The Sony UTX-B03 Wireless Bodypack Transmitter fulfills the audio requirements during live or recorded event coverage. A lavalier microphone provided with the transmitter. You can use this transmitter with UWP or WL-800 series receivers. The digital companding uses analog-to-digital and digital-to-analog conversion steps to reduce the signal to noise ratio. The transmitter conducts an auto scan for the active transmission channels to synchronize them with the receiver. You can switch between the microphone and line-level input sources anytime. The UHF Phase Locked Loop synthesized frequencies stabilize the transmission and reception process. A pilot-tone is transmitted to keep RF interference in check. This Sony transmitter saves interference-free transmission frequencies into the internal memory to speed-up the setup process and audio group switching. The RF output offers two options: 5mW for indoor and 30mW for outdoor. The bright LED screen shows the channel and frequency status, battery life, usage time, and more. For durable performance, the transmitter is shielded in an all-metal construction.
