Precautions when using the amplifier

Problems to pay attention to when using the amplifier 1. Many sound engineers know that the amplifier power is too high and will burn the speaker, but they do not know that the amplifier power is too small, it is easier to burn the speaker, because when the small power amplifier is working at full load, it is easy to form distortion and distortion. After forming a square wave, an abnormal current is generated, which can easily burn the horn.

Common Problems and Solutions of Mixer

Mixing console is an important tuning equipment. It is widely used in video recording and sound reinforcement systems and plays an important role, improving the sound quality and live effects. However, in actual operation, if you do not have certain relevant knowledge, it is quite difficult to operate. At the same time, the sound quality effect is often unsatisfactory. Therefore, in order to improve the output of the mixer, it is important to learn and understand the knowledge of the demodulator.

How horn sound works

A horn is a device that converts electrical signals into acoustic signals. It consists of coils, magnets, and paper cones. The amplifier outputs an electric current of different size (alternating current), which moves the coil under the action of the magnetic field through the coil. The coil is connected to the paper cone to drive the paper cone to vibrate, and the vibration of the paper cone drives the air to make a sound
