How to connect the four wires behind the speaker
During the installation and use of audio equipment, wiring is a critical step. Many users may be confused when faced with the four wires on the back of the speaker. This article will introduce the functions and wiring methods of these four wires in detail, and provide structured data to help you complete the connection easily.
1. Function analysis of the four audio cables
Normally, the four wires at the back of the speaker are divided into two groups, corresponding to the left and right channels respectively. Each set contains two wires: one is positive (usually red or marked "+") and the other is negative (usually black or marked "-"). The following are the specific functions of the four wires:
| Thread color | Function | mark |
|---|---|---|
| red | Right channel positive | R+ |
| black (or white) | Right channel negative | R- |
| white (or red) | Left channel positive | L+ |
| black | Left channel negative pole | L- |
2. Wiring steps
1.Confirm device interface: First, check the interface types of your speakers and audio source devices (such as amplifiers, players, etc.) to make sure they match.
2.Distinguish between positive and negative poles: According to the markings in the above table, distinguish the positive and negative poles of each wire. The positive terminal is usually red or white, and the negative terminal is usually black.
3.Connect left and right channels: Connect the positive terminal (R+) of the right channel to the positive terminal of the right channel of the audio source device, and the negative terminal (R-) of the right channel to the corresponding negative terminal. The left channel is connected the same way.
4.Check connection: Make sure all interfaces are firmly connected to avoid looseness leading to poor contact.
3. Common problems and solutions
| question | Possible reasons | Solution |
|---|---|---|
| The speaker is silent | Wrong wiring or poor contact | Recheck the wiring to make sure the positive and negative poles are connected correctly |
| sound distortion | Positive and negative poles reversed | Swap the positive and negative wiring |
| Mono only | A channel is not connected | Check whether the left and right channel wiring is complete |
4. Precautions
1. Before wiring, be sure to turn off the power of all devices to avoid short circuit or damage to the equipment.
2. If your audio cable does not have color markings, you can distinguish the positive and negative poles by checking the audio manual or using a multimeter to measure.
3. For high-power audio systems, it is recommended to use better quality wires to reduce signal loss and interference.
4. If you are not familiar with wiring operations, it is recommended to seek professional help to avoid damage to the equipment.
5. Summary
The wiring of the four wires behind the speaker is not complicated. You just need to correctly distinguish the positive and negative poles and the left and right channels and follow the steps to complete it. This article provides detailed functional analysis and wiring steps, and lists solutions to common problems, hoping to help you successfully connect your speakers. If you encounter other problems during operation, you can refer to the equipment manual or consult a professional.
Through the above steps, you can easily solve the problem of audio wiring and enjoy a high-quality music experience.
