 Solution Configuration List + System Diagram

  Solution Configuration

• Audio pickup section: True diversity wireless handheld microphones are selected to ensure clear communication for leaders’ speeches. To prevent issues such as signal dropouts and interference, an antenna amplification system is also incorporated.

• Control section: A digital mixing console, digital audio matrix, and feedback suppressor are utilized to manage the entire system, delivering clear, distortion-free sound without feedback and whistling. The system also offers various sound effects processing functions to further enhance the audio experience.

• Sound reproduction system: Highly directional dual 10” linear arrays are employed for distributed sound amplification. These arrays not only provide high sound pressure levels but also allow vertical angle adjustments based on the listening area. Each set is paired with a single 18” subwoofer to compensate for the lower limits of mid-bass frequencies. Additionally, four stage monitor speakers and four lip speakers are provided to fill sound gaps for the stage and front-row audience. Two floor-standing subwoofers offer extra low-frequency energy, improve low-frequency response and enhance the depth of the sound quality, creating a more refined audio experience. 250W constant impedance speakers are used to reinforce sound in the center area, ensuring even sound pressure distribution and fulfilling both aesthetic and functional requirements of the auditorium.

• System protection: To ensure the safety and reliability of the system, especially in the event of unexpected situations, a power sequence controller and purification system are used to protect the equipment from potential damage.
