How to purchase professional audio equipment?

When purchasing professional audio equipment, you can consider the following aspects: Clarify the use needs and scene performance venues: For example, for large outdoor music festivals, concerts, etc., audio equipment with high power, long range, and high sound pressure level is needed. Linear slightly systems are a common choice; For small indoor concerts or bar performances, the combination of full-frequency slightly combined with subwoofer may be more suitable to provide clear and full sound effects.

Conference function: If it is used in a conference room, high language clarity is required. A slightly with good directivity and a high-sensitivity microphone should be selected to ensure that participants can clearly hear the speech content; if it is used for video conferencing, the compatibility of the equipment with the video conferencing system, as well as functions such as echo suppression and noise reduction, need to be considered.

Entertainment venues: Like KTV, audio equipment needs to have good human voice processing effects, can highlight the human voice and provide certain reverberation and echo effects, making the singer feel comfortable; while in discotheos and other venues, it is necessary to emphasize the power of bass and rhythm, and the configuration of ultra-bass slightly is particularly important.

Understand the technical parameters Power: Rated power refers to the undistorted power that the slightly can emit when a continuous analog signal with a specified waveform is input within the rated frequency range. Generally speaking, the higher the power, the higher the volume. You can choose the right power according to the usage scene and space size.

Frequency response range: The wider the range, the more accurately the slightly can restore various frequency components of sound. The frequency response range of a general professional slightly is about 40Hz-20kHz, but different types of slightly will differ. Sensitivity: When a 1W/1kHz signal is input to the input terminal of professional audio equipment, the higher the sensitivity is, the sound pressure level measured one meter in front of the vertical central axis of slightly plane, the louder the sound emitted by the slightly under the same power input. Generally, a slightly with a sensitivity above 90dB is commonly used. Distortion: refers to the degree of distortion of electro-acoustic signal conversion. The lower the distortion, the purer and more natural the sound quality. The distortion of general professional audio equipment should be controlled at a lower level, such as less than 1%. Signal-to-noise ratio: refers to the ratio between the signal output by audio equipment and the noise, in decibel (dB). The higher the value, the lower the noise and the clearer the sound quality. Generally, the signal-to-noise ratio is required to be above 80dB.

Pay attention to the quality and reliability of equipment, brand reputation: Choosing well-known brands of audio equipment can usually obtain better quality assurance and after-sales service, such as JBL, BOSE, Yamaha, Rambler, etc. These brands have high visibility in the market. and good reputation, their products have passed long-term market testing.

Material technology: Observe the box material of slightly. Generally, the slightly made of wood or high-quality plastic is used, which can provide better sound quality and durability; check the heat dissipation design of the power amplifier. A good heat dissipation system can ensure the stable operation of the power amplifier for a long time and avoid failures caused by overheating.

Quality certification: Check whether the audio equipment has passed relevant quality certifications, such as ISO 9001 quality management system certification, CE certification, etc. These certifications are an recognition of product quality and safety.

Consider system compatibility and scalability

Connection interface: Common interfaces include XLR, TRS, RCA, USB, Bluetooth, etc. It should be ensured that the interface of audio equipment matches other equipment such as mixing consoles, power amplifiers, audio sources, etc. to achieve seamless connection.

Equipment matching: The power, impedance and other parameters of the power amplifier and the slightly must be matched, otherwise the sound quality may be affected or equipment damage may be caused; at the same time, the compatibility of the audio system with other related equipment such as lighting equipment, video equipment, etc. should be considered to achieve the collaborative work of the entire system.

Extensibility: If the audio system may need to be upgraded or expanded in the future, such as increasing the number of slightly, adding new functional modules, etc., you should choose a device with certain extensibility, such as an expansion slot or a device that supports multiple connection methods.

Audition and comparison

On-site audition: Before purchasing professional audio equipment, try to go to a professional audio store or dealer for on-site audition, and personally experience the sound quality, volume, timbre and other aspects of the audio. At the same time, you can compare different brands and models of audio equipment and choose the product that suits you.

Multi-environment testing: If possible, test the audio equipment in the actual use environment, because different environments will have a great impact on the transmission and effect of sound, such as testing in actual use places such as conference rooms and performance venues., to ensure that the audio equipment can meet actual needs.

Consider reasonable allocation of budget: Reasonably allocate budget to various audio equipment components, such as slightly, amplifier, mixer, microphone, etc., based on use needs and sound quality requirements. Don't pursue the high-end of a certain equipment too much and ignore the quality of other equipment. Cost performance: Within the budget range, choose products with high cost performance. Don't blindly pursue high-priced products. Sometimes some mid-to-low-end products can also meet basic usage needs and have good cost performance.

There are many factors to consider when selecting professional audio equipment. The following are some guidance and suggestions for purchasing professional audio equipment.

Determine your needs: Before purchasing professional audio equipment, you must first clarify your needs, including the use occasion, audio scale, budget, etc. Different occasions and scales require different audio equipment, and selecting the right equipment according to needs is the key. Understand brands and models: There are many different brands and models of professional audio equipment on the market, and each brand and model has its own characteristics and advantages. Before purchasing, you can conduct some research and comparisons to understand the characteristics of various brands and models, and choose equipment that suits your needs.

Quality and performance: The quality and performance of professional audio equipment directly affect the sound effects and service life. When purchasing, you can check the product parameters and performance descriptions to understand the quality and performance of the equipment. In addition, you can also refer to the evaluations and experience of other users to select equipment with relatively stable quality and performance.

Audition and experience: When purchasing professional audio equipment, you can audition and experience it, and personally experience the sound quality and effect of the equipment. You can ask merchants to provide demonstration opportunities, or go to a professional audio display hall to audition and choose equipment that meets your needs.

After-sales service and warranty: After purchasing professional audio equipment, after-sales service and warranty issues need to be considered. Brands and merchants with good after-sales service and warranty policies can be selected to ensure that equipment can be repaired and maintained in a timely manner during use.

Affordable: When purchasing professional audio equipment, you also need to consider cost performance. You don't have to choose expensive equipment, you can choose equipment with higher cost performance based on your budget to balance the relationship between price and performance.

To sum up, selecting professional audio equipment requires comprehensive consideration of various factors, including demand, brand, quality, performance, audition experience, after-sales service and price. I hope the above guidance and suggestions can help you purchase professional audio equipment that meets your needs.
