XE75 – 75W Exciter

The XE75 Exciter is an advanced, fully featured broadcast FM exciter that is also ideally suited for use as a low power stand alone transmitter.

The XE75 will operate into any load without damage thanks to its VSWR cut back circuit that protects the power amplifier stage from adverse operating conditions. The XE75 front panel LCD metering shows forward and reflected power together with internal voltages, temperature and the modulation level. Quick view LED’s show advanced status information including CPU ok, system normal, modulation status and external mute. The PA section also has LED’s which show forward, reverse, temperature and CPU status. The addition of the unique modulation alarm, gives broadcasters alarm status outputs and indications that will show loss of audio or over modulation. A front panel monitor point for RF output is provided, as is a fully buffered baseband monitor for accurate monitoring of the modulator input. The rear panel includes a remote control/monitoring socket that allows carrier muting and status signalling to an external system, additionally data sockets are provided for use with systems that have the ability to control exciters via RS232 or TCP/IP. The XE75 is fully compatible with N+1 systems, with remote frequency selection being achieved by either RS232/TCPIP interface or rear panel logic selection of up to 6 preset frequencies. Very conservatively rated components and a switch mode power supply are used to ensure extremely high reliability and to give good efficiency. A comprehensive range of input options is available.
