#### Topic: Babyface : Enough power via Phones Out ?

Hi,

I would like to know if my headphones will deliver sufficient sound pressure level when connected to the Babyface. I'm totally lost in converting V/mW/Ohms/dBu... Could you please help me ?

Babyface :

DA Phones 3/4, as DA Line Out, but:

Output impedance: 30 Ohm

Output level at 0 dBFS: +7 dBu

My Headphones (AKG K-702) :

Efficiency: 105 dB SPL/V

Max. input power: 200 mW

Rated impedance: 62 ohms

Q1. What's the max power (in mW) the Babyface is able to deliver via the Phones Out?

Q2. What will be the max sound pressure level (in dB) reached by my headphones connected to the Babyface Phones Out?

Q3. If the max sound pressure level is too low for my taste, can I connect without any risk (except for my ears) my headphones to the DA Line Out to get more power?

Thank you in advance.
