Tips for Public Address System Installation

The public address system belongs to a branch of the amplifying sound system, and the amplifying sound system, also known as the professional sound system, involves the edge sciences of three disciplines: electroacoustics, sound construction and music. Therefore, the final effect of the public address system involves a reasonable and correct electro-acoustic system design and debugging, a good sound propagation environment (building sound conditions) and accurate on-site tuning are the best combination of them, and this three complement are indispensable.


As a system, public broadcasting must comprehensively consider the influence of various factors on it. Therefore, on the basis of selecting high-performance electroacoustic equipment, careful system design and debugging, good sound building conditions can be used to achieve pleasant and natural sound effects. Here are some tips for installing the digital public address system to share with you:


1. Transmission methodThe output power feeding method of the system adopts the cable broadcasting transmission method.

2. Requirements for line attenuationIn the public address system, the line attenuation from the output of the power amplifier equipment to the farthest user speaker on the line should meet the following requirements:Business broadcast should not be greater than 2 decibels (at 1kHz)Service broadcast should not be greater than 1 decibel (at 1kHz) The feeder circuit with constant voltage output is adopted, and the output voltage is 70V or 100V.
