Audio rental knowledge: 4 common types of professional audio and their application scenarios

Knowledge of Audio Equipment Rental and Services: Common Types of Professional Audio Equipment, Application Scenarios, and Their Advantages and Disadvantages

According to the data in the "2024 Global Professional Audio Equipment Market White Paper", professional audio equipment accounts for 68% of the market share in the audio field, indicating a very broad market.

Professional audio equipment is also one of the many types of audio equipment. Compared with Hi-Fi audio equipment, professional audio equipment does not have such high requirements for sound quality. Instead, it has higher requirements for volume and needs to restore the effect of human voices.

Moreover, its difference from most audio equipment lies in the different usage scenarios. Professional audio equipment is often used in business KTVs, bars, private clubs, stage performances, opera houses, stage sound reinforcement, and corporate conference systems.

Furthermore, a professional audio system is not that simple. It requires the construction, design, and connection and debugging of audio equipment, which need to be completed by professional audio technicians. And all these require professional audio equipment rental companies to provide installation and technical support services.

Although technology is developing rapidly nowadays, professional audio equipment can generally be divided into four categories: karaoke package speakers, professional full-range speakers, professional coaxial speakers, and line array speakers.

So, what are the classifications, application scenarios, advantages, and disadvantages of these professional audio equipment? Next, we will analyze in detail for you through this knowledge of audio equipment rental: common types of professional audio equipment, application scenarios, and their advantages and disadvantages.

I. professional audio types：Karaoke Package Speakers

Karaoke package speakers are also known as "karaoke speakers". As the name implies, they are mainly used in small-space business KTVs. They are usually divided into two types: five-unit three-way speakers and three-unit two-way speakers.

Karaoke package speakers use a bass unit with a foam surround, which has good low-frequency extensibility. If a professional frequency division circuit is used to perform phase calibration and dynamic compression processing on the mid-low frequency band, the vocal restoration degree in the 100-500Hz frequency band will be significantly improved.

The rated power of a standard karaoke package speaker is 150-200W RMS, and the maximum sound pressure in a small to medium-sized private room of 10-20 square meters is 105dB. Its cabinet is designed in a closed manner, which can suppress low-frequency standing waves.

Suitable Places: Small-space business KTV places, such as the small private rooms of Limited Edition KTV.

Place Configuration Scheme: In a KTV place, a standard private room (15-25 square meters) adopts a dual-speaker stereo configuration with separated left and right channels. For VIP private rooms larger than 30 square meters, a subwoofer needs to be added to supplement the low-frequency part.

Advantages: The five-unit three-way or three-unit two-way design allows this kind of audio equipment to process human voices more delicately, making it suitable for singing.

Disadvantages: The rated power is small, so multiple pairs of speakers are needed in a large-space KTV. If used in a large-space KTV, a high-power amplifier needs to be matched to avoid sound distortion. Moreover, a subwoofer is required to enhance the low-frequency effect.

II. Professional Full-Range Speakers

Professional full-range speakers are significantly different from karaoke package speakers.

Professional full-range speakers are designed in a vertical style and are mainly composed of 2 units (horn tweeter and bass speaker). Professional full-range speakers have a strong directivity, and can withstand high power and sound pressure levels.

The installation requirements for professional full-range speakers are relatively high. In addition to considering their horizontal directivity, the vertical directivity of the installation also needs to be considered. In terms of materials, the tweeter unit of professional full-range speakers uses an aluminum diaphragm, so its mid-high frequencies are relatively bright, with strong penetrability, making it easy for people to sing and ensuring stable sound quality.

Generally speaking, professional full-range speakers use a high power between 400W and 1000W, and the sound pressure level can reach 130dB, with good sensitivity and power.

Suitable Places: Professional full-range speakers are more suitable for larger spaces, such as outdoor stages and large indoor event venues.

Advantages: Professional full-range speakers have high power handling capacity, high sound pressure level, bright mid-high frequencies, strong penetrability, good sound quality stability, and high sensitivity.

Disadvantages: Since many factors need to be considered during the installation of professional full-range speakers, and the installation angle needs to be precisely controlled, and they are large in weight and volume, so they are more troublesome to carry and install.

It is recommended that when you rent this kind of audio equipment, you can let professional installers be responsible for the installation, and precisely adjust the directivity through brackets or hanging. In addition, an equalizer can be added to compensate for the audio shortfalls and optimize the sound quality. Moreover, due to the strong directivity of this speaker, for some corners that cannot be covered by the sound, it is advisable to consider using independent speakers in multiple areas.

III. Professional Coaxial Speakers

The main difference between professional coaxial speakers and professional full-range speakers is that the tweeter and woofer of professional coaxial speakers emit sound on the same axis, which makes them very suitable for home use.

Therefore, the sound of professional coaxial speakers is highly synchronous in frequency. No matter how the listening position changes, the tweeter and woofer can reach the listener simultaneously, making the tweeter and woofer highly synchronized and ensuring the texture of the music.

Although professional coaxial speakers have a small phase distortion, a relatively simple frequency division method can make the sound more delicate and reduce the distortion degree.

Suitable Places: Professional coaxial speakers perform excellently in the field of home karaoke, and are also suitable for private cinemas and small music studios with high requirements for sound quality.

Advantages: The tweeter and woofer emit sound on the same axis, solving the problem of the distance difference between the tweeter and the woofer. The sound is delicate, rich in details, and the human voice is soft.

Disadvantages: At present, there are few professional audio brands that can master the coaxial audio technology, and the price is relatively high, with fewer brand choices.

Since the price is relatively expensive, you can pay attention to emerging brands or second-hand equipment to reduce costs. For the detailed disadvantages of this type of audio equipment, you can match it with an external frequency divider to optimize the frequency division design, and then use sound-absorbing materials to reduce standing waves.

IV. Line Array Speakers

The full name of line array speakers is "linear array speakers", which are only used for commercial activities and performances and are not suitable for home use.

A linear array is a group of radiation units arranged in a straight line with a close interval, having the same amplitude and phase, and the number and angle can be flexibly adjusted.

Line array speakers improve the transmission distance through a linear transmission method, reduce the attenuation of sound during long-distance transmission, have a wide sound coverage area, and are powerful. They are suitable for large-scale places such as large theaters, gymnasiums, or outdoor stage performances.

Suitable Scenarios and Places: Used in large-scale places, such as large theaters, gymnasiums, and large outdoor stage performances.

Advantages: The full name of linear array speakers, with a wide sound coverage area, strong power, and high volume, can still play powerful sounds in large and open places.

Disadvantages: The equipment cost of line array speakers is high, and they are large in size and high in cost, not suitable for home use, and only suitable for commercial use. Moreover, they require professional technicians for system construction and debugging, and have high requirements for the installation environment.

If you are organizing large-scale activities and outdoor performance activities, this type of equipment is very suitable. It is recommended that when you rent this speaker system, invite technicians to help optimize the angle and quantity to avoid wasting resources.
