Audio Wireless DADM226 DT

Digitally Tuned Diversity Antenna Distribution Module [DADM226-DT V2] offers the solution to the antenna and dc power distribution requirements for portable sound bag applications.
Custom designed for where the weight and size matter without sacrificing performance.
The Diversity Antenna Distribution Module DADM226-DT is designed to cover the frequency range 470-750MHz offering user-selectable RF filters. There are 4-Modes of operations to suit individual applications and frequency allocations.

DT - Mode 1: Digitally tuned very selective RF Band-Pass filter in the frequency range 470-702MHz, tunable in 8MHz step, 24MHz window, with adjustable gain between +8dB to -8dB


WB - Mode 2: Fixed window semi-broadband band-pass filter 470-750MHz


DADM226-DT V2 offers the flexibility and the solution to any antenna distribution system where utmost protection against interfering signals is needed. It is compatible with any radio microphone receivers available in the industry.


The Digitally Tuned DADM is a 2 IN and 2 x 6 OUT active antenna distribution system with in-built selectable band-pass filtering; the DADM226-DT eliminates multiple receiver antennas and provides a tidy sound bag solution with improved RF performance.
There are two industry-standard BNC input connectors for antenna inputs that enable the use of standard low loss RF extension cables, and there are 2 x 6 mini RF SMA connectors feeding the diversity receivers.


In applications when remote antenna power is needed, the DADM offers switchable Active Antenna Powering with RED LEDs indicating power ON/OFF status, the powering can be turned ON/OFF through the OLED display menu.


The DADM226-DT has a very high input signal handling capacity with a very low noise figure and offers an outstanding inter-modulation performance when compared to other low power devices available.


The DADM is externally powered between 10-18Vdc, the dc input connector is an industry-standard 4-pin Hirose and there are 3 x Hirose dc output connectors available for powering any auxiliary equipment in any sound bag. Each dc output port can be individually turned ON/OFF through the OLED menu. A green LED indicates the power-on status of the system box and the OLED display continuously displays dc input voltage.


Audio Wireless wide tuning systems are now the first choice among freelance sound engineers, hiring companies as well as major broadcasters for all wireless microphone applications.
