Osseo High School had an older gymnasium system that was no longer giving them all the features and sound quality they needed for their events. They asked us to give them a phased approach to the system, so they could upgrade the pieces as budget allowed. The first phase upgraded the microphones and main equipment, while the second and third phases upgraded the speakers. They were able to do both phase one and two as part of the initial installation.
We chose a combination of Sennheiser EW series handheld and beltpack wireless microphones to give them the most flexibility for both presentations and sports announcements. We also included a headworn mic for a gym instructor if they need to use it for classes.
The main processor is a Biamp Nexia with a Red-1 controller in a portable setup:
They have a plug-in at the front of the bleacher by the announcer position as well as back at the rack for classroom and presentation use.
The existing speaker system was 2 speakers along the middle of the room, which provided adequate coverage on the main floor, but not much sound on the bleachers. We added a line of 5 speakers on either side of the gym floor to cover both bleacher sections.
A large Crown amplifier provides individual power to each side of the room, so the speakers may be turned on / off if only one section of bleachers is used.
To comply with ADA regulations, a wireless RF-style hearing assistance system was also installed for the room.
The final phase will be to replace the floor speakers with the same model speaker as the bleacher speakers, to give even and consistent coverage throughout the space.
