Settings
Select the output timing of a digital audio playback signal (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. (80H, 128 samples = approx. 2.7 ms, and 80H, 1
sample=approx. 20 µs)
0 ... 80 ... FF : Setting in this range.
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.
For settings other than OFF:
Press the audio selection function selector switch several times until the INPUT
indicator lights. Then press the CH-1 button in the SDI row, the AES/EBU row, or
the ANALOG row and keep it pressed for three seconds or longer. When you
release the button, all of the audio signal selection buttons light and an internal
signal generator produces an audio test signal.
Set the brightness of the audio level meters.
0 ... 7: Set in this range. 0 is the brightest, and 7 the dimmest.
Set the output phase for the audio playback signal when any of the ASSEMBLE,
AUDIO, and AUDIO CH1 to CH4 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.
Select whether or not to apply emphasis when recording analog audio signals.
OFF : No emphasis.
ON: Apply emphasis.
