Detailed Description

Oxygen Free Copper Conductors

The QED Performance Digital Audio cable uses 99.999% oxygen-free copper conductors. This material choice ensures minimal signal attenuation, maintaining the integrity of the audio signal over longer distances.

Optimized Coaxial Design

The cable features an optimized coaxial design with a true 75 Ohm ± 2% characteristic impedance. This precise construction helps achieve low jitter data transmission, crucial for high-fidelity audio reproduction. Low jitter ensures that the audio signal remains accurate and free from timing errors, which can degrade sound quality.

24k Gold Plated RCA Plugs

The RCA plugs on the Performance Digital Audio cable are precision-engineered and feature a six-leaf ground ring plated in 24k gold. This design provides a stable ground connection, which is essential for maintaining signal clarity and reducing interference. The plugs also include an integrated user grip, making them easy to handle and connect.

Enhanced Signal Protection

To further ensure the quality of the audio signal, the cable employs twin electrical screening. This dual-layer protection guards against electromagnetic interference (EMI) and radio frequency interference (RFI), which can introduce noise and degrade the audio performance.

Very Low Jitter

Jitter is a small, unwanted variation in the timing of digital signals, which can affect sound quality. The QED Performance Digital Audio cable has a very low jitter level, typically measured at just 50 picoseconds (ps). This ensures the audio signal is delivered with precision, resulting in clear and accurate sound without timing errors.
