Caution

  • Be sure to connect the power supply as the last step. The same applies to PoE supply from the LAN.

Warning

  • Do not exceed the upper voltage and current limits to avoid irreversible damage of the equipment.
  • Connector to connect a microphone on the front panel is powered.

Firmware Upgrade

2N® Net Mic firmware upgrade starts automatically whenever 2N® Net Mic gets connected to the 2N® IP Audio Manager. This guarantees that all connected devices have identical and latest firmware versions. Refer to www.2n.cz for the latest firmware version.

 

2N® Net Mic Configuration

The 2N® Net Mic hardware console allows you to set the buttons via the 2N® IP Audio Control Panel. Refer to the Audio Sources for more details on the 2N® Net Mic settings.

 

Logic input

Connecting the logic input is equivalent to pressing the A button on the front panel of the 2N® Net Mic. To control the logic inputs are two options. The first option is that you are connecting to the input labeled + (galvanically isolated supply +, 7 V) and the input labeled 1 (0 V). The second possibility is that the input will respond to voltage switches to the input labeled 1 (0 V) and GND.

 

Factory Reset

In some cases, it may be useful to reset the 2N® Net Mic factory values using the RESET button on the lower panel. Do this, for example, if 2N® Net Mic ceases to respond, which may be caused by incorrect LAN settings, LAN configuration changes, forgotten password and so on.

Resetting Procedure:

  1. Use a thin rigid tool to press the RESET button on the lower panel.
  2. Keep the RESET button pressed for 10 s.
  3. Release the button.

This operation takes about 50 s. Do not disconnect the device from power supply during this period.
