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.
