Asus z97 Pro - Crystal Sound 2, Headphone AMP suppport

post #1 of 3
Thread Starter 
Hi everyone !

Does anyone know how many ohms the z97 pro can handle ? From what i can tell from the Asus website & manual, the board does have an Op Amp but no specs on it whatsoever.

http://www.asus.com/Motherboards/Z97PRO/ - Audio amplifier Enhances the highest quality sound for headphone and speakers

For example, the z97 Pro gamer lists the OP Amp and the max value it can drive

http://www.asus.com/Motherboards/Z97PRO_GAMER/ -- 300Ω-headphone amplifier Z97-PRO GAMER drives some of the very best headphones available — up to 300Ω load impedance

Thanks !

If you go the the Realtek site there are specs for their chips.

Went here : http://www.realtek.com.tw/products/productsView.aspx?Langid=1&PFid=28&Level=5&Conn=4&ProdID=328

Managed to find nothing frown.gif

Found this thing however : http://www.hardwaresecrets.com/datasheets/ALC1150-CG_DataSheet_1.0.pdf

Output Impedance :

- Amplified : 2 ohms
- Non amplified : 200 ohms

This still doesn't give me any information regarding the amp asus put on the board tho frown.gif
