The transmitter comes with the KSM9 interchangeable capsule, which has a switchable hypercardioid/subcardioid polar pattern and captures detailed vocals with decreased proximity effect, so your vocals sound good regardless of mic proximity. With its easy-to-read LCD display, simple control menu, and multiple power options, the QLXD2/KSM9HS handheld transmitter is a powerful, convenient option for use with your Shure QLX-D2 Wireless system.
