According to the specs EIN is -127 dBu. I assume this
is A-weighted (it doesn't say). Not really spectacular
but not a disaster either, if true.

Also according to the specs, max input without pad is
+8.5 dBu, and gain range is 50 dB. So 0 dBFS at max
gain should be -41.5 dBu at the input.

Combining this with the given EIN, you should
measure -85.5 dBFS(A).

I guess that the -61 dBFS is even without DC filter,
a classic mistake.
