  • Digital Signal Processing: Measures, filters and compresses standard analogue audio signals and converts them into digital format. Allows advanced RF and audio processing techniques to be applied to maximise the radios performance.
  • Advanced Signal Management: Suppresses unwanted signals on adjacent channels and matches the receiver frequency to the incoming signal. This unique GME feature is critical to optimise performance of 80 channel radios.
  • Dynamic Volume Control: Automatically compensates for variations in received audio level, this feature provides a constant audio output level greatly enhancing the quality of the reception and simplicity of use.
  • Unique Display Flip Function: Unit can be mounted with the speaker facing upwards or downwards and the display flipped over using a simple key-press sequence to allow viewing of the display from either mounting orientation.
