Default Pass Labs X350 - Jumper Position

Recently I bought Pass Labs X350 & X0, I had noticed when I open top cover of the X350 jumpers not in position? When I compared to another X350 pictures from the internet, different position from my power amp. Any one clarifies which one is correct? What is the different between? Note: On the picture right side is my amp. Thanks in advance! Raj

If you remove all 4 jumpers the inputs are ac-coupled via 4 x 100u//0.047u.
On the left picture the amp is dc-coupled, on the right picture it is ac-coupled. The dc-position is printed on the board.

A little tread-jack: Can somebody please measure the DC-voltage (over supply-caps) on a 350 / 350.5 ?
