Comes with two option cards: These cards are expensive on their own and I purchased both separately.

AES50 - This allows the conversion of AES50 at 96KHz to AES50 at 48KHz - Ideal for connecting MIDAS pro series consoles to M32/ WING consoles (We used this as a network bridge to run waves on our pro series via an x32 rack)

MADI - This allows the conversion of AES50 at 96KHz or 48KHz to MADI

Unit has been toured extensively and works perfectly. Case has some road rash
