QED Performance Digital Audio Cable 3M

Digital Isn't Immune to Physics.   Digital audio is often treated as simple. After all, the signal is just ones and zeros, right?   Not quite.   Moving digital audio from a source to a DAC requires timing, precision and protection from interference. When those things aren't taken seriously, the result can be increased jitter, signal degradation and a system that's not performing at its best.   Performance Digital Audio is designed to take care of that connection.   Using a true 75Ω cable geometry, low-loss dielectric materials and enhanced dual-layer screening, it's engineered to transfer digital audio accurately and reliably between source and DAC. The kind of thoughtful engineering that's built QED's reputation over more than five decades.   Whether you're connecting a streamer, CD transport or digital music source, Performance Digital Audio gives you the confidence that you've got this connection right. Digital Done Properly. A digital audio cable has one job: transfer data accurately from source to DAC. The challenge is doing that while maintaining correct impedance, minimising signal loss and protecting the signal from external interference. That's exactly what Performance Digital Audio is designed to do. True 75Ω Design Unlike generic audio cables, Performance Digital Audio is engineered with a true 75Ω characteristic impedance, matching the requirements of S/PDIF digital audio transmission. Why does that matter? Because impedance mismatches can create signal reflections that contribute to timing errors, or jitter. By maintaining the correct impedance throughout the cable, Performance Digital Audio helps preserve signal integrity from source to DAC. Built to Keep Jitter Under Control At the heart of the cable is a solid-core 99.999% oxygen-free copper conductor surrounded by a low-loss foamed polyethylene dielectric. Together, these materials help minimise insertion loss and support accurate signal transfer, reducing the potential for cable-induced jitter. We're not interested in digital magic. Just good engineering. Protected From Interference Modern homes are noisy places electrically. Wi-Fi routers, televisions, games consoles, power supplies and smart devices all generate interference that can affect nearby cables. Performance Digital Audio uses dual-layer shielding with a close-weave shield braid and aluminium/mylar foil wrap to provide 100% electromagnetic coverage, helping keep unwanted interference out of the signal path. Flexible And Easy To Install An ultra-flexible TPE outer jacket makes Performance Digital Audio easy to route behind equipment while providing effective protection from day-to-day mechanical stress. Gold-plated connectors ensure a reliable, long-lasting connection.
