ALL THE AUDIO OF THE ARGENTINIAN CADENA3 CORDOBA OVER AEQ BC2000D

AEQ SYSTEL6000 MULTI-CONFERENCE SYSTEM MANAGES ALL THE TELEPHONE CALLS OF THE SEVERAL STUDIOS OF THE RADIO STATION

Cadena3 is a private radio station that broadcast from the city of Cordoba to all Argentina using their big affiliated network. Cadena3 is the successor of LV3 Radio Cordoba, public broadcaster founded in 1930 with the name of LV3 Radio Aires-Córdoba. Cadena3 adds to the historical frequency of LV3 (700 kHz AM for the province of Cordoba and south of Santa Fe) several new affiliated in the rest of the country, and today is ranked third of the most listened radio stations during the mornings (in Cordoba around 85 % of the audience follows Cadena3).

In 1992 AEQ equipped completely Cadena3 using the latest analogical technology available in these days with seems excellent results, because most of the original material has survived ONAIR operatively to the present day.

Recently technical direction of the company has decided to renew their central studios facilities to digital and has obviously chosen AEQ as main contractor, on the base of AEQ digital technology BC2000D. The totality of the project equips new 3 ONAIR radio studios, one new central control room (MCR) and a complete multi-conference systems.

Three radio studios have been created over AEQ ARENA digital audio mixers with 25 motorized faders control surface and redundant power supply, offering 28 analogical inputs/outputs, 8 digital AES inputs/outputs, and 16 microphones. AEQ to simplify the final installation and to reduce wiring work, time and cost, prepared several complete cabling kits specifics for each studio, as well as AEQ RC01 generic connection points of studio headphones and microphones.

Cadena3 Master Control Room has been designed over AEQ BC2000D digital central router that includes 56 analogical in/out and 16 digital AES in/out (in the future max size is 1024x1024). All the radio audio signals in the central facilities of Cadena3 are managed by this new central digital router, so AEQ equipped this system as 100 % redundant including double control modules in all the nodes, double power supplies for all the chassis and numerous DSP for backup. Control of the router AEQ BC2000D is decentralized from PC distributed in the diverse radio studios, as well as from 4 dedicated XY panels AEQ NCB100 for quick-operations, always controlled by passwords, associated with different users profiles and their proper limited access levels.

The totality of the connections between new digital ONAIR radio studios and the central control router have been designed using MADI (AES10) links over dedicated optical fibers, allowing each of them to transport up to 64 independent audio channels (with digital AES3 quality): so whatever of the audio signals generated by Cadena 3 in any of the studios can be sent for analysis, operation, processing or distribution to practically any place/room/studio of this central facilities building.

AEQ installs together with the new central router a multi-conference system AEQ SYSTEL600 to manage all the telephonic calls of the radio station. This multi-conference system in the configuration of Cadena3 supports 20 digital independent telephone hybrids for up to 20 simultaneous ONAIR calls, that it is possible to distribute and share in real time between the diverse radio studios of the installation, over the MADI links without need of any additional cabling. Two touch-screen PCs and 8 hardware-based AEQ SYSTELSET units (for journalists and producers) control SYSTEL600.

This ambitious project has been coordinated by Cadena3-Argentina Technical Managers Mr. Axel Maldonado and  Mr. Emilio Martin, who in collaboration with the technical services of AEQ-Madrid and the technical staff displaced to Cordoba, led the tasks of installation, configuration and start-up of these complete digital supplied material and systems.
