Hey Paul,
Admittedly I am stabbing in the dark here as I don’t have a deck in front of me.
And, once you find the solution, it is likely to be something very simple.
A couple more things to try.
Is the VTR set to REC INHIBIT ON?
(PDF page 22 in manual: Toggling between lit/flashing settings is possible using the VTR SETUP menu item 104 “REC INHIBIT LAMP FLASHING”.)
“5-1-2 Selecting Audio Signals” (Pdf page 118 & 119)
Selecting audio signals to be monitored With the MONITOR L or R buttons at the upper left of the control panel, switch the audio signal output from the PHONES jack and MONITOR OUTPUT L/R connectors as follows.
1. Check the audio level display area in the color display, and make sure that the unit is not in the REC LEVEL/PB LEVEL setting state (with red or blue vertical lines appearing on the left and right of the audio level meter).
The channels for which the signals are currently being monitored are shown by reverse video characters “L” and “R” below the audio level meter.
2. Press the buttons corresponding to each channel, to light the L/R reverse video indications below the audio level meter, and specify channels 1 to 12 with the MONITOR L or R button (both L and R can also be specified).
This setting can also be made using the VTR SETUP menu items 807 “AUDIO MONITOR-L select” and 808 “AUDIO MONITOR-R select”.
This hidden “text” on page 119 might be a red herring, but does suggest that under certain circumstances: If the audio is digital, it will not play on the analogue monitoring….
• The following processes are performed for the selected channels.
– For the input signal, the setting of the VTR SETUP menu item 831 “NON AUDIO SELECT” takes
precedence over that of the menu item 830 “AUDIO INPUT SELECT”.
– For the audio level meters, the whole region lights. Also, below the input signal display, the word “DATA” appears in white.
– The analog audio outputs (output to the MONITOR OUTPUT connector and the PHONES jack) are turned off.
– The audio recording level adjustment itself is possible for the channel for which “NON AUDIO” is selected, but the setting does not affect the recording or playback of DATA.
– Non-audio input channels are selected in stereo pairs.
• When the VTR SETUP menu item 842 “AUDIO INPUT/OUTPUT SAMPLING FREQUENCY” is set to
“96K”, recording/playback of non-audio data cannot be performed.
Page 129:
5-4-5 Playing Back Non-audio Data
Non-audio data recorded on a tape is detected automatically and played back.
When non-audio data is being played back:
• Below the input display in the audio level meter section, the DATA mark lights in white.
• For the audio level meters, all regions light.
• The analog audio outputs (output to the MONITOR OUTPUT connector and the PHONES jack) are turned off.
• The audio output level can be adjusted during non-audio data playback, but output non-audio data is not affected.
Out of interest, is the F6 INS AUDIO button on or off?
On page 137 it describes the editing process using the VTR, which if the wrong buttons are pressed that your VTR could think that it was doing.
Monitoring signals during previewing
During previewing, you can monitor the following video and audio signals on a monitor connected to the recorder VTR:
• Between preroll and IN points: Playback signal of the recorder VTR can be monitored.
• Between IN and OUT points: Playback signal of the player VTR can be monitored in E-E mode.
• Between OUT and post-roll points: Playback signal of the recorder VTR can be monitored.
Depending on the above, it is worth checking menu:
322 AUDIO PREVIEW MODE
On top of that any of the 800 menu items from 807 onwards, could be interesting.
However, if not broke, do not fix it…
Hope this might help.
