About: Studio Technologies Model 44D Dante Audio Interface

The Model 44D Audio Interface provides a simple yet high-performance means of interfacing two channels of analog line-level audio to and from applications that utilize Dante® audio-over-Ethernet media networking technology. Two Model 44D units can also provide one-to-one signal paths, two in each direction, over a standard local area network (LAN). In addition, the unit supports transport of status signals or contact closures between Model 44D units and other compatible products. There are two general-purpose inputs (GPI) and two general-purpose output (GPO) on each Model 44D.

A special operating mode allows the Model 44D to serve as a tone generator rather than an audio interface. When configured for the tone generator mode 18 kHz and 20 kHz sine-wave audio signals are available in both the analog and digital domains.
