AUDIO WIRELESS DA224-MB

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.

WIDE COVERAGE. FOCUSED RF PROTECTION. SELECTABLE FILTERING. CLEANER RF. GREATER CONFIDENCE

The DA224-MB gives you 28 selectable band-pass filters, helping prevent strong out-of-band interference from reaching your receivers. Select the RF band you need and create a cleaner, more dependable wireless environment - wherever the production takes you.

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.
