• Indiana State Fairgrounds Coliseum

  • The fairgrounds coliseum is an indoor multi-use arena, located on the Indiana State Fairgrounds in Indianapolis, Ind. The building was originally opened in 1939 and has undergone an extensive renovation that was recently completed in April of 2014. This project included the addition of a youth arena on the south side of the main Coliseum building providing two venue options. ESCO Communications was the low voltage contractor for a completely new audio system, broadcast cable infrastructure and CATV distribution system.

    The coliseum audio system features a 32-channel console at the sound booth on the east end of the concourse level, and a 16-channel console for video feeds in the control room on the upper concourse level. Audio control and signal processing is completely digital via a main PC and a portable laptop. The digital audio equipment operates on a dedicated network for dependable communications. A distributed speaker system provides complete coverage of the seating and floor areas while corridors and common areas are served by independent systems for flexibility. Due to the variety of uses of the facility, an extensive network of audio junction boxes provides flexible input options to a main sound room on the event level. From there, any source can be patched into the system.

    The arena audio system has the same key features as the coliseum system such as digital control, distributed speakers and audio junction boxes for inputs. It also has over-head microphone jacks in the center of the arena. All systems have basic control from the adjacent skate shop when the main coliseum is not in use.

    The broadcast cable system includes strategically placed television junction boxes with fiber that runs back to the video control room. This allows for cameras that are placed around the facility to easily send video feeds to the main system for distribution.

    The CATV system provides the option to send a wide range of channels to more than 72 flat-screen TVs throughout the facility. The head end includes eight, four-channel modulators to convert media sources to RF for distribution. The signal is sent from the head end to four distribution rooms via fiber where it is converted to coaxial cable for the final run to the TVs.
