Broadcast Audio Sync Distribution IP

BasdIP allows to transmit one or more high quality MPX channels or stereo audio (lossless or lossy) over IP from a server to different clients with a complete synchronicity.

The system can be used in two different ways: MPX or line audio L&R.

The first can bring the entire MPX signal coded with stereo and RDS data using a 96Khz bandwidth. The second brings the pure audio with a 48Khz bandwidth where eventually it will be necessary recode the output of the client.

With two or more clients that receive the same channel, MPX / audio output will be in complete synchronicity. Connecting different distant but adjiacent transmission systems on the same listening areas the radio listeners will never perceive any kind of delay betweem them.

Server

The BasdIP server can brings differents sources, it has one or more (optional) MPX and Line IN input. We also have 2 different players that can stream simultaneously a streaming URL to the different connected clients (in audio mode). The clients using the same input source will receive and play in sync (both in MPX and audio).

On the server there is an MPX output and/or stereo line output that perform in the same way that client does. So is possible to connect a local broadcast system and maintain the audio in sync with the other connected clients.

Client

The client is an ARM device that can play what the server transmit. It has on board an Ethernet connector, one MPX output and one stereo line output. The data flows from server to clients through a tunnel OpenVPN. So you can connect your devices to a normal router with a Internet connection that has enough bandwidth without particular configurations.

Client can have different configurations:

• RS232/485 port to communicate with encoder RDS or TX connected in local. For example you can read realtime status or send custom data
• Multichannel GPIO that can be used to power off / on with a scheduling or in realtime different devices.
• microSD with audio files that can be used in emergency mode when the client lost connection to the server.
• MPX or Line input for external receivers that can be switched with a scheduling, remote command or in emergency
• Streaming URL

Dashboard WEB

The system is accessible by a real time dashboard web (in the near future with a Mobile application too) where you can check the system status, send differnet commands to the client and eventually read status of different external devices.
