AST2000 - Coloet

2000 W AST 2000

The COLOET AST FM MULTIAMPLIFIER line is a state-of-the-art heavy-duty FM high efficiency technology.
It is a broadband agile 88-108 MHz, modular design transmitter with an output power from 2.0 KW to over 10 KW.
It basically includes an MPX input and remote control via SNMP and WEB pages and TLC/TLS, but can be equipped with StereoCoder – Fully Dynamic RDS – AES/EBU optionsThe AST FM transmitter line is designed to fulfill the requests of those remote stations in need of a heavy-duty, cost-effective transmitter design.
