Precautions
Important Safety Warnings
[Operation]
Stop
Do not place the unit in the place of high temperature and high humidity, dusty, or high
vibrations. Operation other than the operating environment conditions may cause
malfunction, fire, or electrical shock.
[Transportation]
Caution
Handle with care to avoid impact shock during transit, which may cause malfunction.
When you need to transport the unit, use the original or suitable alternative packing
material.
[Circuitry Access]
Caution
Do not remove covers, panels, casing, or access the circuitry with power applied to the
unit. Turn the power off and disconnect the power cord prior to removal. Internal
servicing / adjustment of unit should only be performed by qualified personnel.
Stop
Do not touch any parts / circuitry with a high heat factor.
Capacitors can retain enough electric charge to cause mild to serious shock, even after
the power has been disconnected. Capacitors associated with the power supply are
especially hazardous.
[Potential Hazards]
Caution
If abnormal odors or noises are noticed coming from the unit, immediately turn the
power off and disconnect the power cord to avoid potentially hazardous conditions. If
problems similar to the above occur, contact an authorized service representative
before attempting to operate the unit again.
[Consumables]
Caution
Consumable items that are used in the unit must be periodically replaced. For further
details on which parts are consumables and when they should be replaced, refer to the
specifications at the end of the Operation Manual. Since the service life of the
consumables varies greatly depending on the environment in which they are used,
such items should be replaced at an early date. For details on replacing consumable
items, contact your dealer.

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.

7. Web GUI Setup
Web GUI can be displayed when a USF-105DADA is installed into a USF-212S frame, but is not
displayed when it is installed into a USF-212 frame. See USF-212S operation manual for details on
displaying a Web GUI.
Launch Web GUI and click USF-105DADA from slot no.1 to 12 of the USF-212S. The screen below

9. Extended Distribution Using Multiple USF-105DADAs
Internal Bus Configuration
Applying multiple USF-105DADAs enable you to increase the distribution number via a USF frame
internal bus.
Up to 4 USF-105DADAs can be applied and 20 distributed, from 1 input. Install USF-105DADAs in the
internal bus slot that is the same as for the input signal. (Slot 1 to 4, Slot 5 to 8, or Slot 9 to 12)
Set DS2, and Switch 3 to 7 to increase distribution number via an internal bus. See Sec. 3-4 “DS2
Switches 3 and 4: Input Signal Switches Settings” and Sec. 3-5 “DS2 Switch 5, 6, and 7: Internal Bus
Switch Output Settings” for details on switch settings.
IMPORTANT
When using USF-105DADA units in a USF frame internal bus, apply multiple USF-105DADAs to
extend distributions. Other USF modules cannot be combined with USF-105DADA for this purpose.
When using an internal bus, ensure that the settings do not affect other modules.
