First of all, we should observe the output mode of the backplane with power amplifier, and adopt the corresponding connection mode according to the design mode of the terminal.

Some speakers use wire pressing terminals, nut wire pressing terminals, banana head socket terminals, lotus socket terminals, Y-type fastening terminals, O-type fastening terminals, four-core socket terminals, eight-core socket terminals and so on;

Because there are many types of terminals and different welding methods, the two most common connection methods are introduced first, and other connection methods are shown in pictures. Common small speaker wire crimping is to peel off two wires of the speaker for about 2CM, cut the ends of the wires in half with scissors, and then press the red wire into the red jack of the terminal; Press the black wire into the black socket in the same way and press it tightly;

If the nut is pressed directly, the threaded end can be wound around between the screw and the nut, and the nut can be rotated and tightened. When connecting, the red line must correspond to the red terminal; The black line corresponds to the black terminal;

Other speaker cables are connected to the conversion head as shown in the following figure:

The picture above indicates the common connection modes of the speaker plugs for civil and professional use, and also indicates the conversion modes of the speaker plugs and plugs. As long as you follow the welding method and conversion method in the drawing, you can complete the connection including civil and professional speaker lines.

Note: the speaker needs a power amplifier to restore sound, so the speaker can only be connected to the equipment with a power amplifier circuit, and cannot be directly connected to the sound source equipment, otherwise the purpose of amplifying and restoring sound cannot be achieved.
