This is a set consisting of a bodypack transmitter (UTX-B40) and a portable diversity tuner (URX-P40). When combined with a small camcorder, it allows for a mobile system in ENG and EFP applications. I used this professionally for a year. No box. Missing items. Everything in the photos is included. Includes three pin microphone windscreens. The transmitter can be used exclusively with pin microphones. CD-ROM and a cable for a handheld microphone are missing. I used this for program production with Sony α series and Canon EOS series cameras. ● High-quality sound achieved through Sony's digital audio processing technology ● NFC SYNC function for quick, easy, and secure channel settings ● True diversity reception system for stable signal reception ● Auto gain mode that eliminates the need for volume adjustment ● +15dB gain boost mode to increase volume when using off-mic ● Line input compatible (transmitter: UTX-B40) ● Channel memory function for quickly switching between two frequencies on the receiver ● Transmitter frequency can be transmitted to the receiver (transmitter: UTX-B40) ● Headphone output terminal for monitoring (receiver: URX-P40) ● Monitor mode, convenient when using the receiver as an in-ear monitor (receiver: URX-P40) ● Mute function with various settings (transmitter: UTX-B40) ● Compatibility with Sony WL-800/UWP/UWP-D series ● Output level adjustment function on the receiver (receiver: URX-P40) ● Easy-to-see organic EL display even outdoors (transmitter: UTX-B40 / receiver: URX-P40) ● USB terminal for external power supply (transmitter: UTX-B40 / receiver: URX-P40) ● Human sensor mode (transmitter: UTX-B40) ● Compatibility with previous models via infrared communication function (transmitter: UTX-B40) ● Compact and lightweight design ensures high mobility ● Compatible with digital audio interface when combined with the optional Multi Interface Shoe Adapter SMAD-P5 #PinMic #ProfessionalUse #ProfessionalMicrophone #WirelessMicrophone
