When two presenters, performers or speakers need to move naturally without sacrificing vocal clarity, a coordinated dual-lavalier system keeps the production flexible and unobtrusive. The Audio-Technica ATW-D50-DRX-2BL 2-channel wireless system combines a LINK-enabled ATW-DR3220LK dual-channel receiver with two compact ATW-DT3201 body-pack transmitters and two AT831cH cardioid condenser lavalier microphones. Operating across the 470.125–607.875MHz UHF range, the system delivers 48kHz digital audio, up to 120dB of dynamic range and AES-256 encryption with an operating range up to 328'. Switchable RF modes, High Density operation, network connectivity and rechargeable transmitters make it a complete professional solution for corporate AV, houses of worship, theater, education and other productions requiring two discreet hands-free wireless channels.

Flexible RF Modes Adapt to Challenging Environments

The half-rack ATW-DR3220LK receiver offers two selectable RF operating modes to match the demands of each deployment. Normal mode uses Antenna Combining Diversity for efficient everyday operation, while Robust mode employs MRC True Diversity for increased RF stability in more challenging environments. Standard operation supports up to 17 frequencies within a 6MHz TV channel with typical latency of 2.1 ms, while High Density mode expands capacity to as many as 47 frequencies in the same bandwidth with 3.3 ms typical latency. Up to four receivers can also be linked and operated from a single pair of antennas without requiring a separate antenna distribution system, simplifying higher-channel-count installations.

Dual Lavalier Microphones Deliver Focused Voice Pickup

Two included AT831cH cardioid condenser lavalier microphones provide crisp, full-sounding voice reproduction while offering strong gain before feedback and effective suppression of unwanted background sound. Each microphone delivers a 40Hz–16kHz frequency response, 112dB dynamic range and maximum SPL of 141dB, providing the headroom required for a wide range of speaking and performance applications. Their compact design remains discreet when clipped to clothing, while the included windscreens and clothing clips make both channels ready for professional presentation, theatrical and spoken-word use.

Compact Body-Packs Add Control and Communication

Each ATW-DT3201 body-pack combines a durable metal enclosure with a secure cH-style screw-down 4-pin input connector that helps keep the included lavalier firmly connected during use. External controls and an OLED display provide convenient access to transmitter status and settings, while IR synchronization streamlines pairing with the receiver. SideTrack functionality allows audio to be switched to a second output for discreet communication with fellow performers or audio engineers, and a 120Hz high-pass filter helps control unwanted low-frequency information. Selectable 1, 10 and 20mW RF output in Standard mode provides additional flexibility for different wireless deployments.

LINK Networking Simplifies Professional System Management

Audio-Technica LINK connectivity and 100 Mbps IP control make the ATW-DR3220LK well suited to sophisticated installed and production environments, while onboard DSP provides high-pass filtering, four-band EQ and compression directly within the receiver. Power can come from the included AC adapter or IEEE 802.3at Class 4 PoE+, with PoE+ also available as a redundant backup source. BNC antenna connections, antenna power and rackmount capability allow the receiver to integrate cleanly into portable systems, equipment racks and permanent installations.

Rechargeable Power Supports Extended Productions

Each ATW-DT3201 uses a custom LI-220 rechargeable lithium-ion battery with 2,200mAh capacity, providing up to approximately 12 hours of operation at 10mW for long presentations, performances and production days. Batteries can be charged while installed in the transmitters with the optional ATW-CHG6 two-bay charging station or removed and charged separately with the included ATW-CHGA6 external battery charger. Complete with two body-pack transmitters, two AT831cH lavaliers, rechargeable batteries, windscreens, clothing clips, receiver antennas, AC adapter and rackmount hardware, the Audio-Technica ATW-D50-DRX-2BL 2-channel digital wireless system provides a complete professional lavalier solution for clear voice reproduction, reliable RF performance and scalable deployment.
