I've bought some of these AX3797 and AX3798 modules recently.
They look to me like together they could form a sub mixer (5 channel mono to single stereo).
I saw references to other AX modules being "Audience miXers."
The preamps have partial discrete analogue front ends with an on-board minature transformer feeding dual (balanced) long-tailed pairs with a programmable current sink. Looks like that was a common design block on the Q series as I've seen that sort of layout on other cards.
I've made a start at tracing out the pins and schematic, and I think I can work it all out myself although it will take time.
3797 has 3 input channels with L+R bus & mono PFL out. Although it'll be simple to tap the output of the 3 channels separately before the pan pot.
3798 has 2 input channels and one stereo output.
Anyone else interested in the information?
Work so far attached, which I think covers all the major audio and power connections, but I can tidy it up if anyone is truly interested.
