but after that phantom power failure, using a separate phantom power between in put and mic
I can understand schematic is confidential, but if I got at least only that phantom power supply area of the schematic, try to self service
Does it work with the external supply? If so, I would just use it like that. As MC pointed out, there is really no way to do DIY repair here.
Thanks All of you for your responses
now it is working perfectly with external phantom power between mic and BF in put.
I dont like to send it to a service center for repairing. hope if I get a service manual I can do the repair. Now I under stand, that is not possible
It sounds like the usb port you are using is not supplying enough power for some reason. Glad a PSU works for you

Not exactly a PSU (this one didn’t solve the issue), but an external phantom power unit between mic and Babyface mic input.
What you could do (if you don't have the equipment) is have some local techician measure the phantom power supply to confirm whether there is an issue.

Yes Dear you are correct now I am using an external phantom power

Thank U dear,
I am already did all check up as I am a electronic technician as well as a musician
