Spanish public radio broadcaster RNE (Radio Nacional de Espana) is upgrading the audio routing systems at its regional studios, following the recent installation of an 11-frame router at its headquarters in Madrid, writes Kevin Hilton.
RNE has ordered 15 NTP 625 digital routers though Lexon Broadcast, with delivery due to begin during December. Three-frame systems will be used at the larger broadcast centres, while single-frame routers have been specified for smaller areas of the network.
The new routers will be controlled by a NTP 635-600 control system with a version 3.0 QNX-based core. This is the same as the set-up in Madrid and gives main and back-up database support and TCP/IP control. Also part of the installation is the 715 multiplex console, which is used extensively by RNE. Every single-frame router has 32 analogue transformer-coupled input and output channels, with 32 AES/EBU channels with a 512×512 matrix.
RNE is part of RTVE (Radiotelevision Espanola) and operates a network of six channels: Radio Nacional (predominantly speech programming), Radio Clásica (concerts and classical music), Radio 3 (pop, rock and folk music), Ràdio 4 (regional broadcasting in Catalan), Radio 5 Todo Noticias (24-hour news) and international service Radio Exterior de España.
