There are several forms of connection between the loudspeaker and the loudspeaker
Release time:2021-09-14
If it is a home audio system, it is recommended to connect according to the instructions. Of course, when the power of the amplifier allows, the following connection methods can also be used at the same time. Since the output of the loudspeaker contains an output transformer, for ease of use, there are generally low-voltage and high-voltage windings at the secondary end of the output transformer. The low-voltage winding is suitable for direct connection with low-impedance speakers without the need for line transformers Speakers are generally connected in series), but this method is generally only suitable for less than 30 meters, and the line loss increases sharply beyond this distance. The specific calculation formula is: power P = square of voltage / resistance (impedance of the speaker + resistance of the wire) . The high-voltage winding (120V) output is suitable for long-distance broadcasting. At the speaker end, an inter-transformer must be connected first, and the secondary end of the inter-line transformer must be connected to the speaker. The primary ends of all inter-line transformers are connected in parallel with the broadcasting line.
