KEF Universal Wireless System

The KEF Universal Wireless System consists of three pieces of equipment, a transmitter which is normally positioned near your TV, and two receiver amplifier modules which each connect to the left and right rear channel speakers in a surround sound speaker package - all that is needed at the rear of your room is a mains power supply.

Using the 2.4GHz wireless platform technology, the wireless connection is impervious to interference contamination from other wireless devices, ensuring that the audio quality is always pristine.

A range of upto 70ft is possible between the transmitter and receivers.

KEF Universal Wireless System is a uniquely stable device which delivers high quality wireless audio transmission without the need for unsightly speaker cables.

CD quality audio transmission achieved with a revolutionary 2.4GHz radio frequency HFADPCM (Hi-Fidelity Adaptive Differential Pulse Code Modulation) wireless link that ensures real time audio delivery with no mutes, audio dropouts or loss of bonding.

Wireless receivers can be used with any speaker of the user's choice.

AAFHSS (Advanced Frequency Hopping Spread Spectrum) with advanced forward error correction is utilised to ensure that the audio signal remains interference-free from devices such as wireless LAN routers, digital cordless telephones, mobile phones and microwave ovens.

Unique Pre-emptive frequency hopping and adaptive channel diversity features enable the transmission system to change channels automatically to a pre negotiated frequency so that the system hops to the best available channel before errors start to occur.
