The XS Wireless IEM transmitter features metal housing designed for durability and can be rack-mounted system or used stand-alone. The clear, backlit menu allows for easy setups even on dark stages. The XLR combo inputs provide flexible cabling options – you can connect anything with a XLR or 6.3 mm (1/4 inch) plug. You can 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.
