This single distributor makes it possible to split the audio signal in bone-and air conduction, in order to regulate the different signals and to connect a therapy headphone by a 5 pol.XLR plug. All plug connections are gold plated. The connection to the DEEAdvanced-system is possible using a 6,3mm or 3,5mm jack plug. The single distributor is perfect for mobile use (please refer to mobile version 1)
