Sennheiser understands that the more self-reliant a device is, the more artistic freedom there is to enjoy. With this in mind, this new receiver has a built-in Ethernet port for remote PC monitoring and setup with Sennheiser's Wireless System Manager software. This receiver's wireless sync function makes it a breeze to link up any G3 transmitter with the unit. In addition, it has a large backlit graphic display where receiver and transmitter information can be easily seen even on the darkest of stages.
