The Model 44D from Studio Technologies is designed to interface between analog audio and dante networking technology.

The Model 44D Audio Interface supports Dante Audio-over-Ethernet media networking technology and provides two analog line-level inputs and two analog line-level outputs. Also includes two installer-accessible general-purpose inputs (GPI) and general-purpose outputs (GPO). Designed to add Dante inter-connectivity to analog ports associated with 4-wire matrix intercom systems. Can also serve as a dual-channel analog input/output interface for various applications. Housed in a lightweight "1/2-rack" enclosure with optional rack-mounting front panels. Can be powered by Power-over-Ethernet (PoE) or an external source of 12 Vdc, purchased separately.
