The AudioTechnica ATWDA49AEU is a rugged, rackmountable active UHF antenna distribution system delivering unitygain coverage from 470 to 990MHz. With two antenna inputs powering active antennas, four receiver outputs, and cascade support, it simplifies wireless setups while ensuring high OIP3 performance to maintain clean, interferencefree audio for multiple wireless receivers.
Wide Frequency Coverage: The ATW-DA49a operates across a broad UHF range of 470 to 990 MHz. This wide bandwidth supports many wireless systems, providing versatility for various applications.
Multiple Receiver Support: With two antenna inputs and four outputs per channel, this system allows one pair of antennas to feed multiple wireless receivers. It also includes a cascade output for expanding setups.
Active Antenna Power: Each antenna input supplies 12 V at 250 mA, powering active antennas or RF boosters directly. This simplifies installation and enhances signal strength.
High Intermodulation Immunity: The device offers a high third-order intercept point (OIP3) of +32 dBm. This feature reduces intermodulation distortion and ensures clean audio signals even in crowded RF environments.
Flexible Antenna Compatibility: The system supports both directly connected and remote antennas, adapting to different venue sizes and configurations. This flexibility improves wireless reliability.
Compact, Rack-Mount Design: Measuring 420 × 180 × 144 mm and weighing only 1.5 kg, the ATW-DA49a fits easily into standard 19-inch racks. Included rack ears facilitate quick mounting.
Wide Power Input Range: It accepts universal AC power from 100 to 240 V, converting it to 12 V DC via a switched-mode power supply. This ensures compatibility worldwide.
Expandable System Architecture: Cascade outputs allow daisy-chaining multiple units for larger wireless setups, making the system scalable to professional production needs.
