Microphone plug jack FAQ Have you ever encountered the problem of not being able to insert the microphone plug into your device? PHP editor Baicao introduces a common microphone plug type and its correct insertion method to help you solve this problem. The following content will explain in detail the insertion steps of the 6.5mm microphone plug, guiding you to easily achieve high-quality audio connection.
The 6.5mm microphone plug is usually plugged into a sound input device, such as the microphone input jack of a computer, stereo or mixing console. Plugs of this specification are widely used in consumer electronic equipment and professional audio equipment, and they match the output plugs of microphones or other audio equipment. By inserting a plug into the device's jack, the microphone receives the sound signal from it and sends it to the device for amplification, processing, or storage. The 6.5mm microphone plug is widely used in recording, performance and broadcast fields, providing users with an easy way to connect microphones to various audio equipment.
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 it is a 1

4˝
plug, it is almost all a large 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. 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 asingle jack stereo connection
, such as a headphone port. The second core can only make unbalanced mono connections.If the line is longer, 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
big three-pin
sockets, insert the big two-pin, 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 and the ground are combined, 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 at the large and small core socket The signal is stuck in the rear loop and may not form a signal loop.
The most common plugs are

. 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 silverThere are basically two methods for detecting balanced 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 the balanced and unbalanced input and output parts of most audio electronic equipment are marked with full English names or abbreviated characters, such as: BAL or BALANCED (balanced), UNBAL or UNBALANCED (unbalanced).
Coa is a digital signal processor that can be used for audio processing, but it does not have a direct interface to connect a microphone. To connect a microphone, you need to take additional hardware devices, such as an analog preamplifier or an external audio interface, and connect them to the Coa's input ports. These hardware devices convert the microphone's analog signal into a digital signal and transmit it to Coa for processing. Therefore, although Coa itself cannot directly interface with microphones, it can be used in conjunction with other hardware devices for audio processing purposes.
UHF microphone generally refers to a wireless microphone, which is connected to the receiver through wireless signals to realize the function of wireless transmission of audio signals. Bluetooth is another wireless transmission technology that requires a Bluetooth adapter to connect with other devices. Therefore, UHF microphones generally do not have the function of directly connecting to Bluetooth. However, the Bluetooth connection of the UHF microphone can be achieved by connecting the UHF microphone to a Bluetooth adapter or Bluetooth audio receiver.
Whether the computer host can receive wifi signals has always been a concern for some users. With the development of wireless network technology, more and more users hope to connect to the Internet through WiFi to achieve a more convenient Internet experience. So, can the computer host be connected to wifi? This question involves some basic network knowledge. Let’s discuss it in detail below.
Wifi is a wireless network technology that allows devices to interconnect through wireless signals. Through wifi technology, users can connect to the Internet anytime and anywhere without being restricted by wiring. Generally, we need to use a router to achieve wifi coverage of the home network. For computer hosts, in order to receive wifi signals, a wireless network card needs to be installed on the machine.
Most desktop computer hosts do not come with a wireless network card when leaving the factory, which means that if the user wants the computer host to receive a wifi signal, he or she needs to install it himself Wireless network card. For some laptops, they usually come with their own wireless network card, so they can directly connect to the wifi network.
If your computer host does not have a built-in wireless network card, you can purchase and install an external wireless network card to enable the host to receive WiFi signals. There are many types of wireless network cards, and users can choose the product that suits them according to their needs and budget.
Installing a wireless network card is not complicated. Usually, you only need to insert the wireless network card into a free PCI slot of the computer host, and then install the corresponding driver program. There are different ways to install the driver. You can check the manual of the wireless network card and follow the above steps to configure it.
After the installation is completed, you can search for available wifi networks on the computer host and connect. Remember to maintain network security when using a wifi network and set a password to prevent others from illegally connecting.
When using wifi network, there are some precautions that users need to pay attention to, such as:
Choose a network with strong signal: Try to choose wifi with strong signal network, this can ensure the stability of the network connection. Device location: Try to keep the distance between the device and the router to avoid physical obstacles affecting signal transmission. Network security: Set a wifi password to prevent the network from being illegally connected by others.Through the above introduction, I believe everyone has a better understanding of the issue of whether the computer host can receive wifi signals. As long as your computer host has a wireless network card installed and the configuration is correct, you can easily connect to the wifi network and enjoy the convenience brought by the wireless network.
The aus interface you asked about does not exist. The aux interface is the audio input interface, and the microphone is connected to the microphone input interface. There are 3.5 and 6.5 microphone input interfaces. There are 3.5 and 6.5 microphone cable connectors. If your audio interface is 6.5, you need to use a 6.5 cable connector. If your cable connector is 3.5, you have to use a 6.5 cable connector. Just buy a 6.5 adapter, connect it to the 3.5 connector, and then plug it into the microphone input interface of the speaker.
If you don’t know how to change it, it is recommended not to change it yourself, because it will damage the wiring inside. If you can change it, you can change it
01
Use needle-nose pliers to cut off the damaged parts, including the bad wires and the original plug. As you can see, this plug is wrapped with electrical tape, so it must have been "working while sick."
02
Unscrew the newly purchased welding plug, and put the removed rubber cap directly onto the microphone cable. Special reminder: If you forget to put on the rubber cap, when you finish welding, you will find that your work was in vain.
03
Use needle-nose pliers to peel off the outer sheath of the microphone cable, and then make the ends of the core wire. Please note: The exposed enameled wire must be burned with a match to remove the insulating paint. The burning time should be very short, because the wire is too thin and can easily melt. After burning, the thread should be scraped clean.
04
First, carefully wind the processed thin wire onto the center pole piece, and then solder it with tin. The welding time should not be too long to prevent the plug from burning out; the solder joints should not be too large to prevent internal short circuits.
05
Use the same method to weld the outer ring pole piece. After soldering, pinch the metal card tightly with needle nose pliers. This way the thread is fixed tightly and won't move back and forth.
06
Finally, slide the rubber cap that was previously put on the microphone cable and screw it onto the plug. It's finished, no signs of repairs visible. Plug it into the machine and test it, the effect is very good.
Yes, but the speed is still 2.0. One of my USB 2.0 flash drives has 100 MB read and write when transferring files within 1 GB, and 20 MB read and write after 1 GB.
It can be plugged in, and the transmission speed is based on U-like speed. The speed will be the same only if the configuration of both parties is the same. Therefore, only the transfer speed of the USB flash drive and the computer's socket speed will reach the normal maximum speed.
Can be connected to light strips. There is no specific requirement for the length of the light strip for a socket. It all depends on your power, size, and the current that the socket can handle. The higher the power, the thinner and shorter the strip will be, and the lower the power, the shorter the strip will be. A little longer.
A switch can be connected to the plug line.
1. Prepare the switch and connect two wires from the socket to where you want to set it (if the two wires are black and white wires), if the existing socket has 3 wires ( If it is a black positive pole, a white negative pole, and a red ground wire), connect the white wire of the socket to the newly set white wire.
2. Treat it with insulating tape, and insert the remaining two black wires into the L hole of the switch (the black wire unplugged from the socket) and the L1 hole (the new black wire). Unplug the red ground wire and treat it with insulating tape so that the switch can be used. Please refer to it and don't forget to turn off the power switch.
