【 Weak current College 】 KTV room audio system tuning techniques

1. adjust the sound quality and volume. Due to the KTV singing karaoke, no trained person's voice, the sound quality isn't very good but lack of brightness, men prone guttural and Husky, girls prone to breath noise and fault code. Therefore, the need for high-frequency 500MHz above, on the low-frequency 100Hz following also need to be removed, at the same time in the band promotion 3-6dB to increase luminance, the sound is clear and bright. General singer voice is low and the lack of loudness, volume to increase the number and frequency of the 2000MHz nearby paragraph be promoted so that treatment can increase the sound loudness.
2. adjust the sound volume with the accompaniment of microphone volume. In General, a good amount of songs, you are assigned, the accompanying music is roughly 40%, 60% of the singing voice. If the singer on the song melody is not familiar, easy to sing out of tune, or not taken on, then appropriately increase the number of accompaniment of the volume.
3. use reverb beautification. KTV song characteristics, is in the song plus electronic reverb, can cover up the throat sound and defect in some of the sound. Male vocal, generally low to reduce reverberation time shorter, and soprano singing time may be appropriate to extend the reverberation time in order to increase the sound of color. As for singing with regard to the environment, if the room surrounding wall is made of wooden planks, itself a reverb effect, then you should adjust the reverb time, so as to avoid short some obscure; in sound without special requirements, you can adjust the reverb knob in the middle position, which is a direct sound component and the proportion of reverberation component of roughly 1: 1.
4.KTV rooms sound tuning of Whistler. High-frequency if you are prone to howl? it's not a tuning is not in place is decorated with more obvious defect of acoustical or both. Then you can try the microphone bass, treble attenuation due to maintain the 12 o'clock position or right ascension, and then--slow-slow-to-increase microphone volume begins with high frequency whistle appears and then the appropriate callback is to secure the volume location. Attention to two microphones at the opening of the FBI, at least one shall be placed on the table to the speakers. Believe should be performed easily sound clear and relatively safe microphone effect (provided that the complete device including the microphone has a flat frequency response, actually means to have a better quality. If the hardware is natural enough won't bother. Device to change again).
