What are Inputs?
Home electronic devices such as televisions, VCRs and stereo receivers, require an audio and/or video “signal” to perform their intended purpose (playing audio or video). This “signal” can come from a cable company, an antenna, a satellite, a VCR, a DVD player, etc. Typically, the signal is sent via a cable, or multiple cables that plug into connectors on your device. The connector that the cable plugs into is called an “input”. There are different types of inputs, and sometimes a single device can have more than 1 type of input. Examples of different inputs include RCA inputs, co-axial inputs and optical inputs.
