Professional audio refers to a high-fidelity audio system designed and manufactured for specific application scenarios

Professional audio refers to a high-fidelity audio system specially designed and manufactured for specific application scenarios. It is widely used in performances, recordings, conferences, KTV, home theater and other occasions. The following is a detailed introduction to professional audio:

Classification of professional audio

Classification by application scenario: Performance audio: used for large-scale performances such as concerts and concerts, characterized by high power, high-fidelity, and high sensitivity. Recording sound: Used in recording studios and radio stations, emphasizing high-fidelity and sound reproduction. Conference audio: Used for meetings and speeches, focusing on high quality, low latency and voice optimization. KTV audio: Used in entertainment venues, emphasizing the restoring power of sound and multi-channel sound effects. Home theater audio: Used in home theater systems, pursuing high-fidelity and surround sound. Audio in public places: Used in shopping malls, squares, etc., requiring high reliability and large coverage.

Classification by slightly type: Card bag slightly: suitable for commercial KTV in small spaces, usually divided into five-unit three-frequency and three-unit two-frequency. Professional full-frequency slightly: adopts a 2-unit design, suitable for professional occasions, with high directivity and high sound pressure level. Professional coaxial slightly: Treble and bass sound on the same axis, suitable for home and small places. Linear array slightly: suitable for large places, such as gymnasiums and theaters, with wide sound coverage and strong power.

Characteristics of professional audio

High-fidelity: Professional audio pursues high-fidelity sound quality to ensure sound restoration and delicacy. High sensitivity: Capable of capturing small sound changes and providing clear sound effects. High power and high sound pressure levels: Meet the needs of large spaces and high-load operations, and ensure sound coverage and transmission. Low noise and good bass effects: Reduce background noise, provide strong bass effects, and enhance the sense of presence. Durability and stability: Long-term operation and harsh environments are considered in the design to ensure the reliability and stability of the equipment.

Application scenarios of professional audio

Shows and concerts: Professional sound systems are used for large-scale performances and provide high-quality sound effects and coverage. Recording studios and radio stations: High-fidelity audio equipment ensures pure and authentic sound quality for recordings and broadcasts. Meetings and lectures: Professional sound systems provide clear voice transmission and good communication. KTV and entertainment venues: High-fidelity audio equipment creates an immersive sound experience and enhances the singer's experience. Home Theater: Professional sound systems provide high-fidelity and surround sound to enhance the movie-watching experience. In public places: such as shopping malls, squares, etc., professional sound systems ensure the coverage and dissemination of sound to meet the needs of large spaces.

When applying professional audio in home theaters, there are some common misunderstandings that may affect the final viewing effect. Here are some typical misunderstandings and ways to avoid them:

1. DIY combination saves money

Myth: Many users believe that as long as they purchase the right playback equipment, signal processors, stereos and projectors, they can build their own home theater, believing that this can save costs.

Avoiding methods: The construction of a home theater is a complex project involving multiple technical levels, including equipment selection, acoustic design, system integration, etc. DIY without professional knowledge may cause device performance to not be fully utilized or even incompatible issues. It is recommended to consult professional opinions or hire a professional team to plan and design before starting construction.

2. The higher the price, the better the effect

Myth: Many people believe that by investing in expensive high-end products, they can instantly get a great home theater experience.

How to avoid it: The effects of home theater are determined by the collaborative work of the entire system, not by a single device. When purchasing equipment, we should pay attention to the overall coordination and balance, not just the high-end degree of individual equipment. Choose cost-effective products based on your actual needs and budget.

3. Place the subwoofer at will

Myth: When installing a theater system, many people will place the subwoofer casually in the corner of the room, thinking it is convenient.

How to avoid it: The placement of the subwoofer requires more careful consideration. In the early stages of building a home theater, the size and model of the subwoofer should be carefully planned to match the acoustic characteristics of the room. After installation, careful debugging is carried out to determine the position of the subwoofer based on the actual listening experience.

4. Ignore the impact of the environment on sound effects

Myth: The sound effects of home theaters are only affected by the equipment itself, ignoring the acoustic characteristics and spatial layout of the room.

Avoiding methods: When building a home theater, you must fully consider the acoustic treatment and spatial layout of the room, and carry out professional design and planning to ensure the sound experience. This includes the use of sound absorbing materials, diffusers, etc. to optimize the sound field.

5. Excessive reliance on brand effects

Myth: Some consumers blindly pursue well-known brands, believing that brand awareness is a guarantee of product quality.

Avoiding methods: When purchasing home theater equipment, you should comprehensively consider the product's performance, quality, after-sales service and other factors, and make choices based on your actual needs, rather than simply relying on the brand's market influence.

6. Ignore acoustic processing

Myth: Think that acoustic treatment is not important as long as the equipment is well configured.

Avoiding methods: Acoustic treatment is a very important part of the construction of home theaters, including sound absorption, sound insulation, diffusion, etc. It is recommended to hire a professional acoustics company for design and construction to ensure sound effects.

7. Improper selection of wire

Myth: When selecting wire, think that the more expensive the better, or ignore the impact of wire on sound quality.

How to avoid it: Choosing the right wire is very important, but you don't have to go after expensive ones. A cost-effective wire should be selected according to actual needs, and factors such as the length and shielding effect of the wire should be paid attention to reduce signal loss and interference.
