Different volume for phono vs line level

[thumb5]

Yep, the set-up looks OK to me. Tentatively I'd have to conclude that the phono stage isn't providing the gain it's configured for or the cartridge isn't producing the rated output. Either way I'd probably just increase the gain (i.e. reduce the "Max level") in steps until the volume level is better balanced with the other inputs, keeping an eye on the meter to make sure it's not clipping. From what you've said you might end up with the maximum gain (100 uV max level).
