When wireless performance needs to scale without adding unnecessary complexity to the rack, a flexible receiver can make the entire system easier to deploy and manage. The Audio-Technica ATW-DR3220LKDF2 2-channel digital wireless receiver for the D50 digital UHF wireless system combines wideband operation, switchable RF modes and Audio-Technica LINK connectivity in a compact half-rack platform built for professional live sound, touring, houses of worship, corporate AV and installed systems. Its broad 470.125–607.875MHz DF2 tuning range provides flexibility for frequency coordination, while 48kHz digital audio delivers a 20Hz–20kHz response, up to 120dB of dynamic range and AES-256 encryption. Low-latency operation, High Density capability, onboard DSP and AC or PoE+ power further equip the ATW-DR3220LKDF2 for demanding wireless environments where reliability and efficient system management are essential.
Flexible RF Modes Adapt to Challenging Environments
Two selectable RF modes allow engineers to optimize the receiver for the requirements of each deployment. Normal mode uses Antenna Combining Diversity for efficient everyday operation, while Robust mode employs MRC True Diversity for enhanced RF stability when conditions become more challenging. Standard mode supports up to 17 frequencies within a 6MHz TV channel with typical latency of 2.1 ms, while High Density mode increases capacity to as many as 47 frequencies within the same bandwidth with 3.3 ms typical latency. Up to four compatible D50 receivers can also share a single pair of antennas without requiring separate antenna distribution hardware, helping streamline larger wireless installations.
LINK Networking and DSP Streamline System Control
Audio-Technica LINK and 100 Mbps IP connectivity provide a foundation for centralized system management, allowing the receiver to integrate into compatible networked Audio-Technica environments and support configuration and monitoring through Audio-Technica Wireless Manager software. Onboard DSP provides a high-pass filter, four-band EQ and compression for direct signal shaping within the receiver, while AES-256 encryption helps protect wireless audio in privacy-sensitive applications. BNC antenna connections with 12V DC antenna power further support integration into professional RF systems.
Flexible Power Supports Professional Installation
The ATW-DR3220LKDF2 can operate from its included AC adapter or IEEE 802.3at Class 4 PoE+, allowing network power to serve as an alternative source or provide redundant backup when AC is connected. Its rugged metal half-rack chassis measures 8.3" wide by 11.3" deep by 1.7" high and weighs approximately 4.6 lb. without accessories, making it practical for both portable racks and permanent installations. Fan-assisted cooling, included rackmount hardware and professional antenna connectivity complete the Audio-Technica ATW-DR3220LKDF2 2-channel digital wireless receiver, a scalable D50 solution for individual systems and larger coordinated deployments.
