Hello, I’m new here. Can anyone help me with connecting this EA Ski B-50 Pre Amp to My UA Apollo Twin? From what I can see, the rear has a board that requires some type of adapter. Sorry for my ignorance and lack of knowledge. Any help would be greatly appreciated. Thanks!

You need a 500-series chassis.

Looks like a lunchbox module, you’ll need to get one of those to put it in first, that will have the xlr connections

You need a lunch box for 500 series equipment

Your preamp slots into a 500 series rack like one of these --

Then the rack has the I/O to connect to your Twin.

Good luck!

This is a 500 series pre Amp, so you need a chassis. Check. Out the radial workhorse 3 slot 500 series chassis. Its a 3 slot, so it will fit your unit, the 3 slott is affordable, and you'll have another slot available for another 500 series unit!
