The AudioQuest Mackenzie RCA-to-RCA analog audio connection cable has a length of 1.5 meters and features a brown outer jacket. This cable is designed for connecting audio devices to amplifiers and receivers and uses solid Perfect-Surface Copper+ (PSC+) conductors that minimize distortion by reducing grain boundary effects and maximizing linear high-frequency noise shielding. The conductors are directionally controlled to optimize signal integrity by diverting noise from critical connection points, with arrows on the connectors indicating the correct orientation. The insulation is made from foamed polyethylene material, which preserves dynamic contrasts in audio signals. A carbon-based network noise shielding system employs alternating layers of metal and carbon-containing plastics to absorb and reflect high-frequency interference before it reaches the ground connections, thus preventing modulation of device ground references. This three-layer noise shielding approach effectively shields high-frequency noise better than traditional shielding methods. The cable construction focuses on maintaining signal purity through controlled impedance characteristics and minimized conductor interactions in solid conductors. Designed for adult users in professional and home audio systems, this connection delivers reliable performance for high-fidelity audio systems where clean signal transmission is essential. The AudioQuest Mackenzie model represents a balanced approach in audio cable technology, combining technical innovations with practical connection solutions for analog audio applications.
