Talk about lotus threading.

First,? Ordinary balanced signal plug:

Answer: the cannon plug (XLR): the cannon head is divided into the cannon head (XLR? Male) and cannon (XLR? It is very simple to distinguish the male and female of the gun head. Those with needles are male heads, and those with holes are female heads. The input and output ports of many audio equipment are cannon interfaces, the interface with "pin" is the male seat, and the interface with "hole" is the female seat.

B, is it? Big three-core plug or 6.3mm three-core plug (PhoneJack? Balance)

Second,? Common unbalanced signal plugs:

A: Dual-core plug (PhoneJack? Imbalance? )。 ?

B, is it? Lotus plug (RCA)

C. Three-core plug or 3.5mm three-core plug

The appearance of the small three-core plug is similar to that of the large three-core plug, but the volume is smaller than that of the large three-core plug. The three-core plug is a three-core plug. As mentioned above, the three-core plug is a balanced signal plug, but in the usual audio engineering, the three-core plug is mostly used for computers and portable audio sources (portable CD? /? MP3 and so on. ), so the three-core plug is classified as unbalanced signal plug.

Third,? Neutrik speaker plug (Speakon):

Neutrik plugs commonly use four-core, two-core and eight-core speaker plugs. They are basically the same in appearance, but different in size. Under normal circumstances, the interface of the speaker is a four-core plug. If it is an eight-core plug, there will be a mark on the back of the speaker. The output port of the power amplifier is a four-core plug.

Fourth,? Common video connection plugs:

Lotus plug is mainly used for analog video signal output and input in video system, such as video (image) output of DVD player/video (image) input of small projector;

Shower head audio line is a kind of audio line. Lotus interface RCA connector, commonly known as Lotus Line, is suitable for connecting vcd, dvd, TV, tape recorder, cd and so on. And transmit their audio signals. Widely used in recording studios, stage acoustics and video and audio systems.

An audio and video cable, the connector is called "Lotus Head" or "Lotus Plug" (English RCA connector) because it looks like a lotus.

RCA connectors are not specially designed for any kind of interface, and can be used to transmit audio, ordinary video signals and DVD components (YCrCb or YPbPr), but the number is three.
