A unique custom design for Antenna Combining, Distribution, and DC Power Distribution system. The Audio Wireless DADM224-2C is a 4 IN and 2 x 4 OUT active antenna combiner and distribution system with in-built low loss band-pass filtering, LNA and user-adjustable gain stage at each RF input. The DADM224-2C enables the user to cover a 2-zone wider area with improved RF reception, the DADM224-2C eliminates multiple receiver antennas and provides a tidy sound bag, cart, and trolley set-up applications with improved RF coverage and performance. There are four industry-standard BNC input connectors for antenna inputs that enable the use of standard low loss RF extension cables, and there are 2 x 4 mini-RF SMA connectors feeding the diversity receivers. Each antenna input can be individually turned ON/OFF via the OLED menu when not used, with a LED indicator showing the status of each Antenna input. The four switchable DC Hirose power sockets supply dc power to sound bag or sound cart equipment. DADM224-2C is a CNC machined aluminum box to withstand daily location work, finished in black anodizing with clear laser marked legends for long-term readability.
