Topic: Headphone output in RME 9632

Hello, I don't know if it's normal, but when I plug headphone with 250 ohm impedance to headphone output in breakout cable, the sound is very very laud, on -12 db setup in "RME mixer". I don't know what to do. I wrote in main site RME 9632 specification  that RME 9632 has 75 ohm impedance output for phones, but when I opened manual pdf file, than I saw that that's card has 50 ohm impendance? So , someone wrote two diffrent spec!! Also, in my problem, I think that card does't have 50 ohm, and 75 ohm, but it sound like 300 ohm! What's going on???

Lower the output volume in your host or in TotalMix ...

What kind of headphones are these? What's their sensitivity?

Re: Headphone output in RME 9632

Spec of headphones SPL: 97 dB, max output: 100mW, 250 ohm (I don't know how it say this app- but in main window, when I can choose latency, I have to turn down there headphone output on -12 db)

And today:
Also I've checked another one headphone: SPL : 106 dB and 63 ohm. The situation is the worse: I have to turn down also in windows mixer at 5 %, than is enough to listen any mp3 file. (I don't know how it say this app- but in main window, when I can choose latency, I have to turn down there headphone output on -12 db)

Re: Headphone output in RME 9632

And other question -on this site: http://www.rme-audio.de/en_products_hdsp_9632.php, I've read "Low impedance headphone output (75 ohm), stepless output level through software faders", but in manual 9632 pdf. file on rme site I've read "output impedance: 50 ohm".
What is true???

I'm using 250 Ohm Beyerdynamic DT 990 Pro and don't have problems with it ...
