16-bit stereo = highest quality sound, produces CD quality sound, 2 channel sound on
one track
12-bit stereo (2 channels) = records on 2 of the 4 available channels, leaving the other
channels available for the addition of sound, music, narration, etc.
12-bit stereo (4 channels) = used for simultaneous recording on four channels which
means audio can be outputted as four independent channels. Audio quality is slightly
lower.
XLR Microphones : balanced, contain a noise-cancelling cable that greatly reduces
unwanted interference
Locked and unlocked audio : unlocked = always completely in sync with the video.
The difference is found with the number of audio samples per video frame. Locked –
the sample rate per frame of video is fixed, while with unlocked audio allows for
some slight variations in the number of samples per frame.
Terminals vs Tracks : Audio 1 and Audio 2 refer to the physical location of the
audio inputs. Audio 1 terminals appear on the back of the camcorder, Audio 2
terminals are on the right side of the handle. Stereo 1 and Stereo 2 refer to the stereo
tracks available on the tape.
Audio Monitor : only use when using 12-bit (Stereo 1 and 2) mode. If you use the 16-
bit mode, then the sound is fixed in Stereo 1 only.
Camera Recording : You can select the sound source you want to record: Stereo 1, 2
or a mix of both
Selecting the audio output in VCR Playback Mode: When playing back a tape in

If the sound was recorded in 16 bit mode, it only contains Stereo 1 sound and you
