AUDIO WIRELESS DADM226-MKII multi-band
Diversity antenna distribution module DADM226-MK2 is a custom design, which offers the solution to antenna and power distribution requirements for portable sound bag applications. Designed for where the weight and size matters without sacrificing on performance. The DADM226-MK2 is a 2 IN and 2 x 6 OUT active antenna distribution system with 20 pre-programmed band-pass filtering: user adjustable system gain, the DADM226-MK2 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 which enables use of standard low loss RF extension cables and there 2 x 6 mini-RF SMA connectors feeding the diversity receivers. In applications when remote antenna powering is needed, the DADM offers switchable MHA powering with RED LEDs indicating power ON/OFF status, the MHA powering can be turned ON/OFF through the OLED display menu.
The DADM226-MK2 has a very high input signal handling capacity with very low noise figure and offers an outstanding inter-modulation performance when compared to other low power devices available. The tuning bandwidth is custom designed to suit all popular radio microphone receivers available in the industry. The DADM is externally powered between 10-18Vdc, the dc input connector is an industry standard 4-pin Hirose and there are 6 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 power-on status of the system box and the OLED display continuously displays dc input voltage. Powering for the multiple receivers can be powered through the DC Hirose output sockets. The dc output ports can be turned ON/OFF from the OLED display menu. Audio Wireless wide tuning range systems are now first choice among freelance sound engineers, hiring companies as well as major broadcasters for all wireless microphone applications.
