Asthe main operating content of KTV, the sound effect it created hasbecome a product with the KTV private room environment, services,drinks, etc., and become KTV operators and KTV audio equipmentproduction plants, sellers, engineers and DJs. Focus. Therefore, theproduct is because the KTV audio effect is developing frompersonality to common. We know that the sound effect is described bycharacteristics, and we cannot simply use or not. The contentreflected in the sound is often straightforward, specific andobjective, but the sound quality and sound color are extremelyabstract, subjective and difficult to communicate. Today, I willintroduce a few keywords for sound quality judgments.
1.Clear and turbidity
Thesound of the excellent audio system is clear and the frequencyresponse is wide and uniform; especially the medium and highfrequencies have density, the reverberation is appropriate, which canbetter distinguish the sound and location of the instrument.Conversely, it is called turbid.
2.Round and hair
YuanRun actually refers to distortion, especially the very smalldistortion of the medium and high frequencies. Its hearing is happy,pleasant, the bass is not turbid, the middle sound is not hard, andthe treble is not ears. The hair and roundness are opposite, whichmainly manifested as a rough and visible distortion of sound hearing.If there is 5%distortion in the sound, the average person feels hair,and professionals can listen to 3%.
3.Plum and dry
Thesound is thick, the loudness is strong, the medium and high frequencysense is good, the reverberation is sufficient, and the transientresponse is full; otherwise, it is dry.
4.Brightness and gloom
Brightnessmeans that on the basis of the high, medium and bass balance in theentire sound domain, the medium and high sounds are slightlyprominent and have a rich homophonic, with moderate sounds and smalldistortion. Darkness refers to a serious lack of mid -tone, loosebass, and poor analysis.
5.Wide and thin
Thewide sound audio response, bright treble, sufficient bass; thinsounds often look pale and lack bass or treble.
6.Dry and wet
Mainlyrefers to the effect of reverberation. Short reverberation time andinsufficient depth are dry; excessive reverberation, the soundentanglement is not clear. The wetness of the sound is sometimesdetermined by the software and can be caused by the listeningenvironment.
7.Live sense
Thesound is bright and spreading well, and there are certain sounds,especially the effects of 800 ~ 5000Hz, the effect of the concerthall closest to the concert hall, is called a good sense of scene.
8.A sense of balance
Thefrequency range is wide, especially the frequency of each unit of thesound box is smooth and non -uneven. The whole sound is fused andwide, and it sounds relaxed and happy. It is called a balance.
9.Cold and warm
Thereare greater individual differences in the warmth of the sound. Thecold sound is very small and very balanced, and the equipment hasgood physical indicators. The warm voice is based on the soundbalance and the less straightforwardness, and it has some rounded andplump personality. Generally, the sound of the transistor amplifieris colder, and the electronic tube has a charming warm color. Thecoldness and warmth of the sound are not derogatory words. Whichsound of the preference varies from person to person.
Inaddition to the above, the judgment of the sound quality may be moredue to personal feelings and also affected by other objectivefactors.
Thereis a big difference between KTV audio and stage audio, home audio,and fever audio: a KTV audio in a designated area must be maximizedby the target consumer group, and it is necessary KTV audio designersand investors make rational decisions and cannot completely copy theso -called successful experience.
TheKTV audio effect design includes several aspects of audio equipmentconfiguration, private room decoration cooperation, charter furnitureselection, audio equipment installation, audio equipment parametersettings.
Thereare many types of KTV audio equipment, and there are manyconfiguration and combination schemes. Choosing the best matchingfrom many devices is a project. The general direction of KTV audioequipment configuration pays attention to eight words: singercomfortable, listener comfortable, or sing, singing, singing,singing, singing, singing, singing, singing, singing, singing,singing, singing, singing, singing, singing, singing. Comfortable andcomfortable. It can be described as the mantra. We analyze the KTVaudio configuration from these eight words.
Thetraditional Karao OK merged pays attention to theperformance price ratio, complete function, and moderate price,including all facilities required by karaoke: audio and videoswitching, music rise and fall Zooming, microphone sound, microphoneecho effect control, effect volume control, microphone total volumecontrol, total music volume control, infrared remote control, poweramplifier, etc. Due to the limitations of machine functions andmachine body shape, theoretical power is within 180W, of course, ofcourse The best practical power is between 80W and 150W.
