£665.83 (incl. VAT £799.00)

Audio Wireless DADM224 is an Antenna and Power Distribution system that offers excellent rejection for interference free operation feeding up to six Diversity Receivers.

User adjustable settings can be controlled via the intuitive OLED display menu to power remote antenna amplifiers, to turn each receiver ON/OFF and to turn Hirose dc output volts within the frequency range from 470 – 715MHz the DADM224 is fitted with 2 x BNC as Antenna inputs and 2 x 4 SMA Antenna output connectors with switchable Remote Antenna Powering. The three switchable DC Hirose power sockets supply dc power to sound bag or sound cart equipments.

DADM224 is a CNC machined aluminium box to withstand daily location work, finished in black anodising with clearly laser marked legends for long term readability.
