Product Description

2N® Net Audio Decoder Lite is a LAN audio converter designed for public sound distribution through the 2N IP Audio System. It is connected to the 2N IP Audio System via the local area network (LAN). It communicates with the 2N® IP Audio Manager, receives the audio stream, decodes it and converts it into an analogue signal. 

2N® Net Audio Decoder Lite can be controlled by two front panel buttons or an infrared remote controller. 2N® Net Audio Decoder Lite is equipped with a digital input and output, which extend the converter options and may be helpful in special applications. 2N® Net Audio Decoder Lite helps you extend the internal FLASH memory using microSD memory cards. Use the integrated Telnet server to make basic settings for connection of 2N® Net Audio Decoder Lite into the LAN (refer to the Basic Parameter Settings). Apply the 2N IP Audio System  software for configuration and use of all functions (refer to the 2N® Net Audio Decoder Quick Start and 2N IP Audio Administration manuals for more details).

Electric Installation:

It is very easy to connect 2N® Net Audio Decoder Lite electrically. Follow the steps below to avoid equipment damage or electrical injury:

  1. Connect the speaker, headphones or an external amplifier.
  2. Connect the digital input and output.
  3. Insert the microSD card.
  4. Connect the UTP cable.
  5. Connect a 12 V power supply.

Headphone/External Amplifier Connection

2N® Net Audio Decoder Lite is equipped with a headphone/external amplifier connector. The 3.5 mm jack is available on the front panel.

 

Digital Input and Output

2N® Net Audio Decoder Lite is equipped with a relay switch for light signalling/external amplifier/alarm/activation. The output is available on terminals marked LOGIC OUT and allows for switching of up to 24 V / 1 A AC/DC loads. Program the output either as N/O (normally open) or N/C (normally closed).

Warning

  •  Do not exceed the upper voltage and current limits to avoid irreversible damage of the equipment.

2N® Net Audio Decoder Lite is equipped with a digital input for an optional button, sensor of movement or other applications. This input is available on the LOGIC IN terminal. From 5 to 24 V DC voltage can be applied to the input against the ground terminal marked DC IN -. In the case of external button, the DC IN + terminal can be used, see the figure below. 

Warning

  • Do not exceed the maximum voltage values (24 V) applied to the LOGIC IN input to avoid irreversible damage of the equipment.

Power Supply Connection

2N® Net Audio Decoder Lite can be connected to a standard local area network using a LAN interface via the RJ–45 connector on the back panel. Always use CAT–5d or higher class cables for reliability reasons. The LAN interface is equipped with the Auto MDIX function for automatic detection of a straight or cross–over cable. 

2N® Net Audio Decoder Lite can be fed using a 12 V DC / 2 A (Part No. 914102E) power supply, or another power supply on condition that you keep the nominal values included in the Electric Parameters subsection. 

Connect the 12V DC power supply either to the back panel supply connector marked DC IN, or terminals marked DC IN + and DC IN -.

Warning

  • If you use an adapter other than the recommended one, do not exceed the nominal supply voltage value of 12 V. Also make sure that the supply voltage polarity is correct. Exceeding nominal values and/or incorrect connection may lead to irreversible damage of the equipment.

2N® Net Audio Decoder Lite Factory Reset

In some cases, it may be useful to reset the 2N® Net Audio Decoder Lite factory values using the RESET button on the back panel. Do this, for example, if 2N® Net Audio Decoder Lite 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 back panel.
    2. Keep the RESET button pressed (for approx. 15 s).
    3. Release the button as soon as the LED starts shining violet.

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

Firmware Upgrade

2N® Net Audio Decoder Lite firmware upgrade starts automatically whenever 2N® Net Audio Decoder Lite 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.
