Acoustic systems with RCA input
RCA
— initially, RCA is the name of a hardware connector that allows different application formats; however, in this case, a very specific option is implied, namely, inputs for working with an analogue audio signal. Most often these are inputs for linear audio, installed in active acoustics; however, occasionally you can also find passive speakers (usually low-power) connected to the amplifier via RCA.In general, this interface does not differ in noise immunity, but its capabilities are quite enough at least for home acoustics, including quite advanced ones. Note that with this connection, each audio channel requires its own connector; therefore, RCA jacks are usually installed in pairs — stereo left and right.
