The ATW-DR3240DAN is a Dante-enabled 4-Channel receiver for the D50 digital UHF wireless system. This half-rack receiver operates in one of two switchable RF modes: normal mode (Antenna Combining Diversity) or robust mode (MRC True Diversity) for greater RF stability. Up to four receivers can be linked and operated without antenna distribution, requiring only a single pair of antennas. Plus, the system’s HD (high-density) mode gives users the option of expanding the number of usable frequencies from the standard 17 within a 6MHz TV channel block to 47 frequencies in HD, a feature that can be especially useful in the congested RF environments of large cities.
