This is a three-wire connection terminals, three wires are positive, negative and shield. XLR is called "balanced terminal" and "microphone plug" terminal wiring, in general use in the professional or broadcast television terminals installed, but in some of the more top home audio equipment is also used to, and after the first stage amplifier stage signal transmission between the amplifier. Advantages balanced XLR terminals that transmit signal linearity, which can greatly reduce the electromagnetic, radio frequency interference with electronic systems at work at the time of long-distance transmission of audio signals and noise and hum and terminals generated in the audio signal are essentially different. Fuse terminals: For some special cases in circuit protection, the value of an instrument or device is immeasurable terminal price, due to the instability caused by the loss of current and voltage is very unwise, so in this case you need to There may be a protective device circuit. When the current is too large will automatically disconnect the circuit, which fuse terminal design out. Typically market commonly used specifications for UK5-HESI, UK10-DREHSI and ASK1EN so on. Double terminals: the demand for space design, requiring a small space by more than two cable terminals, which designed the double terminals, common specifications UKK5, UKK3, MBKKB2.5 so on. Products always follow the market, adapt to the market.
