1. Where is the Dongfeng Fengshen computer link plug?

The computer plug is on the left side of the fuse box on the lower left side of the steering wheel. Some are on the right and some are under the left air outlet.

2. What is the function of the 6.3mm large three-core plug?

There are three types, 6.35mm large two-core TS, large three-core TRS, and XLR (there is also a small three-core 3.5mm interface, which generally refers to a stereo two-channel interface, generally used for headphones and speakers) Computer interface)

In many audio system applications, it is often found that as long as the 1

/

4

˝

plug is almost the same as the big two core, resulting in a lot of balance The traditional circuit design has lost its meaning of existence, and as a result, many friends have fallen into endless troubles with noise.

In professional audio systems, try to use TRS connectors as uniformly as possible. Although not all devices have balanced inputs and outputs, they can all be connected using XLR and TRS connectors. . You can remember one sentence: the big three core can replace the big two core, but the big two core cannot replace the big three core (the INSERT breakpoint access interface must use the big three core). The main purpose is to use balanced line noise suppression design as much as possible to minimize the background noise caused by external interference (mainly from: electromagnetic field interference). In addition, the more professional microphone interface is the XLR port, which is used for professional microphones or professional recording equipment. It has the best anti-interference and electrical performance, and the interface is tighter.

6.35TS is an unbalanced line. It is generally used in homes. It has two sections. It is commonly known as a large two-core cable. It has poor anti-shielding and has little impact from short lines. It is used for the transmission of monophonic signals and has a shape similar to that of a large two-core cable. Three-core, but one less ring than the big three-core. It can be converted directly through core-to-core, shield-to-shield welding and RCA, BNC and other mono connectors for mono. It can only transmit

Unbalanced

signal.

6.35TRS is a balanced line, used in professional equipment. It has three sections, commonly known as large three-core. It has better electrical performance, strong anti-interference effect (mainly depends on the material and technology of the wrapped wire), and the reliability of the joint higher. The

big triplex

can be used for a mono balanced connection, such as the LINE input port of a mixer; it can also be used for a

single jack stereo connection

, such as a headphone port. The second core can only make mono unbalanced connections.

If the line is long, it is recommended to use a balanced line. If the 6.35 interface wants to produce stereo sound, it usually has two channels, L and R. If it does not produce stereo sound, only one interface will do. As for whether to use the second-largest core or the third-largest core, it depends on what interface the device provides. If the input and output of the device are both

Big 2-core

sockets, then using a 2-core or 3-core is the same. The middle ring of the 3-core is suspended, and the signal goes through the head ring and rear ring.

If the input and output of the device are both

large three-core

sockets, insert the large two-core, the middle ring and the rear ring are merged (signal and ground are merged), and the sound will also sound. The interference immunity of balanced connections is lost. Under household conditions, this approach is not a big problem, because the anti-interference advantage of balanced connections is not obvious under household conditions.

If the device has a three-pin socket on one end and a two-pin socket on the other. If both large and small cores are used, the signal at the three-core end is combined with the ground, and the sound will also sound; if both large and small cores are used, the signal at the large and small three-core socket is stuck in the middle ring, and the signal at the large and small three-core socket is stuck. The signal is stuck in the rear loop and may not form a signal loop.

The most common plugs are

silver white

and

copper yellow

. The silver one is copper plated with silver, and the copper yellow one is copper. Since the stability and electronic engineering of silver are better than those of copper, the user experience of using the plug device can be upgraded after copper is plated with silver

There are basically two detection methods for balanced output:

1. Voltage detection method: First input a music signal or sine wave signal. For a 6

For XLR sockets, you can directly measure pin 3 and pin 1, and the judgment method is the same.

2. Impedance detection method: For a 6

If there is an impedance reading, it is a balanced output. If the impedance A reading of 0 indicates an unbalanced output. For XLR sockets, you can directly measure pin 3 and pin 1, and the judgment method is the same. This method is also applicable to the detection of signal input interfaces of audio equipment.

Usually on most audio electronic equipment, the balanced and unbalanced input and output parts are marked with full English names or abbreviated characters, such as: BAL or BALANCED (balanced), UNBAL or UNBALANCED (unbalanced).
