How to connect a microphone and a red camera?

Usually connected like this:

Micin is connected to the microphone input (pin 1), and micpower is connected to the microphone power supply (pin 3). If you connect it backwards, the microphone will have no input or the volume will be very low.

Must be grounded and connected to (2 feet)

If Mike's cable is not marked with in and power, it can't be connected correctly once. If the microphone does not input or the volume is low after connection, just switch the green line and the yellow line.

However, it must be noted that the fourth pin of the MSI motherboard's front audio interface is used to provide 5V power for the power amplifier, so when connecting the front earphone jack of the ordinary chassis, don't connect any wires at the fourth pin, otherwise it will burn out the motherboard and headphones.

G, grounding

Just connect it to the pins on the motherboard. Check the motherboard manual. If there is sound in the audio output at the back of the chassis, but there is no sound in the front, it may be that you inserted it wrong or not, or there is something wrong with the audio cable of the chassis.

Check it. If the audio cable on the front panel of the chassis is broken, you can buy a two-part audio cable, so that you can connect the speaker and headphones at the same time. Or if you just need to connect headphones but the cable is not long enough, you can buy an audio extension cable.

These two things are bought for more than ten yuan at most, and there are many on Taobao.

Excuse me, how to connect it to the mic socket of the camera?

The camera itself has a microphone with a strong pointing. Since it is the microphone socket of the camera, it is generally the interface for external expansion microphone. The usual specification is 3.5 or 6.5 in diameter. Generally, it is used for a slightly long-distance interview or audio signal transmission and recording. You can also use a wired or wireless microphone receiver to connect the microphone socket of the camera. If the diameter of the socket doesn't match your existing equipment, you can use the adapter plug for conversion!

The camera has no Cannon interface, only one extmic interface. How to connect the mixer?

Extmic is a 3.5mm mini microphone jack, and generally there is a similar 0.5 mm mini audio output jack. Cameras with Cannon interface are generally large cameras, which can provide 48v phantom power for condenser microphones using Cannon interface, while ordinary small cameras do not. But if you are looking for a smaller and simpler camera, it will also have an audio output jack. If found, you can connect the cannon interface with an adapter.

The line output (REC) of the mixer is connected to the microphone input (MIC) of the camera for internal recording. How to solve the problems of broken sound, current sound and sound distortion?

1, rec recording output generally cannot adjust the output level, and the microphone input port of the camera is generally only used for microphone signal input and cannot be used as line input. Because the sensitivity of this input port is quite high. The amplification factor is very large. Generally, if the line signal comes in, it will cause level overload, so there will be sound interruption.

2. There are many possibilities for current noise. First, the connection method is wrong. Second, the line length will cause * * * interference, even because the power supply characteristics of the mixer are not good. So we can't give an accurate answer here.

3. If the camera has line input, the sound will not break when using line input.

4. It is also a good idea to use the aux auxiliary output of the mixer. The level can be controlled. Make the output signal of the camera as small as possible. However, because the background noise of the mixer is constant. So the SNR will change, and the recorded sound will be louder.

5. Make coupling circuit, such as resistance-capacitance control signal size, or use isolation transformer. Both methods can reduce the signal strength and make it match the mic port of the camera. But the isolation transformer is better, which can not only match the signal, but also solve the problem of your current noise.

To which port of the camera is the radio microphone connected?

Photo interview microphone recommendation, photo interview microphone connection guide

1. To confirm whether the camera supports an external microphone, first you need to determine whether your camera supports an external microphone. If not, in other words, if you don't have a microphone interface, it's like cooking without rice, even if you buy it, you can't use it.

2. Confirm whether the microphone input interface of the camera is consistent with the output interface of the external microphone. Secondly, if your machine supports microphone external connection, please see clearly the model of microphone interface supported on the machine. Generally speaking, the commonly used interfaces are 3.5 interface (usually the same size as the earphone hole on PC), 6.35 interface (usually the power amplifier used at home is much larger than the earphone hole on PC), and the other is cannon interface (three pins). If the ports are inconsistent, it can also be solved by purchasing an adapter.
