Digital Alert Systems R198 - Manual (Page 4)

4
The Monroe Electronics Model R198 is a network controlled multichannel Analog to Digital
convertor and AES program switching system, used to insert EAS alerts into Broadcast Audio
Streams.
The unit features an unbalanced analog mono audio master input or unbalanced stereo master
input, and 4 independent AES program in’s and out’s. Each output can be seamlessly
switched from its incoming AES stream to the Master input (converted to AES) via network
control from the DASDECII EAS Controller.
A master GPI switch will switch all four channels at once, or individual switches are available at
each channel connector for control.
The individual AES channels feature a fail-safe bypass to maintain signal integrity in the event
of a power failure and can be configured for either 44.1KHz or 48 KHz data rates.
The network interface follows the standard Monroe R190A/R197 protocol for 10/100 base T
Ethernet interfacing to a DASDEC.
