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.

1. 1. Prior to Starting
1-1. Overview
The USF-105DADA is a digital audio distribution amplifier that can be installed in a USF frame. The
USF-105DADA supports AES/EBU signals and is capable of producing up to 5 outputs from 1
input.
LTS and Word Clock signals can be supported by changing the signal mode.
Distribution numbers can be extended using multiple USF-105DADAs.
1-2. Features
Installs into USF frames
1 input 5 distribution outputs
Supports AES/EBU, LTC or Word Clock signals for 5 distribution outputs
Audio output gain adjustable per Out port for LTC or Word Clock signal distribution
SNMP monitoring available (when installed into a USF-212S frame)
Up to 4 USF-105DADA can be installed to extend distribution up to 20 outputs.
Limitation on installation methods may apply.

IMPORTANT
Maximum 7.5Vp-p signal is output from a DIGITAL AUDIO OUT port. Check that the signal mode
is set correctly and the output signal level meets the equivalent level of a connecting device to
prevent damage to the device. Change the signal mode after dis-connecting the DIGITAL
AUDIO OUT port, then check the output signal level before re-connection. If the signal mode has
been incorrectly set, no distribution signal is output. (See Sec. 4 “Signal Mode Setting”)
