• Remove: All incoming HANC packets are dropped before embedding any
new audio packets.
NOTE: 2048 x 1080p/PsF 29.97 and 30 formats support a maximum of 8 channels of
embedded audio. When one of these formats is present and embedding is turned
on, the PASS HANC setting will be ignored and all incoming packets will be
dropped before embedding any new audio packets.

input Stream A or the audio channels of input Stream B for disembedding.
This setting also controls whether output Stream A or output Stream B will
receive embedded audio. This control has no effect if a 3G Level B signal is not
detected. Select one of the following settings:
• Stream A
• Stream B
Analog Audio Level
Full Scale Digital (dBu) -
Select from the following:
• +24 dBu
• +18 dBu
• +15 dBu (professional)
• +12 dBu (consumer)
About Audio Levels
Professional audio equipment has much higher levels than consumer equipment.
A 0 VU reading corresponds to +4 dBu. Connecting a profes4 dBu device
to a consumer audio input (-7 to -8 dBu) may produce overloading, whereas the
output of a consumer device probably does not have sufficient power to drive a
professional audio input. With consumer and semi-professional audio equipment,
a VU reading of 0 dB is typically referenced to -10 dBV, which is equivalent to -7.78
dBu.
