1. Using the computer aided acoustics design, the sound expansion effect of the system after installation can be accurately calculated, and the system has high feasibility and avoids blind design.

2. The acoustical design specification requires that the acoustical quality of the audience area is mainly sound pressure level, the language is clear, the comprehensible degree is high, the second is the fullness, the proper loudness and uniformity of each place, the acoustic defects such as echo and sound focusing in any position of the audience area, and no interference from the noise of the audience area equipment and the ambient ambient noise. These indicators form a comprehensive effect of outdoor sound reinforcement design.

3. select the best sound box of linear array system, have multiple control and protection functions, ensure the key part of the system; use digital audio control and processing, computer debugging, can pre store various use modes (such as performance mode, music mode, competition mode, etc.); configure a variety of signal records and playback sources (DVD Player, MD recorder, with high digitization, good sound quality, long recording time and easy storage. Multi mode systems are compatible with each other, flexible in function conversion and saving in capital.
