Important Safety Warnings
[Power]
Stop
Do not place or drop heavy or sharp-edged objects on power cord. A damaged cord
can cause fire or electrical shock hazards. Regularly check power cord for
excessive wear or damage to avoid possible fire / electrical hazards.
[Circuitry Access]
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 power is disconnected. Capacitors associated with the power supply are
especially hazardous. Avoid contact with any capacitors.
Hazard
Unit should not be operated or stored with cover, panels, and / or casing removed.
Operating unit with circuitry exposed could result in electric shock / fire hazards or
unit malfunction.
[Potential Hazards]
Caution
If abnormal smells or noises are noticed coming from the unit, turn power off
immediately and disconnect power cord to avoid potentially hazardous conditions. If
problems similar to above occur, contact authorized service representative before
attempting to again operate unit.
[Consumables]
Caution
The consumables used in unit must be replaced periodically. 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,
they should be replaced at an early date. For details on replacing the consumables,
contact your dealer.
Upon Receipt
Unpacking

3. Connection
Refer to figure below for connecting the UFH-70ADA to other devices.
Note that before installing the UFH-70ADA into a system frame, you should thoroughly read the
operation manual for the System Frame where you will be installing.
3-1. Connecting Wiring to Terminal Block
To connect audio wiring to the terminal block on the UFH-70ADA rear module, follow the steps
below.
1) Unscrew the cover screws at both sides of the terminal block using a small Phillips-head
screw driver.
2) Remove the terminal block cover forward. Set it aside.
3) Release the port screw on the top of the terminal block by using the same screw driver.
4) Insert the wire end into the port and secure the cable to the port with the port screw.

IMPORTANT
Use AWG16 to 28 wire. Strip the wire shielding so that approximately 5mm of each
wire is exposed.
3-1-1. Balanced Input/Output
For balanced input and output, connect the hot, cold, and shield of the audio signal to their
respective terminals (+, - and G for each).
3-1-2. Unbalanced Input/Output
For unbalanced input and output, connect the analog audio signal line to hot and shield
(ground) line to both cold and shield. After the connection has been made, check the level
and adjust it as required by using the GAIN dial.
