Product Description

Despite the gradual modernisation of audio systems to IP technology, customers are still encountering the need to connect an IP audio system to a traditional music sources such as FM radio stations, CD players or microphones. 2N® Net Audio Encoder can transfer traditional audio sources to IP technology and then ensure audio distribution over an IP network to various destinations.

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 Audio Encoder firmware upgrade starts automatically whenever 2N® Net Audio Encoder 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 Audio Encoder Configuration

2N® Net Audio Encoder allows set audio source to the Session via the 2N® IP Audio Control Panel. Refer to the Audio sources for more details on the 2N® Net Audio Encoder settings. To active the stream use the logic input.

 

Logic input

Connecting the logic input of the 2N® Net Audio Encoder. 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.

Logic input can operate in both latching and momentary states.

When using a switch across the logic input, a stream can be activated by a brief ‘press and release’ to start followed by a ‘press and release’ to stop (latching). Alternatively, a constant press of a switch will activate the stream for the duration that the switch is pressed, stopping the stream upon release (momentary).



Factory Reset

In some cases, it may be useful to reset the 2N® Net Audio Encoder factory values using the RESET button on the lower panel. Do this, for example, if 2N® Net Audio Encoder 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.
