Streaming services

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

​

Available Streaming Types

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

​

Signal Source and Send Level

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

Streaming Services Configuration

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

​

UP-STREAM (TX)

The UP-STREAM tab allows you to configure a Icecast or Shoutcast streaming server to broadcast the program signal.

​

UP-STREAM Icecast/Shoutcast

• ENABLE/DISABLED: Enables or disables the streaming transmission when changes are confirmed by pressing APPLY.
  To optimize system resources, keep it stopped when the service is not in use.
• PROTOCOL: Defines whether the server is Icecast or Shoutcast type.
• SERVER IP: Destination IP address of the server.
• PORT: TCP listening port of the server.
• MOUNTPOINT: Unique name identifying the stream on the server.
• Stream NAME: Name identifying the stream.
• CODEC: Audio format for transmission (Opus or MP3).
• QUALITY: Bitrate for encoding.
• PASSWORD: Access key for publishing (if applicable).
• APPLY: Applies and saves changes, and starts or stops the broadcast (according to ENABLE/DISABLED status).

​

RTP LINK

The RTP LINK tab allows configuring streaming to a specific IP address, for example, to send the program signal to a transmitter site (STL).

• ENABLE/DISABLED: Enables or disables RTP streaming when changes are confirmed by pressing APPLY.
  To optimize system resources, keep disabled when the 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 sample 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 configuration of an incoming streaming. When the DOWN-STREAM module is enabled (ENABLE), the decoded audio is internally routed to the AES-1 input, which changes its name to STREAM-1.
In this mode, the rear panel AES-1 connector is disabled.

• RUN/STOP
  Starts or stops the streaming decoding when changes are confirmed with APPLY.
  To optimize system resources, keep it stopped when the service is not in use.
• PROTOCOL
  Defines the type of incoming streaming. 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 streaming.
• PORT
  TCP port where the streaming is received.
  Default value: 0.
• MOUNTPOINT
  Unique name identifying the stream.
• APPLY
  Applies configuration changes.

Network (Streamer Module)

General network settings for the Streamer UX24 module (not to be confused with web control access). By default, the IP address operates in dynamic mode (DHCP). The assigned address is displayed on the main screen as STREAM IP. By accessing the streamer module’s IP address from a computer on the network, all its functions can be viewed and configured.
