DADM224

The Diversity Antenna Distribution Module DADM224 offers the solution to antenna and power distribution requirements for portable sound bags with its superior user adjustability functions. The DADM224 offers excellent rejection for interference free operation feeding up to four diversity receivers.

The DADM224 is fitted with 2x BNC as antenna inputs and 2x 4 SMA antenna output connectors. There are 2x 3 switchable DC Hirose power sockets that can supply DC power to other sound-bag or sound-cart equipments. Additionally, Audio Wireless or Micron receivers can be powered through the SMA antenna outputs.

User adjustable settings can be controlled via the intuitive OLED display menu to power remote antenna amplifiers, to switch HRS DC outputs ON/OFF, to adjust the gain of the antenna outputs with +6dB/-10dB and to turn receivers powered through SMA ON/OFF. The DADM224 operates within the frequency range of 470-715 MHz but can also be ordered within specific bandwidths.

The DADM224 is a CNC machined aluminium box, rugged and made to withstand daily use, finished in black anodising with clearly laser marked legends for long term readability.
