14 8920MUX Instruction Manual
Power Up
Table 3 provides the possible input conditions and the output condition
that results and front LED status.
G2_INS
(yellow)
Off G2 audio will not be inserted.
On continuously G2 audio will be inserted.
Flashing
G2 audio cannot be inserted because the existing G2 audio has not been
deleted or replaced.
G3_INS
(yellow)
Off G3 audio will not be inserted.
On continuously G3 audio will be inserted.
Flashing
G3 audio cannot be inserted because the existing G3 audio has not been
deleted or replaced.
G4_INS
(yellow)
Off G4 audio will not be inserted.
On continuously G4 audio will be inserted.
Flashing
G4 audio cannot be inserted because the existing G4 audio has not been
deleted or replaced.
2ND
(green)
Off
First bank of configuration functions is being addressed by the Function
Rotary Switch (SW1).
On continuously Second bank of functions is being addressed.
24b
(yellow)
Off Encoding is 20-bit.
On continuously Encoding is 24-bit.
EDH
(yellow)
Off Normal operation, EDH packet present in incoming SD stream.
On
EDH packet not present in incoming SD stream. The module will report a sig-
nal or PLL (phase lock) loss condition.
Table 3. Possible Operating Conditions
SD Video Input AES/EBU Input Setting Mode(s) Output Condition
Video input present Synchronous 48 kHz
audio input present Pass all syn.AES
asyn.AES
syn.matrix Input signal will be passed to the output with no new group embedded.
Since no new group insertion is selected, AES1 P and AES2 P LEDs
(signal present) will be on if any AES stream is present. G1-4_PR (sig-
nal present) LEDs will be on to indicate any embedded audio groups
present.
Video input present Synchronous 48 kHz
audio input present Auto insert syn.AES
asyn.AES
syn.matrix 8920MUX will insert the input AES/EBU audio into the first
available audio group (G1 through G4) and light the corresponding
G1-4_INS (insert) LEDs. If all groups are occupied, no new group will
be added and the G1-4_INS LEDs will flash.
Video input present Synchronous 48 kHz
audio input present Insert G1, G2,
G3, or G4 syn.AES
asyn.AES
syn.matrix 8920MUX will insert a new audio group with the appropriate group ID
and light the corresponding G1-4_INS LED. If the group already exists,
no new group will be inserted and the corresponding G1-4_INS LED
will flash.
Video input present Synchronous 48 kHz
audio input present Replace G1,
G2, G3, or G4 syn.AES
asyn.AES 8920MUX will insert a new audio group with the appropriate group ID
and light the corresponding G1-4_INS LED. If the group already exists
it will be replaced with the new group and the corresponding G1-4_PR
LED will flash.
Video input present Synchronous 48 kHz
audio input present Delete all syn.AES
asyn.AES All existing incoming audio groups will be deleted and the G1-4_PR
LEDs will flash. If an insert setting is selected, the module will insert
one group and light the corresponding G1-4_INS LED.
