Diversity Antenna Distribution Module DADM228-P is a custom design, which
offers the solution to antenna and power distribution requirements for portable
sound bag and sound trolley applications. Designed for where the weight and
size matters without sacrificing on performance.
The DADM228-P is a 2xIN and 2x8 OUT active antenna distribution system with
in-built band-pass filtering; the DADM228 eliminates multiple receiver antennas
and provides a tidy sound bag solution with improved RF performance.
The DADM228-P 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 system box offers, +6dB to -10dB gain user adjustable in 1dB steps to suit
individual applications. The user adjustable gain offers flexibility optimizing
system RF gain budget to suit, Digital, Hybrid and Analogue receivers.
There are two industry standard BNC input connectors for antenna inputs which
enables use of standard low loss RF extension cables, and there 2x8 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 antenna inputs compromise a very low loss very selective band-pass filter
designs to reject unwanted frequencies below and above the tuning bandwidth.
The DADM is externally powered between 10-18Vdc, the dc input connector is
an industry standard 4-pin Hirose, a green LED indicates power-on status of the
system box and the OLED display continuously displays dc input voltage.
The DC distribution is with 6xHirose dc output connectors for powering auxiliary
equipment in any sound bag. Each dc output port can be individually turned
ON/OFF through the OLED menu.
Audio Wireless Diversity Antenna and dc power distribution systems are now
first choice among freelance sound engineers, hiring companies as well as
major broadcasters for all wireless microphone applications.
