3.Key Points for System Connection and Commissioning
(1) System Connection Topology
1)Sound pickup equipment (wireless microphones, wired microphones) is connected to the digital mixing console via audio cables, and the output signal of the console is sent to the digital audio processor.
2)The digital audio processor distributes signals to the corresponding power amplifiers according to the preset crossover scheme, and the amplifier outputs are connected to the corresponding loudspeaker devices.
3)All equipment is powered uniformly through the power sequencer to ensure a standardized power-on sequence. The digital audio processor and the mixing console realize data interaction and control via network interfaces.
(2) Core Commissioning Points
1)Sound field coverage commissioning
Use the delay function of the audio processor to adjust the signal delay time of main loudspeakers and auxiliary loudspeakers to ensure uniform sound field coverage without phase interference.
Use a spectrum analyzer to measure the sound pressure level in different areas of the theater, ensuring the difference is controlled within ±3 dB, meeting the requirements of GB/T 28049-2011 Code for Design of Sound Systems in Auditoriums and Stadiums.
2)Sound quality optimization commissioning
According to the theater’s acoustic environment, adjust equalization parameters through the mixing console and audio processor to suppress resonant frequencies and improve speech intelligibility and music reproduction. Preset multiple groups of effect parameters for different performance types for quick switching.
3)System stability test
Carry out long-time continuous operation tests to check equipment heating and signal stability. Simulate sudden power failure to test the protection function of the power sequencer and parameter recovery after restart, ensuring stable system operation under various conditions.
