Analog Inputs and Outputs:DVD and CD players also have analog outputs. This connection is optional, except in the event that your receiver or amp has only analog inputs or if you are connecting the player(s) to a television set with analog (only) inputs. If necessary, connect the left and right channel analog outputs of the player(s) to the analog [inputs] of the receiver, amplifier or television. Analog tape players, such as a cassette deck have only analog connections, inputs and outputs. Connect the left and right channel analog outputs of the cassette deck to the left and right channel TAPE inputs on the receiver or amplifier. Connect the left and right channel TAPE OUT outputs of the receiver or amp to the left and right channel TAPE IN inputs on the cassette deck.
