Headphone amplifiers with RCA output
RCA
— RCA is technically a type of connector that can be used for a variety of purposes. However, in this case, a very specific application is implied — in the line-out format (for analogue audio). In this format, one physical connector is responsible for one channel of sound, so this type of output usually consists of a pair of connectors — for the left and right channels.As for use, linear RCA will be convenient primarily for connecting the amplifier to various stationary audio equipment, mainly entry-level and mid-level. This interface itself is not particularly noise-resistant, however, with the proper quality of the connecting wires, it is quite capable of providing more than decent sound quality — quite sufficient not only for everyday use, but also for relatively simple professional use.
