Can an RCA cable go bad?

Do RCA Cables Degrade Over Time? RCA cables degrade for the same reasons that HDMI cables do. They have exposed metal connections, and the joint between the cable tubing and the plug is vulnerable to wear. Because the plug is a single electrical signal, it wont be as susceptible to signal degradation due to rust.

Are RCA outputs line-level?

RCA (phono) connectors are used for turntables, which have very low signal levels, and for DJ controller outputs, which have line-level outputs that can connect directly to power amps.

What is a high to low converter?

What is RCA line level?

A higher sensitivity number means the output of the mic is hotter, offering greater voltage output for an identical input signal.
