Unfortunately, Windows does not support multiple simultaneous USB audio interfaces. And I'm not sure about the A&H USB port (no ASIO driver that I could find; not even sure if it's Class Compliant). You may need to feed the A&H's S1 Line Outs to the Focusrite Scarlett Line Ins to get it into SONAR.
If you don't think it's possible to get a high quality recording of a group from even a single mic, check out the Benny Goodman "Live at Carnegie Hall" double CD. The band that night (16 Jan 1938) included Count Basie, Teddy Wilson, Lionel Hampton, Bobby Hackett, Johnny Hodges, Harry Carney, Cootie Williams, Freddie Green, Walter Page, Lester Young, Buck Clayton, Harry James, Gene Kruppa, Vernon Brown, and vocals by Martha Tilton.
What a lineup! All recorded through a single overhead mic and piped directly to CBS Radio.
It can be done! Good luck!
