Audio Wireless Digitally Tuned Mini DA224-MB-UK/DME (470-1154MHz)
The DA224-MB is an advanced, digitally tuned active antenna distribution system designed to enhance wireless microphone performance. It offers user-selectable band-pass filtering across a broad frequency range of 470-1260MHz. This selective filtering ensures out-of-band rejection, thereby shielding connected receivers from unwanted or “dirty” RF signals.
Antenna inputs are industry-standard BNC connectors for diversity receivers.
Key Features
- User-selectable Multi-Band Digitally Tuned Band-Pass Filtered Design: The system offers flexibility with a choice of pre-programmed bands tailored for different applications and geographic locations.
- Lightweight Construction: The DA224-MB boasts a compact and lightweight CNC-machined aluminium chassis, making it ideal for use in portable sound bag setups.
- True Antenna Diversity: Supports 4-way true diversity antenna operation, ensuring robust RF signal integrity.
- Advanced RF Filtering: Covers the 470–1260MHz spectrum with advanced filtering to protect signal quality.
- Gain Control: System gain is user-adjustable in 1dB increments between +6dB* and -21dB, with 0dB set as unity gain.
- Active Antenna Powering (AAP): User-switchable powering for remote antennas, with orange (red and green lit) LED indicators denoting ON/OFF status via the OLED display menu.
- Monitoring and Indicators Features Include:
- User Interface: Navigation and adjustments are through tactile switches (UP, DOWN, SET), with the SET button doubling as the ON/OFF switch.
- Active Antenna Powering Orange (both Red and Green lit) LED
- Received Signal Strength Indicator (RSSI), Green LED
- 50dB RSSI gauge metering - RSSI Bars for A and B antennas
- Signal overload (OL) RED LED
- Continuous system dc voltage monitoring via OLED display menu setting
