PS Audio GCPH and Pass X0.2 not talking?

I am baffled. My VPI Scoutmaster 'table works. My PS Audio GCPH phono preamp works. My Pass X0.2 preamp works. But when I plug the GCPH into the X0.2...nothing. No sound. No signal. (The lights are all on, but no one seems to be home.) I've quadruple checked everything from cables to inputs, but can't figure out why nothing is coming out of the X0.2 from the GCPH.

What I am doing wrong?

I'd give Pass Labs a call. Assuming that you are using RCA's from your phono preamp to X O.2, did you use Pass's shorting pins in the XLR's? Looking at the unit from the rear, each shorting pin should angle to the right. In other words, from the bottom XLR hole to the top right XLR hole. If the shorting pins are reversed, there is no sound.

what type of connection are you using to hook GCPH up to:
1) headphone amp
2) power amp
3) preamp

Is it the same type of connection, i.e RCA or XLR in all 3 cases?

Audiomax,

Thanks for the suggestion of using a volt meter. I'll see if I can find one at Radio Shack.

Stan,

I'm in touch with Kent at Pass. So far, he's pretty baffled, too. Contacted PS Audio, as well, and they haven't a clue.

Audiophile,

I tried scenarios using single-end as well as balanced (when possible). Everything seemed to function either way. So, RCA from GCPH-to-RCA into headphone amp was OK; balanced from GCPH-to-balanced into power amp, also OK.

What was the signal source when you tested the GCPH directly into the power amp?

With the GCPH into the X 0.2, what gain settings did you use on the GCPH and on the X 0.2?

Have you tried more than one input on the X 0.2?

Really stupid question: Did you have the correct input selected on the X 0.2?

There's nothing magic about the output signal of the GCPH - it's just another line level signal.
