Audio Wireless Diversity Antenna Distribution Module (DADM224-MK2-P)

The DADM224-MK2-P is a unique custom design that offers the solution to antenna distribution requirements for portable sound bags. Its custom-tuned RF filters offer excellent rejection for interference-free operation feeding up to four diversity receivers.

User-adjustable settings can be controlled via the intuitive OLED display menu to adjust the system gain and to power remote antenna amplifiers. The DADM224-MK2-P is fitted with 2x BNC inputs (with active antenna powering) and 2x 4 SMA antenna output connectors. The four switchable DC Hirose power sockets supply dc power to the sound bag or sound cart equipment.

The housing is a CNC machined aluminum box to withstand daily location work, finished in black anodizing with clear laser marked legends for long-term readability.
