This compact 2U rack-mount universal converter, the "Universal Format Converter" (UFC) in name and error-free performance, can simultaneously transfer 24 tracks of PD, SDIF-2, ADAT, TDIF-1, and AES/EBU. I used it actively until the year before last, but have been storing it in a barn since I closed my studio. The power turns on, of course, and the buttons operate crisply. Unfortunately, I no longer have the operating environment for the large digital mixer it was originally connected to, so I'm afraid I'll have to list it as junk. Used, untested units of this type sell for around 300-500 USD, so this one is in considerably better condition, and since it was originally working, it's a better option than unknown-origin junk. - Model Name: UFC-24 - Brand: OTARI - Type: Universal Format Converter - Input Terminals: Supports various input formats - Output Terminals: Supports various output formats - Routing Function: Equipped with a routing map Thank you for viewing.
