AUDIO WIRELESS DADM224-2C
A unique custom design for antenna combining, distribution and DC power distribution system. The DADM224-2C is a 4x IN and 2x 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 2x 4 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.
