The transmitter comes with the KSM9 interchangeable capsule, which has a switchable supercardioid/cardioid polar pattern and captures detailed vocals with decreased proximity effect, so your vocals sound great regardless of mic proximity. With its easy-to-read LCD display, simple control menu, and multiple power options, the ULXD2/KSM9 Handheld Transmitter is a powerful, convenient option for use with your Shure ULX-D2 wireless system.
