The School Division is seeking proposals for the supply, installation, configuration, and support of a digital Classroom Audio Enhancement System designed to improve speech intelligibility, classroom communication, accessibility, and multimedia audio distribution within instructional environments. The proposed solution shall provide effective audio coverage for classrooms up to 300 m² (3230 ft²) and deliver consistent sound distribution throughout the instructional space while minimizing dead zones and uneven audio coverage. The system shall be optimized for educational speech intelligibility, supporting a speech audio bandwidth of at least 200 Hz – 7.5 kHz, and shall reduce teacher vocal strain through clear and even voice reinforcement. The speaker system shall include integrated distributed loudspeaker technology or equivalent with a minimum amplifier output of 80 watts and a multi-speaker array designed for classroom acoustics and controlled sound dispersion. The system shall utilize license-free wireless technology operating in the 2.4 GHz spectrum or equivalent and include adaptive automatic frequency hopping or similar interference mitigation technology suitable for high-density wireless school environments. The wireless microphone system shall provide a minimum operating range of 25 meters (82 feet), support educational wireless microphones, and allow simultaneous operation of multiple classroom systems within the same facility. The solution shall include integrated Bluetooth audio capability supporting Bluetooth version 4.2 or newer, along with auxiliary audio input and output connections, including a minimum 3.5 mm input and line-level output or equivalent. The system shall support multimedia audio playback with an audio bandwidth of at least 100 Hz – 20 kHz and provide independent voice and multimedia volume controls accessible to classroom staff.
