PGA-1025 Application Field and Working Principle

PGA-1025 is a dual active bridge (DAB) power amplifier from Marubox. It is a digital power amplifier designed for a wide range of applications, including PA systems, home audio systems, studio monitors, car audio systems, and professional sound installation. It is easy to use, efficient, and provide high fidelity sound with low distortion. It is also highly reliable and able to provide stable power output over a wide temperature range.

PGA-1025 is a two-channel, Class D amplifier that can provide up to 1000 watts of power output. It has an integrated DC-DC converter that allows for both asymmetric and symmetric power supply. Asymmetric supplies offer better efficiency and a lower noise floor than symmetric supplies, while symmetrical supplies offer better linearity and dynamic range. It also supports both balanced and unbalanced inputs and a wide range of gain settings. It has a wide operating temperature range of -40 ℃ to +85℃, making it ideal for use in cars, boats, and other harsh environment applications.

The working principle of the PGA-1025 is fairly straightforward. It uses an efficient, low noise, low-dropout, high-efficiency switching power stage coupled with a sophisticated algorithm to control the output of the two amplifiers simultaneously. The amplifier is designed to provide consistent and reliable power with both AC and DC inputs. It also provides a wide range of configurable options such as gain and crossover frequencies, enabling it to match various speaker and system configurations.

The PGA-1025 is designed to be easy to use and can be quickly configured by a user for various applications. Set-up is straightforward and all relevant parameters can be easily adjusted via a simple to use LCD interface. The unit can be set up for use either as a stand-alone or as part of a larger system and is also suited for mobile applications.

Due to its unique feature set and ability to handle high power output, the PGA-1025 is an excellent choice for a wide range of applications, from PA systems to car audio systems to professional sound systems. Its wide range of gain settings and configurable options make it easy to adjust the sound quality to the desired level. As such, it is an ideal choice to use in applications that require high fidelity sound reproduction with low distortion.
