8. POWER SOURCE CONNECTIONS
8.1. When Using a 24V DC Power Source
Connect a 24V DC power source to the unit's DC INPUT terminal.

Notes
• Be sure to connect the unit's FG terminal to the
ground terminal of the amplifier or mixer.
• The DC power supply must have a capacity of
over 200 mA.
• The range of input voltage to be fed to the DC
INPUT terminal should be between 21.6 V and
26.4 V DC. If the input voltage exceeds this range,
the unit may malfunction or fail.
• Refer to
p. 10, CONNECTIONS TO TERMINAL
, for connector connection procedures.
8.3. When Simultaneously Using the 24V DC Power Supply and the AC Adapter
When both the 24 V DC power supply and the AC adapter are simultaneously used, the AC adapter takes
precedence. However, should power from the AC adapter be interrupted due to a power failure, etc., the
power supply will automatically switch over to the unit's 24 V DC power source. Connecting a battery directly
to the DC INPUT terminal also permits it to be used as backup power supply during a power failure.
NX-100 only
8.2. When Using the AC Adapter
Connect the AC adapter* to the unit's AC adapter terminal. Pinch the cord with a clamp and securely fix it.
* Use the AC adapter AD-246 (optional) or the equivalent. As for the usable adapter, consult your TOA dealer.

Ferrite clamp(supplied with the NX-100S only)
This figure represents the NX-100S.
Note
When noise interference affects voice output, connecting
the unit's Earth terminal (FG terminal for the NX-100,
SIGNAL GND terminal for the NX-100S) to the ground
terminal of the connected amplifier or mixer may improve
the condition.
Mount the ferrite clamp (supplied with the NX-100S) on the cable in a way that the cable is looped
one turn as illustrated. (This countermeasure is for complying with the CE marking requirements.)
