Question about Bass Management in Classe' Sigma SSP


I'm interested in the Classe' Sigma SSP. Can someone please tell me about the Bass Management functions of this unit? I am particularly interested in knowing what crossover slope settings are available in both the high pass section and in the low pass section.
My current processor is a B&K REF30 that is getting a bit long in the tooth and may need replacement soon. I do like its bass management section though.

In the High pass section i can choose either a 6db or 12db per octave slope.In the Low pass section i can choose slopes of 6,12, or 24, db per octave.

What are the choices in the Sigma SSP?  I read the manual online but it doesn't detail what slopes are available.

Thanks!

A follow up question if i may. 

I was wondering if you have the ability to change ( invert ) the subwoofer phase in the SSP?
The Speaker configs can be PER input(There are 6 different configurations), and inputs assigned to those configurations

Bass management is down to 40hz at the crossover points(in 10 hz increments), and then 12/24 for the subwoofer crossover point.
And Manual PEQ bands for each channel
