    receivers family (E411, E413, E415 and
    E417), and with the E351 transceiver and
    other devices able to decode RTP audio.

    Can generate up to 100 audio streams


    simultaneously. Each stream can be sent
    to a unicast or multicast destination.

    Two working modes can be configured:


    “Fixed zoning” or “Selectable zoning”.

    E497 24 keys paging console for audio IP systems

    Application
    The image shows a typical IP
    paging application using the
    E497 and/or E495 consoles and
    some ENA series decoders
    (E411, E413, E415 or E417).
    The main function of the E497or
    E495 consoles is send vocal
    messages to the “Emergency” or
    “Advertisement” layers of the
    decoders(*).
    The vocal messages can be
    generated live, from the micro-
    phone, or from files stored in the
    SD memory card.
    The selection of the destinations
    (zones) to send the audio is very
    easy and flexible.
    If more than one console is
    used, the intercommunication
    between them allow to avoid
    usage conflicts. The destinations
    that are in use by one console are disabled temporally in the others.
    Also, the line input can be used to send audio from an external source. This can replace the background music
    generation system in some applications.
    As an option, it is possible to include the ability to send recorded messages in a scheduled time basis (add the
    “-T” option to the purchasing code)

    (*) See the document “ENA system description” for a detailed description of the audio layers and priorities system.

    Audio formats Simple configuration
    The E497 sends audio to the network using the RTP Configuration is done through the embedded
    standard and one of the three following uncompressed web server specially designed for an intuitive
    audio formats: use.
     G711-A: Sampling at 8 kHz and 12 bits per sam-
    ple, coded in 8 bits. This is the most common au-
    dio format used in VoIP systems. It yields a good
    voice quality with small bandwidth consumption. Is
    compatible with the ENA decoders and the E351
    transceiver.
     PCM11025: Sampling at 11.025 kHz and 16 bits
    per sample. Better audio quality than G711-A.
    Compatible with the ENA audio decoders.
     PCM32000: Sampling at 32 kHz and 16 bits per
    sample. Very high sound quality. Compatible with
    the E351 audio transceiver.
    The uncompressed audio formats allows to have low
    latency values.
