Audio receivers with 3 RCA inputs

≤ 3 RCA

— the presence in the audio receiver of linear inputs of the RCA standard in the amount of not more than three. RCA ("tulip") is one of the most common interfaces for working with a linear signal, it is he who is most often used in consumer-grade audio equipment (including receivers) to connect audio system components. With this connection, two connectors are needed to transmit stereo sound (separately for the left and right channels), so one input means a pair of RCA connectors. The choice for this parameter depends on how many signal sources (players, tuners, etc.) you plan to keep connected to the audio receiver at the same time. If there are three or fewer such sources, it is worth choosing from this category of models, so as not to overpay for extra connectors that are unnecessary in fact.
