The Audio-Technica ATW-DA49A 4-Channel Antenna Distributor is a 470-990 MHz active unity-gain distribution system featuring cascade outputs for channel expansion, power for active antennas, and high OIP3 (+32 dBm) for intermodulation protection.
The Audio-Technica ATW-DA49A 4-Channel Antenna Distributor is a UHF active unity-gain diversity antenna distribution system designed to streamline wireless microphone setups. This unit enables a single pair of antennas to feed signal to as many as four wireless receivers simultaneously. It operates across a broad frequency range from 470 MHz to 990 MHz, ensuring compatibility with Audio-Technica wireless systems and various third-party wireless equipment.
The ATW-DA49A utilizes a unity-gain design to maintain consistent signal strength across the distribution network. This architecture prevents signal amplification or attenuation, which preserves original audio integrity. To ensure reliable performance in RF-heavy environments, the system features a high Output Third-Order Intercept Point (OIP3) of +32 dBm. This specification provides maximum protection against intermodulation, maintaining a clean signal for all connected receivers.
The distribution system supports both directly connected and remote antenna configurations using standard BNC connectors. Each of the two antenna inputs provides 12 V DC at 250 mA. This integrated power supply allows the unit to drive active antennas or inline antenna boosters without requiring external power sources for those components.
Engineered for professional installations, the ATW-DA49A includes four dedicated antenna outputs and one cascade output per channel. The cascade outputs facilitate the connection of additional distribution systems, allowing for easy channel expansion in larger wireless installations. This scalability ensures the system can grow to meet the demands of complex RF environments.
