What voltage should RCA cables be?
A good quality RCA audio source should have a voltage rating around 1-2 Volts and a low impedance. The voltage is the “strength” of the signal and the “impedance” relates to signal integrity once the RCA is plugged into the amplifier.
Do RCA cables have positive and negative?
A: RCA cables are signal wires. There is a positive and negative in each. They just signal to the amp.
How does RCA output work?
A simple RCA cable has three color-coded plugs extending from one end that connects to three corresponding colored jacks on the back of a TV, projector, or another output device. It carries audio and video signals from the component device to the output device (i.e. a television or speakers).
