Here we propose a perfect use-case for ASDS product. The system is suitable to work in big areas, like malls, galleries or airports.

The analog and digital audio distribution usually need of dedicated infrastructure like wires (70/100V lines), informatic networks, amplification systems and centralized control. The poor ductility and the initial high cost of these infrastructures has led us to create ASDS system.

To distribute the audio in a digital multichannel format we use only the common existing informatic IP network (cat.5/6) LAN or WAN with audio in complete synchronicity between different local client devices.

Below an example of installation schema:

The installation of the part called Server is simple: it will be enough to have 220V power supply and an ethernet cable connected to the informatic network. Once installed the system will be fully programmable by our smartphone / tablet application, where you'll find various menus to distribute the available audio channels on the different clients connected in the designated areas.

The configuration of inputs and signal that you want to distribute on areas includes 1 line-in input or to choose from 5 different channels that can be use with internet radios or songs saved in an USB storage device.

In our example we are using some internet radios and a playlist generated with the USB pen content.

When the Clients are connected in the different areas to serve the application will find automatically the devices on the network (in our case have been installed 7 devices in different areas), after that we can associate the areas to a specific audio source.

The Cloth and Gallery zones will benefit the same audio source because they are adjacent. Via our protocol the visitor that walking through will not notice the sound difference going through from a zone to the other. The audio is in complete synchronicity and he will not perceive no delay or lag in stereo channels.

We choose different sources for the different areas so we can diversify the audio content in the mall.

The "paging" feature to send dynamic content recorded in realtime is request by several realities. A dedicated person to create announcements will have a dedicated app "Voice" section, where he can register in realtime and send it to the different zones. If there are repetitive messages is possible to schedule them in a USB playlist.
