It will work if the ATs are configured to be 2-wire, with the pair connected to a stereo TRS mini-plug. That's how they are commonly used around here, how Darktrain does them, Sound Pros, etc.
It will not work if the ATs are configured as 3-wire, which is how they are supplied from AT. You'd need either 3-wire to 2-wire adapters or a 3-wire batterybox or preamp rather than a standard 2-wire CA9200.
