The XE 10 – 300W FM Exciter is a highly advanced, fully featured broadcast FM exciter that is also ideally suited for use as a low power stand alone transmitter.
Use of wideband design techniques means that frequency setting is easily achieved from soft keys on the front panel with no further tuning required. The frequency can also be remotely controlled via the RS232 or TCP/IP ports on the rear of the unit. The XE 10-300W FM EXCITER uses a unique ultra linear modulator to give superb sound reproduction with freedom from overshoots and artefacts. The modulator also features a precision TCXO for exceptional frequency stability. The PA Section in the XE 10-300W FM EXCITER uses the world renowned heat dissipating “fresh-air-tunnel” concept. The fan provides cooling to the specially designed heat sink with a stream of air that needs no filtering, saving on routine filter replacements. It 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 XE 10-300W FM EXCITER 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.
