connecting a line stage + phonostage to pass amps

Hi all

I dont know whether this question is silly or not but here it is:

I have Pass xa60.5 monoblocks fed by a first sound pre (linestage only)with RCA IC and now i went also analogue and i'm using a PS audio GCPH phonostage with XLR cables to the Pass. Can I connect both the linestage and the phonostage to the amps ?
Do I need to turn off the CD player when the turntable is playing ?
Thanks
D

If the amp has a switch changing the input from RCA, to XLR, most likely it will be fine.
If both RCA and XLR are fully connected 100% of the time on the amp, then not a good idea.
The signal from one source will go back to the other source, and that usually is bad for the turned off souurce output devices...

Does the phono sound better on its own, instead of run through the preamp? Or are you just wanting to take advantage of the XLR outputs?

In short, you can not plug both XLR's and RCA plug into the XA60.5 simultaneously. If you plan to use the RCA plugs there must be a shorting bar between pins 1 and 3 on the XLR input connector. If you wish to use an XLR input the shorting bar must be removed. Reference the user manual. I have a X350.5 and it works the same way.
