The AES Switcher Sentinel 4 XLR is a web-enabled, zero latency, transparent four input, one output switcher/router with mechanical latching relays designed to pass AES/EBU digital audio. The AES Switcher Sentinel 4 XLR is perfect for passive AES signal switching via front panel controls, web browser controls, contact closures, TCP commands, and SNMP.

When silence and/or out-of-phase audio is detected on the AES output it can automatically switch to a different AES input. The AES inputs/output feature XLR jacks. Switching is accomplished via mechanical latching gold contact relays, which means that the unit can route a signal in either direction or will keep routing signal even after losing power.

AES Switcher Sentinel 4 XLR can be configured and monitored locally and/or remotely over any IP network, including private networks, IP-based industrial control networks, and the Internet. Users can operate this product using a desktop web browser or web-enabled (HTML5) mobile device. App Store not required. Email notification may be configured to alert up to eight recipients when silence or out of phase audio is detected. SMTP username and passwords using SSL/TLS (Gmail etc.) or Base64 authentication are supported. SNMP traps and SET/GET are built in to allow multiple units to be monitored and configured with SNMP management software.
