Inputs are the physical ports on your devices that send and receive signals in order to play video and audio. Physical wires are plugged into these ports to connect your devices. Each port has a name, and can only have one device connected to it.
To figure out which inputs are used for each device, you've got two options:
- Use your old remote control to change the input on your TV or audio device and see which device appears on your screen.
- Follow the cord that connects the device to the TV or audio device, and see what the input port is labeled.
When Ray asks you to select inputs, the key things to remember are:
The TV input is the receiving port on the TV set. This could be the same input for some or all your devices if they connect to the TV via an audio device. For example, a common setup is to connect each device into an A/V receiver, which alone connects out to the TV. So for all these devices, the "TV input" is the TV's port that receives the A/V receiver's cord.
The audio input is the receiving port on the audio device. This could be the same input for some or all your devices if they connect to the audio device via the TV. For example, a common setup is to connect each device into the TV, and then connect the TV out to a soundbar. So for all those devices, the "audio input" is the soundbar's port that receives the TV's cord.
