Here is the reply from Cristian, thank you all:
Hello Angel,
Thank you for the feedback.
About the recent units of La Scala MKII Optologic, there is no issue to use RCA and XLR at same time, since the XLR as true balanced (and NOT differential) signal with floating ground (passive transformer with HOT(+) and COLD(-) / no ground).
With the true balanced analog circuitry (fully floating) of the La Scala MkII Optologic we obtained several advantages, for example in the impact of the second harmonic (differential cancels the even harmonics), and the floating Ground (as Professional standard).
- True balanced (and NOT differential) signal with floating ground (passive transformer with HOT(+) and COLD(-) / no ground). Connection used in professional, like STUDER, to be clear.
Pin 1: Signal ground
Pin 2: Signal + (non-inverting)
Pin 3: Signal - (inverting)
Connector ground lug: chassis free
Kind regards,
Cristian Anelli
