Topic: HELP! Microphone issue RME Fireface 400 UC

Hi all,

I own a RME Fireface UC and I recently bought a RODE NT1-A microphone.
I need to record incoming audio from the microphone into Logic Audio 9 (I'm on a mac, obviously).

• I connected the microphone to the front MIC 1 input
• Turned phantom power on
• Trimmed the gain
• Checked that the mic is routed to AN 1/2 which is my main output

and the result is I hear NOTHING.

Tried to record audio in logic selecting the input 1, I do get some VERY LOW signal that if I normalize results in VERY LOUD background noise and extremely low voice (the shape of the wave file before normalization is so low you can't see anything)

I tried to connect the same microphone to my apogee one and works perfectly so is not defective...

I attach here a screenshot of how my mixer and matrix are configured...

Can't see the screenshot, 404...
What incoming levels does the mixer show? SIncer there is no "400 UC", I assume you mean the Fireface UC?

Do you see level on the meter in channel 1 input row of TotalMix?

I see it only when I touch the gain parameter but is not my voice is something else (noise ecc)

I did test both the mic input with the phantom power off having other sources connected and they seem to work correctly...

Re: HELP! Microphone issue RME Fireface 400 UC

UPDATE:

on a nother forum I got this tip:

"You are using a XLR to XLR cable on the mic, not a XLR to TRS aren't you?
There is no phantom power on the TRS jack, only the XLR so the mic is un-powered if connected via the TRS, and it's sounding more and more like you don't have phantom power reaching the mic."

Is this actually true? I'm using an XLR to TRS but since the front Mic Inputs have neutrik connectors what else am I supposed to use? If that's true what would be the use of having phantom power in the soundcard at all..!?

Re: HELP! Microphone issue RME Fireface 400 UC

To connect microphones with phantom power, please use balanced XLR cables.

Yes, this cable will not work here. You need an XLR-XLR cable (balanced!).

Aren't they combo connectors, accepting both XLR and jack plugs?
