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

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.

If you look at the Aleph 5 schematic in which the RCA/XLR configuration is similar to his XA60.5. Having the connector hanging without a cable connected doesn't make much difference. All the jumper does is effectively puts a ground on one side of the input differential pair so you can use the single ended input.
