Mexico. There are projects that delight because of how complex and demanding they can be. When SPR, Public Broadcasting System of the Mexican State, asked us for our solution, it told us that another manufacturer could not deliver the complete solution so they were doubtful if it would be possible to put together a project of such magnitude that it would bring together radio audio, satellite, video, control, routing, conversion, processing, distribution with the best quality and that accepted Livewire. Dante and AES67 on the network.
Telos Alliance offers an ecosystem that fills all the nooks and crannies needed for a professional audio installation that meets all expectations and needs.
In this project, AXIA Quasar audio consoles were installed with motorized faders, multiple work profiles, multiple work layers, an infinity of audios available from more than 20 virtual radios from 5 computers/servers. Through Telos Nodes we converted and interfaced with SDI, Analog, and digital AES/EBU to manipulate via AES67 AoIP.
Control by virtual and physical buttons was required to change and route signals in blocks of 20 to go live with the same signal and to be able to return to each one independent according to its corresponding channel. We carry out the control via our Pathfinder Core Pro control solution through logics and macros, and commands to control multiple equipment and in turn be able to confirm the presence of signals, as well as automate the lack of signals and confirm meter levels for each of the desired points.
Another requirement of the project was the conversion of Dante audios to AES67, as well as routing of any audio present in the network to any other place in the network, sharing audios throughout the radio and television network, as well as live and automation, this was carried out through our JUNGER AIXPRESSOR solution with the capacity to receive DANTE, SDI, Analog and Digital and even be able to process the signal of your choice in order to adjust "Loudness Control" and processing, and support deficiencies that come from the original shared material.
Although the requirement was to deliver in AES/EBU to satellite encoders, we could have delivered FM and/or Streaming directly from our OMNIA solutions.
Telephone hybrids were incorporated into the network, as well as Mic to AES67 converters all through the Telos Alliance network.
We added to the solution 3 Intercom Desktop Telos Infinity to be able to intercommunicate between floors/work floors all over the same AoIP network.
The real value is in manipulating and monitoring all the signals with the best possible AES67 audio, signal scanning in the same network, as well as control of them and most effectively having been able to make an installation in a few days so the project required to be completed in time to go on air.
Needless to say, the equipment moved from the 3rd floor of a building where the audio console resides and multiple video and audio signals are received, as well as cabin and automation microphones that are located on the 12th floor where the audios are shared through a fiber optic network and the outputs to the signal to the satellite on the 13th floor are also shared. 4 CISCO professional switches were used to interact the network.
The project has been very well received with high-level results and prompt installation according to the benefits of AoIP for its ease, speed and reliability, even lowering costs in cabling, time and security, as well as the ability to share all audios in multicast.
The project was carried out together with One Media/Broadcast Depot and coordinated the support and installation together with Aarón Cruz Valle - all providing valuable help in the assembly and configuration of the complete system, as well as other brands added to the solution.
