The DADM226-UWB is an active antenna distribution system designed for Ultra-Wide-Band (UWB) applications. It features 15 selectable band-pass filters, providing coverage across a frequency range of 470-1045 MHz. This selective band-pass filtering effectively rejects out-of-band unwanted RF signals, ensuring better protection for the receivers.
The antenna inputs utilise BNC connectors, allowing the use of standard low-loss RF extension cables. The outputs consist of 12 mini-RF SMA connectors that feed the diversity receivers.
For applications requiring remote antenna power, the DADM offers user-switchable Mast-Head Amplifier (MHA) power, with red LEDs indicating the ON/OFF status. Power can be activated through the OLED display menu.
The DADM226-UWB has a very high input signal handling capacity with an exceptionally low noise figure and shows remarkable inter-modulation performance compared to other available low-power devices.
The tuning bandwidth can be selected by the user from a choice of 15 pre-programmed bands, allowing for adaptation to different applications and geographical locations. Additionally, the system gain is adjustable in 1dB increments, ranging from +5dB to -10dB, with 0dB representing unity gain. The DADM226-UWB is compatible with digital, hybrid, and analogue radio microphone receivers commonly available in the industry.
The DADM operates using a power source of 10-18 VDC, connected through a standard 4-pin HRS compatible connector at the DC input. It features six HRS DC output ports for powering auxiliary equipment, which can be turned on or off via the OLED menu. A green LED indicates the Power-On status of the system box, and the OLED display continuously shows the DC input voltage, functioning like a multi-meter.
Digitally tuned audio wireless and semi-broadband systems are the top choice for freelance sound engineers, rental companies, and major broadcasters in all wireless microphone applications.
