QED REFERENCE Digital Audio 40

Reference Digital Audio 40 använder en noggrant konstruerad geometri för att uppnå den exakta karakteristiska impedansen som krävs för maximal överföring av S/PDIF-signaler. Silverpläterade ledare ger en väg med låg resistans för höga frekvenser och QED Digiloc2™-kontakter matchar kabelns karakteristiska impedans bättre, vilket minskar returförlusten med upp till 1,5 dB jämfört med konventionella RCA-kontakter. Detta säkerställer optimal signalöverföring och förbättrad mikrotiming av ljudsignalen

FEATURES AND BENEFITS

Just Listen

Silver plated signal carriers, effective high-quality shielding and impedance matched cordage and plugs all combine to create audible sonic improvements when compared to the competition

Triple Layer Electromagnetic Shielding

By implementing factory-controlled geometry and low permittivity foamed polyethylene dielectrics, Reference Digital Audio 40 maintains the correct characteristic impedance to match the transmission line between digital source and sink precisely. This makes for a very low jitter signal transfer which, listening tests have shown, leads to clearly audible sonic improvements.75 Ohm Impedance matched Digiloc2TM RCA plugs

Feature high-purity copper signal and ground connections supported by a new non-conductive low eddy current body. The hollow central pin eliminates the skin effect at high frequencies and the revised locking barrel design clamps the dual blade ground connection firmly to the RCA sockets for improved noise rejection. The optimised geometry of the plugs and the dielectric materials selected have resulted in a closer impedance match for low jitter S/PDIF transmission, resulting in a measurable 1.5 dB reduction in insertion loss, compared to ordinary RCA plugsThe all new Digiloc2™ design cleverly substitutes high rigidity thermoplastic material for both the inner support structure and the cable strain relief to eliminate the distorting effects of eddy currents, which are always present in ordinary plugs where bulk brass is used instead.
