General description
Combining the very latest technologies with our proven RF experience, our 20 W and 100 W exciters have
been designed to offer an innovative and highly reliable solution.
Among the first FM transmitters based on 6
th
Generation MOSFET, these transmitters are not only more
robust, they also deliver efficiency of up to 74%. Top signal quality and performance are achieved thanks to
the “FM Band Direct to Frequency” digital modulator which is at the heart of this range.
The manufacturing quality and the simplicity of use make these truly powerful transmitters to broadcast
analog FM programs.
The Helios FM 20/100 W is fully protected against overheating, VSWR and lightning.
In addition, several innovative features are available, such as RDS encoding and automated audio backup.
Fully featured for local maintenance and configuration, it also allows full remote control by Web server,
SNMP, RS232 or GPIOs*.
* Options available with the current version are:
•
Basic RDS: the internal RDS encoder makes it possible to manage basic RDS parameters (PI, PS,
TP, TA, PTY, MS, DI, radiotext, PTYN, group sequence, AF, 1 PSN, 2 DSN, dynamic scrolling PS)
•
GPIO: this additional board allows remote control and management of your transmitter.
•
TCP/IP: this additional board allows remote configuration via a web site and SNMP management
Project co-financed by the European Union, involved in the Aquitaine Area,
through the European Funds for local development.
