AUDIO WIRELESS DADM226-DT-MKII-P
The DADM226-DT-MK2-P is an active antenna distribution system with user-selectable narrow-bandwidth band-pass filtering. It eliminates multiple receiver antennas and provides a tidy solution for sound bags, carts, and trolleys with improved RF performance. The DADM226-DT-MK2-P offers custom tuned "Narrow-Band" RF filtering as well as semi-broadband filters for crowded spectrum and provides utmost protection against interfering signals maintaining robust RF integrity. The DADM226-DT-MK2-P 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.
The DADM226-DT-MK2-P covers the frequency range of 470-702 MHz and offers 2 different modes of operation to suit individual applications and frequency allocations:
- DT-mode: digitally tuned very selective RF band-pass filter in the frequency range 470-702 MHz, tunable in 8 MHz steps, 24 MHz window, with adjustable gain between +10dB to -10dB user adjustable in 1dB steps.
- WB-mode: there are 3 settings for the high-pass filter (HPF) and 3 settings for the low-pass (LPF) filter, giving a combination of 9 semi-broadband filter bandwidths with adjustable gain between +6dB to -10dB user adjustable in 1dB steps.
There are two industry standard BNC connectors for antenna inputs and 2x 6 SMA connectors for feeding the diversity receivers. In applications requiring remote antenna powering, the DADM offers switchable active antenna powering.
DC powering is through standard 4-pin Hirose type connector (HR1). The DC power distribution is through HR2-HR5, the DC HR2 connector is user configurable as DC-IN or DC-OUT, HR3-HR5 is DC-OUT only, all functions are through the OLED menu. A green LED indicates the power-on status of the system box and the OLED display continuously monitors 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.
