The DADM226 Diversity Antenna Distribution Module DADM226 offers antenna and power distribution with built-in bandpass filtering.
The active antenna distribution system eliminates multiple receiver antennas to provide a tidy sound bag solution and improve RF performance. Two BNC input connectors are provided for antenna inputs and 2 x 6 mini RF SMA connectors feed the diversity receivers.
In applications when remote antenna powering is needed, the DADM offers switchable MHA powering which can be turned ON/OFF through the OLED display menu.
The DADM226 has a very high input signal handling capacity with very low noise. The tuning bandwidth is delivered in one of four wideband responses to suit varying applications: 470-715MHz, 470-622MHz, 510-622MHz, or 600-715MHz; please specify when ordering.
The DADM is externally powered between 10-18V DC with a 4-pin Hirose and there are three Hirose DC output connectors available for powering a mixer/recorder or auxiliary equipment Each DC output port can be individually turned ON/OFF.
Powering for the multiple receivers is simplified by means of offering phantom power at each SMA RF connector; each Audio Wireless (AWDR-1) receiver is individually powered through the antenna socket, eliminating additional cabling in the sound bag. The phantom power is user selectable and can be turned ON/OFF.
