Under the limited budget, Super Light Technology Co Ltd. still kept up with high standards to achieve listening needs for 80% of the site.

The main goal of this improvement was to solve two issues of voice transmission:

1. The time delay and the non-uniform sound pressure distribution
2. The frequency interference of wireless microphone by 4G mobile phone

Due to outdoor or half outdoor installation, all the speakers are designed according to IP54 standards, including mounts, switch junction boxes and other accessories. The powder coating paint on the surface is specified to resist severe weather conditions.

The loudspeakers used for the average distribution installation with the same direction are mainly the Pan Speaker passive column speakers. Each region can be controlled  independently and completely overcomes the audio time delay problem. The sound pressure distribution level is superior to the original goal. The listening distance of 10 meters for audience comes to 90 dB SPL standard, even over 95 dB SPL.

After completion, the owner participated in the full test of sound field and system operation. In comparision to the previous installation, the final results greatly satisfy all, therefore, the acceptance work passed at one time.
