The Digitally Tuned Diversity Antenna Distribution Module (DADM226-DT-MK2) is a custom-designed solution for antenna distribution needs in crowded RF spectrums, particularly for portable sound bag applications. It is designed with an emphasis on minimising weight and size while maintaining high performance.
The Diversity Antenna Distribution Module DADM226-DT-MK2 covers a frequency range of 470-702 MHz, offering user-selectable narrow RF bandwidth with high selectivity RF filters to suit individual applications and frequency allocations.
The digitally tuned antenna distribution system is designed to operate within the frequency range of 470-702MHz, user-selectable in 8MHz steps. They have a 24MHz bandwidth with adjustable gain ranging from +10dB to -10dB, adjustable in 1dB steps.
The DADM226-DT-MK2 features custom-tuned "Narrow-Band" RF filtering, designed for crowded spectrums, ensuring maximum protection against interference while maintaining strong RF integrity.
The DADM226-DT-MK2 is an active antenna distribution system featuring user-selectable narrow-bandwidth band-pass filtering. This design eliminates the need for multiple receiver antennas and offers a clean solution for sound bags, carts, and trolleys, resulting in improved RF performance.
There are two industry-standard BNC input connectors for antenna inputs, enabling the use of standard low-loss RF extension cables and 2 x 6 mini-RF SMA connectors feeding the diversity receivers.
In applications that require remote antenna powering, the DADM provides switchable active antenna powering, settings through the OLED display menu, with the RED LEDs indicating the power ON/OFF status.
The DADM226-DT-MK2 handles high input signals with low noise and exceptional inter-modulation performance compared to other low-power devices.
DC power is supplied through a standard 4-pin Hirose connector, accommodating voltages between 10-18V DC. Additionally, an extra Hirose DC connector (HR2) can be configured as either DC IN or DC OUT via the OLED menu. A green LED indicates the power-on status of the system box, and the OLED continuously displays the 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.
