Now Any Speakers Can Be Cable-Free

Why aren’t wireless speakers commonplace? The problem is ensuring a reliable signal that’s free from interference in homes full of potentially conflicting devices. The risk of signal interference exists because the only broadcast space available for wireless systems is the 2.4GHz frequency, the same one used by Wi-Fi routers, Bluetooth devices, digital cordless phones and even microwave ovens. Because it’s such a widely used frequency, it has been difficult to create wireless speaker systems that can operate free from signal interference.

KEF has developed a remarkable solution that combines signal transmission, reception and processing technologies that at last makes high-performing wireless speakers a reality: the KEF Wireless System. Superb signal reliability is delivered with CD-quality sound that is a match for even the most demanding audio systems. Set-up is simple and you can locate your speakers almost anywhere in the room. The KEF Wireless System is compatible with the full range of KEF speakers, but can also be used with most other speaker brands. If the problem of hiding lengthy cables has restricted where you put your loudspeakers, now you’re free.

Place your speakers virutally anywhere in the room

Surround Sound--Minus the Cables

Revolutionary Technology

In order to achieve full-bodied sound reproduction, KEF developed a leading edge 2.4GHz wireless transmission technology that uses the most advanced error protection and sophisticated 'intelligent' adaptive frequency hopping to ensure an interference-free signal. Transmission is not affected by devices like microwave ovens, mobile phones, digital cordless telephones or wireless LAN routers, but you still get the superior sound quality demanded by true audiophiles with no mutes, dropout or loss of bonding.

The narrow signal band used is sufficient for high-quality audio transmission, yet perfect for finding a path through the congested environment of a home filled with potentially conflicting devices. This narrow band is a feature of High Fidelity Adaptive Differential Pulse Code Modulation (HFADPCM), and along with advanced error correction technology, ensures an exceptionally robust delivery of CD-quality audio between the transmitter and receivers.

Advanced technology creates CD-quality sound--wirelessly

The KEF Wireless System detects other transmitters in the 2.4GHz frequency, such as cordless phones, Wi-Fi routers and microwave ovens and ‘hops’ out of the way of potentially conflicting signals. With this Advanced Adaptive Frequency Hopping Spread Spectrum (AAFHSS) technology, a processor constantly monitors several channels at a time and continually switches to the strongest available to ensure a constantly pure signal. It’s all done in milliseconds, so you don’t even notice it. Nothing gets in the way of your enjoyment of pure, clean audio.

Free yourself from speaker wires

Use Your Existing Speakers Wirelessly

The KEF Wireless System is an ideal add-on for any existing rear surround sound speaker set-up--regardless of the brand--and can also be used for stereo speakers in a hi-fi system where hiding cables is an inconvenience, especially when the amplifier is some distance from the speakers. You can enjoy the convenience of a cable-free solution with no loss of signal and the sound quality you expect from KEF.

Set-Up is a Snap

It is, of course, essential that even the most high-performing technology is free from complicated set-up and operating procedures. So KEF has made sure you’ll be up and running in minutes thanks to simple connections and power delivery to the transmitter and receiver units through discreet adaptors. Just connect a receiver to each speaker and partner the transmitter with your amplifier to make wires across your floor a thing of the past.

Once in use, you can forget about the technology because automated signal processing means there are no buttons or dials to get in the way of enjoying great sound.

Locate Speakers Anywhere

You can locate your speakers virtually anywhere you want to in the room while still receiving remarkable sound with exceptional clarity and noteworthy lack of extraneous interference. You can even move your speakers around whenever you want, such as hiding them safely away during parties, because you don’t have to maintain a line of sight between transmitter and speakers.
