Product Overview

The AES Switcher Sentinel 3+1 USB is a web-enabled five channel AES/EBU silence monitor combined with an integrated 5×1 AES switcher. It is designed to monitor three AES audio sources, one analog to digital (ADC), and one external USB audio source. When silence, out-of-phase condition, or AES error is detected on the primary AES input it can automatically switch to the next available backup input. Switching is accomplished via mechanical latching gold contact relays. The AES Switcher Sentinel 3+1 USB can be configured and monitored locally and/or remotely over any IP network, including private networks, IP-based industrial control networks, and the Internet 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.
