All commentary positions at the Pan American Games, with AEQ

International Sport Broadcasting, as the company responsible for the entire television and radio technical service at the event, used the AEQ DCS-10 commentator position system to transmit the signal to the entire world.

International Sport Broadcasting, as the company responsible for the entire television and radio technical service at the event, selected the commentary system for the Pan American Games held from October 14 to 30 in Gualadalara (Mexico). AEQ DCS10 due to its more than proven experience in this type of events, where given its importance, factors such as performance and reliability take precedence.
Furthermore, the Pan American Games are held at several venues, in some cases quite far from each other, so after consulting with the national telecommunications operator, it was decided to interconnect all the venues over E1/T1 links, also using the AEQ RANGER multiplexers.

AEQ has installed 60 AEQ DCS-10 model commentator positions with their corresponding centralized control system to capture the audio signals from each commentator present at the event.

The Digital Commentator Unit (CU) is a digital mixer designed for radio and television commentators, which includes all the features necessary to adequately cover remote program broadcasts at major sporting events. Each CU can be used by up to three commentators and one guest. It includes a system for easy communication with the technician and with its own remote studio, as well as micro-headset monitoring: the listening circuits allow each commentator to select and mix the signals of the Public Address System (PA), International Sound (IS), external lines (AUX and GUIDE) and the Program signal in the right and left ear.

Commentator Control Unit

On the other hand, the Commentator Control Unit (CCU) is the heart of the system, being designed to control and monitor up to 10 CUs, and supply the required remote power. Thanks to the centralized design of the DCS-10 system, installation times and preconfiguration work are radically reduced. The CCU includes up to 10 control Modules, a Monitoring and Intercom Module, and two independent power supplies. Each Control Module is associated with a CU, controlling the input and output signals and their routing, using signal processing and digital automation in real time, through different sections.

To interconnect the different headquarters with the International Broadcasting Center as the nerve center of operations, 22 AEQ RANGER model E1/T1 multiplexers have been used. It is a multiplexer of encoded audio and data channels with E1 (2,048Mbps) and T1 (1,544 Mbps) access. It allows you to work with encoded audio qualities of 3.5 kHz, 7.5 kHz, and 15 kHz bandwidth, and with data channels of 256 Kbps, 128 Kbps, and 64 Kbps bandwidth. Connected to an E1 type access (32 64 Kbps slots) it can use 31 64 Kbps slots for audio and data transmission, and the remaining 64 Kbps channel for synchronization, and when connected to a T1 type access it can use 24 64 Kbit slots.

The Ranger equipment is built on a standard 19-inch x 6 U high rack with a depth of 360 mm and has space for 8 audio and data I/O modules, 1 control module and 2 power supply modules.
