There Are Several Common Speakers, Effects, Amplifiersng That Can Be Properly Matched To Improve The Cost-effectiveness Of Sound Engineering.

Speakers are classified into conference speakers, card speakers, and professional speakers.




Conference room speakers: As the name suggests, they are speakers for conference rooms. The main advantages are affordable, low power, and one amplifier can drive several conference room speakers at the same time, saving power. The disadvantage is that the bass, middle and treble are not clear. Whether it is used to listen to songs or sing, there is no sense of power.

It is only suitable for sound reinforcement when talking in a conference room. The sound quality is dry, there is no three-dimensional sense and penetration, it is not suitable for listening to songs or watching movies, and it is not suitable for singing.




Card package speakers: common in small boxes of KTV Main advantages: High quality, smooth, soft, moderate power, suitable for indoor use. The disadvantages are: the bass, midrange, and treble are not clear enough, the sound is not clear, and the power is not strong.

The price and product performance are satisfactory, and it is still possible for people with low singing requirements. It is an entry product in singing speakers.




Professional speakers: Commonly used in KTV boxes and stages. The main advantages: strong sound quality and sufficient power, suitable for KTV engineering and outdoor stage use. Disadvantages: It is easy to disturb the people in the home, and the tuner needs to handle the effector carefully, otherwise it is easy to scream and damage, and the price is high.

Professional speakers are high-profile speakers in audio engineering. Professional singers use this type of speakers for concert audio, which has a high singing pressure and strong sound.






The classification of effects is more common analog effects, digital pre-effects




Amplifier's built-in analog effects: Some amplifiers have built-in analog effects, and the amplifier can directly output the sound to achieve the amplification function. These types of effects are generally simple, that is, simple reverberation, echo, and howling suppression functions. Precise tuning. Some big brand products come with a simple version of the equalizer.

This effect device is mostly used in conference room sound engineering, and can only meet ordinary sound reinforcement functions.




Ordinary analog effects: This type of effects is simple and easy to debug. It has: vocal bass, midrange, treble, echo, reverb, howling suppression processing, etc. Background sound: bass, midrange, treble Adjustment function.


However, this type of effects cannot be accurately tuned, and some low-profile audio projects are used. For KTV venues, most customers do n’t know whether the effect is good or not, and it can meet ordinary people ’s requirements for KTV sound effects.




Digital pre-effects: This type of effect is commonly used in KTV entertainment venues. Compared with the previous two products, it is a bit more complicated to debug. It has the function of independently adjusting the equalizer of human voice and background sound. Echo and reverb of singing can be used. Adjustment. It can adjust the human voice and background music more accurately. It belongs to the standard effects of KTV.

Amplifier classification: pure rear-stage amplifier, merged amplifier




Pure rear-stage power amplifier: Pure rear-stage power amplifier needs to be used with effect devices. This type of power amplifier is relatively powerful, simple in function, and long in service life. It is often used in singing places such as stage and KTV.

Combined amplifier: Combined amplifier is an amplifier with effects. When speaking about effects, it is very clear. This type of power amplifier is not very powerful and is mainly used for conference room sound reinforcement, and is not suitable for KTV singing.


Microphone classification: ordinary microphone, KTV microphone, performance microphone




Ordinary microphone: domestically produced microphones, produced by small factories, generally within 800 yuan (one pair), and affordable. It is mainly used for sound reinforcement and not suitable for singing.


KTV microphone: domestic brand microphones generally cost less than 2,000 yuan (one pair), durable, affordable, good overall performance of pick-up, cost-effective, suitable for entertainment venues.

Performance microphones: expensive 5,000 yuan (one pair) upwards, mainly Shure, Sennheiser and other products, suitable for stage or personal use, the products are delicate, easy to wear, not suitable for entertainment venues.

All sound engineering follows the principle of wooden barrels. The reason why it is called sound engineering is because it is a systematic project, not a separate product. Speakers, microphones, amplifiers, and effects can be combined to achieve the function of sound reinforcement.




When we are doing engineering, the attributes of the product must be well matched. For example, we do professional speakers for KTV sound engineering, pure post amplifiers, and digital preamps. At this time, we cannot choose the cheapest microphone when choosing a microphone. Otherwise, the sound quality is Can't get out. But there is no need to buy a performance microphone.
