Audio-Technica ATW-D50-DRX-2B 2-Person Wireless Bodypack Audio System, DF2 470-608 MHz

Audio-Technica ATW-D50-DRX-2B 2-Person Wireless Bodypack Audio System, DF2 470-608 MHz

The Audio-Technica ATW-D50-DRX-2B D50 2CH 2BP System is a professional 2-channel digital UHF wireless body-pack system that includes an Audio-Technica LINK-enabled 2-channel receiver and two ATW-DT3201 compact body-pack transmitters. Designed for live sound, broadcast, corporate AV, houses of worship, education, theater, presentation, and installed audio applications, this system delivers flexible wireless performance with secure digital transmission and reliable RF operation. The included half-rack receiver supports advanced system control, while the two compact body-pack transmitters provide a dependable solution for compatible lavalier microphones, headworn microphones, and cables.

The 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 improved RF stability in challenging setups. Up to four receivers can be linked and operated without antenna distribution, requiring only a single pair of antennas. This makes the ATW-D50-DRX-2B a practical choice for multi-channel wireless systems where clean setup, strong signal performance, and efficient rack integration are important.

For congested RF environments, the D50 system offers HD high-density mode, allowing users to expand from the standard 17 usable frequencies within a 6 MHz TV channel block to up to 47 frequencies in HD mode. The ATW-DT3201 body-pack transmitters feature a rugged cH-style screw-down 4-pin input connector, external control buttons, mute switch, OLED status display, and SideTrack function for switching audio to a second output for discrete live communication with performers or audio engineers. Each transmitter is powered by a custom-designed lithium-ion battery and can be charged in the transmitter with an ATW-CHG6 charging station, sold separately, or by removing the battery and charging it separately with the included ATW-CHGA6 battery chargers.
