Microphone recording extremelly low

[Zeh]

Hi All,

I opened one topic in january (Help to recording with Condenser mic - linked below). Today I began the recording session. I tried to do all the things suggested but still not working.

I saw another topic with the same issue (linked below). Read all suggestions and tried all... still not working. My interface is a Behringer U-Phoria UMC202HD. I really tried and observe everything mentioned (Phantom, Cables, Line/instrm, fades, inputs, different mics, etc). My situation is worse than @ShenA once my graphic shows almost nothing. After I enter in the INFO - track region and add +30db the graph shows a very small wave that seems square. I attach the prtscr that shows this.

Any help will be useful.

PS: I don't have another audio interface to test.

Thanks all

Hi All,

I had just changed the Audio interface to my laptop and worked. So the problem seems to be on USB port or some desktop configuration.

@Sheanot sure if you solved your problem but try to change the USB port.

In the next day (today) the same problem happened. I looked for behringers Audio interface Driver to mac but doesn t exists.

I use High Sierra and can not update the OS (incompatibility with plugins and programs that I use). So I m not sure which is the problem but it s something related to the configuration. 
 

Does anyone has a tip on this problem?

What are you trying to record? The waveform looks very strange, like there's a phase issue, almost like the wrong cable.

I agree with @triplets - that waveform looks wrong.

So you get that exact same problem with two different audio interfaces? Are they the same model or different models? Can you list the exact set up, I mean which mic, audio interface, and what settings you're using (phantom power on/off, preamp on mic/inst/line, how you've dialed the gain...)?

Hi,

sorry. Maybe i express myself badly. The problem happened with the same interface. But now I m sure that interface is working.

My set is a Mac Pro (2010) with High Sierra , audio interface Behringer UMC 202HD, the mic is a condenser (Blue Bird SL). And I was recording voice and acoustic guitar. 

Since yesterday, everytime i turn on the mac, I have to change the USB port. it really seems a USB port issue  when I change works..but everytime I turn on the mac the interface does not record (even though It reproduces sounds ok). The problem is obly to record  

The settings are as expected: phantom power on, etc. I really take a look in all comments and checked Everything. 

The problem seems to be with USB Port. Not a physicall issue because, eg: i move from port 1 to 2 and works. When i turn on the mac later, is not working. So I move back to port 1 and works again. Really strange. 

i reboot mac manytimes, but it s always the same issue.

Are you using the USB front ports or the rear ports?

[Zeh]

I always uses the rear ports. 
 

i m not sure if I made myself clear once the problem is intermitent.
 

As an example I ll describe what I m doing nowadays. 

I have ports (rear) A and B. Let’s say that audio interface is connected in Port A. When I turn on the mac the interface will be identified by mac and output sounds are ok, but record is extremelly low. I can t even see the wave form (only after I add 30Db - it appears and still very low). To “solve” that
I turn off the mac and change the connection to port B. Doing this, recording will works normally. 

But if I turn off and turn on again, recording will show the same problem. So I have to disconect the interface from Port B, and reconnect to Port A. 
 

it s not so easy as I described because sometimes I have to turn on and off few times until it works. And it s not a problem on one USB port once the same Port that works today, doesn’t works tomorrow  

I m still lose on how to solve that  

 

thanks all

Did you try the front ports to see if it's a system issue or rear ports issue?

I tried all ports (rear and front) and use whatever works. Everytime I have the problem (and the problem happened in The front too) I change.

Before you switch ports, look in Logic's audio preferences, under input device, to see if your interface is still connected and if its name is not in between parenthesis, or if the interface isn't listed twice?
