Default M-Audio Firewire Series Input Levels

What are the line input levels for the M-Audio Firewire series? I've heard that they are consumer (-10 dbv) and that a pro line level input (+4 dbv) is too hot.

The documentation is silent on the subject, and I haven't been able to get an answer in the M-Audio forums, so I thought I'd try here.

Default Re: M-Audio Firewire Series Input Levels

From what I'm reading, they're all pro level (+4).

For instance, the 2626 lists a max input of 19.6dBu, which is about 7.5 volts, well above the reference level of 1.223 volts at +4.

The ProFire 610 is listed at 16.xdBu...so not much different.

M-Audio Tech Support finally came back and said:

The line inputs are unbalanced and therefore -10.
Now, not all unbalanced inputs are -10, but apparently that's the answer for the Firewire 410.

Yes, you're correct - I hadn't looked specifically at the 410 and made some assumptions.

The 410 seems to be the exception with all inputs being -10. The 610 instrument inputs are -10, but the line inputs are +4.
