NTP Delivers New Audio Routing System to RNE, Madrid 

The NTP 625 series is supported by a wide range of modules

NTP Technology has completed delivery of a router system with six NTP 625 frames to Spanish state broadcaster Radio Nacional de España (RNE) for installation at the network's Madrid headquarters.

"Radio Nacional de España has been using an NTP 625 routing system for the past six years and now has a total of 30 frames," comments NTP Technology Sales Manager Mikael Vest. "The six new NTP 625 router systems just delivered will serve as a backup to a 12-frame NTP 625 digital audio routing system which was delivered in February. The backup system is configured with redundant optical-fibre connections ensuring failsafe distribution of audio from the playout center in Master Control 2 to various transmitter interfaces elsewhere in the RNE building."

The NTP 625 series is supported by a wide range of modules including a sampling-rate converter, analogue I/O, AES/EBU I/O, microphone input, MADI interfaces, CPU/clock, QNX-based frame controller, optical interfaces and TDM interfaces. All I/O cards incorporate gain, filtering, summing, phase, delay, compressor/limiter, level detection and phase detection. VMC660 software controls the router system in terms of crosspoints, scheduling and signal surveillance.


NTP's 625 digital audio router is a modular system based on the 625-800 19 inch chassis which houses up to 18 plug-in modules configured as 5 RU high hot-swappable cards. Each chassis is scalable up to 2048 x 2048 crosspoints and can accommodate a redundant power supply and redundant frame controller.

Integrated into the state public broadcasting body RTVE (Radiotelevisión Española) in 1973, RNE is the Spanish state public radio service. The network consists of six channels including Radio Nacional, Radio Clásica, Radio Exterior de España and a 24-hour news channel. RNE's output is also available online.
