Hosa DRA-500 series — S/PDIF RCA coax

A named 75-ohm RCA coax series for S/PDIF and documented video applications requiring 75-ohm coax.

Also called DRA-500

Signal role, documented direction and evidence scope matter independently of connector appearance.

The useful distinction

Identify the named product or series in its documentation; connector shape alone does not identify this reference.

This reference does not approve a purchase, live connection, rewiring, substitute power supply, performance target or end-to-end compatibility. Source-checked does not mean independently reviewed.

Before you connect

What to check

  1. Read the exact product or series scope.
  2. Confirm the source, destination and every separate signal path.
  3. Read the power and explicit-unknowns fields before using this reference.
