From Manufacturer
The 470 to 542 MHz version of the Sony UTX-M03 Handheld Wireless Microphone with Cardioid Capsule features an all-metal chassis, an easy to read LCD display, a wide switching RF bandwidth, USB power and charging options, automatic channel scanning, infrared synchronization between the transmitter and receiver, and digital companding circuitry to improve the transient response of received audio.
