Audio Wireless Digitally Tuned Diversity Antenna Distribution Module (DADM226-DT-MK2)

Digitally Tuned Diversity Antenna Distribution Module DADM226-DT-MK2 designed to offer the solution specifically in crowded RF Spectrum to the antenna distribution requirements. Digitally Tuned Diversity Antenna Distribution Module DADM226-DT-MK2 is a custom design, which offers the solution specifically in crowded RF spectrum to antenna distribution requirements for portable sound bag applications. Designed for where the weight and size matters without sacrificing on performance. The Diversity Antenna Distribution Module DADM226-DT-MK2 covers frequency range 470-702MHz offering user selectable narrow RF-Bandwidth with high selectivity RF filters, to suit individual applications and frequency allocations. The Digitally tuned filters individually tuned in the frequency range 470-702MHz, user selectable in 8MHz step, 24MHz bandwidth with adjustable gain between 10dB to -10dB, user adjustable in 1dB steps. The DADM226-DT-MK2 offers custom tuned “Narrow-Band” RF Filtering for crowded spectrum and provides utmost protection against interfering signals maintaining robust RF integrity. The DADM226-DT-MK2 is an active antenna distribution system with user-selectable narrow-bandwidth band-pass filtering; eliminates multiple receiver antennas and provides a tidy solution for sound bags, carts, and trolleys with improved RF performance. There are two industry standard BNC input connectors for antenna inputs, enable use of standard low loss RF extension cables and 2 x 6 mini-RF SMA connectors feeding the diversity receivers. In applications requiring remote antenna powering, the DADM offers switchable active antenna powering, settings trough the OLED display menu, the RED LEDs indicating power ON/OFF status. The DADM226-DT-MK2 has an extremely high input signal handling capacity with extremely low noise figure and offers an outstanding inter-modulation performance when compared to other low power devices available. DC powering is through standard 4-pin Hirose type connector between voltages 10-18Vdc, an additional Hirose dc connector (HR2) can be user configurable as DC IN or DC OUT through the OLED menu. A green LED indicates power-on status of the system box, the OLED continuously displays dc input voltage. Audio Wireless Diversity Combiner/Distribution systems are now the first choice among freelance sound engineers, hiring companies as well as major broadcasters for all wireless microphone applications.
