S8601 1kW FM Transmitter

The S8601 FM transmitter is an evolution of the highly modular architecture for which Eddystone Broadcast transmitters are legendary. The use of 600/700W hot-pluggable Power Amplifier modules means that removal of amplifiers can be carried out with minimal reduction in output power. The design features hot-pluggable switched mode 2kW power supplies. A single power supply is sufficient to operate the S8601 transmitter but additional power supplies can be fitted to provide redundancy.

  • Compact Amplifier and PSU Modules are replaceable on air
  • Highly efficient LDMOS amplifiers
  • Fully compliant with ETS 300 384 specification for FM transmitters
  • Easily configured into a wide range of system architectures
  • SMPS power supplies with PF correction and efficiency approaching 97%
  • Comprehensive remote monitoring facilities· Touchscreen LCD displays ensures easy local monitoring
  • Automatic changeover accommodates dual exciters
  • Fully redundant Amp & PSU modules common across the range
  • Monitoring & Control

    The S8601 transmitter includes SNMP for remote control and monitoring, which is supported by a built-in webserver. The modules provide Wi-Fi connectivity for local monitoring and control, but can also be connected using LAN via an Ethernet cable. The system is programmable to provide alarms/alerts via email, as well as the option to have alarms/alerts through SMS. The system can include external sensors, to monitor information such as voltage usage, output power, temperature and humidity.

    The systems offer local monitoring by way of the on-board touchscreen LCD’s which show the information on the amplifiers and overall system accordingly.
