ATW-DR3220LKDF2

Dual-Channel Reception
Handles two wireless audio channels in a compact half-rack enclosure.

Switchable Diversity
Choose between antenna-combining and true-diversity operation to suit the RF environment.

High-Density Operation
An alternate transmission mode supports more usable frequencies in congested locations.

Receiver Linking
Multiple receivers can share a single antenna pair for simpler system expansion.

Network Management
LINK connectivity enables remote monitoring and configuration through Wireless Manager.

Multipoint Reception
Networked receivers can follow the same transmitter and select the receiver with the strongest signal.

Onboard Audio Processing
Independent filtering, equalization and compression provide control over each audio channel.

Secure Transmission
Digital encryption helps protect wireless audio from unauthorized reception.

Spectrum Analysis
Built-in scanning tools assist with frequency planning and interference detection.

Infrared Synchronization
Compatible transmitters can receive system settings quickly during setup.

Mixed Audio Output
Both received channels can be combined when available input channels are limited.

Redundant Power
PoE+ can maintain operation if power from the AC adapter is interrupted.

Flexible Rack Installation
The included mounting hardware supports half-rack and paired full-rack configurations.

Software-Based Updates
Wireless Manager provides a centralized method for installing receiver firmware.
