How to add sound to a pre-recorded tape (audio dubbing) on the GL2.


You can add sound to the original sound on a pre-recorded tape from audio devices (AUDIO IN) or with the or external microphone (MIC. IN). The original sound will not be erased. If there are non-recorded portions on the tape, or portions recorded in a mode other than SP mode, or with 16-bit or 12-bit 4-channel sound, dubbing will stop. If your tape has not been recorded in SP mode with 12-bit sound, we recommend dubbing your original tape onto a blank tape using the GL2?s analog line-in function, then dubbing audio onto the new tape. Make absolutely sure to set the audio mode of the new tape to 12-bit and the recording mode to SP.

To connect other audio devices:



  • No video picture will be output via the AV terminal. Check the picture on the LCD screen, viewfinder or a TV connected to the S-video terminal. Check the sound using the speaker or headphones.

To connect an external microphone:



  • When using the built-in microphone for dubbing, make sure that no cables are connected to the MIC terminal.

  • If you connect a TV to the S-video terminal, you can monitor the picture on the TV screen. Use headphones to check the sound.


Turn the camcorder?s POWER switch to PLAY (VCR) and move the camcorder?s TAPE/CARD switch to TAPE. Load a recorded cassette.

  • Make sure the REC/SAVE tab on the cassette has been slid to REC (closed position).



Do not connect/disconnect any cables to/from the camcorder when dubbing audio or preparing to dub audio.
