The new Silver Sonic D-750 is an ultra-low loss digital coaxial cable that has been engineered to deliver precision 75 ohm signal transmission. It replaces the popular D-75 and improves upon that cable’s well-regarded ability to accurately transmit today’s complex and sensitive digital signals. The most common use for this cable is to connect the digital output of a CD or DVD transport to an outboard Digital to Analog converter or other processor. Several features built into this product make it superior for digital audio use.
A solid, silver-coated center conductor is used to maintain the most uniform impedance. A solid conductor minimizes signal reflections, a characteristic that is crucial to accurate digital data transmission. This center conductor is encased in DH Labs’ proprietary Air-PTFE Matrix dielectric, featuring an astonishingly low dielectric constant of 1.4. This material yields the lowest loss and most uniform attenuation versus frequency curve of any dielectric material.
Noise rejection is maximized by a 2 Layer shield. This provides 100% coverage for complete noise immunity. The combination of an aluminum Mylar shield and a heavy braid keeps ground resistance as low as possible. The braid is precision wound with carefully controlled tension to minimize a phenomenon called “VSWR spikes”, more commonly referred to as jitter.
The result of these efforts is a cable that delivers precise signal transmission with optimal balance and superior dynamics to well beyond 2 Gigahertz. The D-750 is available in bulk, or skillfully hand-terminated with our matching coaxial RCA-750 connector. For maximum performance, 75 ohm BNC connectors are also available.
Continuing with the DH Labs tradition of providing maximum value, the D-750 costs much less than its superior performance level would suggest.
