Don't the Pass XP preamps have selectable gain?

Tony,
I just compare the XP-20 manual which I received with my preamp to the online manual from the Pass Labs website. They are not the same document. In my manual, there is a paragraph located between the "Theater pass through" section and the "Electronic volume control" section which describes in good detail what the gain settings are. I quoted from this section in my post above. For some reason, it does not appear in the on-line manual. There are also other differences between the two manuals.

Hmm, I don't suppose one of them is the mentioning of a mono switch? :-)

Nope. I agree. My old X-1 had a mono switch.

Tony,
Some of the XPs have selectable gain, some don't. I just talked to Pass. You should contact them. They are most helpful on the phone or via email.

I just had some mail conversation with Pass concerning some issues of the XP 20. The topic of this thread was also covered:

"Early piece had two gain steps (High gain and Low Gain) This was envisioned as a simple answer to source components with wild differing gain.
With the high gain / low gain option a simple toggle of the gain setting allowed the preamp to run at about the same volume settings with a wide variety of souces.
This proved difficult with our Asian clients and the latter unit was simply given enough volume steps to cover the entire range ..."
