Broadcast Tools MSRP-3 AES Three Station Digital EAS Relay

Broadcast Tools MSRP-3 AES Three Station Digital EAS Relay Overview
The Broadcast Tools MSRP-3 AES is a sophisticated three-station AES/EBU digital EAS relay/switcher, designed to enhance the performance of Emergency Alert Systems (EAS). It builds on the legacy of the original Multi-Station Relay Panel (MSRP), developed in 1996 for the Sage ENDEC, and is an ideal solution for modern radio stations and broadcast facilities. This advanced device provides reliable alert audio distribution and transparent audio interrupt switching for EAS encoders, supporting up to three stations and ensuring seamless communication during emergency alerts. The MSRP-3 AES is designed to work flawlessly with both analog and digital audio inputs, making it an invaluable tool for any broadcasting setup.

Reliable EAS Alert Insertion for Multiple Stations
The Broadcast Tools MSRP-3 AES is built to handle EAS alert insertion for up to three stations simultaneously, ensuring that critical emergency messages reach all necessary channels. The alerts can be inserted on one or multiple station outputs, making it perfect for large broadcast networks or radio groups. However, the system prevents overlapping of alerts, ensuring that each emergency broadcast is properly delivered without interference. This ability to control multiple stations independently provides broadcasters with a high level of flexibility and reliability when handling emergency communication.

Seamless Integration with Digital and Analog Inputs
One of the standout features of the MSRP-3 AES is its ability to handle both analog and digital inputs with ease. The encoder audio input can be switched between a balanced analog signal, which feeds into the built-in 24-bit analog-to-digital converter (ADC), or an AES digital input. The ADC offers sample rates of either 44.1kHz or 48kHz, and it can be configured via DIP switches or an external wordclock for precise synchronization. This flexible input switching ensures that the MSRP-3 AES integrates smoothly with any existing broadcast setup, whether you're using legacy analog equipment or state-of-the-art digital systems.

Advanced Control and Monitoring Capabilities
The MSRP-3 AES is equipped with multiple control and monitoring options to ensure seamless operation. The unit can be remotely controlled via an RS-232 serial port, TCP/UDP Ethernet commands, or contact closure inputs, giving you flexibility in how you manage the system. The front panel features recessed test switches for quick testing, and jumper-defeatable options allow for customization. Status relay outputs with LED indicators make it easy to monitor the unit’s operation, while a dedicated fourth AES output provides encoder audio for additional devices. This comprehensive control setup ensures that you can easily configure and monitor your system, ensuring uninterrupted service during emergency alerts.

Built for Reliability and Durability
Broadcast Tools has engineered the MSRP-3 AES to be fully RFI-proof, ensuring it performs reliably in challenging environments. The unit features sealed mechanical relays that provide transparent signal switching, using high-quality bifurcated-crossbar silver alloy contacts with gold overlay for maximum durability. These relays ensure that your system remains operational, even during the most demanding conditions. Additionally, the MSRP-3 AES is surge-protected and operates on a 12V DC power supply, making it a reliable choice for any broadcast or emergency alert system setup.
