Open the "Song" page by pressing the Song key. This will allow you to create a new template in which to record your musical parts. Click on the "New" button to open a dialog box. This enables you to pick the desired sampling frequency and choose a 16 or 24-bit rate. Standard CDs are 16-bit, so either choice will yield fine results, but remember that if you opt to go for the optimum 24-bit resolution, the D3200 will limit you to 16 tracks of recording rather than the 32 available at 16-bit resolution.
Name the song by clicking the "Rename" button on the Song page. The resulting dialog box will enable you to click on letters and numerals in order to give your song a name that you'll recognize in the Song menu. Without a name, it will be listed as "New Song 001", which is fine if you only have one song on the machine, but as you record more songs, it will get increasingly difficult to identify songs as numbers. When your song has been named, click the "Ok" button and confirm your choice by clicking on the "Yes" key.
Turn down the "Trim" control knob on Input 1 and connect your instrument to the recorder via the input jack. Similarly, turn down the headphone volume level to zero and plug in a pair of headphones to the "Phones" jack. If you'd rather monitor your performances with speakers rather than headphones, connect your monitor speakers to the "Monitor L/R" jacks. In this case, make sure that the Monitor level knob is turned off to avoid any surge damage to the equipment when plugging in.
Assign your instrument to its own channel by pressing the "Mixer" key and then clicking the "CH Input/Sub-Mixer" button to call up the channel assignment page. Click on the "CH1 Source" icon to assign Input 1 as the source for channel 1. You can now raise the input level of channel 1 to verify that your instrument's signal has been properly routed.
Arm the channel for recording by pressing the "Record" key and the Channel 1 key to select "Record." The Record button will display a blinking red light to signify that it's in a record-ready mode. Play your instrument and slowly raise the Trim level as high as it will go without causing the LED display light to turn red. If it flashes red, the signal will clip, which results in an unpleasant digital distortion. If this happens, slowly decrease the trim level until the LED stops turning red. If you raise the Channel 1 fader as you play your instrument, you will hear the signal through your monitor speakers. If you're using headphones, don't forget to adjust the "Phones Level" knob in order to hear the signal.
Press the "Play" key to begin recording. The Play and Record buttons will both light up to signify that recording has begun. Play your instrument until your performance is complete and then press the "Stop" key. To return to the beginning of your recording, simply hold down the Stop and Rewind buttons simultaneously and then press the Play button again to listen to the results of your recording.
Record a master track to be burned to a CD. Press the "Master" key to enter Record mode, and with the master fader set at "0," press the "Meter" key to play back your song. Check the master level meter to make sure that the signal isn't clipping and adjust the master fader accordingly. Press the Stop key and then the Rewind key to return to the beginning of the song, enter record-ready mode and then press Play to record the master track.
Insert a blank CD into the CD-R/RW drive and click the "Write To CD" button. A dialog box will ask you to pick a desired writing speed that's compatible with the recordable media you're using. The D3200 will then create an image file and then write it to the CD.
