A UHF transmitter that is durable and allows for easy setups anywhere, including dark stages.

The SCW IEM stereo transmitter from Sennheiser is a single, half-rack stereo UHF transmitter with rugged metal housing. As a part of the XS Wireless IEM series, compatible with both Band A and Band B, the XS Wireless IEM transmitter is designed for durability and can be used as part of a rack-mounted system or stand-alone. The clear, backlit menu allows for easy setups even on dark stages. The XLR combo inputs provide flexible cabling options, allowing you to connect anything with an XLR or 0.25-inch plug. You can also preview your in-ear mix locally with the headphone output on the front. Setting up gain, mono or stereo options, input sensitivity or frequency channels takes just a matter of seconds thanks to the clear, simple menu.
