Q: Why are XLR series connectors the choice for professional microphones?

A: The XLR series supports balanced audio transmission (transmitting positive phase signals, negative phase signals and ground via 3 pins separately) with a signal-to-noise ratio of ≥80dB, which can resist electromagnetic interference from stage lighting (dimmers) and audio equipment to avoid noise. It also adopts a snap-lock design to prevent accidental disconnection of microphone cables (ordinary RCA connectors are prone to loosening), making it suitable for high-demand scenarios such as concerts and live streams, with a mating life of ≥5000 cycles.
