Advantages of Digital Public Address Amplifiers

Digital public address amplifier is also called class D audio power amplifier. By controlling the on / off of the switch unit, the amplifier that drives the speaker is called a Class D amplifier. In recent years, it has gradually become popular. Although it has been out for many years, it still has the characteristics of high efficiency and small size compared with the general linear class AB power amplifier circuit.

Advantages of digital public address amplifier:

1. Digital public address amplifier has high energy conversion rate, and its small volume makes it highly reliable. The battery utilization rate of digital public address amplifier can reach more than 90%, which meets the requirements of environmental protection.

2. Digital public address amplifier has a wide range of applications, and its minimum load impedance can reach very low. In addition, no matter how the load impedance changes, the battery conversion rate is basically unchanged

3. Digital public address amplifier has no relative changes of high frequency, intermediate frequency and low frequency. Its sound is very clear, and the sound image has a very accurate positioning.

4. Digital public address amplifier are very suitable for mass production of products. As long as the installation of the components is ensured, the product can have a good consistency. The production process does not need any debugging, safe and reliable.

5. Digital public address amplifier can directly realize group control, remote control, monitoring and other functions without adding any devices.
