Overview: This AudioQuest Columbia product contains two 1-meter audio interconnect cables with male RCA connectors on each end. Each cable is equipped with a 48-volt DBS pack which aligns the molecules in the dielectric, and enhances performance. They are for connecting high-end audio sources to your amplifier or receiver.
Triple-Balanced Design: The Columbia audio interconnect cables are Triple-Balanced, with three identical insulated conductors. The shield is never used as an inferior conductor. Two conductors are used together for the much higher potential across the negative connection, providing a substantial performance advantage. The shield is only attached at one end, providing total shield coverage without compromising the negative conducting path.
Solid Conductors: Columbia interconnects use two 21-gauge and one 20-gauge solid conductors instead of stranded conductors. Electrical and magnetic interaction between strands in conventional cables are the greatest source of distortion, often causing a somewhat dirty harsh sound. Solid conductors produce less distortion, thus produce a very clean sound.
Metal: Perfect-Surface Copper+ (PSC+) has a very smooth and pure surface. AudioQuest's proprietary metal processing technology protects the wire's surface at every stage of drawing and fabrication. An ultra pure copper is kept soft, pure, and smooth as possible during the manufacturing process, resulting in a very low distortion PSC+ conductor. The resulting sound is more focused.
Insulation: All of Columbia's conductors are insulated using Polyethylene Air Tubes. Air absorbs virtually no energy (which could be stored and released as distortion), and Polyethylene is a low-loss material that causes very little interference or distortion. The conductors and drainwire are wrapped in a PVC jacket with a black, green and gray nylon braid on the outside.
Dielectric-Bias System (DBS): Each Columbia audio cable has an attached 48-volt Dielectric Bias System (DBS) pack to enhance performance. All insulation slows down the signal on the conductor inside, and when the insulation is unbiased, it slows down parts of the signal differently. This creates problems with time-sensitive, multi-octave audio. The DBS creates a strong, stable electrostatic field which saturates and polarizes the molecules of the insulation. This minimizes energy storage in the insulation and the multiple non-linear time-delays. The audio has more detail and dynamic contrast. A test button and LED allow you to occasionally verify battery performance.
Noise-Dissipation System: This cable uses a metal and carbon-loaded synthetic shield with 100% coverage to capture RF interference that could modulate the equipment's ground reference. The RF is dissipated through a 22-gauge solid, silver-plated copper drainwire.
RCA Plugs/Cold-Weld System: The novel plug design enables a perfect heat-free connection between the cable and the plug.
Directionality: The cables are directional, and should be connected in the direction of the signal flow (i.e. from the CD player to the amplifier). The RCA plugs are marked with arrows on each end to indicate the intended signal direction. When connected in the proper direction, the music becomes more relaxed, pleasant, and accurate. The DBS pack is attached near the audio source end of the cable.
