What is the 4 wires of the pre output of the combined power amplifier?

On one side is the 220V input. On the other side is the output. The four wires you're talking about are the (multi-voltage) outputs. You can test it with a multimeter. The highest resistance is the input. The one with a small resistance value must be the output!

The 4 counties that merge the power amplifier output are divided into wire lines and live lines, and there is also some lines that are uh information, and these 4 lines are these lines.

The four lines are the audio signals of the left and right channels.

Generally, there should be many kinds of such public output capital lines, right?

Summary. The amplifier has four output binding posts, can it be connected to four speakers?

It doesn't matter how many binding posts there are, the key is that the resistance value and the power should match. The amplifier is two-channel, so you can divide the four speakers into two groups to connect, and connect the two speakers in series to see how the effect is. Because the resistance of the speaker will increase to 16 ohms after series connection, if it is weak, the special bass effect is not good.

Hello, I have seen your question and am sorting out the answer, please wait a while

There are switches in front of the two wiring mains, you can open one group, you can also open two groups, if you add four main sound effects will be good.

So unanswered.

The power amplifier has four output binding posts, can it be connected to four speakers, it doesn't matter how many binding posts there are, the key is that the resistance value and power should match. The amplifier is two-channel, so you can divide the four speakers into two groups to connect, and connect the two speakers in series to see how the effect is. Because the resistance of the speaker will increase to 16 ohms after series connection, if it is weak, the special bass effect is not good.

The four binding posts are estimated to be "parallel" to the output port of one amplifier. That is to say, this power amplifier has only one (set) power amplifier output, and in order to facilitate the connection to the power amplifier output speaker, the "...... you said is setCanon output, two binding post outputs". It can be connected to four speakers.

Hello, I am happy to serve you and give you the following answer: Generally speaking, the back of the integrated amplifier machine is not pre-coarse and reserved for the output of pure amplifier sockets. If you want to output a pure post-amp, you can use the following methods:

1.The output end of the integrated power amplifier is connected to the input terminal of the pure post-amplifier, so that the output signal of the integrated power amplifier can be converted into the input signal of the pure post-amplifier. 2.

The output terminal of the pure amplifier is connected to the speaker, so that the output signal of the pure amplifier can be converted into the input signal of the speaker. Personal tip: When wiring, pay attention to the correctness of the wiring to avoid damage.

In addition, when wiring, it is necessary to pay attention to the compactness of the empty wiring, so as not to affect the transmission effect of the signal.

Hello, I am glad to serve you and give you the following answers: under normal circumstances, the integrated amplifier will not be reserved for the output of pure post-amplifier sockets, but it can also be disassembled by disassembling the internal circuits of the amplifier and decomposing it into pre-amp and post-amp, so as to achieve the purpose of outputting pure post-amp power amplifier sockets. 1.

First, the power amplifier is disassembled to find out the demarcation point between the pre-stage and the post-stage, that is, the connection point between the input and output interfaces of the pre-stage and the post-stage; 2.Then, connect a Sun Chong circuit breaker at the connection point between the pre-amp and the post-amp to disconnect the connection between the pre-amp and the post-amp; 3.Then a regulating controller is connected to the circuit breaker, so that the pre-stage and the post-stage are separated; 4.

Finally, the output end of the circuit breaker is connected to the pure post-amplifier socket, so as to achieve the purpose of outputting the pure post-amplifier socket. The above is the practice step of the integrated power amplifier to output a pure post-amplifier socket, but before disassembling the power amplifier, you need to confirm the internal circuit of the power amplifier to ensure that the normal use of the power amplifier will not be affected after disassembly.

Hello, I am happy to serve you and give you the following answer: Generally speaking, the back of the integrated amplifier is not reserved for the output of pure amplifier sockets. If you want to output a pure post-amp, you can use the following methods:

1.The output terminal of the integrated power amplifier is connected to the input terminal of the pure post-amplifier, so that the output signal of the integrated power amplifier can be converted into the input signal of the pure post-amplifier. 2.

The output terminal of the integrated power amplifier is connected to the output terminal of the pure post-amplifier, so that the output signal of the integrated power amplifier can be converted into the output signal of the pure post-amplifier. 3.The output terminal of the integrated power amplifier is connected to the control terminal of the pure post-amplifier, so that the output signal of the integrated power amplifier can be converted into the control signal of the pure post-amplifier.

When performing the above operations, Zen training should pay attention to the following points:1The voltage between the output terminal of the power amplifier and the input terminal of the pure post-amplifier should be matched to avoid damage to the power amplifier or the pure post-amplifier.

2.The current between the output terminal of the power amplifier and the output terminal of the He-type Weichun post-amplifier should be matched, so as not to damage the power amplifier or the pure post-amplifier. 3.

The signal between the output terminal of the power amplifier and the rental control terminal of the pure post-amplifier should be matched to avoid damage to the power amplifier or the pure post-amplifier. In short, when connecting the output terminal of the integrated power amplifier to the pure post-amplifier, attention should be paid to the matching of voltage, current and signal, so as not to damage the power amplifier or the pure post-amplifier.

Summary. 2 is the hot end (positive electrode), 3 is the cold end (negative electrode), 1 is grounding, so the connection is a balanced connection. 2 is the hot end (positive pole), 3+1 is the cold end (negative pole), so the connection is unbalanced!

That is to say, 2 is connected normally, 3 and 1 are welded together or connected to the negative electrode together.

2 is the hot end (positive electrode) dissipation, 3 is the cold end (negative electrode), 1 is grounding, so the connection is a balanced connection. 2 is the hot end (positive pole), 3+1 is the cold end (negative pole), so the connection is unbalanced! That is to say, 2 is normally connected to the Kai, and 3 and 1 are connected together or together to connect the negative electrode.

Extended Information: Software (Chinese mainland and Hong Kong terminology, called software in Taiwan) is a collection of computer data and instructions that organize the limbs in a specific order.

Generally speaking, software is divided into system software, software for use and middleware in between. Software does not only include computer programs that can be run on a computer (in this case, a computer in a broad sense), but also documents related to these computer programs are generally considered to be part of the software. To put it simply, software is a collection of programs and documents.

In addition, it also refers to the management system, ideological ideology, ideological and political consciousness, laws and regulations in the social structure.
