Hiding underneath the sturdy 19-inch metal housing of the stationary receiver is highly advanced professional transmission technology. As with all components of the 2000 series, with the EM 2000 you can use five windows of up to 75 MHz in the UHF range. 20 channel bands with up to 64 presets and 6 channel bands each with up to 64 user-programmable channels are available. Each transmitter can be synchronized quickly and easily using infrared. The transmitter can be connected to networks via its Ethernet socket and can be monitored and controlled remotely from the PC using the Sennheiser Wireless System Manager software.
