4-2. When Signal Mode Is NOT Set correctly
MODE
LED on the front panel flashes or turned off when power is turned on after installing a
USF-105DADA into a USF frame.
When a USF-105DADA is installed in a USF-212S,
Board Settings
in Web GUI are indicated as
Incorrect
(Check FRONT CARD. S2, S3, DS1 and DS2 settings.). See Sec. 7
“Web GUI” for
details.
The output port is fixed to 0V. See Sec. 2-2
“Rear Panel” for details on output port details.
5. Output Gain Adjustment
When USF-105DADA distribution is in LTC or Word Clock mode, output gain can be adjusted using front
panel volume controllers. Gain adjustment is available for output ports 1 to 5 respectively.
Adjustment ranges from -3dB to +3dB.
6. Input Signal Detection
USF-105DADA signal detection differs with the distribution mode.
AES Distribution Mode
Digital audio input signal is detected when the sample frequency is from
32 to 96kHz. If a signal with a sample frequency different from 32 to 96kHz
is input, 0V is output from the
DIGITAL AUDIO OUT
port.
LTC Distribution Mode
For an LTC input signal, if a signal with a frequency different from about
950Hz to 13kHz is input, 0V is output from the
DIGITAL AUDIO OUT
port.
Word Clock Distribution
Mode
For a Word Clock input signal, if a signal with a frequency different from
about 31kHz to 200 kHz is input, 0V is output from
DIGITAL AUDIO OUT
port.
USF-105DADA
Volume controllers for output gain adjustment.
Outputs 1 to 5 are adjusted in order from the left controller.
