What are the installation procedures of power amplifier?

The power amplifier is usually installed on the left or right side of the luggage compartment or on the seat partition between the luggage compartment and the cockpit. When the power amplifier is fixed, make sure that the front of the power amplifier is facing up, and at the same time, the installation position of the power amplifier should keep a distance of 60mm from other objects around it, which is convenient for heat dissipation. If it is necessary to make a mounting bracket or mounting box for the power amplifier, the power amplifier should be far away from the woofer. Connect the RCA audio output line, grounding line,+12V power line, splitter, fuse and speaker output line between the power amplifier and the host. Amplify the volume: The main function of power amplifier is to amplify the volume, which is generally used in home audio and various audio equipment. The installation of the power amplifier is also relatively simple. Many audio equipment will carry some amplifiers, but some people will install one themselves because they can't meet the demand.

Improve the sound quality: Power amplifier can not only amplify the volume, but also improve the sound quality. However, it should be noted that only when the power amplifier is installed correctly can the sound quality of our sound system be effectively improved. Used in military field: A very important function of power amplifier is to be used in military field, mainly to amplify the captured signal. Because the sound signal we captured is very small, it is difficult to get effective information. At this time, we can use a power amplifier to amplify the signal. The efficiency of power amplifier, the essence of power series amplification is to convert the DC power provided by power supply to the amplifier into AC power on the load through the control of transistors. The higher the efficiency, the better the performance of the power amplifier. Under the condition of large signal operation, the operating point of the transistor will swing up and down greatly. Three working states, the power amplifier is divided into Class A, Class B and Class A and B according to the different working states.
