Hosa DRA-503 S/PDIF Coax RCA to RCA — 3-Meter Digital Audio Cable
DRA-503 Overview
The Hosa DRA-503 is a 3-meter S/PDIF coaxial cable terminated with RCA phono connectors on both ends, purpose-built for interconnecting digital audio components in professional and installed environments. Constructed on true 75-ohm RG-59/U coaxial cable, it maintains signal integrity across the full S/PDIF digital audio bandwidth without impedance mismatch artifacts. The OFC spiral shield provides effective rejection of EMI and RFI, making it suitable for use in electrically noisy rack environments and live production settings. This cable is also compatible with video applications requiring 75-ohm coax.
Serviceable all-metal RCA plugs allow for field repair if needed, reducing long-term replacement costs in touring and installed system applications.
