Xantech¿s CPLTCX digital audio signal converter is an easy to install, clean approach to converting S/PDIF digital audio signals from optical to coaxial format. Combine with the Xantech Coaxial to Optical Digital Audio Coupler (CPLCT, sold separately) to provide a long distance alternative using lower cost coaxial cable instead of optical cable. You will need an EIAJ optical cable (Toslink) and a coaxial cable (both sold separately) with RCA style ends. The length should be based on your application.
