Audio Wireless DADM228-P

The Diversity Antenna Distribution Module DADM228-P is a custom-designed, high-performance solution tailored for portable sound bag and sound trolley applications. It is specifically engineered to address the needs of antenna and power distribution in a compact and lightweight form, ensuring that it's easy to transport and set up without sacrificing performance.

This device is an active antenna distribution system, featuring 2 inputs and 16 outputs (2x8 configuration). Its primary role is to eliminate the need for multiple receiver antennas, thus providing a more organized and efficient setup. The integration of built-in band-pass filtering is a key aspect of the DADM228-P, enabling it to selectively filter out unwanted frequencies, which enhances the overall signal clarity.

The DADM228-P stands out for its high input signal handling capacity combined with a very low noise figure. This attribute significantly improves its inter-modulation performance, setting it apart from other low-power devices in the market. Additionally, it offers user-adjustable gain, ranging from +6dB to -10dB, adjustable in 1dB steps. This feature is crucial for optimizing the system's RF gain budget to accommodate different types of receivers, whether they are Digital, Hybrid, or Analogue.

In terms of connectivity, the DADM228-P is equipped with two standard BNC input connectors for antenna inputs, compatible with standard low-loss RF extension cables. For outputs, it includes 16 mini-RF SMA connectors to feed the diversity receivers. This makes it versatile and adaptable to various professional audio setups.

Another notable feature of the DADM228-P is its capability for remote antenna powering. It includes switchable MHA (Microwave Heating Applicator) powering, which can be controlled through an OLED display menu. This feature is complemented by RED LEDs that indicate the power ON/OFF status.

The antenna inputs of the DADM228-P are designed with a low loss, highly selective band-pass filter. This design is critical in ensuring that frequencies outside the tuning bandwidth are effectively rejected, further purifying the signal quality.

Powering the DADM228-P is straightforward and versatile. It operates on an external power supply ranging from 10-18Vdc, and the connection is made through a standard 4-pin Hirose connector. The power status is indicated by a green LED, and the OLED display continuously shows the DC input voltage. Moreover, the device includes 6 Hirose DC output connectors for powering auxiliary equipment in any sound bag, each of which can be individually controlled through the OLED menu.

The DADM228-P by Audio Wireless is increasingly becoming the first choice among freelance sound engineers, hiring companies, and major broadcasters for wireless microphone applications. Its combination of compact design, advanced features, and robust performance makes it a standout product in the field of professional audio equipment.
