If you want to install a set of ceiling speakers at home, why do you need to buy an amplifier? Can't you connect the speaker directly to the TV?

The TV is directly connected to the speaker, and the sound effect will be worse than the sound quality after connecting to the amplifier. Because the output voltage and current of most TV audio or ** output ports are relatively low, generally around 5-20V.

Such a voltage is sufficient for headphones or low-power speakers, but not enough for good speakers, resulting in a small sound and susceptibility to interference and noise.

Secondly, the audio output port of some TVs is usually analog signals, and they will be affected by electromagnetic interference and signal loss inside the TV, resulting in a decrease in the signal-to-noise ratio and an increase in distortion. Such a signal has a detrimental effect on the clarity and realism of the sound.

On top of that, most TVs don't usually have an equalizer on the audio output portIn other words, they cannot adjust the high-frequency and high-frequency balance and sound field effect of the sound according to the characteristics of different speakers and rooms. Such a signal has a detrimental effect on the balance and three-dimensionality of the sound.

Whereas, the amplifier works by amplifying the audio signal to a level sufficient to drive the voltage and current of the speaker.

First of all, it will receive the audio signal from the ** device or other audio sources, and then the built-in DSP sound processing chip will carry out some pre-processing of the input signal, such as gain adjustment, equalization adjustment, signal selection, etc., to adapt to different audio sources and sound quality requirements.

The pre-processed signal is then amplified to increase the voltage and current levels of the signal, allowing it to drive professional ceiling speakers, such as WEILICO; Finally, the amplified signal is output to the ceiling speaker.

In the process of processing audio signals in the power amplifier, the large capacitors inside it can store and release electrical energy, so as to provide stable voltage and current for the power amplifier, reduce fluctuations and noise, and improve the performance and sound quality of the power amplifier.

The channel separation of the H2300 amplifier is 65dB, the larger the value, the smaller the interference between the two independent audio signals (left and right channels) in the amplifier, and the better the three-dimensional sense and clarity of the sound. The channel separation is 65dB, which means that the interference between the two independent channels will not exceed 65dB at any frequency, which is a relatively high standard.

If you want to enjoy cinematic cinematic effects at home, you need to make sure that the amplifier, ***, speaker, and film source support most high-quality audio formats, so as to get the best viewing experience.
