Tributaries 4A is a high performance analog audio cable made by hand in Orlando, Florida. The 4A is engineered with a pair of balanced precision twisted wires. The conductors are solid HC-OFC 22AWG copper wires that are insulated with LDPE for better sound and flexibility. The audio pair is constructed in one overall jacket. The 4A is terminated with RCA connectors. The wires are hand soldered with high-quality lead-free solder in Orlando, Florida to solid gold-plated brass RCA connectors. The connection is protected with a crimped strain relief and solid brass connector covers that have red & white colored rings for signal identification.
