Supply a correct input signal.
Some older monitors support only the 59.94/
60 frequencies. Use a monitor with
specifications supporting the format.
Input a signal with 1.000/1.000 and 1.000/
1.001 that match the system.
If the monitor is a BVM-F24, 25PsF and
29.97PsF cannot be displayed with ×3
scanning, resulting in picture breakup. Use ×2
or ×1 scanning. For 59.94i and 50i, use ASD
scanning.
Check the monitor settings. Try turning it off
and on again.
Countermeasures
To prevent noise and damage to audio monitor
equipment, audio is muted off when switching
modes.
No audio is output when Non Audio mode is
selected. A white box in the meter display
indicates "Non Audio."
When there is no sound from the headphones,
even though the meters are moving, check
whether the volume is set to an appropriate
level.
Noise occurs when the playback frequency is
different from the recorded frequency, because
of the difference in the number of audio
samples. Switch the playback format to match
the recorded frequency.
Change the setting to +48 V ON (except for
internal battery powered microphone).
Set SYSTEM > TEST SG > AUDIO to 1kHz.
Select the test signal again.
