Audio Tuning Essentials！Audio brand ktv

　　① The tuner (www.gae-pro.com) should monitor the left and right channels separately. Should be familiar with the relationship between monitor sound and live sound, which largely depends on personal hearing.

　　②Use reverb to beautify the singing voice. For non-professional singers, the reverberation should be properly accentuated to cover up noise and defects in vocalization.

　　③ When the volume is small, pay attention to increase the low frequency and high frequency; when the volume is high, increase the intermediate frequency appropriately to enhance the brightness of the sound.

　　④ Tuning is mainly based on singing. Before the vocals appear, gradually lower the accompaniment to accentuate the vocals.

　　⑤ Pay attention to disco or rock music: when boosting the bass, do not turn the compensation knob violently, so as not to damage the amplifier and speakers due to excessive power output.

　　⑥If there is an acoustic feedback whistling sound, you should quickly reduce the total volume of the microphone (or fine-tune the knob) to remove the whistling sound, and then gradually increase it after finding out the cause.

　　1. The human voice is a compound sound. That is, it consists of the fundamental tone of the sound and a series of overtones. These overtones are the digits of the fundamental frequency (www.gae-pro.com), which are called partials in physics, harmonics in electroacoustics, and overtones in music. If the amplitude of low frequency overtones is strong, the timbre will be thick; if the amplitude of mid-frequency overtones is relatively strong, the timbre will be round, natural and harmonious; if the amplitude of high frequency overtones is relatively strong, the timbre will be bright, clear and analytical. powerful.

　　2. If the high-frequency frequency is too weak, the tone will become dull, lacking in charm and personality; if the high-frequency frequency is too strong, the tone will become shrill and harsh.

　　If the frequencies in the mid-to-high range are too weak, the timbre will become dull and hazy; if the frequencies in the mid-to-high range are too strong, the timbre will become dull.

　　3. If the low frequency frequency is too weak, the sound will become thin and pale; if the low frequency frequency is too strong, the sound will become muddy.
