Hi!
Not sure if this question has been answered before here but Google won't help me.
I'm using the Cosmos ADC Iso to digitize LP.
Phono preamp is a Pro-ject Phono Box DS3 B connected to the Cosmos ADC with XLR cables. Phono cartridge is a Clearaudio Concept V2 MM with 3.3 mV output. Gain on the preamp phono stage is set on 45 dB so 51 dB with the XLR output. That means output voltage is of 1170.88 mV.
Impedance source should be somewhere between 100 Ohms and 600 Ohms (I can't find the exact specs of the output impedance on the Phono Box DS3 B).
My question is: what would be the optimal input range / impedance for that system? It's currently set up on 4.5Vrms / 1.66kΩ.
My guess is that I should go for the highest input range / impedance (10Vrms / 3.48kΩ) but won't I lose sensitivity and dynamic range with this settings? Before messing with the parameters I would rather take some advice.
Thanks
