User Report: AEQ Again Furnishes Cadena3
Argentina — Cadena3 is a private radio station that broadcasts from
the city of Cordoba to all Argentina through a network of affiliates.
It is the successor of LV3 Radio Cordoba, a public broadcaster
founded in 1930 with the name of LV3 Radio Aires-Córdoba(AM).
Cadena3 adds to the 700 kHz historical frequency of LV3 in the
province of Cordoba and south of Santa Fe with several new affiliates
in the rest of the country. Today it is ranked third during the
broadcast equipment manufacturer AEQ completely equipped Cadena3 with
the latest in analog broadcast technology. Thanks to the quality of
the equipment, much of it is still in use today.
have changed and we must change with them. We in broadcast
engineering management have decided to refurbish our central studios
facilities with digital technology. Once again we have chosen to go
with AEQ as the main supplier. The centerpiece of the project will be
the AEQ BC-2000 D multiplex router.
the project involves outfitting three on-air radio studios, one new
master control room and a complete broadcast phone system.
radio studios have been equipped with AEQ Arena digital audio mixers.
They are outfitted with 25 motorized faders, 28 analog
inputs/outputs, eight digital AES inputs/outputs, 16 microphone
inputs and a redundant power supply. To reduce wiring work, time and
cost, AEQ prepared several complete cabling kits — each specific to
a studio — as well as AEQ RC01 studio headphones and microphone
the Cadena3 master control room has been designed around an AEQ
BC-2000 D digital central router. It offers 56 analog ins/outs and 16
digital AES ins/outs with a maximum size of 1,024 x 1,024. All the
radio and audio signals in the central Cadena3 facility are managed
by this new digital router, so AEQ equipped it with 100 percent
redundancy, including dual control modules in the nodes, dual power
supplies for all the chassis and numerous DSP processing modules for
BC-2000 D is controllable through any PC on its network as well as
from four AEQ NCB-100 rack-mounted hardware controllers. This system
offers various user profiles and access can be limited to certain
access levels and passwords can keep unauthorized users out.
interconnections between the central controller and the on-air
studios uses MADI (AES10) links over dedicated optical fiber,
allowing transport of up to 64 independent audio channels with
digital AES3 quality. Any signal generated in any of the studios can
be sent for analysis, operation, processing or distribution to
practically any place/room/studio in the Cadena3 facilities building.
addition, we had AEQ install an AEQ Systel600 phone system to manage
telephone calls for broadcast use. For Cadena3, this phone system
supports 20 digital independent telephone hybrids for up to 20
simultaneous on-air calls. These can be distributed and shared in
real time between the various radio studios of the installation and
over the MADI links without need of any additional cabling. Two
touchscreen PCs and eight hardware-based AEQ SystelSet controllers
for journalists and producers to control the Systel600.
