AUDIO EDIT PREVIEW
SWITCHER
Set the output phase for the audio playback signal when any of the ASSEMBLE,
VIDEO, AUDIO CH1 to CH4, CUE, and TC buttons is lit.
INT : The audio playback signal output phase is the same as the output phase in
the EE mode. Use this setting when editing with a single VTR, or when
previewing while watching the VTR output signal.
EXT: The audio playback signal output phase is the same as the phase of an
input video signal or external reference video signal.
Note
Whichever setting is used, the correct editing results will be obtained. When,
however, you are using an external switcher to switch the audio output signal
from this unit for the purposes of preview, selecting EXT will prevent any muting
or discontinuities in the audio at editing IN and OUT points.
Select the mode of operation of the sampling rate converter for AES/EBU input to
channels 1 to 4.
OFF : No operation
44kHz: Operate. Choose this setting when the input signal sampling frequency is
44 to 48 kHz.
32kHz: Operate. Choose this setting when the input signal sampling frequency is
32 kHz.
809 AUDIO LEVEL METER
DIMMER CONTROL
Set the brightness of the audio level meters.
0 ... 7: Set in this range. 0 is the brightest, and 7 the dimmest.
807 AUDIO OUTPUT PHASE Select the output timing of digital audio playback signals: (SDI and AES/EBU
only). The reference position corresponds to a setting of 80H; when the setting
is less than 80H, the output timing is advanced, and when it is higher than 80H,
the output timing is delayed. (at 80H, 128 samples = approx. 2.7 ms, and 1
sample=approx. 20 µs)
0 ... 80 ... FF : Setting in this range
808 INTERNAL AUDIO
SIGNAL GENERATOR
Select the operation of the internal audio test signal generator.
OFF : No operation
SILNC: Silent signal
1KHZ: At 1 kHz, –20 dB FS sine wave is supplied to all audio input channels.
To turn on the internal audio test signal generator, set this menu item to other
than OFF, then hold the audio signal selection button for CH1 (channel 1) for
three seconds or more. When the test signal generator is turned on, the input
signal indicator in the audio setting display section turns off. To turn off the test
signal generator, press the audio signal selection button for any of CH1 to CH4
(channels 1 to 4).
