HI. So I bought a ********* ADA8200 8 In/8 Out ADAT Audio Interface with MIDAS Mic Preamplifiers but can't seem to get it to talk to my 1824c. The interface is working, preamps are getting signal, nothing through headphones, nothing in Protools. I've tried both as slave and as master, but still nothing. Get sound from the interface preamp, but nothing via adat.
