Chapter 6 Maintenance
Cause/Remedy
Confirm the level of the sound output from the player by referring to the player's
instruction manual. According to that output level, set the INPUT LEVEL switch on
the rear panel of the unit so as to obtain an optimum level.
If you are not clear about the player's output level, try the following procedures.
1 Specify the output level by types of audio output connectors available on the
player.
• If the player is equipped with phono jacks: –10.
• If the player is equipped with XLR connectors: +4 or –2.
2 Set the AUDIO INPUT switch on the front panel to AUTO and play back the
tape which you intend to use for playback. When the playback audio level is at
its maximum, if the audio level meters exceed 0 dB, set the INPUT LEVEL
switch to the lower step (+4). Or, set AUDIO INPUT switch to MANU and turn
the AUDIO REC LEVEL control knobs to adjust the recording level. The
recorded sound at the portion where the meters exceed 0 dB will be distorted.
• You are trying to dub the sound onto an HDV or DV-formatted tape.
t Sounds can be dubbed only onto a DVCAM-formatted tape (recorded) in the
32 kHz audio mode (4-channel). If the unit detects the following, audio
dubbing will automatically abort, an alarm message will be superimposed on
the LCD monitor and on an external monitor.
– A blank portion
– A section recorded in other than 32 kHz audio mode (4-channel)
– A portion recorded in other than DVCAM format
• You have tried to dub the sound onto channels 1 and 2.
t Only channels 3 and 4 can be used for dubbing. You cannot dub the sound
onto channels 1 and 2.
• Set the AUDIO MONITOR SELECT switch depending on the audio channel you
want to output the sound to.
• When the audio mode is 2-channel and the AUDIO MONITOR SELECT switch is
set to CH-3/4, no sound is emitted whether the format is HDV or DV.
t Set the AUDIO MONITOR SELECT switch to MIX or CH-3/4.
t Use the correct setting for [HDV/DV SEL] in the [IN/OUT REC] menu in
accordance with the equipment to be connected.
• The INPUT SELECT switch is set to a setting other than HDV/DV.
t Set it to HDV/DV.
• The editing controller or the editing software is not compatible with the unit.
t Refer to the instruction manuals of the controller or the software and consult
their manufacturers.
