The join of sound system has a lot of kinds, different system and equipment have different join method. But substantially principle is same, still basically have: Phonic source work puts a horn, of composition.
1, present phonic source includes all sorts of musical instrument, all sorts of phonic source players reach a few special sound generator.
2, result putting is to all sorts of enlarge circuit are comprised, the signal of the class before can be opposite undertakes enlarge, the horn of the class after drive.
3, combine many horns together commonly now, form sound box, also formed the sound box of a lot of sort.
Above is system of the simplest a sound. A lot of auxiliary equipment were added again in present system of course, we are called: Besmear of an ancient nationality in China of manganese of A Chinese-style unlined garment of account of the collect before Kang of word of show off of heart of a key to do sth of cheek of N of float of uncut jade of Gu of a drum used in the army in ancient China sincering feeling dash forward Li of Huang of gadolinium of the She nationality of hazel of exhaust jab of У bursa illuminate low cook over a slow fire of Li of bursa of of of of ㄋ of any of several hot spice plants of Yong of of herd of of brilliant of Fu of Na Pu of of of constant ?
The commonly used jumper in sound system and receive plug-in unit
Contact should be reached to transmit between the equipment in sound system and equipment, communicate etc, must admire the tool that Lai Jilian receives, this is wire and connect. It is holding very important role in whole sound system, the jumper that uses in system of professional now sound and receive plug-in unit sort more, below we a common wire and receive plug-in unit sort to make simple introduction:
One, all sorts of wire
1, professional frequency line: Frequency line has two core, 3 core, 4 core, 5 core to wait now, this kind of line is fine as a result of screen effect, can use the frequency signal of transmission high quality; More professional now mike uses the wire of 3 core above commonly, capability of interference rejection of this kind of wire is strong, can do remote deferent. Of course this kind of wire is OK also and deferent other signal, if pass the DMX512 of lamp of power transmission head,control signal.
2, coaxial cable: Use in video respect commonly, also have line of a few frequency, because ability of interference rejection of this kind of wire is poorer, plus not be to basically use transmission frequency signal when the design, the frequency signal that does not suit to make Sunday run accordingly is transmitted.
3, cable of collect Chinese style ∶ is line of many question mark wrap up is in same inside protective canal, it is to join systematic interior is used commonly, in order to reduce the amount of independent wire. Also use in car of such as television relay, underground to be buried beforehand now with other special respect. This kind of line has professional manufacturer to had been machined commonly, there is safeguard relatively on quality.
