Additional features include: An integrated digital to analog converter with balanced stereo and headphone outputs, front panel controls, XLR AES input and output jacks, dip-switch selection of silence detection of -20, -25, -30 and -35db below zero reference; precise alarm timing delay from off to 85 minutes; precise restore timing delay from off to 10.2 minutes.
Overview
(DISCONTINUED)
The AES Silence Sentinel® Standard is designed to monitor an AES/EBU digital audio signal for silence or an out of phase audio condition, generate alarms, and transparently switch to a back-up AES/EBU audio source. Signal bypass is built-in with AES input one passively routing to the AES output in the event of power loss.
