Whenever I need to buy new kit this is the place to go. Wendy and her team have excellent knowledge of the equipment they supply, access to information from manufacturers about the kit and an attitude to genuine customer service that is not often found in today's globalised corporate world. I have dealt with all the main UK broadcast suppliers and buying from Wendy's is by far the best experience.

KEY FEATURES:
The DADM226-UWB is an Ultra-Wide-Band active antenna distribution system with Pre-Programmed 15-Bands user selectable Band-Pass filtering operating over 470-1045MHz range. Selective Band-Pass filtering provides out-of-band rejection of unwanted dirty RF signals and protection to the receivers.
The antenna inputs are BNC connectors which enables use of standard low loss RF extension cables, and the outputs are 2 x 6 mini-RF SMA connectors feeding the diversity receivers.
For applications requiring remote antenna power, the DADM provides user-switchable MHA (Mast-Head-Amplifier) power, with RED LEDs showing ON/OFF status. Power can be activated via the OLED display menu.
The DADM226-UWB has an extremely high input signal handling capacity with exceptionally low noise figure and offers an outstanding inter-modulation performance when compared to other low power devices available.
The tuning bandwidth is user selectable from a choice of pre-programmed 15-Bands to suit varying applications and geographical location; the system gain is user adjustable in 1dB steps between +5dB to -10dB (0dB setting being the UNITY Gain), the DADM226-UWB is compatible with digital, hybrid and analogue radio microphone receivers available in the industry.
The DADM uses a 10 -18Vdc power source via a standard 4-pin Hirose input, with six Hirose DC outputs available for auxiliary equipment. The DC output ports are turned on or off from the OLED menu. A green LED indicates Power-ON status of the system box, and the OLED display continuously displays dc input voltage – multi-meter.
Audio Wireless digitally tuned, and semi broadband systems are now first choice among freelance sound engineers, hiring companies as well as major broadcasters for all wireless microphone applications..
