UX24 consoles can generate two independent audio streams and decode one incoming audio stream.

​
Available streaming types

  • Streaming 1 (outgoing)
    Uses RTP protocol, ideal for transmitter site link (STL).
  • Streaming 2 (outgoing)
    Compatible with Shoutcast/Icecast servers for internet broadcasting.
  • Streaming 3 (incoming)
    Can be RTP or public HTTP streaming.
    When enabled, the received audio is automatically decoded and switched, replacing the AES-1 input.

​
Signal source and send level

Streaming uses the PROGRAM signal taken from AES-1 output, both for Icecast/Shoutcast server upload and RTP audio stream. The default output level (gain=0) is -20 dBfs referenced to 0VU (1 kHz @ 0VU = -20 dBfs).
Gain is adjusted from SETTINGS → OUTPUTS screen.
If you change the AES-1 output gain, the streaming send level will also change.

​
Streaming services configuration

It’s done from the SETTINGS screen under STREAMING option.
It shows four tabs to configure outgoing streaming services (UP-STREAM and RTP Link); incoming (DOWN-STREAM) and network options.

​
UP-STREAM (TX)

The UP-STREAM tab allows configuring an Icecast or Shoutcast broadcast server to publish the program signal. UX24 Config Icecast

​
UP-STREAM Icecast/Shoutcast

  • ENABLE/DISABLED: Enables or disables streaming transmission when changes are confirmed by pressing APPLY.
    To optimize system resources, keep it stopped when service is not in use.
  • PROTOCOL: Defines if server is Icecast or Shoutcast type.
  • SERVER IP: Server destination IP address.
  • PORT: Server TCP listening port.
  • MOUNTPOINT: Unique name that identifies the stream on the server.
  • Stream NAME: Name that identifies the stream.
  • CODEC: Transmission audio format (Opus or MP3).
  • QUALITY: Bitrate for encoding
  • PASSWORD: Access password for publishing (if applicable).
  • APPLY: Applies and saves changes and starts or stops transmission (according to ENABLE/DISABLED status).
Configuration parameters for Icecast/Shoutcast are provided by the server provider.
The RTP LINK tab allows configuring streaming transmission to a specific IP address, for example, to send the program signal to a transmitter site (STL).
Implementing an RTP link requires advanced network configuration knowledge.
UX24 RTP link configuration
  • ENABLE/DISABLED: Enables or disables RTP streaming when changes are confirmed by pressing APPLY.
    To optimize system resources, keep it stopped when service is not in use.
  • DESTINATION ADDRESS: Destination IP address.
  • PORT: TCP transmission port.
  • CODEC: Audio format for RTP (PCM / MP3).
  • QUALITY: MP3 bitrate or PCM sampling rate.
  • GPO: Enables sending on-air light (Tally Light) signals via TCP/IP for compatible Solidyne equipment.
    • Studio A and B (lines 1 and 2 respectively)
    • Studio B and A (reversed order)
    • A+B (signal activates on both lines, regardless of active studio)

​
Down-Stream (RX)

Allows configuring an incoming stream. When DOWN-STREAM module is activated (ENABLE), the decoded audio is internally routed to AES-1 input, which changes its name to STREAM-1.
In this mode, the AES-1 connector on the rear panel is disabled.
  • RUN/STOP
    Starts or stops streaming decoding when changes are confirmed with APPLY.
    To optimize system resources, keep it stopped when service is not in use.
  • PROTOCOL
    Defines the incoming stream type. The following formats are supported:
    • Public HTTP and MMS streams encoded in PCM 16 (44.1/48 kHz), MP3 or Opus.
    • RTP streams in PCM 16 (44.1 kHz) and MP3.
  • SERVER URL/IP
    Name or IP address of the server generating the stream.
  • PORT
    TCP port where the stream enters.
    Default value: 0.
  • MOUNTPOINT
    Unique name that identifies the stream.
  • APPLY
    Applies configuration changes.

Network (Streamer Module)

General network settings for the UX24 Streamer module (not to be confused with web control access). UX24 Streaming Ethernet Configuration By default, the IP address works in dynamic mode (DHCP). The assigned address is shown on the main screen as STREAM IP. Accessing the streamer module’s IP address from a computer on the network will allow viewing and configuring all its functions.
