How to distinguish high and low bass in a single channel amplifier?

1.Just connect to the output end of the 6-inch speaker, and add a tweeter in parallel.

2.But your woofer and tweeter need capacitors to divide the frequency in order to have a better sound.

3..The simplest crossover:

Woofer: connect a 10 micromethod 100V unlimited capacitor in parallel (Lu Xie capacitor is very good, and it can be bought in general electronic city), or you can do without this capacitor.

Tweeter: series a micro-method 100V Lu solution capacitor, and then a 7W4 ohm cement resistor. (Your tweeter may not have enough power and is prone to burn out, so connect a little 4 ohm resistor in series to reduce a little power to the tweeter; If the treble is insufficient, don't use this resistor).

4.You say the sound is weird, you use a piece of pipe to make a speaker, such a speaker is just a subwoofer, too much bass eats up the middle and high tones, so the sound is very muffled, not good.

5.The tweeter can be fixed to the water pipe of the woofer, or it can be placed in any place, but the front of the horn needs to be facing your ear and at the same height as your ear; Because you only have one channel, there is no question of direction; If you make stereo speakers in the future, the situation will be very different.

6.Your 6-inch speaker can't be a special speaker for a subwoofer, if it is, you need to add another midrange speaker, because the subwoofer horn wood has a midrange and treble, you also need to add a 45w8 ohm midrange speaker. (You'll need to buy a three-way to connect the three speakers.)

1.The tweeter and woofer on the speaker are separated from the treble and bass through the crossover inside.

There is a resistor, capacitor and inductor in the frequency divider to form a passive filter, which divides the input full-range signal into two or three divisions. The so-called two-way frequency is divided into treble and bass, and then connected to the treble and woofer; The three-way frequency is divided into treble, midrange and bass, and then connected to the treble, midrange and woofer, so there will be one more midrange speaker than the two-way one.

In order to reduce costs, many manufacturers connect the bass directly to the input, and then connect a series of condensers to the tweeter to form a simple crossover. This type is more common on multi-** speakers and coaxial speakers.

2.Strictly speaking, the tweeter and the bass cannot be said to be in parallel, because they are not directly connected. The definition of parallel connection is to connect directly together, if the tweeter and woofer are directly connected together, the treble will most likely burn out.

It should be said that the tweeter and the woofer share the input signal more rigorously.

3.If there is a full-range speaker, it can be directly connected to the output of the power amplifier, of course, to ensure that the power meets the requirements, otherwise the speaker will be burned.

Two positive electrolytic capacitors with a withstand voltage of 50V are connected to each other, leaving two negative poles to connect one end of the tweeter and one end of the audio output, and the other end of the tweeter to the other end of the audio output.

Summary. Why is the two-channel amplifier board divided into high and low tones?

The left and right channels are separated. An independent transmission signal is formed by signal + ground, that is to say, the left and right channel transmission is composed of left channel signal + ground wire, and right channel signal + ground wire.

What you said about the formation of a treble to the power amplifier, it may be that the signals of the left and right channels are gathered to the input of the power amplifier, and the ground wire is not connected, which is equivalent to only two signals working, so the signal of one of the channels plays the role of "ground", and the two groups of sounds are mixed together to form the "treble" you are talking about, this treble has characteristics: the sound is sharp and thin, accompanied by echoes (it sounds distant), which is the strange sound formed by the mixing of the two channels.

In the early days, many power amplifiers used the characteristics of mixing the left and right channels to simulate "Liyin", which was dedicated to the center (surround sound: left channel - right channel - center in the middle of the left and right channels).

If you used to use it normally, but now it is not normal, it may be that your amplifier conversion is not complete, resulting in the phenomenon of "mixing", or because your signal cable is damaged to ground, resulting in "mixing".

This phenomenon is very simple to operate, the process does not exceed 1 minute, and the description is cumbersome.

Please wait patiently for 3 minutes, we are sorting out, and we will answer you immediately, and please do not end the consultation.

Why is the two-channel amplifier board divided into high and low tones, and the left and right channels are separated by Zhenxiang independently. An independent transmission signal is formed by signal + ground, that is to say, the left and right channel transmission is composed of left channel signal + ground wire, and right channel signal + ground wire. What you said about the formation of a treble to the power amplifier, it may be that the signals of the left and right channels are gathered to the input end of the power amplifier, and the ground wire is not connected, which is equivalent to only two signals working, so the signal of one of the channels plays the role of "ground", and the two groups of sounds are mixed together to form a laugh with the "treble" you are talking about, and this treble has characteristics:

The sound is shrill and echoy, which sounds distant, and this is a strange sound formed by the mixing of two finger channels.

The easiest way to look at the symmetry, such as the devices on it are all two sets, most of them are upright. Note, but it's all two sets.

Connect the power supply, audio source, and speaker, and listen to it.

……This is a synthetic noun, to explain it to you like this, first explain the audio amplifier:

The full name of audio power amplifier is audio power amplifier, which is used to promote the sound of the speaker to reproduce the sound, and it is used in all electronic products that produce sound. An audio amplifier is actually an amplification of a smaller audio signal, increasing its power, and then output. The pre-amplification is mainly to complete the amplification of the small signal, and use a co-directional amplification circuit to amplify the voltage of the input audio small signal to obtain the input required by the latter stage.

The latter episode focuses on amplifying the power of the audio so that it can drive the resistor to get the desired audio.

And the two-channel is now the popular stereo, with two speakers or a subwoofer. (The single-channel power amplifier has only one output channel and only one speaker, which has been eliminated).

As for the word "professional", I don't think there is much to explain.

Can the landlord understand this?

Is it better to have a master volume or a high and low bass adjustment for a digital amplifier? Hello, with high and low friends of the town tone adjusted. The difference between a digital amplifier with high and low tones and only one master volume is that the former can change the color and effect of the sound by adjusting the high and low tones, while the latter can only control the sound volume by adjusting the master volume.

Therefore, which is better depends on individual needs and use scenarios. If you need more freedom to control the effects and colors of the sound circle and silence, or need to adjust it for different types or scenes, then a digital amplifier with high and low pitch adjustment may be more suitable for you. But if you just need to simply control the sound volume and don't need too many adjustment features, then a digital amplifier with only one master volume will also meet your needs.

The woofer on the other side is broken.
