Connect the output of your cassette player to the input of the standalone CD recorder. Most cassette players have stereo RCA outputs which can be connected to the stereo RCA inputs of a standalone CD recorder. However, some cassette machines only have quarter-inch outputs. In this case, you will need a special stereo RCA to quarter-inch cable, which can be purchased from any store that sells home audio equipment or musical supplies.
Put the CD recorder in standby or monitor mode. Most CD recorders will have a button on the front clearly labeled as either standby or monitor, however some recorders only require that you press the record or play button one time to engage monitor mode. Check your manual if there is not a button on the front panel.
Begin playing the cassette. Watch the LED or light meter on the front panel of the CD recorder and check to make sure the input volume is appropriate. You want the input volume to be as close to 0dB as possible during the loudest part of the source material. If your CD recorder does not have a clear decibel meter, you can make sure the device is receiving the appropriate input level by keeping the display on the meter out of the red area. To confirm that there is no distortion on the CD, you may need to watch the meter for a few minutes before recording.
Insert a blank CD into the CD recorder. Begin recording on the CD recorder and then start the source material. Once the track has recorded, stop the CD player and then the cassette player. If you want to record more individual tracks, simply repeat the process as needed.
Finalize the CD if your CD recorder requires it. Finalization allows the disc to be played in other CD players besides the one it was recorded in. Some machines do not require this step. If you are unsure about your particular CD recorder, you should check your owner's manual.
