The D-75 is a thoroughly engineered, precision 75 ohm coaxial digital cable designed for accurate handling of digital audio 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 digital processor. Several features of this cable make it superior for digital audio use.A solid, silver-coated center conductoris used to maintain the most uniform impedance. The use of a solid center conductor minimizes signal reflections, which are very important in digital data cables. This center conductor is encased in a very uniform closed cell foam Teflon dielectric, which has an extremely low dielectric constant of under 1.4. This provides the lowest dielectric absorption and loss, along with the most uniform attenuation vs frequency curve.Noise rejection is maximized by a 2 Layer shield. This dual shield provides 100% coverage for complete immunity to noise. The combination of a 100% aluminum Mylar shield and a heavy braid keeps ground resistance as low as possible. The braid is wound with carefully controlled tension in order to minimize a phenomenon called "VSWR spikes" (a common cause of signal reflections in high frequency cables).The result of these efforts is a cable that can provide excellent performance to beyond 2 Gigahertz. The D-75 is available in bulk, or carefully terminated with our coaxial RCA connector, for minimum reflection and optimum signal transfer. For maximum performance, 75 ohm BNC connectors are available as an option.In continuing with our policy of providing maximum value, the D-75 costs much less than its performance level would suggest.The D-75 is available in factory terminated lengths, and also in bulk (unterminated) form.
