Power Source Connections - Toa NX-100 User Manual

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.

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.

8.3. When Simultaneously Using the 24V DC Power Supply and the AC Adapter
When both the 24V 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 24V 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.

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
PLUGS, for connector connection procedures.
Note
When noise interference affects voice output,
connecting the unit's FG terminal to the ground
terminal of the connected amplifier or mixer may
improve the condition.
