Wireless RF transmission technology

With this headphone system you can move around freely in the home or outside in the garden without the constrictions of a headphone cable! The RS 4 will transmit the stereo sound signal from your hi-fi system or any other sound source to the headphone receiver.

The Sennheiser system operates on a carrier frequency of approx. 434 MHz (RS 4) or approx. 926 MHz (RS 4-9), respectively. This frequency band has been licensed by the respective telecommunications authorities for “non-commercial use”, and apart from wireless sound transmission, it is also used for remote controls etc. (Please note: because of this, occasional interference may be experienced from e.g. car alarm radio keys.)

The maximum distance between transmitter and receiver should not exceed 100 m. Walls and ceilings are (almost) no obstacle, since radio waves travel through them. Transmission will remain clear and intelligible, and it is not necessary that transmitter and headphone receiver are in a direct line of sight. The only obstacle for radio waves are metal parts as e.g. in concrete constructions or wall coverings. They reflect radio waves.

If several wireless RS 4 headphone systems are operated simultaneously and are very close to one another (e.g. on the next floor, at a neighbour´s, or on the other side of the street) you have to agree on using different channels. For this purpose, the RS 4 system features three transmission channels, so everybody can transmit the music they want to listen to.
