Default Pass Labs x2.5 volume control question

Hello Everyone,

While looking at internal photos of current Pass Labs hardware, I was wondering what attenuator circuit is used in the X2.5?

http://www.passlabs.com/images/product/x2-5in.jpg

I would have thought a resistor and relay ladder network would have been visible such as in the X1.

A ladder network was not obivous to me from the x2.5 photo. Just wondering how the x2.5 attenuation works.

Thanks!

-David

There are some connectors on the mainboard, so it looks like the stacked PCBs are removed in your photo of the X2.5
