The PC32-IFC05 from Apogee is a 0.5 meter, proprietary cable for connecting the Symphony PCI card with an Apogee interface that is equipped with a Symphony-X card.
The cable can also be used to daisy-chain interfaces where multiple interfaces are connected to a single Symphony PCI card. Interfaces that are compatible with the Symphony system include the AD-16X, DA-16X, Rosetta 800 and Rosetta 200.
