Combo XLR/P10
At the 1964 Winter Olympics in Innsbruck, the Tyrolean acoustics engineer Bernhard Weingartner noticed that the sound tended to decrease. The reason for this was that the DIN audio connectors used by Austrian television failed under the influence of bad weather. . Weingartner began in 1974, initially on his own, with the development of an inexpensive but high-quality version of the XLR connector.  Over the following years, the Neutrik company became the world leader in the XLR audio connector market. Neutrik connectors have been standardized to the stage and studio standard as standard IEC 61076-2-103.
