What is a capacity clam? Distinguishing the structure and function of shells on amply

You wonder when choosing an amp with how many shells because you do not know its function. So what is the power on the amp? Structure, function and how to distinguish them? Let’s find out with Tnhelearning.edu.vn!

What is a capacity clam?

Scallop capacity is understood as a semiconductor component (Transistor) that determines the power of the amplifier to help amplify the signal most effectively and is applied in many types of electronic devices, especially karaoke amplifiers.

People call it scallops because in the past, their external design was very similar to sea scallops. With specific use is to help amplify the audio signal, so the capacity does not directly affect the good or bad quality of a device.

The structure and operating principle of the power clamshell in the amplifier

The amplifier operates on different classes of circuitry including: class A, class AB, class B and the most widely used are ClassAB Push-Pull and ClassA Single-End.

Class A Single End

The operating point of this layer is at the midpoint of the load route. Here, the audio signal will be amplified to the maximum and taken care of by a scallop.

The advantage of using this Class A amp is that there are no nonlinear regions and very little distortion due to only 1 active scallop. Besides, the use of this power clamshell also brings about good and natural sound quality.

However, when using Class A, the efficiency is very low, about 25%, and the remaining 75% will radiate heat on equipment or electronic lamps. Therefore, it will lead to the size as well as the cost of heat dissipation for scallops.

Class AB push and pull

At the condensate areas on the transmission solid lines, only 50% of the input signal is amplified, so there must be 2 or more cocks at this time, 1 cock is used to amplify the positive signal and 1 cock is used to amplify the positive signal. Scallops are used to amplify the negative signal ie 1 push and 1 pull.

The advantage of this class is that it has a push-pull design with very high performance that makes the speaker output power much higher. This makes the sound very loud and is used in large areas such as halls and large stages.

Function of power clamshell on amp

Amplifier has the function of deciding the power of amplifying the sound in the amp.

With small power amplifier devices, the number of clams depends on the capacity of each line and does not have a specific, fixed number. As for the common equipment with a larger capacity, the number of cockles also increased significantly and was very large.

Thus, the use of scallop capacity depends on each device and its capacity requirements. Increasing the number of shells in an amp is an increase in the power of the device.

How to distinguish clams on amply

Classify amps by design

Based on the design and appearance, there are 2 types of scallops, round scallops and square scallops.

Classification by structure

Based on the structure, there will be 2 types: iron oysters and coal oysters. Iron oysters are shells made of iron or aluminum, while shells are made of synthetic plastic or ceramic.

Classification according to usage function

This is the most important criterion to distinguish clams amply. According to the function used, people have scallops (FET, MOSFET) and ordinary oysters (BJT). In each type of cockle, it is divided into 2 different types: forward and reverse oysters.

Sort by color

In terms of color, scallops also have 2 types, which are blue scallops and black scallops.

What is the difference in the capacity of the shells on the amp?

On the market today, there are many types of amps with different numbers of clams, including: 4 clams amply, 8 clams amp, 16 clams amp, 24 clams amp, 32 scallops amp

Amply 4 oysters, 8 oysters or 12 oysters will have different capacity and it does not depend on any common number, but it will depend on what manufacturer uses and the number of oysters as well as the capacity of the amplifier. How much is used?

The number of clams of the amp represents the capacity of the device. The larger the capacity, the greater the number of cockles and vice versa. Typically in karaoke amps do not need too large capacity, so the number of cockles is only 4, 8, 12, and 16 clams, while for large capacity amps, the number of clams can be up to 24 clams or 32 scallops.

Above is the definition of power clamshell as well as the function and structure of clams on amply, hopefully through this article can provide a lot of useful information for you!
