Manual | Diagram | Pricing
Product Overview

The AES Switcher Sentinel 2+1 is a web-enabled three channel AES/EBU silence monitor combined with an integrated 3×1 AES switcher. It is designed to monitor two AES audio sources and one analog to digital (ADC) audio source. When silence is detected on the primary AES input it can automatically switch to the back-up AES input or the backup ADC input via mechanical latching relays. The AES Switcher Sentinel 2+1 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 the product using a desktop web browser or web-enabled mobile device. 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 STARTTLS 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.
