Audio stream generated from another console

The AoIP module can be configured to receive RTP streaming generated from another Solidyne console with streaming support (e.g.: D612, 2600 series, Unidex series, ADA102 coder/link).
The encoding device must have the same firmware (STL).
From factory, the console comes in CODER (Studio Encoder) mode. To receive, it must be configured as DECODER.

Reception configuration (Decoder)

  1. Access the IP module from a web browser (see IP Module Access.
  2. In the top menu, click Location.
  3. Change the mode to → Transmitter Decoder.
    • Factory default: Studio Encoder, generates unidirectional streaming.
    • As Decoder, default values are adopted (only modify IP and ports).
  4. Go to Configuration → Streaming.
  5. In Port, enter the port used in the encoder (the transmitting device).
  6. In URL, leave 0.0.0.0.
  7. Press Apply to confirm.

Buffer adjustment (RTP delay)

The input buffer (expressed in milliseconds) prevents audio interruptions when bandwidth is insufficient:
Audio FormatRecommended Buffer
PCM40-80 ms
Compressed (e.g. MP3)>80 ms (depends on codec and decoding)
Higher buffer → fewer cuts, but greater audio delay.
The optimal value depends on bandwidth and format used.
The audio format is always defined by the transmitting device.

Decoded audio connection

  • Audio received via Ethernet is sent to balanced inputs through external cable (RJ45 to RJ45, provided).
  • Connection: AoIP Output Option → BAL-1 or BAL-2.
  • In DX822 with two AoIP modules: derived output to both inputs (BAL-1 and BAL-2) using special “Y” cable (supplied).

Reception using a computer

It’s possible to receive transmission from a DX/AoIP on a computer with RTP-compatible software.
Recommended: VLC Player (free – videolan.org/vlc).
Format configuration in VLC:
  • PCM16 @ 44.1 kHz, or
  • MP3 in any of its modes.
Other formats may require a SDP payload file. VLC procedure:
  • Menu: Media → Open Network Location.
  • In URL field enter: [protocol]://[source_IP]:[port]
816 Vlc Decoding Jp For example: RTP://0.0.0.0:3030
  • RTP → protocol.
  • 0.0.0.0 → any incoming IP.
  • 3030 → used port.
Some VLC versions accept: RTP://@:3030
