Audio-Technica ATW-D50-DRX-2BL 2-Person Wireless Cardioid Lavalier Microphone System, DF2 470-608 MHz

Audio-Technica ATW-D50-DRX-2BL 2-Person Wireless Cardioid Lavalier Microphone System, DF2 470-608 MHz

The Audio-Technica ATW-D50-DRX-2BL D50 2CH 2BPL System is a professional 2-channel digital UHF wireless body-pack system with lavalier microphones, designed for clear voice pickup, secure wireless transmission, and flexible system control. This system includes an Audio-Technica LINK-enabled 2-channel half-rack receiver, two ATW-DT3201 compact body-pack transmitters, and two AT831cH wireless clip-on lavalier microphones. It is ideal for live sound, broadcast, worship, education, corporate presentations, theater, conference systems, and installed AV applications that require dependable wireless lavalier microphone performance.

The included half-rack receiver operates in two switchable RF modes to support different wireless environments. Normal mode uses Antenna Combining Diversity, while robust mode uses MRC True Diversity for greater RF stability in challenging conditions. Up to four receivers can be linked and operated without antenna distribution, requiring only a single pair of antennas. This helps simplify multi-channel wireless setups while maintaining professional RF reliability and system flexibility.

The D50 system also supports HD high-density mode, expanding the number of usable frequencies from the standard 17 frequencies within a 6 MHz TV channel block to 47 frequencies in HD mode, which is especially useful in congested RF environments. The ATW-DT3201 body-pack transmitters feature rugged cH-style screw-down 4-pin input connectors, external control buttons, mute switches, OLED displays, IR sync, all-metal construction, and SideTrack functionality for switching audio to a second output. The included AT831cH wireless clip-on lavalier microphones provide crisp, full-sounding voice pickup with excellent gain before feedback and suppression of background noise.
