The QED Reference XLR 40 builds on the multi-award winning Audio 40 range of products, now available in Digital AES/EBU form.
XLR 40 is designed primarily for low jitter as this has been identified by QED as a major factor which leads to a high fidelity experience. Further steps have been taken to eliminate minute timing errors in the cable by the use of a special floating Zn/Mn ferrite jacket alongside use of QEDs unique 'Tri-Conductor(TM)' technology reduces signal to ground capacitance to vanishingly low levels.
Award Winning Heritage
Reference XLR 40 builds on the multi-award winning Audio 40 range of products, now available in XLR form. QED have joined forces with world renowned professional audio connector supplier Neutrik (UK) to bring you an innovative new XLR balanced interconnect cable with legendary build quality and reliability.
Professional Standard Neutrik plugs
Neutrik XX-14 Nickel Series XLR gold plated connectors are provided as standard with Reference XLR 40 cables. These connectors are rugged and reliable and are the connector of choice for audio professionals around the world. They are particularly suited to QED's Tri-Conductor(TM) geometry due to the additional ground spring contacts which make for better shell ground continuity for the unique electrostatic screen which is only connected at the source end of the cable.
Silver plated conductors, LDPE dielectrics and legendary build quality combine to create audible sonic improvements. We urge you to compare it not only to your favourite cable but also alternative brands and models at any price!
Unique Tri-conductor Technology
QEDs unique Tri-Conductor technology uses a third Silver plated 99.999% OFC conductor which is integrally twisted alongside the similarly constructed signal pair to carry the ground return currents. This reduces signal to ground capacitance to vanishingly low levels affording the cable improved common mode rejection of mains hum pickup over ordinary "hot cold and screen" cables. This geometry is particularly effective in pro hi-fi audio applications when connecting pre and power amps using balanced cables.
Floating ferrite jacket
Absorbs high frequency noise signal components outside the audio band. When measured using high frequency measurement equipment, Audio 40 products convey a comparably cleaner and tighter signal pattern when its special Zn/Mn ferrite jacket is present. This has a beneficial effect on audio signal micro-timing, reducing digital jitter and timing errors to an ultra low level.
Ferrite Insulation Technology
A special floating Zn/Mn Ferrite jacket is used within the Audio 40 cordage to absorb very high frequency noise components outside of the audible band that have an adverse effect on the micro-timing of the audio signal.
Tri Conductor Technology
QEDs unique Tri-Conductor technology uses a third Silver plated 99.999% OFC conductor which is integrally twisted alongside the similarly constructed signal pair to carry the ground return currents.
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.
