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-Conductortm' technology that reduces signal to ground capacitance to vanishingly low levels.

Product Description

Details

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-Conductortm' technology that 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-ConductorTM 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.

JUST LISTEN

Silver plated conductors, LDPE dielectrics and legendary build quality combine to create audible sonic improvements. We urge you to compare Reference XLR 40 not only to your favourite cable but also alternative brands and models at any price!

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.

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 or high end streamers to DACs using digital XLR AES/EBU.

 

Ferrite Insulation Technology

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

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

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.
