SRC BY-PASS
PCM
Mute
Selects audio error sensor mode for each
stereo channel pair of SDI and AES input
audio signals whose channel status
NON-PCM flag is 1.
*1
SRC BY-PASS: Treats audio signals as
NON-PCM. By-passes audio signals through
SRC
*2
, and selects audio clock input in the
NON-PCM signal channel for SDI AUDIO
CLOCK.
*3
PCM: Treats audio signals as PCM (standard
audio signal). By-passes audio signals
through SRC
*2
, and select REFERENCE for
SDI AUDIO CLOCK.
*3
Mute: Treats audio signals as mute signals.
*1 Channel status and Validity Bit of input audio channel status can be checked using a wave
form monitor.
*2 Processes the audio signal as described if 9-3-5 SRC Mode is set to Auto.
*3 Processes the audio signal as described if 9-3-10 SDI Audio Output Settings is set to Auto.
 CH STATUS:
FA-9520 determines whether the input audio signal is PCM or NON-PCM by the NON-PCM
flag in the Audio Channel Status (ACS). If ACS is incorrect the audio signal may cause
improper processing. For such case, this setting may effective processing the audio signal
normally.
IMPORTANT
Use this setting only if there is audio noise or the audio is muted. Otherwise, do not
change the setting from the default setting.

 Validity:
FA-9520 determines whether the input audio signal is PCM or NON-PCM by Validity Bit (V Bit)
in audio signal. If Validity Bit (V Bit) is incorrect the audio signal may cause improper
processing. For such case, this setting may effective processing the audio signal normally.
IMPORTANT
Please use this setting only if there is audio noise or the audio is muted. Otherwise, do
not change the setting from In Data.
