Interesting... so if anything bc of the impedance it might lower the volume/signal?No not at all. 75 ohm is the characteristic impedance of a coax cable. Google it for a proper technical explanation.
Can a 75 ohm digital rca cable be used in place of a regular rca interconnect?
I have a Harmonic tech digital cable (copper) thats not being used. Im using a blue jean rca cable from my receiver as a preamp to an external amp for a center channel. This cable is of more quality but not sure how these type of digital 75 ohm calbes work in place of a regular rca cable.
