This 3-pole XLR female Viborg CM201(R) XLR base has an exemplary design thanks to the use of the best materials. Indeed, the contacts of the base plate are made of 99.998% pure Copper to ensure an excellent conductivity of the audio signal. Contacts that also benefit from a double silver and rhodium plating. Silver being the best conductor, it allows to maximize the transmission performance of the base plate, where Rhodium will protect the contacts from corrosion and thus considerably extend its life span.
