The XE300 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 XE300 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 XE300 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 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.

A comprehensive range of input options is available. The XE300 comes as standard with composite input and 3 SCA/RDS inputs. The XE300/S includes a stereo limiter and stereo encoder with additional AES/EBU input allowing stereo digital input and the XE300/RBRX includes a rebroadcast receiver for translator/rebroadcast applications.
