The Sony URX-P03D Dual channel Transmitter Set is a transmitter set that allows you to record two sources simultaneously on two different channels. For this, you only need one receiver that can be mounted on the camera via the camera's hot shoe adapter mount. 

The transmitter set offers a wide frequency range with a bandwidth of up to 72 MHz and consists of two transmitters, one receiver and two lavalier microphones. Thanks to various features such as Clear Channel Scan, Active Channel Scan and IR Sync, the set searches for an empty channel and automatically finds the best option. 

Furthermore, it has a headphone output and a USB connection. 

Finally the dimensions of the receiver are 63mm x 82mm x 28.4mm and it weighs 210 g. 

Please note: This set only works with the included COS11D-UWP Lavalier Microphones with Sony UWP plug. You cannot use the set with a regular COS11D microphone without the Sony UWP plug.
