Does your public address audio system have any noise?

In the application of broadcast systems, having noise in the audio system is a common issue. However, troubleshooting and resolving the problem may take some time, especially if it involves post-sales support. If the supplier is not local, post-sales support can be even more challenging. Can we learn to identify and address the issue ourselves?

SPON Communication explained to us how to step by step inspect and analyze the nodes where the noise occurs, as well as the corresponding solutions for each stage.

This is the link to the article：https://sponcomm.com/info-detail/common-issue-in-public-address-system---noise-in-speakers

SPON listed three reasons for us, providing specific inspection methods and solutions for each reason.

1. Linear Input Signal Source

2. Microphone Input Signal Source

3. Power Amplifier or Preamplifier

Distinguishing Between Constant Impedance and Constant Voltage in Broadcast Systems

Reposted from: https://sponcomm.com/info-detail/distinguishing-between-constant-impedance-and-constant-voltage-in-public-addressing-systems How to Choose Amplifiers and Speakers for Public Address Systems? What Are the Differences Between Constant Voltage and Constant Impedance Amplifiers?   Constant Voltage Power Amplifier Commonly employed in public settings. Monaural output. High voltage, low current output.   Constant Impedance Power Amplifier Commonly employed in public settings. Monaural output. High voltage, low current output.   Constant voltage systems are used in large spaces where high audio quality is not a primary concern. Conversely, constant impedance systems, due to transmission limitations, are typically employed in smaller spaces where sound quality is a more critical factor. Generally, constant voltage outputs are used in public address systems, while constant impedance outputs are preferred for audio systems.
