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 IPxx standards, including mounts, switch junction boxes and other accessories. The specification is stainless steel AISI304 with powder coating paint on surface for resisting more severe weather conditions.

The loudspeakers used the average distribution installation with same direction, mainly selects the PAN SPEAKER passive column speakers. Each region can independently control the level, 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. To compare to the previous prospective, the final installation results greatly satisfies them, therefore, the acceptance work passed at one time.
