Why set a compressor in the KTV pre-effector?
As we all know, there are full-range speakers in the audio system, and the full-range speakers are equipped with tweeters and woofers. If the speakers in the speakers are not used carefully, they are more prone to damage.
Generally speaking, if the signal from the signal source (such as a microphone) is too large, it may cause high-frequency harmonic distortion in the internal circuit of the front-end device, which directly threatens the safety of the tweeter in the speaker.
If the signal output from the front-end equipment to the power amplifier is too large, it is easy to cause overload distortion of the amplifier, which directly threatens the safety of the woofer in the speaker.
The general audio system is equipped with a tuner for on-site operation control. The tuner will always monitor the size of the input and output signals of the mixer, and make corresponding adjustments. Through manual intervention, the input or output signal is prevented from being too large. Avoid burning the speakers.
Generally speaking, the audio system used for KTV is an unmanned control system. In this case, if the input or output signal of the pre-effector is too large, it is easy to threaten the safety of the speakers in the speaker.
Therefore, the KTV pre-effectors currently on the market are equipped with a compressor function, which is used to prevent the input signal from being too large or the output signal from being distorted, and the purpose is to avoid the phenomenon of burning the speakers in the speaker.

The microphone input channel and each output channel of the KTV pre-effector are equipped with the function of compressor, and their uses are different.

Among them, the compressor configured in the microphone input channel, after being correctly set, can automatically compress or limit the signal when the microphone signal is abnormally large (such as shouting, singing and roaring). Control the dangerous super large signal within a safe range, so as to prevent the high-frequency harmonic distortion of the pre-effector's own circuit, which is beneficial to protect the safety of the tweeter in the speaker.
The compressors configured in the main output, bass output, rear output and other output channels of the pre-effector are mainly used to control the size of the signal output from the pre-effector to the power amplifier.

Through the correct settings, the signal output from the pre-effector to the power amplifier can be prevented from being too large, so as to avoid the overload distortion of the power amplifier, thereby avoiding the phenomenon of burning the woofer in the speaker.
Therefore, for the driverless audio system in KTV, it is very important to correctly set the microphone input channel and the compressor in each output channel if you want to prevent the burning of the speakers!
