Audio Wireless Diversity Antenna Distribution Module Single Band (DADM226-MK2-SB)

Frequency range 470-1154MHz, (custom tuned bands to order) One pair of antennae feeds up to six diversity receivers Custom Tuned band-pass filtering and signal splitters Remote antenna powering 6 x Hirose dc outputs User-adjustable system gain Industry standard connectors Intuitive OLED display menu and LED indicators Single power source solution Master ON-OFF switch Continuous system Voltmeter Soft ON/OFF switch for each individual Remote Antenna powering Soft ON/OFF switch for each individual Hirose dc output CNC machined aluminum custom design, lightweight and rugged – fits neatly in any sound bag Diversity Antenna Distribution Module DADM226-MK2-SB 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 matter without sacrificing performance. The DADM226-MK2 is a 2 IN and 2 x 6 OUT active antenna distribution system with custom-tuned 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 that enable the use of standard low loss RF extension cables, and there are 2 x 6 mini-RF SMA connectors feeding to the diversity receivers. In applications when remote antenna power is needed, the DADM offers switchable Active Antenna powering (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 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 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 the 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 the first choice among freelance sound engineers, hiring companies as well as major broadcasters for all wireless microphone applications.
