What is a power booster? Uses of power amplifiers in sound

The power amplifier is a device that amplifies the audio signal through the speakers before reaching the listener’s ears, helping to amplify and push the power of the entire sound system up to the level that meets and needs the user.

Using a power amplifier will reduce speaker distortion, the sound when singing is softer, limiting the risk of damage to speakers and devices such as amplifiers and microphones. The connection between the speaker and the appropriate power amplifier will help your system operate stably and optimally.

Outstanding features of the audio power amplifier

The power amplifier can replace the entire amp because it can load 1 to 2 pairs of high-powered speakers, serving professional sound for large room karaoke, bars, and stages.

Deciding almost half of the sound quality of the system, the sound signal is far, clear, gentle and more realistic.

The signal is transmitted stably, without interference, the structure is solid, the jack ensures a safe connection.

Structure of power pusher

The basic structure of the power booster includes

The case helps to protect the internal components well, so it is designed from high-grade metal with high rigidity and durability. The heat dissipation slots on the case balance the device temperature so that when operating continuously, it will not affect the life, overload, or cause damage.

The body consists of electronic components, accessories and small boards, this is also the part that determines the quality of the power amplifier.

Power transformer is a device that transfers energy between 2 or more circuits through electromagnetic induction. Power transformers are used to increase or decrease AC voltage.

The power circuit has the function of receiving the input audio signal, amplifying the power, and producing more powerful sound.

The power clamshell is the semiconductor part combined with the IC, affecting the power level of the pusher.

Fan to ensure continuous operation of the device without affecting machine life, most power amplifiers have 2 radiator fans to cool the internal components located at the back.

When to use a power booster?

For speakers with high sensitivity and impedance, you only need to use a low-power amplifier , whereas speakers with low sensitivity and impedance (about 4 Ohm, low sensitivity below 90dB) need a large-capacity amplifier. for quality sound.

The sound system has a large capacity, the theater space is large and there are sound-absorbing devices (sound-absorbing wall foam, soundproof fabric curtains) that will produce a more realistic and quality sound.

For light music such as lyrical, ballad, you only need to use a small power amp. As for strong music like rock, R&B, you need to use a larger capacity amp to have good sound quality.

Some notes when using audio power amplifiers

Put the power booster in a dry place , avoid water, fire, do not place heavy objects on the power booster to affect the board.

Turn off the power of the pusher before connecting to devices such as speakers, amps.

The ground wire in the power amplifier’s board must be grounded.

The power supply for the entire sound system must be large, the wires must be of good quality to avoid unstable voltage and damage to the equipment.

Turn the volume to 0 before turning on the power booster, wait for about 5 to 10 minutes, then turn up the volume, do not leave the volume at the highest level.
