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:
- Use a thin rigid tool to press the RESET button on the lower panel.
- Keep the RESET button pressed for 10 s.
- Release the button.
This operation takes about 50 s. Do not disconnect the device from power supply during this period.
