The Sony UTX-P40 Digital Wireless Plug-On Transmitter (638-694MHz) is a wireless plug-on transmitter compatible with the URX-P40 camera-mount receiver. Compact and lightweight, with a robust, all-metal construction, this plug-on is well suited for tough operating conditions. It provides up to 6 hours of operation on two AA batteries, with a selectable 5/40mW RF power output and a transmission range up to 100 meters. The UTX-P40 can be attached to a handheld microphone of your choice for man-on-the-street interviews, or to a shotgun mic for wireless booming (both types of mics are available separately). The plug-on provides 48V phantom power, giving you the option to use a condenser microphone. The transmitter offers a 72 MHz bandwidth with 2772 selectable UHF frequencies.
