Thoughts on using? Counted it up and my receiver alone has 63 unused RCA jacks

Do you have an issue? If not... save your $$.

You would probably have more potential to have problems with poor cables/connectors before unused/open RCA ports.

That just means that you don't have enough stuff!

 

Well... then go buy a CD player, Phonograph player, Cassette player, CDR/MD player/recorder, VCR, VCR 2, DVD player, and, and, and....

 

With the invention of HDMI, the one cable system is a reality.  However, AVRs will still offer many RCA inputs for legacy systems.

 

The only unused RCA's on the back of my AVR are the pre-outs.  Plus whatever connection are on the front...

 

As a matter of fact, one of my back RCA plugs is piggy-backing on another.

 

I however, do not have HDMI on my AVR, but I have a lot of legacy equipment.

 

Back on subject though, I do not believe that unused RCA connection need to be plugged.

The reason for putting shorting caps on RCA jacks is if you have problems with noise or crosstalk.

This usually would only apply to inputs.

If its not broke, don't fix it!

The best reason for putting caps on them is to prevent corrosion over a period of years, but gold-plated ones do not corrode significantly, so don't worry about those that are gold-plated.

There is no performance issue.

And even then it's usually just the phono inputs .
