The RP-ADAC2 is a DA converter that connects to a TV with digital output terminals (optical digital, coaxial digital), game consoles such as PS4, PS3, and other AV devices such as Apple TVs to convert to analog audio, and output stereo mini compos and mini amplifiers. If your newly replaced TV does not have an analog output, or you want to connect the audio of the game console to an external amplifier, you can connect the RP-ADAC2 to an analog (RCA, red and white) to amplifiers without digital audio inputs.
