Description & Applications:
Provides two general-purpose outputs (GPO) that respond to the presence of high-frequency audio signals in associated Dante receiver (input) channels. GPO functions can also be enabled using front-panel pushbutton switches, by way of software-controlled “virtual” pushbutton switches, or network-associated UDP commands. GPO functions can be configured as logic (current sink) or DC voltage outputs. Model 395 units can be utilized in broadcast, theater, industrial, and aerospace applications
