Topic: RME Babyface (Old) Phones-out as Line-out
Hello, I'm new to this forum. I have used the RME babyface for quite some time now and i love it.
I have a question which i think apply to the new babyface pro interface as well as this older one i use, I just recently bought a headphone amplifier (Aune X7S) that i have hooked up using the phones output on the breakout cable using a TRS to dual RCA cable.
I am a little unsure about what is going on in TotalMix FX, I want to control the volume using my headphone amp's knob and not the babyface attenuator. Leaving PH 3/4 at 0 (max) seems to give the headphone amp a bit too much power when i adjust the volume just slightly on the amp, and even on the lowest volume possible, there is still the tiniest amount of sound still audible.
Only when i reduce the PH 3/4 hardware output by -20db in TotalMix does the volume seem reasonable on the amp, but I'm not sure if this is accurate volume. So is there double-amplification going on here due to how the headphone circuitry works? I know it says in the manual that the phones-out can be used as line-outs.
I use K712 headphones, I don't have a lot of experience hooking up equipment aside from studio monitors and some microphones.
Thanks for any replies.
