Audioquest Tower 3m 3.5mm-RCA ---- 4200 dinara Solid long-grain copper (LGC) conductors Foamed-polyethylene insulation Metal-layer noise-dissipation system (NDS) Asymmetrical double-balanced geometry Cold-welded gold-plated rca plugs Analog-Audio Interconnect Cable named after the Tower Bridge in London that was completed in 1894. In all Bridges & Falls, you'll find better metals and more sophisticated technologies including Air-Tube insulation, Dielectric-Bias System, and Noise-Dissipation System at lower prices than ever before. Note: All cables in our Bridges & Falls Series place their left and right channels in a single jacket, and feature our Asymmetrical Double-Balanced geometry with separate high-quality positive and negative conductors. This design allows for a thin, flexible, and uniquely versatile high-performance cable that can be terminated with a variety of today¡ ¯ s connections, including 3.5mm (male or female), DIN, and RCA. Do keep in mind, however, that, by necessity, the plugs on Bridges & Falls cables are fairly close together. If the L and R inputs of your components are more than 3¡ å (7.6cm) apart, please consider models from our Rivers or Elements Series. ASYMMETRICAL DOUBLE-BALANCED GEOMETRY Purpose designed for single-ended applications, Asymmetrical Double-Balanced Geometry offers a relatively lower impedance on the ground for a richer, and more dynamic experience. While many single-ended cable designs use a single path for both the ground and the shield, Double-Balanced designs separate the two for cleaner, quieter performance. SOLID LONG-GRAIN COPPER (LGC) CONDUCTORS Solid Long-Grain Copper (LGC) allows a smoother and clearer sound than cables using regular OFHC (Oxygen-Free High-Conductivity) copper. Solid conductors prevent strand interaction, a major source of distortion. The surface quality is critical because a conductor can be considered as a rail-guide for both the electric fields within a conductor, and for the magnetic fields outside the conductor. LGC has fewer oxides within the conducting material, less impurities, less grain boundaries, and definitively better performance. METAL-LAYER NOISE-DISSIPATION SYSTEM It's easy to accomplish 100% shield coverage. Preventing captured Radio Frequency Interference (RFI) from modulating the equipment's ground reference requires AQ's Noise-Dissipation System (NDS). Traditional shield systems typically absorb and then drain noise/RF energy to component ground, modulating and distorting the critical "reference" ground plane, which in turn causes a distortion of the signal. NDS "shields the shield, " absorbing and reflecting most of this noise/RF energy before it reaches the layer attached to ground. FOAMED-POLYETHYLENE INSULATION Any solid material adjacent to a conductor is actually part of an imperfect circuit. Wire insulation and circuit board materials all absorb energy. Some of this energy is stored and then released as distortion. Because air absorbs next to no energy and Polyethylene is low-loss and has a benign distortion profile, Foamed-PE, with its high air content, causes much less of the out-of-focus effect common to other materials. COLD-WELDED, GOLD-PLATED TERMINATIONS This plug design allows for a connection devoid of solder, which is a common source of distortion. Instead of solder, the process employs a high-pressure technique. Because the ground shells are stamped instead of machined, the metal used can be chosen for low distortion instead of machinability.
