TSIP is a compact digital audio matrix which enables to equip a tramway station thanks to its two 100 Volt 120 Watt integrated amplifiers: one amplifier per output. It also has an IP interface, a message player, an automatic level regulation, supervision of the two 120 Watt lines, two audio inputs and outputs as well as two contact inputs and outputs.

The matrix receives audio signals coming from the Vox@net g2 central system via a TCP/IP network thus enabling the spread of information on the entire tram line.

The matrix configuration is made by embedded web server.

The audio system on the Vox@net g2 network enables to supervise all audio sources and destinations. It enables to use the TSIP matrix as well as the various functionalities: broadcasting messages and paging in a station and/or on all the lines, recording messages with the microphone for later broadcast, placing in a queue pre-recorded messages, event scheduler, interfacing with other MODBUS systems, supervision of loudspeaker lines, follow-up and reporting of error messages. A server PC enables the configuration and use of the Vox@net g2 program.

A MODBUS interfacing with the client's supervision system is possible via the Vox@net g2 software.

The Vox@D paging console specially designed for PA systems on IP works with the Vox@net g2 software. It has a gooseneck microphone, a monitoring loudspeaker as well as a TFT 5'' backlit color touch screen console. Functionalities available from its touchscreen console : skip from one page to another one, selection of zones, groups of zones, ON/OFF mic, chime triggering, reset, low, high or average priority, selection of messages, reading messages, stop messages, microphone paging, setting the volume of the control loudspeaker, start background music,. Configuration of the console is made with an embedded web server.

The Vox@K G2 paging console is also an IP paging console working with the Vox@net g2 software. It has a gooseneck microphone, an audio return loudspeaker as well as a push button (Press-To-Talk, active after Vox@net g2 authorization). Functionalities available from the control console (PC Vox@ customer) are: selection of zones; group of zones, microphone paging, triggering chime, start background music, setting the volume of the control loudspeaker, etc.
