1. Reverberator

A very important part of the stage sound system and large-scale stage lighting concert hall is the reverberation processing of the vocals. After the reverberation processing of human singing, it can produce a sense of beauty of electronic sound, making the singing voice have a special charm. It can mask certain defects in the voice of some amateur singers, such as hoarseness, guttural sounds, and shrill vocal cord murmurs, through reverberation processing to make the sound less difficult to hear. In addition, the reverberation sound can also compensate for the lack of overtones in the timbre structure of amateur singers due to the lack of special vocal training. This is very important for the effect of stage lighting concerts.

2. Frequency divider

The circuit or device that implements the frequency division is called a frequency divider. There are many types of dividers, and there are two types: sinusoidal and pulse dividers according to the waveform of their crossover signals. Its basic function is to divide the full-band audio signal into different frequency bands according to the requirements of the combined speaker, so that the speaker unit can get the excitation signal of the appropriate frequency band and work in the best state.

3. Pitch changer

Because people's voice conditions are different, the tonal requirements for accompanying music when singing are also inconsistent, some people want to be lower, others need to be higher. In this way, it is required that the tone of the accompanying music should be adapted to the requirements of the singer, otherwise the singing voice and the accompaniment will feel very discordant. If an accompaniment tape is used, a pitch changer is required for pitch shifting.

4. Limiter

It is a collective term for the combination of compressors and limiters. Its main role is to protect amplifiers and speakers (speakers) and create special sound effects.

5. Effects

Sound equipment that provides sound field effects, including reverb, time delay, echo, and special treatment of sound.

6. Equalizer

It is a device that raises and attenuates different frequencies and adjusts the ratio of bass, midrange, and treble.
