The Broadcast Tools MSRP-3 NET is a three station analog stereo EAS relay/switcher with TCP/UDP Ethernet control, following in the footsteps of the original Multi-Station Relay Panel (MSRP) designed by Broadcast Tools for the Sage ENDEC in 1996. The MSRP-3 NET provides additional alert audio distribution and transparent audio interrupt switching for the Sage ENDEC and other EAS encoders. Together with the single balanced stereo switched audio interrupt relay built into the ENDEC, an ENDEC and MSRP-3 NET will provide interrupt switching for four stereo audio paths. Each alert insertion can occur simultaneously on one or more station outputs, but alerts can not be overlapped.
