Audio Wireless DADM224-2C Diversity Antenna Combiner and Distribution
Diversity Antenna Combiner and Distribution Module DADM224-2C is a custom design, which offers the solution to antenna combining, antenna distribution and dc power distribution requirements. Designed for where the weight and size matters without sacrificing on performance.
The 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 useradjustable gain stage at each RF input. The DADM224-2C enables the user to cover 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 enables use of standard low loss RF extension cables, and there 2 x 4 mini-RF SMA connectors feeding the diversity receivers. Each antenna input can be individually turned ON/OFF via OLED menu when not used, a LED indicator showing the status of each Antenna input.
In applications when remote antenna powering is needed, the DADM224-2C offers individually switchable Remote Antenna powering with RED LEDs indicating power ON/OFF status, the MHA powering can be turned ON/OFF through the OLED display menu. The DADM224-2C 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 with a semi-broadband response to suit varying applications; each antenna input gain is individually user adjustable in 1dB steps between +6dB to -10dB, the DADM224-2C is compatible with digital, hybrid and analogue 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 4 x Hirose dc output connectors available for powering auxiliary equipment. 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.
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.
