Sony UWP-D22 Camera-Mount Wireless Handheld Microphone Kit with Digital MI Shoe Adapter (UC14: 470 to 542 MHz)

Yes. You have a few options for adding a lavalier microphone to the Sony UWP-D22 Camera-Mount Wireless Cardioid Handheld Microphone System - UC14: 470 to 542 MHz. The first option is to use an additional complete wireless lavalier system such as the Sony UWP-D21 Camera-Mount Wireless Omni Lavalier Microphone System - UC14: 470 to 542 MHz (B&H # SOUWPD2114). If you are using a separate wireless mic system, you can use the same frequency band or a different band since the two systems will be independent. Another option is to replace your existing single-channel receiver with the Sony URX-P41D Dual-Channel Camera-Mount Wireless Receiver - UC14: 470 to 542 MHz (B&H # SOURXP41D14) which will allow you to use two transmitters simultaneously with the same receiver, and purchase the Sony UTX-B40 Wireless Bodypack Transmitter with Omni Lavalier Mic - UC14: 470 to 542 MHz (B&H # SOUTXB4014) to use together with your existing Sony UTX-M40 Wireless Handheld Cardioid Microphone Transmitter from the UWP-D22 System. If you do want to use two transmitters simultaneously with the URX-P41D Dual-Channel Receiver, make sure that all components operate on the same frequency band.
