SPEAKER CABLES:

A quantity of 2 means you will receive a pair of speaker cables e.g. for your front left and front right speakers. By entering a quantity of 1, you will get a cable for a single speaker e.g. centre speaker and this option also enables you to vary the length (and termination) of your cable for each speaker.

OTHER CABLES:

A quantity of 1 means you will receive a single cable in the case of aerial, satellite, subwoofer, digital coaxial & optical cables and a pair of cables in the case of 2 rca to 2 rca analogue audio cables.

NON-CABLE PRODUCTS:

A quantity of 1 means you will receive 1 of the specified products.

What QED say

 

QED's superior toslink optical digital audio interconnect cable made with real glass Reference Optical Quartz is the first of its kind, consisting of 210 separate boro-silicate glass fibres.

The cable allows you to experience stunning sound when connecting DACs, TV’s, CD players and Blu-Ray players to amplifiers or receivers because it has a much higher bandwidth and only 1/10th of the attenuation of traditional acrylic fibres. Reference Optical Quartz vastly exceeds the demands for high definition multi-channel digital audio with a bandwidth of over 150MHz which is totally unaffected by bending the cable.

 

QED PMMA Optical Fibres QED Reference Optical Fibres

PMMA Optical Fibres

A typical optical fibre is made of an acrylic glass material known as PMMA (Polymethyl-methacrylate). This acrylic core allows the light to take many different length paths through it. Timing differences are introduced – accounting for typically up to 145ps of Jitter.

Signal losses also occur when light is incident above the Critical Angle and is not reflected back (Yellow).

Reference Optical Quartz

Reference Optical Quartz has in excess of 210 Glasscore™ fibres each thinner than a human hair. This ensures ultra low jitter because the smaller numerical aperture reduces the range of angles of acceptance leading to straighter signal paths.

 

Glasscore Technology

 

QED's new Glasscore™ technology employs multiple fibre bundles of ultra-fine boro-silicate glass optical fibres (GOF) of no more than 50um each to make up the 1mm diameter necessary to conform to the Toslink standard connectors. Because the fibres are so small the different paths taken by the light rays are similar in length virtually eliminating the timing error and introducing less distortion and jitter. This has the effect of increasing bandwidth and the accuracy of the data transmission.

 

Stepped Refractive Index

 

The quartz fibres are coated with a cladding of low Refractive Index to guide the light signal.

 

Over 150MHz Bandwidth

 

This vastly exceeds the demands for high definition multi-channel HD digital audio. In contrast to conventional acrylic glass optical cables quartz glass cables can deliver signals up to and including 24bit/192kHz with very low jitter . Reference Optical Quartz can provide a much higher bandwidth than a single acrylic glass fibre with 1/10th of the attenuation.

 

Ultra Low Jitter/ Ultra Low Loss

 

QED have calculated that jitter (distortions caused by timing differences between the different light paths) in conventional optical cables could typically reach up to 145ps. In Reference Optical Quartz, timing errors are virtually eliminated, introducing less distortion, jitter and ultra low loss < 0.03 dB/m.

 

QED Glasscore Technology

Glasscore™ Technology

Instead of using traditional low performance polymethyl methacrylate (PMMA) plastic optical fibres (POF) which come as a single 1mm OD fibre the cable incorporates 210+ boro-silcate glass optical fibres (GOF) which give improved jitter performance and higher bandwidth capability.
QED Ultra Low Jitter

Ultra Low Jitter

Jitter is the undesired deviation from true periodicity of an assumed periodic signal in electronics and telecommunications, often in relation to a reference clock source. A cable displaying ultra low jitter has been measured at
typically 30ps.

About QED Cables Made in United Kingdom

QED is an award winning British company with over 40 years of experience in the audio-visual connectivity industry.

In 1973 Bob Abraham and Ian Vine founded QED Audio Products and changed the way people think about hi-fi cables. By the time QED 79 strand speaker cable was launched in 1978, it wasn’t looked upon as ‘just another speaker cable’ but was instead regarded as a serious hi-fi component, making a fundamental change in the way people thought about cables.

QED's reputation for innovation and technical excellence is known throughout the world. The latest computer-aided design techniques allow their research and development team to keep pace with technological advances and deliver products that achieve the highest levels of performance and reliability. This is why QED products are recommended by so many of the world’s leading hi-fi and home theatre equipment manufacturers.

QED offer a range of connectivity products spanning from both consumer and installation cables, wireless products and switching devices to satisfy every audio visual need.

QED is Europe's number one award winning connectivity brand and has won more prestigious cable awards from ‘What Hi-Fi? Sound & Vision’ magazine than any other brand (Awards 1981–2013).
