Today, I will introduce you to the relevant knowledge about fast fish pickups. People are still familiar with the pickups. The pickups are also called monitor heads. They are a kind of equipment that sends sounds around the scene to the back-end equipment. The pickup has many advantages such as high power, low sustain and noise. However, the performance of the body and wood is not very good. So, how do you connect the fast fish pickups that we can often see in our daily life? Here I will take the fast fish N.TRADIO anti-echo pickup as an example to explain the relevant knowledge about how to connect the fast fish pickups .

Fast fish pickup model

Fast fish pickup model HTRADIO is also good, can clearly monitor the angle of 45 degrees, within 30 meters of the incident. It uses two complementary high-sensitivity microphones to pick up a wider audio band and wider range. One of the ultra-sensitive high-resolution directional microphones specifically monitors far-end narrow-angle sound sources, and the second-time high-sensitivity weak directional microphone monitors wide-angle sound sources. The organic fit of the two not only greatly expands the “view” of the monitoring, but also greatly expands the sound range, and the sound of monitoring is more clear and rich.

How to fast fish pickup wiring

Acoustic audio signal cable and audio ground cable can be directly connected to the device: Acoustic headphones, active speakers, audio amplifier, audio and video distributor, DVR DVR, video server, mixer, recorder, sound card or other audio equipment LineIn linear input (microphone connection is strictly prohibited).

(1), hard disk recorders. Most hard disk video recorders have corresponding audio input ports, which are generally coaxial cable BNC plugs. The pickup audio cable needs to be connected to the center pin position of the BNC plug. The pickup must be connected to the shell of the BNC plug (that is, the shielded copper mesh connecting the coaxial cable).

(2) Powered active speakers. A set of ordinary active speakers are generally left and right, corresponding to the left and right audio channels, respectively. This pickup only provides one sound source, so it is a "mono" sound source. The audio cable of the pickup is connected to the left/right audio line of the speaker cable, and the pickup is connected to the ground line of the speaker cable in common.

(3) Other methods of connecting audio equipment such as power amplifiers and mixing consoles are the same as those described above.

(4) It is forbidden to connect the pickups to the microphone (MIC) input terminals of sound cards, mixers, amplifiers, etc., otherwise the equipment may be damaged. This is because the microphone inside contains a microphone, but it also includes amplification, noise reduction, echo processing and other circuits, output "LineOut" audio signal above 1Vpp.

(5) Notebook computers are seldom equipped with "LineIn" audio input jacks, generally only equipped with MIC input jacks and SPEAKER output jacks. The pickup cannot be directly connected to the MIC port. Only a professional external USB interface desktop sound card can be purchased. Use the “LineIn” port to access it.

(6) The pickup audio cable cannot be directly connected to the two audio devices. The pickup adapter must be connected to avoid deterioration of the sound quality due to impedance mismatch.

Editor's summary: There are two types of active and passive pickups. When installing the pickups, remember that the installation location is centered on the main conversation area. In this case, the effect of pickup is best, if it needs to be installed on the ceiling or the wall. On the surface, try to install a concealed wall as much as possible so that it will not affect the beauty of the wall and achieve a good pickup effect. It can be said to serve two purposes. The wiring method of the pickups is explained to everyone here. Hopefully, More or less can give you a little help.
