Visual Sound, Inc. On-Camera VHF Wireless Receiver WDR-PRO

Azden Corporation A VHF true diversity" receiver designed to help the videographer to create quality audio with less chance of dropouts. The nature of RF signals is such that they bounce off walls or structures creating "dead spots" or sudden loss of signal. The WDR-PRO with 2 selectable frequencies 2 front-end receivers inside the case and 2 antennas has been designed to overcome this inherent problem. Both receivers are set to the same frequency and the WDR-PRO's circuitry selects the receiver with the stronger signal from the microphone and accepts this signal. Hence less chance of dropouts. The LEDs on the WDR-PRO turn from red to green as one receiver and then the other receives a stronger signal. Optional mini-to-XLR and mini-to-1/4" phone plug cables are available. All receivers and transmitters in the "PRO" Series are on the same 2 frequencies (169.445MHz and 170.245MHz).
