With Ethernet and SNMP capabilities, this 1U rack-mounted unit can be managed through a web browser, allowing you to monitor audio levels in real time and set custom silence thresholds. It even comes with extra GPIO pins for added flexibility and can trigger alerts for other non-networked gear. And if both your main and backup sources fail?
