QED Reference Digital Audio 40 Lead

QED’s Reference Digital Audio 40 Lead-Establish is a very good digital audio cable that improves sound quality. It is designed to connect audio systems. Such as CD players, DACS, Blu-ray players, and amplifiers and receivers. Usually, the best audio products are in the latter group.

The QED Reference Digital Audio 40 Lead uses a carefully engineered geometry to achieve the precise characteristic impedance required for the maximum transfer of S/PDIF signals.

Silver-plated conductors deliver a low-resistance path for high frequencies, and the QED Digiloc2 plugs more closely match the cable’s characteristic impedance. Reducing return loss by up to 1.5 db compared to conventional RCA plugs. This ensures optimal signal transfer and improves audio signal micro-timing.

Delivery of Superior Digital Audio Signals

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

Triple Layer Electromagnetic Shielding

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

Impedance-matched Digiloc2 RCA plugs

It features a 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. The revised locking barrel design clamps the dual-blade ground connection firmly to the RCA sockets for improved noise rejection.

The plugs’ optimal geometry and the selected dielectric materials 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 plugs.

The all-new Digiloc2 design substitutes high-rigidity thermoplastic material for the inner support structure and the Reference Digital 40 cable strain relief to eliminate the distorting effects of eddy currents. Which are always present in ordinary plugs where bulk brass is used instead.

Triple Layer Electromagnetic Shielding

A dual-layer, closely woven 99.999% OFC shield braid and aluminium mylar wrap with 100% coverage comprise a triple-layer electromagnetic shield coaxially spaced around the central signal carrier within a foamed polyethene dielectric.

This ensures that interference signals induced by nearby high-current noise sources do not contribute to higher signal jitter than would otherwise be the case. By the same token. The shielding prevents unwanted voltage-induced interference from escaping the cable. Which might affect nearby analogue signal carriers.

Sound Quality Actuation

QED Reference Digital Audio 40 Lead has several practical and innovative features. Which, together, increase efficiency and improve audio detail. Lessening the resistance to an actual 75-ohm level has become a crucial step in that direction. Through which digital audio communication gets the best, most faithful, and cleanest sound.

Sophisticated Cable Type

The quality components and absolute precision used to create this digital audio cable make it a very reliable and high-quality product. It employs an excellent silver-plated conductor and a superb dual-layer shielding system to isolate the digital signal from the outside world.

Bendable and Trustworthy

On the one hand, this cable is user-friendly, as its design is user-driven. Focusing on the most beneficial aspects of use. In addition, the cable has an ergonomic design that can be routed through tight and twisted situations and makes the regular working of the audio system trouble-free.

The cable is designed to last and features the latest connectors. That gives it a more secure and resistant connection, making it harder to break.

Characteristics and Advantages

• Guarantee of High-Resolution Audio Support: This ensures the cable’s capability of transmitting high-definition audio formats, even without any signal loss.
• Real 75 Ohm Impedance: The decrease in signal timing errors caused by the low level of proper impedance creates a more transparent sound. And a perfect synchronisation process.
• Dual-Layer Shielding: Minimises the influence of external factors on the sound by giving the cleanest possible signal.
• Silver-Plated Conductors: Lower the resistance of the transmission pathway. Therefore, the signal transmission will be superior.
