Sizheng pickup teaches you how to distinguish between microphones and microphones
The pickup, also known as a pickup, is a pickup accessory for simultaneous recording and video surveillance. Graphically speaking: The camera is the eye and the pickup is the ear. DVRs, network video servers, etc. are responsible for the digital transmission and storage of sounds and images. Monitors and speakers are used for playback. It can be said that video without a pickup is like a silent movie. The microphone integrates advanced noise processing, echo processing, and long-distance transmission drive circuits to meet higher standards and special needs of security projects, faithfully recording and restoring the scene with its high-fidelity sound quality.
A microphone (also simply referred to as a microphone) is simply a transducer that converts sound into electronic signals. Then the main difference between the pickup and the microphone is there. Here's a brief description of the difference between the two, you understand the real reason.
The pickups are designed for high sensitivity, omnidirectionality, and integrated preamplifier circuitry. Therefore, the monitor head can be directly connected to the DVR, the active speaker, the earphone, etc. can directly release the collected sound, and the microphone also needs to connect the amplifier, because the ordinary microphone is usually oriented and low-sensitive, in close proximity Aligned to speak.
On the hardware side, pickups have added a voltage regulator circuit, a frequency selective circuit, and a front audio amplification stage to the microphone. That's why the pickup requires input power.
In terms of range, the microphone can only expand the receiving range by increasing the sensitivity; and the pickup can expand the monitoring range by adjusting the power consumption and gain of the product, which allows the pickup to have a great advantage in the adjustment range.
The difference between Linein and Micin and the use of our computer sound card, there will usually be Linein and Micin two interfaces, translated into Chinese is "linear input" and "microphone input", these two are input ports, but there are still differences :
1. Linein port: This port is mainly used for recording audio signals output from external devices such as electric guitars, keyboards, and synthesizers. Since the output power of these devices is relatively large, they need to be connected to the Linein port for recording. Of course, they are used for recording. To a certain extent, it can also be called "inside recording" of external devices. The better you use the sound card, the lower the noise in the Linein, and the better the recording effect.
2, Micin port: This should be used to connect microphone recordings. But the difference between this port and Linein is that it has a preamplifier. In other words, the microphone itself has low output power, so an external amplification device must be used to amplify the audio signal. This port is playing this role. Interested friends can try to connect your microphone directly to the Linein port recording... no sound or very small sound right? ! The reason is simple: the microphone signal is not amplified and the natural effect is not good.
3. The special point to be emphasized is that external audio equipment such as electric guitars and synthesizers must not be directly connected to the Micin recording. Because this connection is light, the signal will be severely shaved during recording, and the audio card will be damaged. hardware equipment!
