Introduction to TODN Coaxial High-end Audio Cable Package: Digital coaxial audio cable (RCA male to RCA male) *1, 3.3 feet (1 meter) in length, OD 7 mm,packed in a box.O-C-C Copper Core: Audiophile coaxial cable features Ohno Continuous Cast Copper conductor, are designed to transmit S/PDIF digital audio signals with minimal interference. After 48 hours of burn-in, the sound quality improves even further, fits for 5.1surround sound formats.Dual Shielded: Audio coaxial cable features double shielding (Aluminum Foil & Ohno Continuous Cast Braided) to minimize EMI & RFI interference and signal loss. And delivering clean and stable audio signals.24K Gold-plated Connector: Digital coax cable features corrosion-resistant 24K gold-plated pure copper plugs for reliable connections and reduced signal loss. And pure copper for enhanced conductivity.Impedance: 75 ohm coaxial digital audio inputs/outputs cables which is ideal for audio/video applications, like TVs, CD, DVD players,subwoofer speakers, home theater, amplifiers. Ensure the cable impedance matches your equipment. High fidelity, no noise TODN cables improve sound quality Stronger shielding, less noise Built with two layers of shielding, the high-density shielding net and tin foil shielding layer are constructed with single crystal copper, which can shield more than 99.99% of interference signals Pure copper plug shell Durable, wear-resistant, corrosion-resistant, and anti-interference Plated with 5 thick 24K gold plug Increase conductivity, corrosion resistance, and oxidation resistance to make connections more stable and signal transmission faster. Cable diameter 7mm, AWG=5 The thickened conductors allow more current to pass through, thus improving the sound quality; the nylon braided jacket withstands daily wear & tear. Strong compatibility Suitable for devices such as players, amplifiers, CD players, DVD players, TV boxes, etc
