Sony UTX-B40 Wireless Bodypack Transmitter (941 to 960 MHz)
A compact, all-metal wireless bodypack transmitter, the Sony UTX-B40 stays comfortable to wear and comes with an ECM-V1BMP omnidirectional lavalier microphone.
This one is the 90UC block, tuning 941.625 to 951.875 MHz, 953.000 to 956.125 MHz, and 956.625 to 959.625 MHz. A locking 3.5 mm input keeps the lavalier connected, and it takes other compatible lavaliers and headset microphones as well as a line-level source. RF output switches between 30 mW and 5 mW.
Hold it next to a URX-P40 receiver and NFC SYNC sets the channel, while the URX-P03, URX-P03D, and URX-S03D receivers set it over IR. Auto gain mode looks after the input level, and a +15 dB boost lifts an off-mic voice. Two AA batteries run it for about 8 hours at 30 mW, and a USB Type-C port can power it instead.
