Module 8x IP to FM GT 22 C

Module 8x IP to FM
GT 22 C
Product information
The GT 22 C module is part of the Tangram product
portfolio. The GT 22 C module allows you up to 8
services in FM format to your network.
Tangram is a very high density and highly flexible
solution for all kinds of networks. The WISI Tangram
chassis uses a fully redundant concept (n+1, 1+1).
Features:
• Gigabit Ethernet MPEG-TS to analogue FM Decoder
• Up to 8 FM channels on 1 RF output
• Total of max. 48 FM channels in 1RU
• Outstanding signal parameters by direct digital modulation
• Digital FM modulation & RDS insertion • User friendly configuration via standard web browser
• Low power consumption
