How to choose the power amplifier?These points are very practical.

In a set of audio, the function of the power amplifier is to amplify the input signal of the preamplifier and output it to the speaker.

In this process, the power amplifier also performs some protective processing on the input signal to ensure that the input signal is sufficiently pure. 

When buying a power amplifier, if you are not accompanied by a senior enthusiast, you can only rely on yourself to choose or listen to the introduction of the salesperson.

When you request a piece of music to listen to it, the salesperson will also selectively play some music suitable for playing on this amplifier, which makes it difficult for you to distinguish the performance of the amplifier.

Here, you may wish to understand some parameters and selection methods , No longer have to blindly move the machine.

Output power:

The output power needs to be coordinated with the impedance of the speaker, and speakers with different impedances will have different output powers. In order to reduce the distortion at high power output and obtain better results, the output power should have a certain reserve power, and choose a slightly larger one.

Frequency response:

Does the frequency response meet the minimum requirements for music? We know that music has high, medium, and low bass, and the highest notes of some musical instruments are often above 4 kHz. Coupled with the higher harmonics of these trebles, a high-frequency response is required. Some instruments have a minimum frequency of only 20 Hz.

Dynamic response:

The dynamic response tests the power amplifier's ability to handle strong and weak signals.When playing a piece of music or singing a song, the sound is only a few dB when the sound is small, and it can reach more than 90 dB when the sound is loud. 

When the amplifier is used to process very large or small signals, other performance will tend to be reduced. This requires a larger dynamic range to maintain performance under extreme conditions.Therefore, the dynamic range of the power amplifier requires at least 5–100 dB.

Signal-to-noise ratio:

The signal-to-noise ratio index should reach the maximum possible ratio; that is to say, the noise should reach the minimum level compared to the signal sound, which is like being so quiet that a needle can be heard on the ground.

Having said so many methods, now I will introduce a hot-selling amplifier from our company, the TA Series Class D modular power amplifier.

It is suitable for mobile performances and fixed projects Internationally, the most advanced modular design The TA series digital amplifier is based on modular design,adopts the most advanced Class D amplifier circuit in the world, has an efficiency conversion rate of over 90%, adopts the new generation of Class-D audio amplifier technology, and adopts pulse width modulation technology (PWM technology). Its working principle is to use the amplitude of the analog signal to modulate the width of a series of rectangular pulses.

Pulse modulation Use a constant-amplitude triangle wave to sample the analog audio signal.

The treble level is clear and sweet, and the low frequency is thick and powerful.

Compared with the traditional AB-type power amplifier, it has the advantages of high explanatory power, clear treble and sweet sound,thick and powerful low frequency, light weight, high work efficiency, low working temperature, good stability, and other advantages.

T.I Audio power amplifier is based on the above-mentioned audio applications, combined with the characteristics of T.I Audio speakers, to develop a series of Class D amplifiers for different application needs.

The scale of T.I Pro Audio factory is incomparable among other factories in the local audio industry. We have a professional design team, an aesthetic chamber, and a R&D team.indoor and outdoor showroom assembly line workshop, etc 

100 production line staff, over 10,000 square meters of factory space, an 8-talent engineering team with over 20 years of experience in pro audio systems, and 50 international sales in local and overseas.

Last but not least, we hope our information can help you choose the power amplifier. If you also like this TA series power amplifier, please contact us. We are a pro audio equipment manufacturer in Guangzhou, China.

Thanks for watching.
