##### tieLight Portal PCIe – tieLight and MADI I/O Card (O\_Serv\_AI\_MADI\_TIE\_a)

The tieLight Portal PCIe card provides optical tieLight and MADI audio I/O together with an external synchronization input.

#### Standards

- MADI interface compliant with **AES10-2008**
- Synchronization interface compliant with **AES11-2009** and the applicable audio and video synchronization standards

#### Audio
