The XR6 is purposely designed for demanding AM broadcast applications that require reserve power. This extra power overcomes antenna system losses such as those encountered in complex directional arrays. It allows aggressive audio processing and high levels of asymetrical modulation to produce more sideband energy and a louder signal. Extra power also makes it possible to maintain full power AM transmission while transmitting a digital signal or simultaneous phase-coded data.
The XR6's graphic user interface and soft-keys give you simple menu control of operating modes. Six power level selections are continuously adjustable over the full range using raise/lower commands. Programmable system profiles let you define schedules for changes to power and modulation settings. An LED diagnostic status flow diagram continually monitors the system and an advanced control, alarm and 128 event time stamped logging system allows service personnel to easily identify problems.
The XR6 has been specifically designed to support the digital transmission formats now available and being developed for use on existing AM channels. Nautels employs an ultra linear extended band filter that maintains an envelope bandwidth of 40kHz. The RF drive design optimises IPM to ensure minimal phase error. This provides superior spectral performance when transmitting a digitally encoded signal using digital modulation techniques such as HD Radio and DRM. The XR6 transmitters' digital performance is outstanding, even with the limited bandpass performace of real-world antenna systems. This combination of compatibility, performance and flexibility makes the XR6 an excellent choice for digital broadcasters.
