Accusound/Mascot Instrument radio microphone system. This is a UHF true diversity headset system. True diversity means the receiver uses two active antennas, the internal detection circuitry automatically takes the signal from whichever antenna has the better signal. This prevents drop-outs when the user moves about. Multi-reflections within buildings often creates weak areas within the user area. By having two antennas, and two receiving circuits, even though they may seem close together, due to the wavelength of the transmitted signal they receive significantly different signals giving the system a more robust, interference free reception.The frequencies available within the unit are UK licence free frequencies meaning no need to purchase a licence .

The Instrument system uses the body transmitter which has a mute/power button for the user. The system may be used with any of the Accusound microphone systems. The body trasnmitter is the worn on a belt or in a pocket.
