CD players with 2 RCA outputs
prices on 4 models≥ 2 RCA
— the presence of two or more RCA outputs in the design of the CD player.RCA in this case does not mean the connector itself with the same name, but an analogue audio transmission interface using these connectors. This interface is one of the most popular ways to transfer analogue audio between Hi-Fi and Hi-End audio components; its presence is almost mandatory for CD players generally capable of outputting analogue audio. Note that one RCA output consists of a pair of connectors — for the left and right stereo channels. If there are two or more such outputs, more than one audio signal receiver can be connected to the player at the same time, for example, two sets of acoustics installed in different rooms. And in models with a built-in amplifier (see the relevant paragraph), it may be possible to simultaneously output a signal of different power: to one RCA output — from the preamplifier, to the other — from the power amplifier.
