Q&A Q: What is the ARDM‑AES‑4OUT module?A: A professional audio output expansion module for compatible Marshall digital audio monitor systems. It provides extra digital audio exits from the monitor’s signal path. Q: What type of outputs does it offer?A: 4 unbalanced AES/EBU audio outputs on 75 Ω BNC connectors. Q: What audio formats can it handle?A: Outputs can carry de‑embedded audio from SDI sources or audio decoded from Dolby E/Dolby Digital bitstreams when paired with an appropriate decoder module. Q: How many channels does it support?A: Capable of routing four AES/EBU output pairs (eight audio channels) from selected groups in the monitor’s processing chain. Q: Which monitors is it compatible with?A: Designed for Marshall AR‑DM2‑L/AR‑DM21/AR‑DM32‑B audio rack monitors with modular expansion slots. Q: What’s the key benefit?A: Expands your monitor’s audio output flexibility with professional‑grade digital AES/EBU outputs, ideal for broadcast and pro‑audio environments. Q: Do I need any additional modules?A: To decode multi‑channel Dolby streams, an optional Dolby decoder module (ARDM‑D552) is required. Maintenance Tips Keep Audio & BNC Connectors Clean – Use compressed air or a soft brush to remove dust and debris. Avoid Cable Strain – Handle audio and BNC cables gently; prevent sharp bends or tension. Ensure Secure Installation – Firmly seat the module in the AR-DM2-L or compatible monitor slot. Use Quality Cables – Certified audio and BNC cables maintain optimal signal quality. Power Off Before Handling – Prevent electrical damage when installing or removing the module. Inspect Regularly – Check connectors, cables, and module for wear or looseness. Protect from Dust & Moisture – Store in a clean, dry environment when not in use. Test Audio Signal – Periodically verify proper signal transfer to ensure consistent performance.
