Hello everybody,
I'm new on this forum, following the discussion which is quite technical, you might be of some help, eventhough it's partly related to this thread of discussion.
I moved to a new home and also inheritate of a pair of JBL L300 summit and recuperate a good turntable with a huge collection of LP, so I decided to update my HiFi setup.
I have three sources : the turntable with a radial J33 phono amp, a CD player (Marantz CD67SE) and a computer.
The backbone of the installation will be a RME ADI-2 Pro FS used as a pre-amp/volume control/DAC, collecting the signal :
- from the PC on the USB
- from the turntable on the XLR analog input
- from the CD player through SPDIF optical
My question is related to the amp that will be a AUDIOPHONICS HPA-S400ET based on the Purifi module.
As far as understood their is an interface card (installed by AUDIOPHONICS) providing a selectable input gain that can be bypass.
So my first question is that if I set up the ADI-2-PRO-FS to provide +24dBu @0dBFS on the Analog output, I should be in the range of output voltage perfect to bypass the interface card from Audiophonics, am I right?
Second question, Do you have any idea of the good selection of input gain on the analog input of the RME to fit with the XLR ouput of the phone amp (spec Balanced outputs 600Ω, -60dB mic-level)? +24 dBu, +19 dBu, +13 dBu, +4 dBu @ 0 dBFS ?
It's not always clear with all those differents units.
You might say, just test... but I would prefer avoid blowing my speaker with a setup with to high gain...
Thanks in advance for your answers.
