{"product_id":"matrix-audio-silver-copper-hi-fi-clock-cable","title":"Matrix Audio Silver Copper Hi-Fi Clock Cable","description":"\u003cp\u003eThe Matrix Audio Silver Copper Hi-Fi Clock Cable carries a 10 MHz reference signal from a master clock to the components that can lock to it. It is a 50 ohm coaxial cable with a silver-plated OFC center conductor, PTFE insulation, two layers of silver-plated copper shielding mesh, and a crimped BNC connector on each end. Matrix rates it to 12 GHz with 0.125 dB per meter of attenuation at 100 MHz. Two lengths, 0.5 m and 1 m, built for the SC-1 Reference Clock and the four Matrix components with a 10 MHz clock input.\u003c\/p\u003e\n\n\u003ch5\u003eKey Features of the Matrix Audio Silver Copper Hi-Fi Clock Cable\u003c\/h5\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSilver-plated OFC conductor:\u003c\/strong\u003e A 0.9 mm single-strand, high-purity OFC core with a silver-plated surface.

At that frequency current concentrates near the surface of the conductor, so Matrix plates the 0.9 mm OFC core with silver to cut surface conduction loss and keep the amplitude and shape of the clock waveform intact. PTFE insulation and two layers of silver-plated copper mesh keep outside interference off the line.

Matching the two is what lets the receiving component lock onto the clock steadily instead of chasing a degraded edge. The bandwidth rating of 12 GHz and attenuation of 0.125 dB per meter at 100 MHz leave a 10 MHz signal with enormous headroom. If you are adding this to a non-Matrix system, check that the clock input you are feeding is 50 ohm, not 75 ohm, before you order.\u003c\/p\u003e\n\n\u003ch5\u003eCrimped BNC Connectors and a Semi-Flexible Body\u003c\/h5\u003e\n\u003cp\u003eBoth ends are terminated with crimp-type BNC connectors. A solder joint varies a little from cable to cable; a crimp is a mechanical, repeatable termination, so the impedance stays consistent through the connector. The semi-flexible coaxial body is stiff enough to hold the route you give it and pliable enough to turn a corner between shelves, which is what you want when four clock lines leave the back of one SC-1.\u003c\/p\u003e\n\n\u003ch5\u003eWhich Matrix Audio Components Use This Cable\u003c\/h5\u003e\n\u003cp\u003eAny Matrix component with a 10 MHz BNC clock input, fed from the \u003ca href=\"\/products\/matrix-audio-sc-1-audio-grade-reference-clock\"\u003eSC-1 Audio Grade Reference Clock\u003c\/a\u003e and its four independently buffered outputs.
