Holophone H2-PRO's were used for the broadcast of the 131st Kentucky Derby from Churchhill Downs in Lousiville, KY with NBC Sports. The Main Ambience Holophone mic was hung underneath the balcony where the main Hi-Def cameras were placed at the finish line, high up in the stands with the "nose" of the H2-PRO pointing toward the track, to provide a realistic and three-dimensional ambience to the overall Surround mix that worked with the perspective of the Hi-Def picture and was broadcast via Dolby Pro-Logic II to viewers everywhere.
